Check the 4 ... 20 mA signal
Connect a multimeter in the suitable measuring
range according to the wiring plan.
Error Cause
4 ... 20 mA No atmospheric
signal not pressure compen-
stable sation
4 ... 20 mA Wrong connection
signal mis- to voltage supply
sing
No power supply
Operating voltage
too low, load resis-
tance too high
In Ex applications, the regulations for the
wiring of intrinsically safe circuits must
be observed.
5.3 Shorten suspension cable
Shorten the suspension cable individually.
Proceed as follows:
1. Remove the filter adapter from the capillary
line
2. Cut the suspension cable to the requested
length with side cutters
Caution:
Do not squeeze the capillary cable, as
this will impair the pressure compensati-
on. If necessary, rework the capillary with
a sharp knife.
3. Remove approx. 10 cm of the cable mantle,
strip off approx. 1 cm of insulation from the
ends of the wires
4. Insert the filter adapter
The work steps are finished.
