Power On Time Relay Installation - TCS 3000 Installation Manual

Power On Timing Relay
When installing the TCS 3000 register on delivery tank trucks, it is recommended to use a timing relay for safe startup of the TCS
3000 registration. Install the TCS 300289 Power On Time Relay from the Accessory Ignition (ACC) to the TCS 3000 register for a
selectable time (Seconds) open of power. This will allow the clean power to the TCS 3000 register during its boot up cycle and limit
exposure to any significant current draw from charging glow plugs or a low power battery startup.
Installation Procedure:
1) Wire GND to the Negative side of the Battery. NOTE: a minimum of a 18 gauge wire should be used.
2) Wire ACC (+) and (C) ACC Positive (on the relay), then jumper ACC Positive to the truck ACC (Ignition).
3) Wire N.O. to the (Positive) side of the Terminal Board in the TCS 3000 register.
4) Adjust the Time interval with a small Philips screw driver. Recommended minimum value is 45 seconds.
NOTE: If your wiring a Printer, it should be wired to the N.O. also. This will allow the printer to power up at the same time.
