7.5 CONDITIONS OF CRANK DISCONNECT SELECTION
Table 14 – Crank Disconnect Conditions Selection
NOTE:
─ There are 3 conditions to make starter disconnected with engine. Engine speed sensor and oil pressure
both can be used separately. We recommend that oil pressure should be using with engine speed sensor
together, in order to make the starter motor is separated with engine immediately and can check crank
disconnect exactly.
─ Engine speed sensor is the magnetic equipment which be installed in starter for detecting flywheel teeth.
─ When set as engine speed, must ensure that the number of flywheel teeth is as same as setting, otherwise,
“over speed shutdown” or “under speed shutdown” may be caused.
─ If pump unit without engine speed sensor, please don’t select corresponding items, otherwise, “start fail”
or “loss speed signal” maybe caused.
─ If genset without oil pressure sensor, please don’t select corresponding items.
