DKG-519 User Manual V-27

(14.04.2011)

The unit is late to remove engine cranking:

-The generator voltage rises lately. Also the generator remnant voltage is below 20 volts. The unit
removes starting with the generator frequency, and needs at least 20 volts to measure the frequency.
If this situation is to be avoided, the only solution is to add an auxiliary relay. The coil of the relay will
be between BATTERY (-) and charging alternator D+ terminal. The normally closed contact of the
relay will be connected serially to the unit's START output. So the starting will also be removed when
the D+ pulls to battery positive.

The unit is inoperative:

Measure the DC-supply voltage between terminals BAT+ and BAT- at the rear of the unit. If OK, turn
all the fuses off, then turn all the fuses on, starting from the DC supply fuse. Then test the unit again.

Programming mode can not be entered:

The program lock input disables programming mode entry. Disconnect the program lock input from
battery negative before modification. Do not forget to make this connection again to prevent
unauthorized program modifications.

Some program parameters does not appear:

A higher password level is required.

AUTO led flashes and the genset does not run when REMOTE START signal arrives:

The unit is in Weekly Schedule

OFF

time. Please check date and time setting of the unit. Please

check also Weekly Schedule program parameters.
