11.4.6 Remedial measures table 5
Fault profile (symptoms) 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.
• Repair
1)
• For prevention: Install the positioner
on the damping pads.
