Fault profile (symptoms) Possible cause(s) Corrective measures
Zero point displaces sporadically (> 3%). Impact or shock loads result in acceler‐
ations so high that the friction clutch
moves, e.g. due to "vapor shocks" in va‐
por lines.
● Rectify the causes for shock loads.
● Re-initialize the position controller.
The device function has completely
failed: No representation on the display
either.
Electrical auxiliary power supply is not
adequate.
● Check the electrical auxiliary power
supply.
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.
● Tighten the screws firmly and secure
using sealing wax.
● Repair
● For prevention: Install the positioner
on the damping pads.
