9 Actuators
Digital Governor Basic System PANDAROS II 27
Altogether, this type of actuator provides the following advantages:
- High regulation power working in both directions.
- Extremely low current consumption during steady state and relatively low current con-
sumption on change of load.
- Indifference to slow voltage changes of the supply; abrupt voltage changes cause gov-
ernor disturbances.
- maintenance-free
9.1 Variations
The actuator can be equipped with either a terminal strip or a plug-in connector.
Currently the following basic variations are available:
Actuators with plug-in connections
Actuators with terminal strips
The xx in the designations are representing additionally differences at the variations, for
exsample:
Operating angle (standard 36°, optional 68°)
Connection plug (standard 5 pole with thread, optional 6 pole or bayonet)
Feedback (standard analogue, optional additionally with temperature compensation)
Return spring (standard installed, optional without or reinforced)
The exact type designations are available on request.
9.2 Installation
The actuator must be mounted firmly on the engine by means of reinforced brackets. Un-
stable arrangements, as caused by weak bracket material or missing stiffenings, have to be
avoided by all means; they are bound to intensify vibrations, which will lead to premature
wear of the actuator and the connecting linkage!
Generally any mounting position is possible; however, the actuators should not be mounted
with the plug connection pointing straight upward.
