Possible cause(s)
Remedial measures
•
Zero point displaces sporadically
(> 3%).
•
Impact or shock loads result in
accelerations so high that the
friction clutch moves, e.g. due to
"vapor shocks" in vapor lines.
•
Rectify the causes for shock loads.
•
Re-initialize the positioner.
•
Electrical auxiliary power supply is
not adequate.
•
Check the electrical auxiliary power
supply.
•
The device function has completely
failed: no view even on the digital
display.
•
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.
•
