ENGINE MANAGEMENT
The engine management module is very similar to
that used in the manufacturer's other products. It
controls engine cranking, engine starting, engine
running and engine stopping. These functions are
performed to a set of “rules” that can be customized
via parameters from GenLink. In turn, the module
needs to know certain things about the engine which
it expects to be programmed in from GenLink.
GENERATOR PARAMETERS
Engine Flywheel Teeth — Number of flywheel teeth
or pulses per revolution for RPM input. RPM 1 is
used for the engine controllers.
CT Ratio/Generator — Current Transformer ratio
for the generator. This value is the result from
reducing the CT ratio. E.G. If the CT ratio is
100 amps to 5 amps, the resulting value is 20.
Normally, the CT ratio will be x amps to 1 amp on
H-100 Control Panels.
Generator Phase Configuration — Select either
single-phase or three-phase configuration depend-
ing on how the unit is supplied.
60 Hertz RPM — The engine RPM needed to supply
60 Hertz power.
Quiet-Test
®
RPM — The engine RPM used when
running Quiet-Test
®
.
ENGINE SETTINGS
All of the following times are in seconds:
Preheat Time — The time preheat is applied for
before cranking if enabled.
Start Detection RPM — The Engine must reach this
RPM before disengaging the starter.
Crank Time — The maximum time in seconds that
each crank will last
Alarm Hold-off Time — The time after starting at
which the hold-off alarms become enabled.
Engine Warmup Time — The engine will run for
at least this time before issuing the “Accept load”
signal.
Target Frequency — The target generator frequency
(Hz).
Target Voltage — The target generator voltage
(RMS).

Preheat Enable — The following four options are
selectable (only for Diesel):
- Preheat disabled.
- Preheat during cranking.
- Preheat before and during cranking.
- Preheat before and during cranking and until
load ready.
The Preheat output pin shares its function with the
Air/Fuel Solenoid output. You must choose one of
the two functions as follows:
- To select Air/Fuel - set the “Diesel” parameter on
the governor settings page to “No”. Set Preheat to
“Disabled”
- To select Preheat - set the “Diesel Y/N” param-
eter on the governor settings page to “Yes”. Set
Preheat to one of the enable selections.
Engine Cooldown Time — The generator will run
for at least this time after remote start becomes
inactive.
Pause Between Cranks Time — The time between
each successive crank operation.
Number of Start Attempts — The maximum num-
ber of times the engine will attempt to start (crank)
before faulting out with overcrank.
Load Accept Frequency — The generator must
reach this frequency before issuing the “Accept
load” signal.
Load Accept Voltage — The generator must reach
this voltage before issuing the “Accept load” sig-
nal.
