1) There are 3 conditions to make starter separated with engine; magnetic pickup, generator frequency
and oil pressure, which can be used separately, but oil pressure is suggested to be used together with
magnetic pickup and generator frequency. The aim is to disconnect the starter motor as soon as
possible.
2) Magnetic pickup is the magnetic equipment installed in starter for detecting flywheel teeth.
3) When magnetic pickup is selected, please ensure the number of flywheel teeth is the same as setting,
otherwise, "over speed shutdown" or "under speed shutdown" may be caused.
4) If genset without magnetic pickup, please don't select corresponding items, otherwise, "start fail" or
"loss speed signal" may be caused.
5) If genset without oil pressure sensor, please don't select corresponding items.
6) If generator frequency is not selected in crank disconnect settings, controller will not collect and
display the relative power quantity (can be used in water pump set); if magnetic pickup is not selected
in crank disconnect setting, the engine speed displayed in controller is calculated by generator signal.
