Faults Causes Measures
No output signal Cable break Check the continuity
Deviating zero point signal Overpressure limit exceeded Observe the permissible overpressure safety
(see chapter "3. Specifications")
Deviating zero point signal Operating temperature too high/low Observe the permissible temperatures
(see chapter 3. "Specifications")
Constant output signal upon
change in pressure
Mechanical overload caused by
overpressure
Replace pressure transmitter; if it fails
repeatedly, contact the manufacturer
Signal span too small Mechanical overload caused by
overpressure
Replace pressure transmitter; if it fails
repeatedly, contact the manufacturer
Signal span varies EMC interference sources in the
environment; for example, frequency
converter
Shield the pressure transmitter; cable shield;
remove source of interference
Signal span varies/inaccurate Operating temperature too high/low Observe the permissible temperatures
(see chapter 3. “Specifications”)
Signal span drops/too small Signal span drops/too small Contact manufacturer and replace pressure
transmitter
If complaint is unjustified, we will charge you the complaint processing fees.
CAUTION!
If faults cannot be eliminated by means of the measures listed above, shut down the
instrument immediately, and ensure that pressure and/or signal are no longer present, and
secure the instrument from being put back into operation inadvertently. In this case, contact
the manufacturer. If a return is needed, please follow the instructions given in chapter 9.2
"Return".
