Trouble Shooting
PROBLEM
PROBABLE CAUSE SOLUTION
Valve will not
open
Solenoids are inac-
tive or inoperative.
Foreign debris in sys-
tem
1. Insert a delivery ticket into the Epson printer and start a delivery.
2. Start a delivery and listen for the audible clicking sound from the solenoids.
3. If there is NO audible click form the solenoid, check the voltage to Pin +
and 0 V of terminal block Solenoid 1. While the TCS 3000 is still in deliv-
ery, use a reliable multimeter to measure the following DC voltages on the
circuit board. Use 0 pin as a ground or frame ground.
4. If there is an audible click from the solenoid (but still no flow), this may be
an indication of a mechanical problem with the main valve or its associate
components. Contact your TCS3000 Service Center.
TERMINAL SOLENOID 1 for 2 VOLTAGE
9.0 VDC with plug remove VDC
2..0 VDC with solenoid connect
12.0 VDC with the solenoid energized
5. If the above voltages are correct, this may be an indication of a problem
with the valve or its associated components. Contact you TCS 3000 Ser-
vice Center for assistance.
6. If the above voltage are NOT correct, replace the following components
with known working units until the problem is resolved: Solenoids
7. TCS 3000 Circuit Boards
Product has
wrong Name
The Register was
never calibrated or
had the name
changed in W&M
Settings.
Go into prover and calibrate the product or change the Name.
Valve doesn’t
shut off
Valve was never set
up or calibrated
Select the product and calibrated the valve for zero shutoff.
Display is read-
ing in reverse
Channel A and B are
wired backwards
Switch wiring between Channel A and B
Daisy chain
communication
is not working
Network Address of
registers are not in
proper sequence
Host and Client Ad-
dresses are not in
proper sequence
1. Check the RX and TX wiring between registers.
2. Make sure the printer is wired to the primary HOST register.
3. Check the Device Addresses of each register, with the primary HOST as 1
and CLIENTS from 2 to 8.
4. Make sure the primary HOST register has the Client Address Range set to
communicate with all the TCS 3000 registers in the daisy chain.
Totalizers are
incorrect
Product vs. System
Totalizer
Ticket is configured
to show Product To-
talizer instead of Sys-
tem Totalizer
Net vs. Gross
Totalizer
1. The Product Totalizer was not reset when the System Totalizer was reset
to zero.
2. The ticket is configured to print the Product Totalizer instead of the System
Totalizer, or visa-versa.
3. The ticket is configured to print the Net Compensated Totalizer instead of
the Gross Uncompensated Totalizer, or visa-versa.
Cant begin a
delivery be-
cause the
screen reads
“Delivery Not
Completed”
Last delivery had the
printer enabled, but
the ticket had not
printed.
The delivery ticket must be printed when the printer is communicating with the
TCS 3000. To move on without the printer, either disable the printer or have
the Select Printer changed to None under Printer Settings. You will be able to
Re-print Tickets under the Select Function.
