Checking Automatic Operation; Installation Summary; Shutting Generator Down While Under Load Or During A Utility Outage - Generac Power Systems D3.4L G16 Extended Tank Installation Manuallines

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.
