SETUP: 04H Gen Exercise Menu
This menu allows the generator to run (or “exercise”) after it has not been operated for a period
of time. The generator is automatically started at a pre-selected time whenever it exceeds a set
number of days without running.
Once the start command is initiated, the generator starts and runs to help it remain operational
and to allow the generator’s starting battery to be charged.
Info: The ME-ARTR contains a real time clock that must be set for proper operation of
the SETUP: 04H Gen Exercise menu feature.
• Set Gen Exercise ( Start Gen Days) – This menu sets the maximum number of days the
generator is allowed to sit without running. If the generator has not run in this number of
days, the exercise parameters will start the generator. The Start Gen Days setting must be
between 1-255 days in order to enable the Gen Exercise feature.
Default setting: Start Gen Days = OFF
Range: OFF, 1-255 Days
• Set Gen Exercise ( Start Time) – This menu sets the time of day the generator starts once
it reaches the Start Gen Days setting.
Range: 12:00AM-11:45PM (15 minute increments)
• Set Gen Exercise ( Run Time) – This menu sets the maximum number of hours the generator
will run once started by the Start Gen Days and Start Time settings.
Range: 0.1-25.5 Hrs
Why should I use Gen Exercise? Exercising your generator is one of the most overlooked aspects
of routine maintenance, yet its the simplest to perform. Regularly exercising your generator
keeps engine seals and components lubricated, prevents oxidation of electrical contacts, uses
up fuel before it deteriorates, heats up the generator windings to eliminate moisture buildup,
helps ensure the generator’s starting battery is maintained at an optimal state of charge, and in
general, helps provide reliable engine starting. If long periods of time elapse without using your
generator (remains connected to external AC power), or if you only use your generator a few days
out of the year, enabling the Gen Exercise feature is recommended.
How often and how long should I exercise my generator? To maximize reliability and
minimize repairs, exercise your generator at least once per month. This applies to both gas and
diesel generators. When generators sit unused for as little as 30 days moisture can build up. 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 manufacturer 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 ( Start Time setting) whenever it has not run for a set number
of days ( Start Gen Days setting). Once the Gen Exercise feature is enabled—by setting the Start
Gen Days setting—the generator starts and begins exercising only after two conditions are met.
First, the generator must not have run for a set number of days (i.e., the days shown under the
Days Since Run timer must be equal to or greater than the Start Gen Days setting). Second, the
generator’s exercise time of day ( Start Time setting) must occur.
Info: When the generator starts and runs per 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 identi fi es the number of days since the generator has
last run by using the Since Run Days timer—see METER: 04E Since Run Days display.
