Description
This feature is especially designed for specific applications, which are supposed to start the engine
manually (air starter, external cranking) and controller need to accept running engine. This function is also
used in case of Controller redundancy to disable redundant controller.
The controller behaves following way:
Shows the text EmergMan in the engine status on the main screen.
Stops all functions regarding the Controller control, deactivates all outputs related to it. The
complete list of effected logical binary outputs is bellow this text.
Stop Fail alarm is not beeing evaluated and stop solenoid is not activated if non-zero speed is
detected.
Note: For successful recovery to a running state when the input is deactivated it is recommended to use
pulse-type control outputs instead of continous-type. E.g. STOP and S

OLENOID
for fuel supply
control and application (clutch, GCB coilGCB ON coil, GCB OFF coil for breaker control.
Logical Binary Outputs that are deactivated (directly or indirectly) when Emerg. manual is active could be
(only if they are available in controler FW): Starter, Fuel solenoid, Prestart, Cooling pump, Stop solenoid,
Stop pulse, Speed up, Speed dn, AVR up, AVR dn, Ignition, Ventilation, Idle/Nominal, Prelubr pump,

Description
If the input is activated, engine shutdown is immediately performed. However, the controller behavior is
slightly different compared to other shutdown alarms:
Outputs Cooling pump and Prelubrication are deactivated as well.
This input cannot be overriden with the input Sd override.
Note: Because of safety reasons it is recommended to configure this input as Normally closed and use a
NC switch.
IMPORTANT: This is a software function only. It can be extended by a "hard wired"
emergency stop function, which means disconnecting power supply from the controller
outputs.
