NOTE:
1. There are 3 conditions to make starter disconnected with engine, that is, speed sensor,
generator frequency and engine oil pressure. They all can be used separately. We
recommend that engine oil pressure should be using with speed sensor and 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 genset without oil pressure sensor, please don‟t select corresponding items.
6. If not select generator 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 frequency and number of poles.
