NOTES:
1) There are 3 conditions to make starter separate with engine; speed, generator frequency and oil pressure. All can be
used separately. It is suggested that oil pressure shall be used together with speed and generator frequency. The
aim is to disconnect the starter motor as soon as possible.
2) Speed stands for the real rotation speed detected by the speed sensor. Speed sensor is the magnetic equipment
which is installed in the starter for detecting flywheel teeth.
3) When speed is chosen, make sure that the number of flywheel teeth is the same as the set value
, otherwise, “over
speed shutdown” or “under speed shutdown” may be caused.
4) If genset is without speed sensor,
please don’t select corresponding items, otherwise, “start fail” or “loss speed
signal” maybe caused.
5) If genset is
without oil pressure sensor, please don’t select corresponding items.
6) If generator frequency is not chosen in crank disconnection setting, the controller will not collect and display the
relative power quantity (can be used in water pump set); if speed is not chosen in crank disconnection setting, the
engine speed displayed is converted by generator frequency and generator poles.
