Generator  Contactor  Relay  Output: 

Generator contactor output is used  for energizing the 

generator contactor to transfer load to the generator. It outputs R phase of the generator from 
its normally open terminal. 
 

Alarm Relay Output: 

Alarm output is used for indicating any failure event. It outputs battery 

+ supply voltage. 
 

Fuel/Stop  Solenoid  Relay  Output

:  Used  for  energizing  the  fuel/stop  solenoid  relay  of  the 

generator. It outputs b supply voltage. It can be configured as fuel or stop solenoid by 
adjusting P23 number of parameter. 
 

Starter  Relay  Output:

  Used  for  energizing  the  starter  motor  relay.  It  outputs  battery  + 

supply voltage. 
 

Auxiliary  Relay  Output: 

Auxiliary  output  can  be  configured  as  preheat,  auto  ready  and 

motor running output. It outputs b supply voltage. 
 
 

FAILURES 

 

In  the  event  of  a  failure,  relevant  fault  LEDs  identify  the  problem  and  activate  the  alarm 
output  to  sound  the  external  horn.  If  the  failure  is  a  shutdown  failure,  the  module  will  de-
energize  the  fuel  solenoid  and  stop  the  generator.  If  it  is  a  warning  failure,  the  unit  will 
indicate the fault but continue to operate. By pressing the off button the failure can be reset. 
The alarm condition must be reset to enable the module operating again.

 

 
 
 
 

 

Overspeed/Underspeed  Failure  (shutdown):

  If  the  frequency  of  the  generator 

output  exceeds  or  falls  below  the  pre-configured  alarm  level  a  shutdown  is 
initiated. The relevant failure LED will illuminate and alarm output is energized.

 

 

High/Low  Voltage  Failure  (shutdown):

  If  the  voltage  of  the  generator  output 

exceeds or falls below the pre-configured alarm level a shutdown is initiated. The 
relevant failure LED will illuminate and alarm output is energized

 

 

High Engine Temperature Switch (shutdown):

 If the module detects a negative 

signal  from  the  high  engine  temperature  switch  (close  circuit)  while operating,  a 
shutdown is initiated The relevant failure LED will illuminate and alarm output is 
energized. 

 

Over  Current  Switch  (shutdown): 

If the  module detects a negative signal  from 

the over current switch (close circuit) while operating, a shutdown is initiated the 
relevant failure LED will illuminate and alarm output is energized.

 

 

Start/Stop  Failure  (shutdown):

  If  the  engine  does  not  fire  after  the  pre-set 

number of attempts  has  been  made a start failure shutdown will  be  initiated. The 
start/stop failure LED will  illuminate. And  if the  start signal of the generator has 
still existed while fuel solenoid de-energized, the module will indicate stop failure. 
The  start/stop  failure  LED  will  illuminate  with  the  active  signal’s  failure  LED 
which must be inactive.

 

 

Low Oil Pressure Switch (shutdown

): If the module detects a loss of signal from 

the oil pressure sender (open circuit) a shutdown is initiated. This parameter can be 
disabled by configuring P34 number of parameter. Switch position (NC, NO) can 
also  be  adjusted  by  configuring  P35  number  of  parameter.  The  relevant  failure
