PROBLEM
PROBABLE CAUSE SOLUTION
Power Fail-
ure appears
on the deliv-
ery ticket
Power to the TCS
3000 interrupted dur-
ing delivery.
Static Discharge
1. Check accessory power cable for damage. Ensure that the power, common
and ground wires on power connector are secure. Located on the right hand
corner of the terminal board
2. Turn on all truck accessories (headlamps, 2 way radio, heater, etc.). Engage
the hose reel and monitor the DV voltage at ## using terminal ## as positive
and terminal ## as ground. If the voltage drops below +10VDC, the truck
electrical system may not be adequate to handle the current load for the TCS
3000. It may be necessary to upgrade the electrical system to accommodate
the 3-amp TCS 3000 current requirements.
3. Verify proper grounding of the TCS 3000. Refer to the TCS 3000 Installation
Manual for proper grounding procedures.

Low voltage to the
Epson Printer
1. Check the battery voltage for a minimum of +12.6VDC.
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.
No power

Epson Print-
er
No power to the Ep-
son 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 to ensure that it is seated properly. If the prob-
lem persists, replace the power cable followed by the Epson printer.
“Temperatur
e Error” ap-
pears on the
TCS 3000
display
Open or shorted cir-
cuit between RTD
probe and the TCS
3000
1. Check the RTD Probe and terminal block for continuity.
2. Remove terminal block Temp Probe from the circuit board. On the terminal
block, measure and record the resistance between the following pins:
PIN READING
Red to White 100 Ω ±20?
3. If the readings are not within the above tolerances, replace the RTD
probe.
Product flow
does not reg-
ister on TCS
3000
Pulser shaft is not
turning with product
flow. Pulse Failure
1. Manually spin the pulser shaft and monitor the TCS 3000 display.
2. If the TCS 3000 displays counter increments, this may indicate a mechanical
problem. Contact your TCS 3000 Service Center for assistance.
3. If the TCS 3000 display counter does not increment, see Pulser Failure.
Pulser Fail-
ure, register

Missing pulse
counts.
Excessive reversals
Note: Pulser faults
generally occur in a
high vibration envi-
ronment. TCS is not
responsible for puls-
er failures caused by
excessive vibration.
1. Check the pulser output.
2. Open the TCS 3000 cover by loosening the two bolts that hold the cover
closed. Using a reliable multimeter, measure the following DC voltages on
terminal block is connected to the circuit board. Use terminal as ground refer-
ence.
3. TERMINAL PULSER VOLTAGE
+0 VDC
+5 VDC
+3.74 TO 0 VDC TAHA1 WHILE SPININING
+0 TO 3.74 VDC TAHB1 WHILE SPINNING
4 If the following voltages are observed, check for loose pulser wiring connec-
tions. If no loose connections are found, replace the encoder.
5 Insert a ticket into the Epson printer. Begin a delivery. With product flowing
through the meter, measure the following DC voltages on the terminal block.
6 TERMINAL PULSER VOLTAGE
+0 VDC
+5 VDC
+3.74 to 0 VDC TAHA1 WHILE SPINNING
+0 to 3.74 VDC TAHB1 WHILE SPINNING
