Example of a Gen Exercise Scenario:
Under SETUP: 04H Gen Exercise menu, set to: Start Gen Days = 3, then set Start Time =
8:30AM, and then set Run Time = 1.0 Hours.
Under CTRL: 03 Gen Control, set to AUTO.
First required condition: The Days Since Run timer must have accumulated to at least 3 days
(Start Gen 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 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.
Second required condition: The router’s clock must now go to 8:30 AM (Set Gen Exercise:
Start Time = 8:30A) before the generator 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 1 hour (Set Gen Exercise Run Time = 1.0 Hrs).
Info: If the generator does not start (e.g., AGS fault, gen runs out of fuel, etc.,) despite
the gen exercise start criteria being met, an additional day must increment before
another attempt is made.
SETUP: 04I Gen No-Load Time Menu
This menu’s warm-up setting allows the generator to run (i.e., warm up) before it connects to the
inverter/charger, or powers the battery charger and any pass-thru loads. Most generators need
to warm up before a load is supplied—similar to warming up your car before driving it.
This menu’s cooldown setting allows the generator to continue to run unloaded after it disconnects
from the inverter and prior to autostopping (i.e., cool down). Allowing the generator to cool down
after the load is disconnected helps to prolong generator engine life (especially diesel engines
with turbos).
• Set Gen No-Load Time ( Warm-up) – This setting is the amount of time the generator is
allowed to warm up before connecting to the inverter/charger.
Default settings: Warm-up = 60 secs
Ranges: 0-127 Seconds, then 1-127 Minutes
Where should I set Gen Warm-up Time? Check with your generator manufacturer. Typically,
smaller generators (~2-3 kW) need at least 60 seconds to warm up before applying a load; larger
generators require a longer warm-up time.
• Set Gen No-Load Time ( Cooldown) – This setting is the amount of time the generator is
allowed to cool down after it disconnects from the inverter/charger.
Default settings: Cooldown = 60 secs
Ranges: 0-127 Seconds, then 1-127 Minutes
Where should I set Gen Cooldown Time? Check with your generator manufacturer. Typically,
smaller generators (~2-3 kW) need at least 60 seconds to cool down after being disconnected
from a load; larger generators require a longer cooldown time.
Info: The warm-up and cooldown features prevent the generator from connecting to
the inverter’s AC input. Since the inverter only has a single-source input, it cannot
distinguish between grid or generator input. So, during the warm-up or cooldown time,
the inverter prevents any AC input from connecting. Also, when either warm-up or
cooldown is activated, any AC source (i.e., grid or generator) connected to the inverter’s
AC input disconnects until the time period (warm-up or cooldown) is over.
