begin to break down into gums and varnishes that clog the fuel system. Fuel
varnishing results in hard starting and surging—a surging generator may not
settle at a stable operating speed. Always check with your generator’s manu-
facturer to determine how to properly exercise your generator. Generally,
it is recommended that you run the generator every month for two hours
under at least half the rated load. For example, with a 5,000 watt generator,
turn on a load(s) that is about 2,500 watts, and let it run continuously for
two hours. It is always best to run the generator for longer periods of time
rather than for multiple short periods.
How does this Gen Exercise feature work? The Gen Exercise feature
allows the generator to autostart at a pre-selected time whenever it has not
run for a set number of days.
Once the Gen Exercise feature is enabled (by setting how many days to
wait before exercising the gen under Set Gen Exercise Days), the generator
will start and begin exercising only after two conditions are met. First, the
generator must not have run for a set number of days (i.e., the Days Since
Run timer value must be equal to or greater than the Gen Exercise Days set-
ting). Second, the generator’s exercise time of day (i.e., Exercise Run Hour/
Minute/AM-PM settings) must occur.
Info: When the generator starts and runs based on the gen exercise
criteria, the generator power passes thru the inverter to the inverter
loads — if the inverter is enabled to accept AC power on its input—
and also charges the inverter batteries (if the charger is enabled).
Info: The Gen Exercise feature identifi es the number of days since
the generator has last run by using the Days Since Run timer which
is shown under the METER: 03E Since Gen Run display.
Example of a Gen Exercise Scenario:
Under SETUP: 04H Gen Exercise Menu, set to:
Set Gen Exercise Days = 3,
Set Gen Exercise Run Hour, Minute and AM-PM = 8:30A,
Set Gen Exercise Run Time = 1.0 Hrs
Under CTRL: 03 Gen Control, set to AUTO.
First required condition: The Days Since Run timer must have accumu-
lated up to at least three days (Set Gen Exercise Days = 3). On Day 1,
the generator was manually started and stopped at 2:00PM. The stop time
(2:00 PM) is the starting point for the Days Since Run timer to begin count-
ing days—the Days Since Run timer displays “0 days”. On Day 2 at 2:00
PM, 24 hours have accumulated since the generator has last run—the Days
Since Run timer displays “1 day”. On Day 3 at 2:00 PM, 48 hours have ac-
cumulated since the generator last ran—the Days Since Run timer displays
“2 days”. On Day 4 (third day since the generator was manually started) at
2:00PM, 72 hours (or three days) have now accumulated since the genera-
tor has last run—the Days Since Run timer now displays “3 days”. The fi rst
required condition—which is how many days must pass before the generator
hasn’t run—has been met.
Second required condition: The remote clock must now go to 8:30 AM
(Set Gen Exercise Run Hour, Minute, and AM-PM = 8:30A) before the gen-
erator can autostart. On Day 5 at 8:30AM (Days Since Run timer displays “3
days”), the second required condition is met and the generator automatically
starts and runs for one hour (Set Gen Exercise Run Time = 1.0 Hrs).
