TGA Timers

Solid State DC Voltage

Timing Mode | Delay on Make

Category | Timer with Relay

Series | TGA

TGA is a delay timer used in engine starting circuits to bypass ground-connected sensors during cranking and initial run.

The 10 amp internal relay has normally-open and normally-closed contacts, internally connected to the battery connection (b).

The relay contacts can disconnect the ignition coil, or various types of fuel valves during asensed fault, or energize a shut-down solenoid if one is used.

A sense terminal (s) is used to connect to ground-connected fault sensors.

Timing Mode

Operation 1: With terminal G open, timing begins when sensor contact is closed. After time out, if sensor stays closed, the relay transfers. Opening sensor contact will reset timer and drop out relay.

Operation 2: With sensor open, timing begins when G terminal goes to ground. If sensor closes during timing, the relay will transfer. If sensor stays open after timing ends, the relay will not transfer until the sensor closes.
