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. Specications")

Deviating zero point signal Operating temperature too high/low Observe the permissible temperatures

(see chapter 3. "Specications")

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. “Specications”)

Signal span drops/too small Signal span drops/too small Contact manufacturer and replace pressure

transmitter

If complaint is unjustied, 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
