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 20 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.
2. 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. The unit will then start and run it’s 20 minute
exercise cycle.
For example, if you press the “Set Exercise” button on
Sunday morning at 10:00 AM, the unit will run an immediate
exercise cycle and an exercise cycle every following Sunday
at 10:00 AM (+/- 1/2 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 12 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.
Maintenance
Servicing the System
To service the residential generator system:
1. Remove 15 Amp fuse from control panel.
2, Set control panel system switch to
OFF .
3. Set the generator’s main circuit breaker to its
OFF
position.
4. Utility voltage is present. Disconnect power before
servicing by removing the two fuses from the
transfer switch.
Fault Detection System
The generator may have to run for long periods of time
with no operator present. For that reason, the system is
equipped with sensors that automatically shut down the
generator in the event of potentially damaging conditions,
such as low oil pressure, high temperature, over speed, and
other conditions.
The generator’s control panel has a digital display that shows
fault codes, like “FC_1”. The table below lists the detected
fault, the fault code as displayed on the control panel, and
the number of LED flashes (also described as ‘blinks’) seen
on the remote LED indicator.
Fault Description Fault Codes LED Flashes
Low battery voltage FC_1 1
Low oil pressure FC_2 2
Low voltage FC_3 3
Engine fails to start FC_4 4
Low frequency FC_5 5
Engine overspeed FC_6 6
High temperature FC_7 7
Transfer switch fault FC_8 8
The remote LED indicator is installed at a convenient inside
location. The LED will remain lit when the generator is in
AUTO. Should a system fault be detected, the LED will turn
on and off in a series of blinks that identify the problem. The
blink pattern is repeated with a brief pause between each
series of blinks.
Reset Fault Detection System
The operator must reset the fault detection system each
time it activates. To do so, place the control panel System
switch in the OFF position for 5 seconds or more. Remedy
the fault condition, then return the residential generator to
service by placing the system switch in the AUTO position,
installing the 15 Amp fuse, and resetting the exercise timer.
