Ambient alert An alarm for overshooting/undershooting of permitted ambient temperature is
deactivated here.
Input:
• on
•off
!
Note!
If the ambient temperature alarm is deactivated then the unit will not go into alarm
but will transmit a warning. Change is the responsibility of the user.

Corrosion
detection
Sensor connection cable corrosion can lead to false measured value readings.
Therefore our unit offers the possibility to recognize any corrosion before the
measured values are affected. (see chapter 9.2.1).
There are 2 different steps selectable dependent on the application requirements:
• off (warning output just before reaching the alarm set point. This allows for
preventative maintenance/trouble-shooting to be done.)
• on (no warning, immediate alarm)
++V2H4
Alarm for
undershooting
/overshooting
Input:
• Off
If the measuring range is undershot or overshot, the output signal is
temperature-linear up to 3.8 mA or 20.5 mA and remains at these values (as per
NAMUR NE43).
•On
An error is signalled if the measured temperature corresponds to an output value
< 3.8 mA or > 20.5 mA, (see 'Fault condition').
