7.4 CONDITIONS OF CRANK DISCONNECT SELECTION
Form 4
No.
Setting Description
0
Gen frequency
1
Speed sensor
2
Speed Gen frequency
NOTES:
1. There are 2 conditions to make starter disconnected with engine, that is, speed sensor and
generator frequency. They all can be used separately. We recommend that speed sensor
should be using with generator frequency together, in order to make the starter motor is
separated with engine immediately and can check crank disconnect exactly.
2. Speed sensor is the magnetic equipment which be installed in starter for detecting flywheel
teeth.
3. When set as speed sensor, must ensure that the number of flywheel teeth is as same as
setting, otherwise, “over speed shutdown” or “under speed shutdown” may be caused.
4. If genset without speed sensor, please don’t select corresponding items, otherwise, “start fail”
or “loss speed signal” maybe caused.
5. If not select generator frequency in crank disconnect setting, controller will not collect and
display the relative power quantity (can be used in water pump set); if not select speed sensor
in crank disconnect setting, the rotating speed displayed in controller is calculated by
generator signal.
