10.2 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 actuator 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 actuator drive. The high current consumption will in its
turn lead to overheating of the actuator or the amplifier in the control unit, and the
vibration will result in premature wear of the gear and bearing parts or of the linkage.
In altogether, the lifetime of the control system is distinctly reduced by the
errors described above.
The following figure shows both a wrong and a correct cabling:
