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 = 8:30 A,
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 to at least 3 days (Set Gen Exercise Days = 3). On Day 1, the genera-
tor 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 counting 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 accumulated since the
generator last ran – the Days Since Run timer displays 2 days. On Day 4
(3rd day since the generator was manually started) at 2:00PM, 72 hours (or
3 days) have now accumulated since the generator 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.
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.
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.
damage your generator. Also, the fuel in gasoline-powered generators can
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.
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 gen automatically starts
and runs for 1 hour (Set Gen Exercise Run Time = 1.0 Hrs).
