Fault
Possible causes
Fault detection / remedy
No output signal:
Connected incorrectly.
Check the connections!
Conductor/wire breakage.
Check all wires with cable tester!
Defective measuring device (signal input).
Check the ampere meter (and its fuse) and the analogue input of the signal processing unit!
Analog output signal too low:
Load resistance too high.
Check the value of the load resistance!
Supply voltage too low.
Check the power supply and power / current on the transducer / transmitter!
Slight shift of the output signal:
The diaphragm of the sensor is severely
contaminated.
Cleaning with non-aggressive cleaning solutions, soft brush or sponge.
The diaphragm of the sensor is calcified or crusted. It is recommended to clean carefully and remove dirt.
Large shift of the output signal:
The diaphragm of the sensor is damaged (caused
by overpressure or mechanically).
Check the diaphragm of the sensor, if it is damaged then send the device back to the

7. MAINTENANCE AND REPAIR
The instrument does not require regular maintenance. If necessary possible dirt deposited should be cleaned off. The repair will be carried out at the NIVELCO' premises only.
When dismantling the device, it must always be done in the depressurized and currentless condition! Check also if the medium has to be drained off before dismantling.
If necessary, clean the diaphragm carefully with non-aggressive cleaning solution, soft brush or sponge. Wrong cleaning or improper touch may cause irreparable damage on the
diaphragm. Therefore, never use pointed objects or pressured air for cleaning the diaphragm.
Before returning your device for repair, it has to be cleaned carefully, neutralize/decontaminate the harmful substances at the media wetted parts. Beside our appropriate form
