DKG-225 User Manual Firmware V-01
- 44 -
When the AC mains fails, the engine starts to run but the unit gives A07-START FAIL alarm
and then the engine stops:
-The generator phase voltages are not connected to the unit. Measure the AC voltage between
terminals
GEN L1-L2-L3
and
Generator Neutral
at the rear of the unit while the engine is running. A
fuse protecting the generator phases may be failed. A misconnection may be occurred. If everything
is OK, turn all the fuses off, and then turn all the fuses on, starting from the DC supply fuse. Then test
the unit again.
The unit is late to remove engine cranking:
-The generator voltage rises lately. Also the generator remnant voltage is below 14 volts. The unit
removes starting with the generator frequency, and needs at least 14 volts to measure the frequency.
If this situation is to be avoided, please enable crank cutting with oil pressure and charge alternator
voltage.
The unit is inoperative:
Measure the DC-supply voltage between terminals 2 and 4 at the rear of the unit. If OK, turn all the
fuses off and disconnect the battery, then turn all the fuses on and reconnect the battery, then test the
unit again.
Some program parameters are skipped:
These parameters are reserved for factory setting and cannot be modified.
