3.8 Operating Modes
The generator set's PowerCommand
®
control has Manual Run, Off, and Auto
operating modes that are available from the operator panel.
Off Mode
When in the Off mode, the control does not allow the generator set to start.
If the generator set is running in either Manual Run or Auto mode and the Off button
is pressed, the control immediately stops the generator set, and the control
transitions to the Off mode.
Pressing the Off mode button resets all active faults.
Manual Run Mode
When in Manual Run mode, the generator set starts and continues to run until the
control is put into the Off mode. While in Manual Run mode, the remote start signal
is ignored.
Auto Mode
When in Auto mode, the control allows the generator set to be started at any time
with a remote signal only. When a remote start signal is received, the generator set
starts after a time delay start is completed (default delay is zero seconds).
When all remote start signals are removed, the control performs a normal shutdown
sequence which includes a time delay stop (default delay is five minutes).
If the generator set is running in Auto mode and the Off button is pressed, the
control immediately stops the generator set and the control transitions to the Off
mode.

starts or stops when changing modes.
1. Before proceeding to change the mode, make sure that it is safe to do so.
