Faults Causes Measures
No output signal. Insucient supply voltage or cable
break.
Check voltage supply and
cables.
Wrong pin assignment. Check pin assignment.
Defective transmitter electronics due
to overvoltage.
Constant output signal
upon change in pressure.
Pressure port blocked at process
connection.
Clean pressure port at pro-
cess connection
Supply voltage connected the wrong
way. (I = ca. 4.5 mA).
Check pin assignment.
Defective transmitter electronics Replace instrument.
Too high, constant output
signal upon change in
pressure.
Bridge on terminals 5 and 6 not
removed (I = approx. 9.5 mA).
Remove the terminal bridge.
See chapter 5.3. “Zero point
setting”.
Defective transmitter electronics due
to overvoltage.
Replace instrument.
Signal span too small. Insucient supply voltage. Check voltage supply and
cables.
Load too high. Maintain permissible load.
Zero point maladjusted. See chapter 5.3. “Zero point
setting”.
Zero point signal too low or
too high.
Zero point maladjusted. See chapter 5.3. “Zero point
setting”.
For the exchange of the instrument chapters 8 “Dismounting, return and disposal” and 5
“Commissioning, operation” must be observed.
7. Maintenance and cleaning
7.1 Maintenance
The instruments are maintenance-free.
The indicator and switching function should be checked once or twice every year. For this
the instrument must be disconnected from the process to check with a pressure testing
device.
Testingoflledinstruments
For lled instruments, the level must be checked once or twice every year.
The liquid level must not drop below 75 % of the instrument diameter.
