Control Module
The control module operates and monitors multiple
functions such as warning lighting, seat delay, audible
buzzer, PTO interlock and start timer.
Warning lights on the module include battery voltage,
low oil pressure, high coolant temp and glow plugs.
On initial start up, all lights will illuminate for one
second and the buzzer will chirp one time.
Battery Voltage
The battery light will illuminate constant if the battery
voltage drops below 12V and will flash if voltage
jumps above 15V.
Oil Pressure
When the ignition switch is turned to ACC or RUN,
the oil pressure light will illuminate until the engine is
started.
After thirty seconds, the buzzer will sound and the
ignition switch will need to be turned off and back on
before the PTO will function. If the oil pressure drops
to an unsafe level during operation, the buzzer will
sound, the PTO will disengage and the ignition switch
will need to be turned off and back on before the PTO
will function.
Coolant Temperature
If the coolant temperature reaches an unsafe level, the
light will illuminate for 30 seconds. After 30 seconds,
the buzzer will sound and the PTO will disengage and
the ignition switch will need to be turned off and back
on before the PTO will function.
Glow Plug
Depending on the ambient temperature, the glow plug
light may also illuminate indicating that a pre-glow is
required. After the engine is started, the glow light will
remain lit for five seconds as an after glow.
Above 50° F (10°C), no pre-glow is required and the
light will illuminate for one second
Above 23° F (-5°C), but below 50° F (10°C), a
five second pre-glow is required and the light will
illuminate for five seconds
Below 23° F (-5°C), a ten second pre-glow is required,
and the light will illuminate for ten seconds.
Once the engine is started, these lights will remain off
unless there is low oil pressure, high coolant temp,
or the alternator quits charging causing low battery
voltage or battery voltage jumps to an unsafe level.
