** The status relay is the uP watchdog output. This relay is normally energised, and the switch is
closed after power-up. If the uP fails or the power is lost, the relay will de-energize and the
switch will open. If the unit fails to start up at power-up, then the relay switch will remain open.
The binary output functions are configurable via the TPS 300 software and can be configured to
cover the following functions:
-
Alarm/limit
-
Engine running
-
Horn
-
Idle speed
-
Not used
-
Start prepare
-
Run coil
-
Starter
-
Stop coil
-
External heater
-
Stop coil (not acc. in start seq.)
-
Fuel pump
It is possible to choose run coil on one relay and stop coil on another, thus supporting engines with
double systems.
