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

The following specific fields are supported
10. Trouble shooting GB
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
register supports only error 1(= general 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
