Contents Byte 4 Meaning Note

01h internal error *

02h internal error possilbly mechanical failure

04h Pressure value more than 5 % of span above MBE

08h Pressure value more than 5 % of span below MBE

10h Temperature at sensor exceeds 80 °C

40h internal error *

Failure Possible cause Procedure

No output signal Cable break Check connections and cable

No/incorrect voltage supply or current

spike

Adjust the voltage supply to correspond

with the Operating Instructions *)

No output signal Incorrectly wired

Follow pin assignment (see Instrument

Label / Operating Instructions)

Output signal unchanged after change

in pressure

Mechanical overload through over-

pressure

Replace instrument; if failure reoccurs,

consult the manufacturer *)

Wrong supply voltage or current spike Replace instrument

Communication problems

Electromagnetic interference source in

the vicinity, e.g. inverter drive

Shield the device; shield the cables;

remove the interference source.

Signal span dropping off/too small

Diaphragm is damaged, e.g. through

impact, abrasive/agressive media;

corrosion of diaphragm/pressure

connector; transmission fluid missing

Contact the manufacturer and replace

the instrument

Signal span too small Power supply too high/too low

Correct the power supply in line with

the Operating Instructions

Mechanical overload through over-

pressure

Re-calibrate the instrument *)

Signal span drops off Moisture present (e.g. at the cable tail) Install the cable correctly

internal device error, hardware reset required for recovery

The following specific fields are supported

10. Trouble shooting

Please verify in advance if pressure is being applied (valves/ ball valve etc. open) and if the

right voltage supply has been chosen?

In case of unjustified reclamation we charge the reclamation handling expenses.

*) Make sure that after the setting the unit is working properly. In case the error continues to exist send in the instrument for reparation (or

replace the unit).

Error Coding

This applies only for error reports which are sent by means of emergency messages. The error

Byte 1 = Low byte of error codes

Byte 2 = High byte of error codes

Byte 3 = Current contents of error registers

Byte 4 = Manufacturer -specific error

Byte 5 - 8 = Unused

1 2 ... 8 9 10 11 12 13 14 15 16 17 18 ... 30 31
