Operation
Set the Controller Clock
The schedule runs based on the time set in the controller
clock. Proceed as follows to set the controller clock
before setting the schedule:
1. Navigate to the maintenance group and press ► to
access it.
2. Press ► to select the time section.
3. Set the time and date to the correct local time.
Set the Schedule
NOTE: The controller must be in AUTO mode to run at
the programmed time. Use a trickle or solar battery
charger to prevent the controller from draining the battery
while in AUTO mode.
1. Access the scheduler group by pressing the ►
button.
NOTE: The scheduler group consists of the scheduler
options and scheduler setup sections. Each section can
be accessed and exited using the ► and ◄ buttons.
2. Access the scheduler options section. Within this
section, the scheduler can be enabled, run mode
selected, and load mode selected.
3. Access the scheduler setup section. In this section,
each schedule entry can be modified by pressing
the  button to select the item, and the ▲ and ▼
buttons to define them.
NOTE: If setting up a daily scheduled run, select Weekly
Run Mode, then set start time and duration for each day
(seven schedule entries total). This will repeat the seven
day schedule as long as the unit is in AUTO mode.
Setting Up a Daily Scheduled Run
1. Enable the scheduler.
2. Set RUN mode to Weekly.
3. Set load to preferred method.
4. Set the start time and duration for seven days
(Monday–Sunday).
5. Set the controller to AUTO mode.
Set the Unit to AUTO Mode
From any operator or maintenance screen, press and
hold the AUTO or MANUAL mode ( ) button for five
seconds, or until AUTO mode is displayed at the top of
the screen.
NOTE: If any of the scheduled time slots are currently
active, the controller will begin the starting sequence and
start the unit, provided there are no shutdown conditions
present.
Shutting Down the Unit
Prior to shutting down the unit, check with personnel
using power supplied by the generator and let them know
the power is going to be turned off. Verify the power shut
down will not create any hazards by accidentally turning
off equipment that needs to be kept on (pumps,
compressors, lights, etc.).
1. Remove all loads from the generator by opening all
circuit breakers (turn OFF (O)).
2. Allow engine to run for approximately five minutes
to allow it to cool down.
3. Press the red engine STOP (O) button on the
controller. This will result in the generator going
into the shutdown cycle and starting a 15 second
shutdown timer. If the unit does not shut down
within 15 seconds, a stop fail alarm will be
displayed on the display screen.
4. After the unit shuts down, wait two minutes after
engine shutdown for controller actuated actions to
complete and then set the control power switch to
OFF (O).
NOTE: Turning off the control panel before the controller
finishes updating could cause a loss of data.
NOTE: For extended storage time, disconnect the
battery. See the engine operator’s manual for extended
storage requirements.
