5 Programming Instructions To access the programming buttons and LCD display, remove 4 cover screws and open the hinged cover. Upon initial power up of the module, the display shows: Version 1.xx subject to change without notice The next screen shows the status of the transducer: If no magnet is detected, the display will also show No Transducer Detected and the red error LED will be on. Once the module has been powered and completed self testing, the screen will look similar to the screen below. Also, if the module and transducer are working properly, both the green program LED and the red error LED will be off. List of Factory Default Value Settings: To enter the Configure Mode, press the <PGM + DOWN> keys simultaneously for at least 3 seconds. Configure Mode allows the user to adjust the following parameters: 1. Adjust LCD contrast - Press the <UP> or <DOWN> keys repeatedly to adjust display contrast. Press <PGM> to continue to the next parameter. 2. Set Display Units - For the LCD to display raw position values in Hexadecimal (HEX), press the <UP> key for System Units. For the LCD to display raw position in Decimal, press the <DOWN> key for Normal. Press the <PGM> key to exit Configure Mode, and return to Run Mode

6 To enter Programming Mode, press <PGM + UP> keys simultaneously for at least 3 seconds. Programming Mode allows the following parameters to be set: 1. Set Units - The display shows the position value in either Millimeters or Inches. For Millimeters press the <UP> key, for Inches, press the <DOWN> key. The default value is Inches. Press <PGM> to continue to the next parameter. 2. Adjust Update rate - This menu allows the update rate to be set (Sampling Rate) to either 1mSec or 2mSec. For a 1mSec update rate, press the <DOWN> key. For a 2mSec update rate, press the <UP> key. The default value is 1mSecs. Press <PGM> to continue to the next parameter. 3. Adjust Gradient - Enter the gradient of the transducer. The gradient value is found on the Balluff transducer label in µs/in (e.g. grad=8.8843µs/in). Initially the gradient value is set to µs/in with the last digit blinking. Press the <UP> key to increment this value to the desired setting. Press <SEL> to move the cursor to the next digit. Press the <UP> and <DOWN> keys to adjust each digit. Continue this process until all of the digits are set according to the gradient value marked on the label. Press <PGM> to continue to the next parameter. 4. Adjust Nominal Stroke - This menu allows the operator to enter the Nominal Stoke length of the transducer. This will also adjust the NULL and GAIN values to approximate settings. Exact setting of the NULL and GAIN values will be set during the Online Adjust Mode programming. Initially the value is set to in, with the cursor blinking in the least significant number. Adjust this value accordingly, using the <UP> and <DOWN> keys. Press the <SEL> key to advance to the next significant number. Follow this process until the value is correctly entered. Press <PGM> to continue to the next parameter. 5. Set PWM State - This will allow the Pulse Width Modulated output signal to be either Active high or Active low. For Active high, press the <UP> key. For Active low, press the <DOWN> key. The default state is Active low. Press <PGM> to continue to the next parameter. Note - This step is not needed if only the analog output is being used

7 6. Adjust Number of Recirculations - The number of recirculations of the PWM output signal can be set between 1 and 16, default is 01. Use the <UP> or <DOWN> key to adjust the number to the desired value. Press <PGM> to continue to the next parameter. Note - This step is not needed if only the analog output is being used. 7. Set Analog State - This allows the user to program the slope of the analog output voltage. Press the <UP> key for Output Rising (-10 to +10Vdc) or press the <DOWN> key for Output Falling (+10 to -10 Vdc). Rising and falling values are based on the magnet reading starting at the Null position closest to the electronics. The default setting is Output Rising. Press the <PGM> key to exit Programming Mode and return to Run Mode. To enter Online Adjust Mode, press the <PGM> key for at least 3 seconds. Online Adjust Mode allows you to set the Null, Gain and PWM Offset values. Note - Due to possible voltage drops across the cables, the Null and Gain value should also be checked at the input of the controller with a 6 digit multi-meter for accuracy. The voltage value on the display represents the Analog Output Voltage seen directly on the Output of connector J1, pin D. 1. Adjust Null - Locate the magnet to the Null location, towards the housing of the transducer. The Null value may adjusted anywhere between Vdc & Vdc. Press the <UP> key to increase the Null, press the <DOWN> key to decrease the Null. The Analog Output Voltage is updated accordingly on the display. Press <PGM> to continue to the next parameter. Note - If no transducer is detected on power up, the display will show V. 2. Adjust Gain - Locate the magnet to the Gain position, towards the end of the transducer rod (side that is away from the transducer housing). The Gain value may be adjusted from above the set Null value (example -10 Vdc) up to +10 Vdc. Press the <UP> key to increase the Gain, press the <DOWN> key to decrease the Gain. The Analog Output Voltage is updated accordingly on the display. Press <PGM> to continue to the next parameter. Note If no transducer is detected on power up, the display will show V. Note You must repeat the Online Adjust Mode steps 1 and 2 until the voltages required at the Null and Gain locations are set to desired values. 3. Adjust PWM Offset - This step allows the pulse width of the PWM output signal to be adjusted. To setup the PWM signal, locate the magnet at the NULL location. Pressing the <UP> key will increase the pulse width of the PWM signal, pressing the <DOWN> key will decrease the pulse width. The PWM pulse width is updated accordingly on the display. Note - This step is not needed if only the analog output is being used. When the PWM Offset is properly set at the NULL point, press <PGM> to exit the Online Adjust Mode and return to Run Mode
