FAQ
Is the clock of the engine exerciser accurate?
The engine exerciser clock is moderately accurate. If the generator exercises out of schedule check
the following:
Verify on the event log that the event recorded was an engine exercise.
The PRESENT DATE/TIME setting under the engine exerciser menu should be synchronized with
the present date and time.
The event of engine exercise should fall within any of the enabled P1 to P7 settings.
The generator should not have its own exerciser program.
After checking all of the above and the problem is still there, contact an ASI service technician.
What is an in-phase monitor?
An In-phase monitor is a motor load transfer feature that monitors the voltage and frequency of the two
sources. It ensures that the voltage and the frequency of the two sources are within acceptable phase
angles (in electrical degrees) before the ATS transfers the load between two live sources to avoid
nuisance tripping on the breakers or physical damage to motors.
