8.5 CONDITIONS OF CRANK DISCONNECT SELECTION
Table 13 Crank Disconnect Conditions
Oil pressure + Engine Speed
NOTES:
─ There are 2 conditions to make starter disconnected with engine. Engine speed and oil pressure can be used
separately. We recommend that oil pressure should be used with speed sensor together, in order to make the starter
motor separate with engine immediately and can check crank disconnect exactly;
─ Speed sensor is the magnetic equipment installed in starter for detecting flywheel teeth;
─ When set it speed sensor, users must ensure that the number of flywheel teeth is the same as settings, otherwise,
“over speed shutdown” or “under speed shutdown” may be caused;
─ If engine doesn't have speed sensor please don’t select corresponding items, otherwise, “start failure” or “loss speed
signal” may be caused;
─ If engine doesn’t have oil pressure sensor, please don’t select corresponding items.
