Engine Controller Description

When a fault circuit is programmed as a SHUTDOWN, the engine will immediately stop when the
fault is activated. A specific shutdown fault can be programmed with a definite time transient
delay period that must expire before the shutdown is activated. The stop sequence will cause the
controllers RUN output to be immediately terminated which will cause the engine to stop.

Description
Output − Drives a pilot relay to Open/Close the fuel valve.
Output − Drives a pilot relay to Open/Close the Starter Relay to crank engine.
Output − Drives a pilot relay to Open/Close the Glow Plug relay.
Output − On during Overcrank shutdown (engine fails to start after the number of crank cycles).
Output − On during Overspeed shutdown (engine's speed has exceeded the overspeed setpoint).
Output − On during Low Oil Pressure shutdown
Output − On during High Water Temperature shutdown
Output − On during normal engine operation
Input − Closed to ground will turn on all LED outputs.
Input − Closed to B+ will initiate a crank cycle (manual mode)
Input − Closed to B+ will initiate a crank cycle (from a remote source, shorts pins 10 and 11 together).
Ground. Battery (−).
Input − Speed input that monitors engine RPM from engine mounted magnetic pickup. (Delayed for engine start).
Input − Oil Pressure input from sender unit that monitors oil pressure. (Delayed for engine start).
Input − Water Temperature input from sender unit that monitors water temperature. (Delayed for engine start).
Input − Extra input for shutdown fault identification and protection. (Delayed for engine start).
Input − Extra input for shutdown fault identification and protection. (Not delayed for engine start)
Input − Battery Voltage (B+).
