Subject to change without notice
6. FAULTS
Possible cause
Line break
No/Incorrect auxiliary energy
Wiring error or switchover of switching logic/analog signal
Mechanical overload due to excessive pressure
Overload pressure limit exceeded
Mechanical overload due to excessive pressure
Auxiliary voltage too high/low
Moisture has entered the device
Membrane damage, e.g. caused by abrasive/aggressive
media, corrosion to membrane/process connection
Description
When the switching point was changed, the reset switching point was automatically
lowered by the smallest hysteresis of 0.25% by the device.
Zero point offset, prevailing pressure outside the limits
Password entry for menu access faulty
Unit cannot be shown on the display, previous unit is used
Measure
Check passage
Correct auxiliary energy
Observe pin assignment
Check output configuration
Observe pin assignment
