Warning relay The pressure pick-up for the
measuring chamber is not deliv-
ering plausible values (<500 hPa
or > 1500 hPa)
Warning relay HT is lower than 0 °C or higher
than 150 °C
No fault at the device!
The Dew point is lower than -
25 °C or higher than 100 °C
Warning relay No fault at the device! Warning
when measurand is too low.
The value for analogue output A1
(A2) is lower than the lower
measuring range limit
Warning relay No fault at the device! Warning
when measurand is too high.
The value for analogue output A1
(A2) is higher than the upper
measuring range limit
Warning relay No fault at the device!
The measurand is lower than the
programmed low limit.
Warning relay No fault at the device!
The measurand is higher than the
programmed high limit.

Actions
 Read the value for SP ( SP key)
and compare it with the external
barometer if appropriate
 If the compressed air is switched
off, the pressure should adjust to
the prevailing ambient baromet-
ric pressure
 Make a note of the result and
consult the service centre.
 Check HT sensor and its con-
nection for short circuit or inter-
ruption
 If the sensor is defective  re-
place it
 Check conditions at the sam-
pling position.
 Check programming (menu
PRG.-OUTPUT)
 Check conditions at the sam-
pling position
 Check programming (menu

 Check conditions at the sam-
pling position.
 Check programming (menu SET
LIMITS)
 Check conditions at the sam-
pling position.
 Check programming (menu SET
LIMITS)
 Wait till the working conditions
are established after switching
on.
 Check TT and HT sensor.
 Check pressure in the measur-
ing chamber (SP)
 Check hose heating connection
 Check hose heating for defects
 Consult the service centre
 Check fuse
