Engine Controller Operation
Auto Mode Operation
When the controller receives an automatic start signal (across pins 10 and 11), the glow plug
output turns on (if switch 3=On) and the delay begins. When the glow plug delay expires, the fuel
and crank outputs turn on. When the engine starts, the glow plug output is turned off. At this
time, the Shutdown Lockout and the Warm−up Time Delay (if selected) will begin, and the starter
is disengaged.
The Shutdown Lockout Delay causes the controller to ignore the Oil Pressure, Engine
Temperature and Spare Shutdown inputs at engine start up. If the engine false starts before the
delay expires, the engine will re−crank after a fixed delay (35 seconds), to let the engine stop
moving before engaging the starter. When the delay expires, the Loss of Speed Signal shutdown
is armed. Loss of Speed Signal occurs when both Overcrank and Overspeed LED's turn on if the
speed drops below the crank disconnect set point.
After the Warm−up delay, the "At Load" output turns on (if selected).
The spare shutdown is armed immediately. There is no LED annunciation for either of the spare
shutdowns. They are reset by moving the Manual−Stop−Auto switch to Stop position
(disconnecting power) and back to Auto or Manual positions. If engine speed exceeds the
Overspeed set point (R1), the controller will turn off the fuel valve, turn on the Overspeed LED,
and lockout the engine from any further start attempts.
If a Low Oil Pressure or High Engine Temperature shutdown occurs while the engine is running,
the controller will turn off the fuel valve, turn on the appropriate LED and lockout the engine from
any further start attempts.
When the controller receives an automatic stop signal (remote start contacts open), the "At
Load" output turns off, and the Cooldown time delay (if switch 3=Off) will begin. When this delay
expires, the controller will turn off the fuel valve to stop the engine.
Manual Mode Operation
When the controller receives an manual start signal (pin 10) an automatic start signal is
simulated. Controller operation is the same as for Auto Mode all delays and shutdown conditions
are the same. Unless a shutdown occurs, the engine will continue to run until the controller
receives a manual stop command (by moving the Manual−Stop−Auto switch to Stop position).
Manual stop operation is the same as automatic stop operation.
