Operation Manual of WEICHAI GENSET
Shutdown alarm icon
The fault must be removed before restart. If the alarm condition is present, the
controller will not restart (except for low oil pressure alarm and similar safety alarm,
because the oil pressure is very low when the engine is in standby state).
The alternator will be locked and stopped immediately after the shutdown alarm is
given. When the shutdown becomes valid, the controller will cut off all delay load
outputs and turn off the alternator output to remove the load. Once this condition
happens, the controller will immediately stop all sets from operating, to prevent this
condition from worsening. The controller can only be restarted after the reception and
release of the alarm and removal of the fault.
As the alarm will be locked by shutdown, to remove the fault, please press the
Stop/Reset button.
