26 Chapter 1 Introduction Before You Call Global Support Customers sometimes incur unnecessary costs when they call Kronos Global Support and request that a CSR come out to their site before checking some basic things at the Series 400 terminal. If you are having a problem, do the following: Check the physical connections; for example, check the LED lights and the link lines. Check the connections of any plug-ins. Verify the terminal configuration; for example, is the terminal s password and IP address correct? Also, verify the procedures you used to configure the terminal. Check the network connection; that is, check the link on the port that the terminal is connected to at the hub or switch and verify the circuit and wiring. Ping the terminal from the host PC if your terminal has a Token Ring or Ethernet board. If you can ping the terminal, but it still won t collect or update data, check to see if it is a duplicate IP address problem. To do this for a terminal with an Ethernet board, unplug the Ethernet cable from the back of the terminal. If you can still ping the terminal, another device shares the IP address. For information on how to ping the terminal, see the section Ping Utility in Chapter 4. If you cannot ping the terminal, the PC host may be communicating to the terminal through a switch or some other device. Caution If you change anything, and the problem still exists, go back to the original situation. Do not try to change something else at that point, because you may introduce another problem. If you are still having problems after trying all of the above, contact Kronos Global Support by calling HELP ( ), or visit Kronos Incorporated

27 Chapter 2 Preventive Maintenance The Series 400 terminal requires periodic preventive maintenance to ensure trouble-free operation.

85 Power-Up Failures Power-Up Failures If the Series 400 terminal does not power up, then one of the following assemblies may be faulty: DC wall supply APS (if using distributed power over communications lines) LCD display Mainboard Use the following steps when troubleshooting problems that occur when powering up the terminal: 1. Check the Power Status LED, the bottom indicator light on the Series 400 terminal. This light illuminates if the terminal is receiving adequate power. If it does not illuminate, proceed to step 3. If the LED illuminates, but the terminal does not power up, go to step Check the LCD display: a. Remove the AC power from the terminal. b. Disconnect the LCD display s cable from connector P2 on the mainboard. c. Connect a functioning display board to connector P2 on the mainboard. d. Supply AC power to the Series 400 terminal. If the terminal powers up properly, install the functioning display board in the terminal. If the terminal does not power up, proceed to step Using an AC voltmeter set to 150 VAC (or set to 250 VAC for a 220 VAC line), measure the AC voltage. Measured voltages must be in these tolerance ranges: AC hot to ground measures 108 to 132 VAC AC hot to AC neutral measures 108 to 132 VAC AC neutral to ground measures 0 to.5 VAC If the measured AC voltages are not within range, locate another AC power source. Series 400 Terminal Maintenance and Troubleshooting Guide 4-7

86 Chapter 4 Troubleshooting 4. Verify that the DC wall supply is good: a. Check to see that the DC wall supply is plugged into the Series 400 terminal s power connector and to an AC wall outlet. If the wall supply is not plugged in properly, plug it in securely. b. Unplug the DC wall supply from the terminal, but not from the wall outlet. c. Using a voltmeter, measure the DC voltage across CR6. The voltage should measure approximately VDC. If the voltage is present, and within tolerance, then proceed to step 5. If DC power is not present, then replace the DC wall supply with a functioning one. 5. If using distributed power over the communications lines, verify that the APS is installed properly. If the APS is not installed properly, reinstall it properly. If using distributed power over the communications lines, verify that the APS is supplying the proper DC voltage. With the APS connected to an AC power source, measure the voltage output at pin 3 of its network connector. This voltage should measure +36 VDC (+/- 5%). If the APS is outputting the proper voltage level, then proceed to step 6. If the APS is not outputting the proper voltage level, then replace it with a functioning one. 6. If, after performing all of the above steps, the terminal still does not power up properly, replace the mainboard with a functioning mainboard. 4-8 Kronos Incorporated

87 Badge-Reading Problems Badge-Reading Problems If the Series 400 terminal is experiencing badge-reading problems, the source of the problems can usually be traced to one of the following: Bar code badges are unreadable or the badge is out of specification. Remote badge reader is improperly connected to the terminal. Integral or connected badge reader is malfunctioning. The Series 400 terminal is improperly configured for the connected badge reader(s), company ID code of the badges being read, or the bar code symbologies being read. Mainboard is malfunctioning. Use the following procedure to troubleshoot badge-reading problems: 1. Using maintenance mode command 152, verify that the Series 400 terminal can read badges in maintenance mode. Configuration settings are sometimes the cause of badge reader problems. Using maintenance command 152 can cause confusion in diagnosing these problems. Command 152 bypasses configuration settings, and problems that exist while in normal mode can be missed while in maintenance mode. For example, all bar code symbologies are temporarily enabled when command 152 is used, and any configuration setting using Procedure 11 to disable a symbology is ignored. Try using command 10 while operating in guard or supervisor mode. If the badges read properly using command 152 and not command 10, then the problem is in how the Series 400 terminal is configured. Check the settings in Procedures 12, 13, and 14. For more information, see the Series 400 Terminal Configuration Guide. 2. Clean the integral swipe badge reader. 3. Inspect the bar code badges that are being read. If badges are being scraped off, you may need a wider-slot reader. Contact Kronos Global Support. If the badges are damaged in any way, replace them with functioning badges. If the badges are good, then proceed to step 4. Series 400 Terminal Maintenance and Troubleshooting Guide 4-9

88 Chapter 4 Troubleshooting 4. If the connected wand, CCD, handheld laser bar code reader, or remote reader is malfunctioning, follow these steps: a. Disconnect the bar code reader from the Series 400 terminal and connect a functioning reader in its place. b. Attempt to read some badges using the functioning reader. If the terminal fails to read the badges, proceed to step Verify that the Series 400 terminal is configured properly for the attached badge reader(s), the bar code symbologies being read, and the company ID code of the badges being read. Ensure that the bar code symbology that you are attempting to read has been enabled in Procedure 11. The remote reader converts any badge into the Code 128 bar code symbology. Be sure this symbology is not disabled when using a remote reader. Ensure that the correct badge reader type has been enabled in Procedure 1, Step 2. The badge reader only reads the bar code default (3) or generic (4) unless it is a PIN only unit. Ensure that the correct company ID code has been enabled in Procedure 29. For information on these procedures and steps, see the Series 400 Terminal Configuration Guide. Change these program mode values if necessary and then reconfigure the Series 400 terminal. Attempt to read some badges or bar codes after reconfiguring the terminal. If the bar code reader still fails to work properly, proceed to step Check the I/O board if external devices are being used. Replace if defective. 7. If, after performing all of the above steps, the Series 400 terminal still does not read badges, replace the mainboard with a functioning mainboard Kronos Incorporated

89 Keypad Problems Keypad Problems Constant or intermittent keypad problems can usually be attributed to one of the following: Keypad is malfunctioning Mainboard is malfunctioning Use the following procedure to troubleshoot keypad problems: 1. Execute maintenance mode command 154 to test the keypad. 2. Press a key on the keypad. Its corresponding character(s) should appear on the terminal s LCD. If not, proceed to step Press Clear twice to abort. 4. Determine if the keypad s ribbon cable is properly connected to the mainboard: a. Open the Series 400 terminal s front cover. b.

Series 400 Terminal Maintenance and Troubleshooting Guide 4-11

90 Chapter 4 Troubleshooting Lead-Acid Battery Backup Failures Failure of the Series 400 terminal s 12 VDC lead-acid battery backup option can be traced to one of the following problems: The battery backup option is installed improperly. The battery backup board s battery-charging circuit is not functioning properly. The lead-acid battery is not holding a charge properly. The battery backup board s sensing circuitry is not functioning properly and is failing to switch the terminal s power source to the lead-acid battery when external power is lost or interrupted. If at any time the 12 VDC lead-acid battery backup option fails to provide backup DC power to the Series 400 terminal when its external power source is lost or interrupted, you should isolate the source of this failure by following these steps: 1. Inspect the Series 400 terminal and ensure that its lead-acid battery option is installed properly: a. Ensure that the battery backup board s black cable is connected to the battery s negative (-) terminal and that its red cable is connected to the battery s positive (+) terminal. b. Ensure that the battery backup board s mainboard cable is connected to connector TB3 on the mainboard. c. Ensure that fuse F1 on the battery backup board is not burned out. If it is, replace it with a 5.0A/125V glass fuse (part number ). d. Ensure that the battery backup board s three cables are soldered to the board properly. 2. With the Series 400 terminal connected to its external power source, ensure that the battery backup board s battery-charging circuitry is functioning properly: 4-12 Kronos Incorporated

91 Lead-Acid Battery Backup Failures a. Using a Kronos field service battery tester (part number ), or a standard multimeter, measure the charge voltage supplied to the lead-acid battery while it is connected to the battery backup board. Place the battery tester/multimeter s probes across the lead-acid battery s positive and negative terminals. b. If this voltage measures less than 12 VDC, then either the lead-acid battery is failing to hold its charge or the battery backup board s battery-charging circuitry is failing. If the voltage measures 12 VDC or greater, go to step 3. c. Replace the lead-acid battery with a functioning battery, and re-measure the voltage. For more information, see the Testing and Replacing the Lead-Acid Battery section in Chapter 2. If the voltage again measures less than 12 VDC, the battery backup board s battery-charging circuitry is not functioning properly. Leave the functioning battery in place as the original battery cannot hold a charge properly. 3. With the Series 400 terminal s battery backup option installed and connected, remove external power from the terminal by unplugging its communications cable connector. Note This step applies only to power over communications set ups; otherwise, you should remove the wall supply. Observe the terminal s power status LED (the bottom yellow LED). If the LED is flashing, the battery backup board s sensing circuitry is functioning properly. If the power status LED is not lit, the battery backup board s sense circuitry is not functioning properly, and the terminal is not being switched over to battery backup when external power is lost or interrupted. Replace the battery backup board with a functioning board. Series 400 Terminal Maintenance and Troubleshooting Guide 4-13

92 Chapter 4 Troubleshooting Communications Problems A single Series 400 terminal or a network of terminals can experience the following communications problems: Serial problems Ethernet problems Token Ring problems Modem problems Serial, Ethernet, and Token Ring troubleshooting information is described in this section. For information on troubleshooting modem problems, see the Kronos Terminal 14.4Kbps Modem Option Installation Guide. Serial Troubleshooting The source of serial communications problems can usually be traced to one of the following: Improper communications cabling Improper RS-485 network termination and biasing Improper configuration of the Series 400 terminal s communications parameters (baud rate, start/stop bits, etc.) Faulty communications hardware Use the following procedure to troubleshoot communications problems: 1. Speak with the system administrator or someone who is familiar with the installation and obtain a specific explanation of the problem. If the customer is running Timekeeper Central Version 5 or earlier, type the ERRLOG.TKC file to the host PC and look for any communication error messages. If the customer is running Timekeeper Central Version 6 or later from the Kronos Central Controller shell program, type the Activity History Report and look for any communications error messages Kronos Incorporated

93 Communications Problems 2. Examine all communications cables and ensure that they are connected correctly to all devices on the network and are routed properly. 3. When troubleshooting a network of daisy-chained Series 400 terminals using RS-485 communications, ensure that the network is properly terminated and biased. 4. Run the SETCOMM.EXE and CHECK.EXE utility programs on the host PC and establish its baud rate and COMM port configuration. 5. Use the TRYIT.EXE, ATRYIT.EXE, and COMMSTAT.EXE utility programs to test communications between the host PC and each terminal on the network. Attempt to isolate the communications problems to a single Series 400 terminal by using TRYIT.EXE. 6. Ensure that the communications parameters of each terminal on the network match those of the host PC. The Series 400 terminal s configuration parameters are set using Procedures 9, 10, and 30 of the terminal program. 7. Check the password to ensure that there are no duplicates in the network. 8. If the communications problems can be isolated to a single terminal, use the following maintenance mode commands to test the terminal s communications hardware: Command 136: Reinitialize Communications Hardware Command 175: Channel A Transmit Test Command 176: Channel A Echo Test Command 177: Channel A External Loopback Test Command 178: Channel A Local Loopback Test Command 179: Channel A Remote Loopback Test Command 138: Test Internal Modem Module (with modem option only) Command 180: Channel B Transmit Test (with I/O board option only) Command 181: Channel B Echo Test (with I/O board option only) Command 182: Channel B External Loopback Test (with I/O board option only) Command 183: Channel B Local Loopback Test (with I/O board option only) Series 400 Terminal Maintenance and Troubleshooting Guide 4-15

94 Chapter 4 Troubleshooting Command 184: Channel B Remote Loopback Test (with I/O board option only) For information on the commands themselves, see Chapter 6, Using Maintenance Mode. 9. If the Series 400 terminal fails any of the maintenance commands listed in step 5, replace its mainboard. Note The RS-232 communications port on the optional I/O board may be configured to perform host communications. This feature is useful in the event of host communications port failure. See the I/O board documentation for more information. Ethernet Troubleshooting You can use the Ping utilty and the Tryit utility to test Ethernet communications. Ping Utility You can test the communications to an Ethernet terminal using the PING.EXE utility program, which is supplied with your installation diskette. The PING.EXE utility can send a signal from the host computer to a Series 400 terminal that has an Ethernet option attached. You can run this program from the installed directory to check the communications to terminals. The command line for PING follows: ping password [-frequency] [-s] [-b] [-?] where password is the 6-digit terminal password and frequency represents the frequency number of a continuous test. Ping assumes that the first two octets of the IP address are the same; therefore, you can only ping terminals which share these first two octets. The optional parameters are: -f invokes a continuous test. You must specify a frequency rate for this 4-16 Kronos Incorporated

95 Communications Problems option. -s displays statistics of the tests such as number of successful tests. -b removes the audio -? displays help on the command line usage For example, if you want to ping a terminal with the password , type: ping If you are unable to successfully ping a terminal, consider the following: Is this a new terminal? An upgraded terminal? Has it ever worked before? Have you verified that the IP address has been entered correctly in the application? Have you checked the terminal s configuration for the proper IP address (Procedure 30, Step 2)? Can you ping other devices on that same segment? If not, contact the the customer Network Administrator or IS personnel. Have you tried to ping the terminal from a host PC on the same segment as the Terminal? If you are experiencing either of the following situations: You have just put in a new Ethernet daughtercard and it will not work and you cannot Ping it. You have just replaced a Series 400 terminal with a new one using the same IP address and it will not work and you cannot ping it. there is a good chance that the host PC is communicating to the terminal through a switch or some other device that builds an Address Resolution Protocol (ARP) table. In this case, it is possible for the switch or other device to still have the IP address of this terminal mapped to the physical address of the original Ethernet daughtercard. You can ask the Network Administrator for a number of things for a workaround: New IP address (they can use the old IP address immediately for another device). To remove the entry from the Switch database (ARP table) Series 400 Terminal Maintenance and Troubleshooting Guide 4-17

96 Chapter 4 Troubleshooting To put a static entry in the switch database (ARP table) If you are able to ping an Ethernet terminal, but software communication fails, run the Tryit utility to further test the communications. Tryit Utility The Tryit utility tests the communication line between the host computer and Timekeeper terminal by establishing a communication link. This utility is part of the Terminal Service Utility application. For more information about this application, see the section Terminal Service Utility in Chapter 3. From the Terminal Service Utility window, select Tools > Tryit. The Tryit dialog box appears: When running Tryit, you must specify the Ethernet IP address. When you click the Test button, the results of the test appear in a message box. Communication is successful when Tryit identifies terminal and version number; otherwise a failure message displays Kronos Incorporated

97 Communications Problems If communication fails, check all cables from the host computer to the Series 400 terminal; also check the passwords and IP addresses. For more information on Ethernet communication, as well as RS-485, RS-232, modem, and twinaxial communication, see the Terminal Communication Network Reference Guide. Token Ring Troubleshooting If you are having difficulty with Token Ring communications, perform a visual inspection of the printed circuit board assembly for damaged components. 1. Ensure that the Series 400 terminal is set for RS-485 communications and biasing and termination. 2. Verify that the following communication parameters are set: Baud rate = 9600 bps (Procedure 10, Step 1). Turnaround delay, data bits, and parity settings add up to 132 (Procedure 10, Step 2). IP address is set up correctly (Procedure 30, Step 2). Network speed is 4 or 16 Mbits (Procedure 10, Step 10). Use Procedure 91 to reset the terminal so that the setting takes effect. 3. Verify that the password (Procedure 30, Step 1) is set to default (all spaces). 4. Check the LEDs on the Token Ring board. There are three LEDs you can use for troubleshooting: LED 3 = power LED 2 = 4 MB LED 1 = 16 MB When the terminal powers up, LEDs 1 and 2 pulse once. All LEDs are off while the field programmable gate array (FPGA) loads. LED 3 comes on Series 400 Terminal Maintenance and Troubleshooting Guide 4-19

98 Chapter 4 Troubleshooting when the software starts to initialize and load the T1 chip. LED 2 or 3 comes on when you attach the board to the ring. Under normal conditions with a 16 MB network connection, LEDs 1 and 3 are on and LED 2 is off. Under normal conditions with a 4 MB network connection, LEDs 2 and 3 are on and LED 1 is off. Under the following fault conditions, here is the status of the LEDs: No network connection: LEDs 1 and 2 are off and LED 3 pulses. No terminal RS-485 communication: LEDs 1 and 2 pulse. Incorrect network speed: LEDs 2 and 3 pulse and LED 1 can be either on or off. 5. Ping the terminal s IP address, not its password; for example: ping For more information about how to ping the terminal, see the section Ping Utility earlier in this chapter. If you can ping the terminal, but it still will not update or collect data, go to step Check for a duplicate IP address by unplugging the NIC cable from the back of the terminal and pinging the IP address of the terminal again. If the ping is successful, you know that another device shares that IP address. If you are experiencing either of the following situations: You have just put in a new Token Ring interface board and it will not work and you cannot ping it. You have just replaced a Series 400 terminal with a new one using the same IP address and it will not work and you cannot ping it. There is a good chance that the host PC is communicating to the terminal through a switch or some other device that builds an Address Resolution Protocol (ARP) table. In this case, it is possible for the switch or other device to still have the IP address of this terminal mapped to the physical address of the original Token Ring interface board Kronos Incorporated

101 Chapter 5 Changing Terminal Firmware This chapter provides instructions for using the SL400 utility to modify the time and attendance application stored in the Series 400 terminal s flash-eeprom. This chapter describes the following information: Using the Correct Versions Softloading an Application with SL400

102 Chapter 5 Changing Terminal Firmware Using the Correct Versions Before attempting to use a utility to update the flash application in your Series 400 terminal, check the versions of the items described in this section. About the Flash Utility If you are using DOS, use either version 8D.00.03G (or higher) of the SL400.EXE utility or version 8D00.03G (or higher) of the SOFTLOAD.EXE utility to update the Series 400 flash application files. Earlier versions of these utilities cannot properly load.kre files or.kra files. If you are using a Windows system, use the SL400 utility of the Kronos Terminal Service Utility (TSU) application, Version 2A or higher. Note that you can also use the TSU Softload utility to update the flash. About the Boot-EPROM The boot-eprom of your Series 400 terminal is identified by a version stamp of KOS.XXXX, where the XXXX indicates the release version; for example, KOS.2A00 or KOS.2A01. Maintenance command 110 gives you the boot-eprom version. If the boot-eprom version of the Series 400 terminal is KOS.2XXXX, your terminal s mainboard s number is XXX, and you can only softload flash application programs with the file name 400XXXX.KRN. If the boot PROM version of your terminal is KOS.3XXX, your mainboard s number is XXX, and you can only softload flash application programs with the file name 400XXXX.KRE. 5-2 Kronos Incorporated

103 Using the Correct Versions About the Flash Application Program The flash application program is identified by a version stamp of 400.XXXX, where the XXXX indicates the release version; for example, 400.3B02 or 400.3B03. Maintenance command 110 gives you the version. The Ethernet option board has its own flash application program device that controls the higher level Ethernet communications functions, and this flash is also intended to be field upgradeable using the softload process. Ethernet flash programs are identified by the alphanumeric version followed by a.kra extension; for example, ETH1A01.KRA or ETH1A02.KRA. If you softload the wrong flash file type or use an earlier version of SL400.EXE, or you use SOFTLOAD.EXE to softload a 400XXXX.KRE or ETHXXXX.KRA file, the softload fails somewhere in the middle of Block 1. If you allow the softload process to complete after a failure occurs (this may take a few minutes of seeming inactivity), SOFTLOAD and SL400 terminate the softload process appropriately, and the terminal returns to boot mode; that is, the terminal displays KOS.XXXX. You can then softload the proper flash file using the correct version of SOFTLOAD or SL400 and activate the file without incident. Warning If you break the communications link and you cold-start the terminal before the Series 400 terminal is restored to boot mode; that is, while the terminal displays the SOFT LOAD MODE... message, a serious problem can occur. The terminal returns to boot mode but can be in a state where you must return it to the Repair Depot before the correct flash application can be softloaded and activated. Symptoms of a problem include seeing the ERROR 50 message, or the terminal reporting that it is a 460 when in fact it is a 480 or a 420. If this happens, you must return the terminal to the Repair Depot. It cannot be fixed in the field. Series 400 Terminal Maintenance and Troubleshooting Guide 5-3

104 Chapter 5 Changing Terminal Firmware Softloading an Application with SL400 Kronos periodically releases new versions of its time and attendance applications. It is possible to upgrade a Series 400 terminal s flash-eeprom with a new time and attendance application by softloading the application over the communications lines connected to the terminal. If a Series 400 terminal is connected to a modem, it is even possible to upgrade the terminal from a remote site. Kronos provides a SL400 service utility for Windows and DOS systems that you can use to softload an application or to save and restore data. For more information on saving and restoring data, see the section, Saving and Restoring Data, in Chapter 3. SL400 for Windows Use the Windows SL400 utility, which is part of the Terminal Service Utility (TSU) application, to softload an application into the Series 400 terminal s flash-eeprom. For more information about the TSU application, see the section Terminal Service Utility in Chapter 3. Follow these steps to softload the Series 400 terminal with a time and attendance application flash: 1. Save the data in the Series 400 terminal by following the steps in the section Saving and Restoring Data in Chapter 3. Note The Setcomm utility in the TSU application creates a configuration file called COMMLINK.CFG in the TSU directory. 5-4 Kronos Incorporated

157 Error Messages Error Messages Error 01: BADGE READ ERROR The Series 400 terminal could not read the badge correctly, or the bar code symbology is not enabled in the terminal program. Clean the reader and test the other badges. If the badge is properly encoded, make sure that the bar code symbology has not been disabled (Procedure 11). Error 03: USE FUNCTION KEY The Series 400 terminal is set so that simple time and attendance punches are disabled. The terminal only accepts punches that have a function key associated with it. This is usually a requirement of the host software. If this behavior is not desirable, change the associated parameter in the Series 400 terminal program using Procedure 5, Step 3, Value 8. Error 04: REPUNCH RESTRICTION The Series 400 terminal rejected a punch because the elapsed time since the employee last punched is less than the repunch interval. There are separate repunch intervals for home and non-home employees. The home employee repunch interval comes from either a restriction profile or a parameter in the terminal program (Procedure 7, Step 1). Non-home employees always have the terminal program parameter applied to their punch (Procedure 7, Step 2). A possible cause of Error 04 is that the terminal time was set to some time in the future, some punches occurred, and then the time was corrected. All punch data stored by the Series 400 terminal can be erased to prevent this error. Erasing data should be done with extreme caution, as all collected and uncollected first in, first out (FIFO) data is included. Maintenance mode command 130 will erase all FIFO data and all current schedule data for all Series 400 Terminal Maintenance and Troubleshooting Guide A-3

158 Appendix A Error and Status Messages employees; however, this data does not include individual schedules for employees, just data reflecting that an employee is currently working a shift. Error 05: PUNCH RESTRICTED The Series 400 terminal rejected a punch because, according to the schedule enforcement information stored in the terminal, the employee is not authorized to punch at this time. The restriction profile includes generic and individual schedules to which the employee is assigned. Error 06: UNKNOWN EMPLOYEE The Series 400 terminal rejected a punch because the employee assigned to this badge or PIN number is not a home employee. The badge inserted has the correct company code, but is not valid at this terminal. You also get this error on the 400 model (not on the 420 or 405 models) when you swipe a badge that is not for a home employee, and cross-punching and access control features are not enabled. Use the employee list to verify employee terminal assignments. To enable the punching of non-home employees, change the setting for Procedure 22 in the terminal program to enable non-home employees to punch, according to their restriction level. Error 07: OFF TIME The Series 400 terminal rejected a punch because it is configured with an off-time that includes the current time of day. If this behavior is not desirable, do the following: Ensure that the off-times are correct, and that the day-of-week exclusion(s) are correct. Refer to Procedure 21, Steps 1 through 4 of the terminal program. Check to see if the punch requires gate access but the current time is during a gate off-time. Refer to Procedure 21, Steps 5 through 12. A-4 Kronos Incorporated

159 Error Messages Error 08: PUNCH RESTRICTED The Series 400 terminal rejected a punch because the restriction level encoded on the badge does not match the restriction template parameter in the terminal program. This applies only to non-home employees. Refer to Procedure 22, Step 1, of the terminal program. Error 09: HOME EMPLOYEE A supervisor used a home employee s badge while executing supervisor command 5. This command is intended for non-home employees; supervisor command 2 is the corresponding command for home employees. Error 10: BADGE DATA ERROR The badge that was swiped was decoded but contains invalid data. For a Kronos standard badge, this could include the wrong company code, out-of-range values for one of the three 1-of-7 code fields, and the wrong checksum for a code 3-of-9 badge. If the badge is not a Kronos standard badge, it is a generic badge. You must use the Series 400 terminal program to configure the terminal to accept generic badges. The following are relevant procedures in the terminal program: Use Procedure 1, Step 2 to enable the use of employee generic badges. Use Procedure 1, Steps 4 through 6 to define characteristics of the employee generic badge bar code. Use Procedure 5, Step 3, Value 64 to enable use of badges for departments and labor accounts. Use Procedure 24, Steps 1 through 3 to define characteristics of the labor accounts for generic bar code badges. Use Procedure 24, Steps 4 through 12 and Steps 14 through 25 to define characteristics of the labor level generic bar code badges (seven labor levels). Set nonzero values in Procedure 24, Steps 4 through 12 to enable the use of expanded labor tracking fields. Series 400 Terminal Maintenance and Troubleshooting Guide A-5

Error 11 occurs on the 420 terminal model when a simple punch badge ID does not result in a gate opening (home employee or gate lists). The 405 terminal model returns Error 11 when it rejects a badge ID because it is not on the deduct lists. Error 12: PUNCH RESTRICTED The Series 400 terminal rejected a department/labor account/labor level badge because the restriction level encoded on the badge does not match the department badge restriction template specified in the terminal program (Procedure 22, Step 2). Error 13: OUT OF RANGE Error 13 is associated with changing parameter values in the Series 400 terminal program and displays in any of the following situations: The combination of settings for a generic bar code badge size, date size, and number of digits to ignore is invalid. Values for employee, department, labor level, and labor account generic bar code badge settings is invalid. The badge size of a labor level badge is set to that of the labor account badge. Error 14: DEPARTMENT BADGE The Series 400 terminal rejected a badge swipe because the badge number is on the department validation list or on one of the labor level validation lists. The terminal is expecting an employee badge swipe. A-6 Kronos Incorporated

161 Error Messages If this behavior is not desirable, change the setting of Procedure 5, Step 3, in the terminal program to 128. Exclude the weighted value of 128 to turn off this feature. Error 16: OUT OF RANGE Error 16 is associated with changing parameter values in the Series 400 terminal. Possible reasons for this error message are: The generic bar code data size is longer than the maximum possible length. The data size specified for the labor account badge does not match the combined data size settings of the labor levels. Error 18: (sent to host PC) The Series 400 terminal rejected host command 90 (Set Terminal Program) because the terminal is operating in program mode. Do the following: Use host command 99 to force the Series 400 terminal into normal mode. Use host command 90 to edit the terminal program s parameters as desired. For details on host commands, see the Series 400 Terminal Host Software Interface Guide. Error 19: (sent to host PC) The Series 400 terminal rejected host command 10 or 11 (Add Home Employee) because the maximum number of home employees the terminal can accommodate has been reached. Do the following: Check the setting for Procedure 4, Step 1 or Step 7, which determines the maximum number of home employees the terminal can accommodate. This can be done through host command 89. Use host command 120#25# to verify that all home employees in the list belong in the list. For the syntax of the host commands, see the Series 400 Terminal Host Software Interface Guide. Series 400 Terminal Maintenance and Troubleshooting Guide A-7

162 Appendix A Error and Status Messages Error 20: LIST ITEM NOT FOUND The Series 400 terminal could not find the list item you are trying to modify or delete. Note Use of error 20 was discontinued in a later flash version. Any attempts to delete items that are not in the list are no longer considered to be an error. If a modify request is anticipated, and the entry is not already in the list, the attempt is treated as an add. Error 21: LIST NOT FOUND The specified list could not be found or the list number you specified is not valid. Error 22: LIST FULL The specified list (to add to) is full. The validation list has the maximum number of items. Check the Series 400 terminal program setting for the allowable number of entries. See the Series 400 Terminal Configuration Guide to determine which procedure in the terminal program to check. Error 23: (sent to host PC) No memory is allocated for this list. Change the appropriate parameter in the Series 400 terminal program to allocate memory for the list. See the Series 400 Terminal Configuration Guide to determine which procedure in the terminal program to check. Error 24: ERROR A change to a list size limit or other memory allocation parameter (translation text) will not fit in the memory available in the terminal. Check values for the A-8 Kronos Incorporated

163 Error Messages terminal program, or try using the memory sizing utility MEM400 (described in the Series 400 Terminal Configuration Guide). Error 26: OVER CREDIT LIMIT Error 26 is associated with the model 405 Employee Debit Terminal (EDT). The employee attempting a debit transaction is marked by the host system as over their credit limit. Therefore, the terminal does not allow the employee to perform the transaction. The employee may still perform credit transactions. Error 27: WILL NOT BE SPLIT Error 28: EMP S SPLIT FULL These two error messages display together and are associated with model 405 Employee Debit Terminal (EDT). The errors indicate that an employee attempting a debit transaction has reached the maximum number of pay period splits. Large purchases can be split across multiple pay periods, but these messages warn the employee that this transaction will not be split across multiple pay periods. The transaction is accepted and is forwarded to the host. Error 30: NEED BADGE This message appears when an employee attempts to enter a personal identification number (PIN) at the Series 400 terminal while PIN entry is disabled. The employee must swipe a badge at the Series 400 terminal instead. If you enable PIN entry using the terminal program (Procedure 5, Step 1, Value 1), you can also prevent home employees from using PINs (Procedure 16, Step 3) based on their restriction profile. For details on the procedures, see the Series 400 Terminal Configuration Guide. Series 400 Terminal Maintenance and Troubleshooting Guide A-9

164 Appendix A Error and Status Messages Error 36: WARNING FIFO FULL This message is displayed when an operator tries to enter data at a terminal when the first in, first out (FIFO) buffer is full. All punch attempts will be rejected until the FIFO is collected and flushed. Do the following as soon as possible: Use host command 100 (Send Complete FIFO) to send data from the terminal Use host command 110 (Clear FIFO) to flush the data from the terminal. For information on using host commands 100 and 110, refer to the host application collection of data and to the Series 400 Terminal Host Software Interface Guide. Error 41: INVALID SCHEDULE The Series 400 terminal rejected a punch attempt by a home employee because the host software has not sent schedule enforcement information to the terminal. Schedule information includes restriction profiles and generic schedules and allows the terminal to determine whether to accept a punch. Error 42: CONFIG CONFLICT This error is associated with changing parameter values in the Series 400 terminal program. The current settings indicate that the shorthand notation feature is enabled (Procedure 25, Step 4), but there is no memory allocated for the labor account list (Procedure 26, Step 7). Use Procedure 26, Step 7 to allocate memory for the labor account list. Error 43: CONFIG CONFLICT This error is associated with changing parameter values in the Series 400 terminal program. The current settings indicate that the shorthand notation feature is enabled (Procedure 25, Step 4), but one of the prompt sequence settings (Procedure 24, Step 13; Procedure 25, Step 8; Procedure 25, Steps 10 through 13; Procedure 44, Steps 1 through 13) is not compatible with the labor levels enabled (Procedure 25, Steps 1 through 3). Another reason for this error message could be A-10 Kronos Incorporated

165 Error Messages that the value in Procedure 25, Step 4 is greater than the number of enabled labor levels. The Series 400 terminal now supports seven labor levels, but still supports use of just three labor levels. The settings mentioned in the previous paragraph are valid for configurations not using any of the new labor levels. Procedure 33 was added to specify prompting sequences to support all seven labor levels (not just the new labor levels). For details on the procedures, see the Series 400 Terminal Configuration Guide. Error 44: NOT ALLOWED This error is associated with the break enforcement feature. A home employee attempted an in-punch, but the time since the corresponding out-punch is shorter than the minimum set in the Series 400 terminal program. The feature is enabled based on the restriction profile associated with the home employee (Procedure 69, Steps 1 through 15), the shift length, minimum break, and minimum meal are determined when the shift first starts (Procedures 61 through 68, Steps 1 through 15). Error 50: ERROR The Kronos Options Package (KOP) value stored in the Series 400 terminal indicates that the downloaded software is for the wrong product (400 versus 550). Contact Kronos Global Support. Another reason for this error message could be that the wrong Softload file was sent to the terminal. The flash application starts and determines that the KOP bit settings do not agree with the flash application version (420 versus 460). Error 59: ERROR The baud rates set in the Series 400 terminal program for host communication (Procedure 10, Step 1) and printer communication (Procedure 9, Step 2) are not compatible with the hardware (DUART). If both baud rates are greater than 9600, ensure that they are set to the same rate. Series 400 Terminal Maintenance and Troubleshooting Guide A-11

166 Appendix A Error and Status Messages This error is also returned when maintenance command 138 is executed to test the integral modem, and the terminal cannot communicate with the modem. The modem is either inoperable or not installed. Error 60: TABLE FULL While executing host command 65 (Create/Edit Bell Schedule Table), the Series 400 terminal determined that the time of day for the bell does not exist in the current bell schedule, and that the bell table contains the maximum number of entries (fixed at 48). If necessary, use host command 65 to edit the bell schedule as needed. For information on host command 65, see the Series 400 Terminal Host Software Interface Guide. Error 61: INVALID BELL TIME The bell time specified does not exist in the bell schedule, or the time entered is not a valid time of day. Error 62: NOT INSTALLED The action the user attempted involves bells or gates, but they are not enabled in the Series 400 terminal program. Use of both bells and gates is only possible if the optional I/O daughterboard has been installed. This error can be seen when using host commands 65, 66, 120#58#, 121, 122, 123, 124, 129; and maintenance commands 6, 7, l1, 14, 17, 65, 66. This error is also returned if maintenance command 118 is used to interrogate the integral modem, but the integral modem is not enabled. See Procedure 9, Step 1 to enable the integral modem. Error 63: ERROR A hardware problem was detected when the Series 400 terminal was turned on. Contact Kronos Global Support or your Customer Service Representative. A-12 Kronos Incorporated
