Setting Exercise Timer - Rheem GEN10AD Manual Del Operario

utility Voltage Pickup Sensor
This sensor monitors utility power supply voltage. When that
voltage is restored above 80 percent of the nominal source
voltage, a time delay starts timing and the engine will go to
engine cool-down.
Engine Cool-down Timer
• When the load is transferred back to the utility power
source, the engine cool-down timer starts timing.
• The timer will run for about one minute, then the
generator will stop.
• Minimum engine run time is 5 minutes.
To select automatic operation, do the following:
1. Confirm 15 Amp fuse is installed in control panel.
. Set service disconnect or main distribution panel circuit
breaker that sends utility voltage to the transfer switch
to ON.
3. Set the generator's main circuit breaker to its
ON position.
4. Set the system switch to AUTO.
CAuTION
With the system switch set to AUTO, the
engine may crank and start at any time
without warning.
• To prevent possible injury that may be caused by such
sudden starts, always set the system switch to OFF if
performing maintenance on the system.
• Remove the 15 Amp fuse before working on or around
the generator or transfer switch.
Checking Automatic Operation
To check the system for proper automatic operation, proceed
as follows:
1. Turn OFF the service disconnect or main distribution
panel circuit breaker sending power to the automatic
transfer switch.
The engine will crank and start when the utility voltage
drops out and the sensor has timed out. Let the system
go through its entire automatic operation sequence.
. With the generator supplying voltage its loads, turn ON
the service disconnect or main distribution panel circuit
breaker that supplies utility power to the automatic
transfer switch.

3. The automatic transfer switch will transfer loads back
to the utility power after 5 minute minimum run time
and utility is restored.
4. The generator will run for an additional one minute for
engine cool down, then shut down.
NOTE: If utility is restored and generator does not shut
down after 10 minutes, set system switch to OFF and
contact your installer or local service center.
This completes the test procedures for automatic operation.
The residential generator will now start automatically
when utility power is lost and will supply power to the
transfer switch.

Setting Exercise Timer

The residential generator is equipped with an exercise
timer that will start and exercise the system once every
seven days. During this exercise period, the unit runs for
approximately 0 minutes and then shuts down. Electrical
load transfer DOES NOT occur during the exercise cycle
(unless an utility power outage occurs).
A button on the control panel is labeled "Set Exercise"
(see System Control Panel). The specific day and the
specific time of day this button is pressed is programmed
into the control board memory. This date and time is then
used to automatically initiate the system exercise cycle. The
"SET EXERCISE" legend on the control panel will flash until
the set exercise cycle is set.
To perform the Set Exercise procedure:
1. Choose the day and time you want your residential
generator to exercise.
. On that day and time, press and hold down the
"Set Exercise" button for three seconds.
NOTE: "SET EXERCISE" will flash until the button is
pressed for three seconds, then "SET EXERCISE" will
illuminate for 5 seconds, and finally turn off.
3. Seven days later the unit will then start and run it's
0 minute exercise cycle.
For example, if you press the "Set Exercise" button on
Sunday morning at 10:00 AM, the unit will run an exercise
cycle the following Sunday at 10:00 AM (+/- 1/ hour).
NOTE: "Set Exercise" will only work if the unit is in
the AUTO mode and this exact procedure is followed.
The exerciser will need to be re-set if the 15 Amp fuse
is removed or changed, or if the 1 Volt DC battery is
disconnected.
If you want to change the day and time the unit exercises,
simply perform the "Set Exercise" procedure at the exact
weekday and time you want it to take place.
