The genset operates while AC mains are OK or continues to operate after AC mains are OK:

-Check engine body grounding.
-AC mains voltages may be outside programmed limits, measure the phase voltages.
-Check the AC voltage readings by pressing the MENU button.
-Upper and lower limits of the mains voltages may be too tight. Check the parameters

Mains Voltage

Low Limit

and

Mains Voltage High Limit

. Standard values are 170/270 volts.

-The hysteresis voltage may be given to excessive. The standard value is 8 volts.

AC voltages or frequency displayed on the unit are not correct:

-Check engine body grounding, it is necessary.
-The error margin of the unit is +/- 3 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  of  the
engine and check if the error is removed.
-If  there  are  faulty  measurements  only  when  mains  are  present,  then  the  battery  charger  may  be
failed. Turn off the rectifier fuse and check again.

Phase-to-Phase AC voltages are not correct although Phase to Neutral voltages are correct:

-Incorrect phase order. Please connect phase voltages in the correct order.

KW and cosΦ readings are faulty although the Amp readings are correct:

-Current transformers are not connected to the correct inputs or some of the CTs are connected with
reverse polarity. Determine the correct connections of each individual CT in order to obtain correct KW
and cosΦ for the related phase, and then connect all CTs.

Short circuit the outputs of unused Current Transformers.

When the AC mains fails the unit energizes the fuel solenoid, but does not start and OIL
PRESSURE EXISTS ! message is displayed:

The unit is not supplied with battery (-) voltage at the oil pressure input.
-Oil pressure switch not connected.
-Oil pressure switch connection wire cut.
-Oil pressure switch faulty.
-Oil pressure switch closes too lately. If oil pressure switch closes, the unit will start. Optionally oil
pressure switch may be replaced.

The engine does not run after the first start attempt, then the unit does not start again and OIL
PRESSURE EXISTS ! message is displayed:

-The oil pressure switch closes very lately. As the unit senses an oil pressure, it does not start. When
oil pressure switch closes the unit will start. Optionally the oil pressure switch may be replaced.
