NOTE
•
Do not connect the starter motor relay and the stop solenoid directly to the controller's output terminals.
•
Genset and mains contactor latching relays should be compiled against 4 kVA surge as per IEC-61000-4-5 standard.
3.12 Rotary actuator outputs (SGC 121 only)
Category
Controller terminal
Type
Max. current
The actuator outputs are used only for the Rotary actuator, if installed. The Rotary actuator is a 4-wire actuator that is used for
creating an electronic governing application in case of a mechanical fuel system engine. In diesel engines, the Rotary actuator's
shaft output gets mechanically connected to the stop lever or the throttle lever of an in-line or rotary fuel injection pump. In case of
petrol or natural gas engines, the Rotary actuator's shaft output gets connected to the throttle/charge control valve.
It is recommended to follow the connection details of the Rotary actuator connector and SGC 121.
