7.2 Connection of Power Supply
Inappropriate choice of power supply or insufficient battery capacitance or incorrect
connection of the power supply line or too small cable sizes of the feed line and the motor
line of the positioner are bound have an adverse effect upon the performance of the speed
governor. In steady state operation, this will cause a heavy increase of current consumption
and unnecessary vibration of the positioner drive. The high current consumption will in its
turn lead to overheating of the actuator or the position control unit, and the vibration will
result in premature wear of the gear and bearing parts or of the linkage.
NOTE: In altogether, the lifetime of the control system is distinctly reduced by the
errors described above

The ripple voltage of the charger is fed

1) Coils (e.g. stopping solenoid, gas valve) have to be equipped with a protective circuit to eliminate high
indunctance votages. Diode type e.g. 1N4002

If there are battery chargers with rapid charge mode installed in the plant,
the rapid charge mode should no be used during operation.
