The unit offers 7 independent automatic exercisers. The exercise operation may be done on a weekly or
monthly basis.
The start day and time of the exercise is programmable as well as its duration. The exercise may be done
with or without load following programming.
Program parameters related to the exerciser are:
Exercise start day and hour
Exercise duration
Exercise off_load/on_load
Please refer to the programming section for a more detailed description of the above parameters.
When the start day and hour of exercise has come, the unit will automatically switch to either RUN or
TEST mode. The engine will run. If the on_load exercise is selected then the load will be transferred to
the genset.
If a mains failure occurs during the off-load exercise, the load will not be transferred to the genset unless
the
Emergency Backup Operation is allowed by setting the related program parameter to 1. Thus it is
highly recommended that the Emergency Backup mode enabled with off-load exerciser.
At the end of the exercise duration, the unit will switch back to the initial mode of operation.
If any of the mode selection keys are pressed during exercise, then the exercise will be immediately
terminated.
Using the weekly exercise mode and with suitable parameter setting, the unit may feed the load from the
genset during predefined hours of each day. This operation may be used in high tariff periods of the day.
In most applications, the genset is requested to operate only in working hours. Thanks to the weekly
program feature, unwanted operation of the genset may be prohibited.
The scheduler is active only in AUTO mode. When the scheduler prevents genset operation in AUTO
mode, the AUTO led will flash.
The scheduler consists of 144 programmable parameters, one for each hour in a week. Thus every hour
of the week may be independently selected as ON or OFF times.
These programmable parameters allow the genset to operate automatically only in allowed time limits.
The unit has a battery backed-up precision real time clock circuit. The real time clock circuit will continue
its operation even in power failures. The real time clock is precisely trimmed using the
Real Time Clock
Adjust program parameter. For more details check the programming section.
When the scheduler prevents genset operation in
AUTO mode, the AUTO led will flash.
