5 Positioning Control System
12 Digital Positioning System 2000
Altogether, this type of positioner offers following advantages:
- High regulating power working in either direction.
- Extremely low current consumption during steady state and relatively low current
consumption on changes of load.
- Indifference to slow voltage changes of power supply; abrupt voltage changes,
however, will cause governor disturbances.
5.3 Installation
The positioner must be firmly mounted on the engine using a support with stiffened
brackets. Vibrating arrangements as may be caused by weak bracket material or missing
stiffenings must be avoided by all means as this will increase vibrations and lead to faster
wear of positioner and linkage.
