Possible cause(s)
● Impact or shock loads result in
accelerations so high that the friction
clutch moves, e.g. due to "vapor
shocks" in vapor lines.
● Electrical auxiliary power supply is
not adequate.
● In case of very high continuous
loads due to vibrations (oscillations):
● Screws of the electrical connecting
terminals may be loosened.
● Electrical connecting terminals and/
or electronic components may be
knocked out.
Corrective measures
● Rectify the causes for shock loads.
● Re-initialize the position controller.
● Check the electrical auxiliary power
supply.
● Tighten the screws firmly and secure
using sealing wax.
● Repair
● For prevention: Install the positioner
on the damping pads.
