Generac Power Systems H-100 사용자 설명서

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.

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

®

.

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.
