“power failure”
appears on
diagnostic ticket
or LCR 600 shuts
down unexpectedly.
1.
Power to LCR 600
interrupted during
fueling.
1. Ensure the LCR 600 was not manually turned off during
an active fueling.
2. Static discharge. 2. Check accessory power cable for damage. Ensure that
the power, common and ground wires (11, 12 and 13) on
power connector J6 are secure.
3. Turn on all truck accessories (head lamps, 2-way radio,
heater, etc.). Engage the hose reel and monitor the DV
voltage at J6 using terminal 11 as positive and terminal
12 as ground. If the voltage drops below 10 VDC, the
truck electrical system may not support the LCR 600.
4. Verify proper grounding of the LCR 600. Refer to the
installation manual for proper grounding procedures.
Epson printer
release light
flashes.
1. Low voltage to the
Epson printer.
1. Check the battery voltage for a minimum of 12.6 VDC.
2. Under extreme cold conditions, the printer may not
operate. Warm up the cab of the vehicle.
3. If the release light continues to flash, replace the Epson
295 Printer (PN E49001) with a functional printer.
4. If the light still flashes, replace the 825001 printer power
cable
no power indicator
lights to the Epson
printer.
1. No power to the Epson
printer.
1. Verify that the power switch is in the ON position. This
switch is located on the left-hand side of the Epson 295
printer.
2. Check the printer power cable (PN 825001) to ensure
that it is seated in the port properly. If the problem
persists, replace the power cable.
3. If the problem continues replace the Epson printer (PN
E49001) with a functional printer.
“temperature
Error” appears on
diagnostic ticket or
on the LCR 600.
1. Open or shorted circuit
between the RTD probe
and LCR 600.
1. Remove terminal block J14 from the circuit board. On
the terminal block, measure and record the resistance
between the following pins:
TERMINAL # CoNTINuITy
J14 #20 to #22 100 Ω ±20 Ω
J14 #20 to #23 100 Ω ±20 Ω
J14 #21 to #22 100 Ω ±20 Ω
J14 #21 to #23 100 Ω ±20 Ω
2. If the readings are not within the above tolerances,
replace the RTD probe (PN 71130).
Product flow does
not register on LCR
600 display.
1. Pulser shaft is not
turning with product flow.
1. Manually spin the pulser shaft and monitor the LCR 600
display.
2. Pulser failure. 2. If the LCR 600 display counter increments, this may
indicate a mechanical problem. Contact your local
Liquid Controls distributor or the Liquid Controls service
department for assistance.
3. If the LCR 600 display counter does not increment, see
“Pulser Failure” in the following troubleshooting section.
