LCR-II Troubleshooting Guide To comply with Weights & Measures requirements, it is necessary to start and stop each delivery with a fully packed hose. Normally, this will be the case. However, there are times where the hose is not fully packed (e. g. after a preset delivery). As such, the hose must be packed and the register zeroed prior to making the next delivery. NOTE: This procedure will not work for an empty or dry hose.
LCR-II Troubleshooting Guide NOTE: Check for proper operating voltages before changing the circuit board. If the circuit board needs to be changed, be sure to remove all power to the LCR-II. 5. If an error occurs during a delivery, the message "*FAULT: PRINT DIAGNOSTICS TICKET*" will appear on the delivery ticket. The diagnostic ticket will contain an error message that can be useful in troubleshooting. Print a diagnostic ticket by moving the red Selector Switch to "SHIFT PRINT" for less than two seconds.
LCR-II Troubleshooting Guide PROBLEM PROBABLE CAUSE “Power Failure” Power to LCR-II interrupted appears on Lap during delivery. Pad or diagnostic ticket. Static discharge. SOLUTION 1. Check accessory power cable for damage. Ensure that the power, common and ground wires (11, 12 and 13) on power connector J6 are secure. J6 is located on the rear of the circuit board. 2. Turn on all truck accessories (headlamps, 2-way radio, heater, etc.).
LCR-II Troubleshooting Guide PROBLEM PROBABLE CAUSE Product flow Pulser shaft is not turning with does not register product flow. on Lap Pad or Pulser failure. LCR-II display “Pulser Failure” appears on the diagnostic ticket or on the Lap Pad display. Missing pulse counts. Excessive reversals. SOLUTION 1. Manually spin the pulser shaft and monitor the LCR-II display. 2. If the LCR-II display counter increments, this may indicate a mechanical problem.
LCR-II Troubleshooting Guide PROBLEM PROBABLE CAUSE SOLUTION Valve will not open. Solenoids are inactive or inoperative. 1. Insert a delivery ticket into the Epson printer and start a delivery. Foreign debris in system. 2. Move the selector switch from RUN to STOP and back to RUN. Listen for an audible clicking sound from the solenoids. 3.
Appendix A - Compensation Types & Parameters The table below shows the supported methods of calculating the Volume Correction Factor (VCF). The method is independently selectable for each product in Product Calibration. The table below shows the valid temperature ranges for each table. The hold temperature, Thold, is the temperature that VCF is held at for temperatures < Thold and > Tmin. This is done to allow compensation in very cold environments where further extrapolation of equations is not allowed.
Appendix B - Operation Using VT 100 Compatible Terminal If the LCR-II is operated using a VT 100 compatible terminal (instead of the LC Lap Pad), refer to the following chart for the terminal keystrokes that correspond to the Lap Pad keystrokes. VT 100 communication parameters that must be observed include: • • • • • Baud Rate (9600) Data Bits (8) Parity (None) Stop Bits (1) Flow Control (None).
Appendix C - Error Messages The LCR-II was designed to perform diagnostic analysis of problems as they occur. If an error should occur, one of the following messages may be displayed on the Lap Pad or printed on a Diagnostic Ticket (see troubleshooting section). The list below explains the error message and any possible corrective action. The LCR-II was designed to handle most foreseeable problems on its own.
Appendix C - Error Messages DIAGNOSTIC MESSAGE LIST If an error occurs during a delivery, the message "*FAULT: PRINT DIAGNOSTICS TICKET*" will appear on the delivery ticket. The appropriate message below is then printed on the diagnostic ticket if an error has occurred. A diagnostic ticket is printed by loading a ticket into the printer and then moving the Selector Switch to the SHIFT PRINT position for less than two seconds.
