11 User Guide LSC-B 1.0 INTRODUCTION This User Guide provides a system overview describing the hardware installation and introduces the processor Configuration Software, utilised for interrogation, setup and modification of the system's operating parameters. A more comprehensive User Guide accompanies the Configuration Software which describes the configuration of the software in detail and provides information about the processing operations. The Landscan Control Batch processor can be used with Landscan LSP series or Landscan LS series equipment, the selection of a system determined by the setting of jumper links on the X13 PCB. Page 1

12 RS 23 2 TERMIN AL X XX.XX X.XX X.XX LSC-B User Guide 2.0 SYSTEM OVERVIEW The Landscan Control Batch Processor provides a dedicated data input, mathematical processing facility for use with Landscan sensor heads for process control applications. The processor provides external communications interfaces for system configuration and for the transmission of scan line information to host computers. This can be achieved using RS232C or an Ethernet connection when the transmission of large quantities of data at high speed is required. In addition, the Landscan Control Batch Processor provides optional digital and analogue I/O, allowing the processor to perform process monitoring and control. The processor has been designed to function automatically and continuously with in-built self-analysis of system events, plus comprehensive diagnostic information accessible through the configuration software and front panel display. The processor supports up to four simultaneous Ethernet connections. In addition, the processor captures data from any of the Landscan heads and manipulates the information into a 2-dimensional analysis grid. The system can be considered to consist of two distinct components, the Control Batch Processor and the Configuration Software which runs on a portable PC and is used to configure the processor parameters.

13 User Guide LSC-B 2.1 Landscan Control Batch Processor The Landscan Control Batch Processor is a rackmounted unit, that will sample 1000 data points per scan line, at scan speeds between 10Hz and 100Hz. The processor can partition the previous product temperature data into up to 500 analysis fields. Within each of these fields, processing functions are applied including min, mean, max and standard deviation. An analog 4 to 20mA output is provided that allows for remote control of the Landscan sensor head's emissivity settings. An additional alarm relay output is available to alert the user to conditions which may result in the data captured being invalid. (e.g. power loss at the Landscan sensor head) The product edges can be detected by identifying where in the scan line the temperature rises above a preset threshold level. This is achieved automatically by analysing the peak product temperature in relation to the environmental background temperature. The system uses the edge detection information to align the field positions, allowing the fields to track a target which may be moving erratically within the sensor s field of view. If the target moves, grows or shrinks within the sensor s field of view, the fields follow these movements. Optional analogue and digital I/O can be used to provide process monitoring and control. The processor provides an RS232 serial communication connection located on the front panel, which allows a laptop personal computer or similar to be connected temporarily to allow modifications to the system configuration. A second RS232 serial communications connection can be used for permanent monitoring. Ethernet communication is also provided on the processor to allow the connection of third party computer systems and also the Landscan WCA software. Calibrated temperature data and zone processed data are available in real time for the purposes of analysis and database storage by remote computer systems. Configuration of the processor is fully supported by the Ethernet and RS232C communications, with the configuration software capable of setting up the processor for an appropriate network setting. When the user has satisfactorily configured the system for a particular application, the parameters essential for operation are secured against power loss inside the system. The processor will continuously operate without interruption, utilising these settings until parameter changes are requested by the user. 2.2 Configuration Software The Configuration Software enables the user to communicate with the processor for initial setting up of the operating parameters and provides limited process monitoring capability. All operating parameters are securely retained in the non-volatile memory of the processor. The Configuration Software features; Configuration of: Scanner Type, Processor, Ethernet, Zones and Alarms, Optional Analogue and Digital I/O, Product Detection, Heater Fields and Heater Groups. Displays: Profile, Zone and Alarm Status, Scanner Status, Zone Profile, 2D Map, Product Display and Heater Field Display.

17 User Guide LSC-B 4.3 Mains Power The processor requires a three-wire a.c.supply, that includes an earth ground connection. Warning RISK OF ELECTRIC SHOCK The a.c. supply and associated wiring must conform to local regulations for voltage and power rating. Failure to provide an earth ground connection can cause electric shock and improper operation of the equipment. Ensure that the earth ground wire has a current carrying capacity equal to, or greater than the largest power conductor. Ensure that the a.c. supply to this equipment is connected through an accessible isolator switch. The power consumption of the Landscan Control Batch Processor is approximately 60W and the unit must be fused independently with a 5amp fuse. Earth Live Neutral Fig. 4 - IEC Mains Socket Wiring Diagram 4.4 Encoder Input (X1) This 37-way 'D' type connector allows the interface of an incremental encoder (Land part no ) to the processor. The encoder input can be used for process correction in rotary applications and process speed corrections in linear applications. 4.5 Encoder I/O (X2) This 37-way 'D' type connector allows the interface of up to two external digital input sensors (Land part no ) to the processor. The input signals from these sensors can be used to define start and stop parameters of a product as it passes the scanner head. Page 7

18 LSC-B User Guide 4.6 External Communications - Ethernet (2-off) (X6/X7) The ethernet connections (2-off) provide a high-speed communications interface. The user is able to request live data and remotely configure the processor parameters from a remote PC. To make use of the external communications, commands must be sent to the processor using the LAND specified format. Full details of the LAND messaging interface are given in the Processor Configuration Software User Guide. The processor provides a connection for a 10BASE-T RJ45 Shielded Twisted Pair (STP) connector of CAT5 specification. The general cable recommendation is to use shielded 10BASE-T LSOH Category 5/Level 5 STP cable.this provides protection from electromagnetic interference in industrial environments. The use of unshielded 10BASE-T LSOH Category 5/Level 5 UTP is only recommended for areas that are guaranteed to be free from severe electromagnetic interference. The maximum cable length allowed is 100m / 328ft, which may be extended by utilising external network repeaters. For single head, single display systems, a 'peer to peer' network crossover cable is recommended. X6/X Fig. 5 - Ethernet Connection 4.7 External Communications - RS232C Connection (X9) The serial connection provides the means by which a user can request statistical data and remotely configure the processor parameters from a remote PC. To make use of the external communications, customers must send commands to the processor using the LAND specified format.

This number is the lowest digit of the IP addresses stored in the unit for each of the two network adapters. XXX.XXX.XXX.XX_ On power-up, the unit then reads the switch and creates the unit's IP addresses from the base address plus the switch setting. For example, if the base address of the unit was and the switch setting was 5 the actual IP addresses used by the unit would be and This allows for all units on the network to be configured with the same base address and have a unique switch setting. Using this system allows units to be moved around the network without the need to use configuration software to change network settings. The base address of the unit can be changed using the Configuration Software, details of which are explained in the Configuration Software User Guide. Note The switch is only read on power-up of the unit and any changes to the switch position, following this, does not change the network IP address. It is therefore necessary when applying power to the unit, to ensure that the IP switch setting is in the relevant position. Page 16

31 User Guide LSC-B 8.0 ROTARY MACHINE APPLICATIONS 8.1 Overview On systems where a scanner head is utilised on a rotary machine, it is necessary to correct the image as it appears in the scanner field of view, because of distortion caused by the rotational effect. To calculate this correction, the LSB requires a positional input and a machine reference point, that allow the processor to determine the current position of the product relative to the scanner datum. The positional input is provided by a rotary encoder and the machine reference point by a digital input sensor. 8.2 Installation of Hardware Scanner To allow the rotary geometry correction to be applied to the product data, the scanner head must be positioned in the correct orientation. The following criteria must be met; The scan line is aligned with the centre of the machine. The scanner height must ensure a given scan width slightly greater than the maximum product size Encoder To ensure maximum efficiency of the machine encoder, the following criteria must be met; The encoder should ideally be positioned as far away from the centre of the machine as possible. This ensures that the greatest measurement circumference and the highest possible position resolution are achieved. The encoder measurement wheel must remain in contact with the machine for the full machine revolution. The encoder mounting bracket should be fitted with the contact spring compressed to approximately 50% of its full compression (approx. 25mm). This ensures that the spring maintains tension between the machine surface and the measurement wheel during movement in both directions Digital Input sensor To ensure maximum efficiency of the digital input sensor, the following criteria must be met; The magnetic digital input sensor should be mounted onto the machine such that it provides a trigger signal to the processor, just prior to one of the product stations passing through the scanner field of view. The magnet should be positioned on the rotating section of the machine, with the sensor mounted to a fixed point between 10mm and 20mm from the magnet. The sensor incorporates an indicator lamp which illuminates when the sensor and the magnet are positioned and activated correctly. 8.3 Software The setup and configuration of the hardware used in a rotary machine application is carried out utilising the Landscan Configuration software. The use of this software is described in detail in the Landscan Configuration Software User Guide and the accompanying on-line help facility. Page 21

33 User Guide LSC-B 10.0 MAINTENANCE The Landscan Control Batch Processor requires no scheduled maintenance, but it is recommended that the unit is kept clean and free from any contaminants. The processor cabinet utilises two internal fan assemblies to continuously circulate air around the components of the processor. The air intake for these fans has a cover assembly containing a filter that requires changing when found to be contaminated. The following procedure details how to replace the cabinet filter: Ensure that the power to the processor is turned off. Remove the M3 countersunk slot-head screws (x4) from the air intake cover. Remove the filter cover assembly (cover, filter and filter grill) from the processor cabinet air intake. The removed items should easily dismantle, allowing the contaminated filter to be replaced. Place the new filter into the recess in the filter cover and position the filter grill on top of the filter. When the filter cover assembly is correctly positioned over the air intake, secure using the M3 screws. Apply power to the unit and ensure that the cabinet fans are functioning correctly. Note It is important that the cabinet filter is changed when required. Failure to do so may result in component overheating and subsequent damage. Page 23
