7.5 CONDITIONS OF CRANK DISCONNECT SELECTION
Table 11 ā Crank Disconnect Conditions Selection
1) There are 3 kinds of crank disconnect conditions. Speed, generator frequency and oil pressure can
be used alone. Oil pressure is used with speed and the generator frequency together is
recommended, in order to make the starter and the engine disconnect as soon as possible.
2) Speed is the signal measured by magnetic sensor, which is installed in the engine for testing
flywheel teeth.
3) When choosing speed, ensure the number of flywheel teeth is same as the pre-set, otherwise over
or under speed shutdown may appear.
4) If generator has no magnetic pickup sensor, don't choose speed item; otherwise Fail to Start or
Loss of Speed Signal shutdown will occur.
5) If the generator has no oil pressure sensor, don't choose corresponding item.
6) If generator frequency has not been selected, controller will not measure and display the relative
parameters (can be applied to the pump set); if speed has not been selected, the speed will be
calculated by the generating signal.
