OPERATION
AUTOMATIC OPERATION
To select automatic operation, do the following:
1.Set the service disconnect or main distribution panel circuit breaker that sends utility voltage to the transfer switch to ON.
2.Set the generator’s main circuit breaker to its ON position.
3.Set the system switch to AUTO.
Servicing the System
To service system:
1.Set the system switch to OFF.
2.Set the generator’s main circuit breaker to its OFF position.
3.Utility voltage is present. Disconnect power before servicing by removing the two 2 Amp fuses from the transfer switch.
CAUTION
With the switch set to AUTO, the engine may crank and start at any time without warning. Such automatic starting normally occurs when utility source voltage drops below a preset level or during the normal exercise cycle.
•To prevent possible injury that might be caused by such sudden starts, always set the system switch to OFF.
•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.
2.With the generator output supplying 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 Home Generator System will now start automatically when utility power is lost and will supply power to the transfer switch.
Setting Exercise Timer
The Home Generator System 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 20 minutes and then shuts down. Electrical load transfer DOES NOT occur during the exercise cycle (unless an utility power outage occurs).
A switch on the control panel is labeled “Set Exercise” (see page 10).The specific day and the specific time of day this switch is pressed is programmed into the control board memory.This date and time is then used to automatically initiate the system exercise cycle.The LED on the control panel will flash until the set exercise is set.
To perform the Set Exercise procedure:
1.Choose the day and time you want your Home Generator System to exercise.
2.On that day and time, press and hold down the “Set Exercise” switch for three seconds.
NOTE: The LED will flash until the switch is pressed for three seconds, then the LED will illuminate for 5 seconds and turn off.
For example, if you press the “Set Exercise” switch on Sunday morning at 10:00 AM, the unit will run an exercise cycle the following Sunday at 10:00 AM (+/- 1/2 hour).
NOTE: “Set Exercise” will only work if the unit is in the Automatic mode and this exact procedure is followed.The exerciser will need to be
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.
