Manual

Trouble shooting
Service
• The pressure transmitters do not require any maintenance.
• In the event of a fault, there are no components or modules
which can be replaced or repaired by the user.
Please return the instrument to the supplier, with a detailed
description of the fault.
• We recommend to recalibrate the devices annually.

Type of fault Possible cause Handling
No output signal No voltage supply Check voltage
supply
Cable break, incorrect
connection
Check connecting
cables
No input pressure Check connection to
the pressure
medium
Fault in pressure transmitter,
caused by impermissible
operating conditions
Retur the pressure
transmitter to the
supplier, with a
detailed description
of the fault
Output signal
stays constant,
even though the
pressure
changes
Measurement system of
the device has been
destroyed by excessive
pressure
Output signal from the
pressure transmitter is
being distorted by the
current limiting, resulting
from overvoltage
Provide the correct
voltage supply
Measurement range
is too small – return
the pressure
transmitter to the
supplier, with a
detailed description
of the fault
Measurment point is
blocked
Check
measurement point,
if necessary clean or
replace it
Output signal
too high
Selected measurement
range is too low
Return the pressure
transmitter to the
supplier, with a
detailed description
of the fault
The electronics of the
pressure transmitter is
faulty, or the voltage supply
is too high
Output signal
too low
With current output signal:
burden is too high
With voltage output signal:
burden is too low
Change the burden
on the measurement
circuit
Voltage supply is too low Alter the voltage
supply
Zero of the out-
put signal is
wrong
Pressure transmitter
measurement has shifted
because of impermissible
operating conditions (e.g.
overpressure)
Return the pressure
transmitter to the
supplier, with a
detailed description
of the fault
Output signal
characteristic is
not linear
