configuration.

3. MAINTENANCE

WARNING: DO NOT OPEN THE UNIT

There are NO serviceable parts inside the unit.

Wipe the unit, if necessary with a soft damp cloth. Do not use chemical

agents.

The genset starts to operate while AC mains are OK:

AC mains voltages may be outside programmed limits. Read AC voltages by

pressing the MENU button. Upper and lower limits of the mains voltages may

be too tight. Get in the PROGRAM mode and check for the AC voltage

upper and lower limits. If necessary, widen the limits.

The genset continues to operate after AC mains are reestablished:

Widen the AC voltage limits. The hysteresis value for the AC voltages is 10

volts. When the AC mains fail, the lower limit is raised and the upper limit is

reduced by the hysteresis value to prevent a new load transfer after the load is

transferred to the mains.

AC voltages displayed on the unit are not correct:

The error margin of the unit is +/- 5 volts.

If there are faulty measurements only when the engine is running, there may

be a faulty charging alternator or voltage regulator on the engine.

Disconnect the charging alternator connection and check if the error is

removed.
