SOLUTION
“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.

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 ow does
not register on LCR
600 display.
1. Pulser shaft is not
turning with product ow.
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.
