Fault indication
(symptoms)
possible cause(s)
Remedies
•
Zero point misadjusts
sporadically (> 3 %).
•
Stress caused by knocks or
shocks result in acceleration
values that are so high that the
friction clutch is misadjusted
(e.g. with “steam pulses” in
steam lines)
•
Eliminate causes of shock
stress.
•
Re-initialize positioner.
•
Complete device function
failure: also no indication in
the display
•
Electrical power supply
insufficient
•
Check electrical power supply.
•
In the event of continuous high
vibration stress (vibrations):
•
Screws on the electrical
connecting terminals can
loosen.
•
Electrical connecting terminals
and/or electronic components
can loosen due to vibrations.
•
Tighten screws and secure
them with locking varnish.
•
Repair (see chapter 5,
page 145)
•
For prevention purposes:
Fit SIPART PS 2 on shock
mounts.
