Auxiliary shutdown switches are not intended to be a pri-
mary means to shut down generator under normal oper-
ating  conditions.  Accidental  activation  of  an  auxiliary
shutdown  switch  will  prevent  generator  from  operating
during a power outage.
Checking Automatic Operation
Proceed as follows to check system for correct automatic
operation:
1. Verify generator is in OFF mode. Red LED above
OFF on control panel illuminates to verify system is
OFF.
2. Install front cover over transfer switch.
3. Turn  on  utility  power  supply  to  transfer  switch,
using  the  means  provided  (such  as  a  utility  main
line circuit breaker).
NOTE: Transfer switch will transfer to utility position.
4. Set  MLCB  on  generator  control  panel  ON
(CLOSED). 
5. Verify both auxiliary shutdown switches are ON (I).
6. Press  AUTO  on  control  panel.  System  is  now
ready for automatic operation.
7. Turn off utility power supply to transfer switch.
With generator ready for automatic operation, engine will
crank  and  start  when  utility  source  power  is  turned  off
after  a  10  second  delay  (factory  default  setting).  After
starting, transfer switch connects load circuits to standby
side. Allow  system  to  operate  through  entire  automatic
sequence of operation.
With generator running and loads powered by generator
AC output, turn on utility power supply to transfer switch.
System  transfers  back  to  utility  position  and  then  runs
through cool down cycle and shuts down.
Installation Summary
1. Verify installation has been performed correctly as
outlined by  the  manufacturer and  that  it  meets all
applicable laws and codes.
2. Test and verify correct operation of the system as
outlined in the appropriate installation and owner’s
manuals.
3. Educate  end-user  on  correct  operation,  mainte-
nance, and service call procedures. 
Shutting Generator Down While 
Under Load or During a Utility Outage

Shutdowns may be required during utility outages to
perform routine maintenance or to conserve fuel.
To turn generator OFF:
1. Set main utility disconnect to OFF (OPEN).
2. Set  generator  MLCB  (generator  disconnect)  to

3. Allow  generator  to  run  for  cool-down  for  approxi-
mately one minute.
4. Set generator to OFF at the controller.
5. Remove 7.5A fuse from controller.
To turn generator back ON:
1. Install 7.5A fuse in controller.
2. Verify  generator  MLCB  (generator  disconnect)  is
OFF (OPEN).
3. Set generator to AUTO mode at the controller.
4. Generator will start and run. Allow generator to run
and warm up for a few minutes.
5. Set  MLCB  (generator  disconnect)  to  ON
(CLOSED).
