generator frequency can be used separately while oil pressure must 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 which be installed in starter for detecting
flywheel teeth.

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” maybe caused.
