Trouble Shooting
NOTICE
DANGER
It may be necessary to break Weights & Measure seals to
perform certain troubleshooting steps in this guide. Con-
tact your supervisor or local Weights & Measures authori-
ties for information before breaking any seals.
Serious Injury or Death may Result – Fire, Explosion, and
Electrical Shock Hazard.
Only trained and authorized personnel should perform
troubleshooting. Use extreme caution when troubleshoot-
ing and taking all electrical measurements. Be sure that
equipment is in a well ventilated area and that hazardous
or flammable vapors are not and will not be present dur-
ing testing. If equipment is located in a hazardous envi-
ronment, it may be necessary to remove the equipment
and perform troubleshooting in a safe area.
Trouble Shooting
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 deliver.
NOTE: This procedure will not work for an empty or dry hose. If more than 1 gallon or 5
Liters of liquid is required to pack the hose, a delivery ticket must be printed.
To pack the hose at the start of a delivery:
Press the Start Button, this energizes the solenoids. Allow the pump to pack the hose.
TCS 3000 Trouble Shooting Guide
The TCS3000 troubleshooting guide covers most common problem situations. Call your Total Controls Service Center
for any problems that are not covered in this guide.
Trouble Shooting Guidelines:
1) Before attempting to troubleshoot the TCS 3000 system, become familiar with the operation and set-up of the specific
installation.
2) Make sure all electrical connections are secure and tight.
3) Make sure all terminal blocks are firmly connected.
4) ALWAYS use a good digital multimeter. Voltage levels are critical to proper system operation. Use an accurate,
reliable multimeter to test for proper voltages at the start of any service procedure. Voltage requirements are listed
under each component.
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 TCS 3000.
5) If an error occurs during a delivery, the message will appear on the Display and print on the delivery ticket. The
delivery ticket will print an error message that can be useful in troubleshooting. This ticket will automatically print.
Examine the prover ticket to make sure all set-up fields are accurate, e.g. pulses per unit volume, temperature
coefficient, and base temperature.
6) NEVER remove a terminal block or jumper with the power on.
7) NEVER install a terminal block or jumper with the power on.
