These sensors are equipped with a pre-assembled cable ex-
factory. This cable is permanently connected to the sensor at one
end. The end leading to the transmitter is fitted with a cable
gland and pre-prepared cable ends for connection. The attached
wire numbers serve for orientation.

Anschluss HART
®
A number of options are available for HART
®
communication.
However, for all these options loop resistance must be less than
the maximum load specified in Chapter „Outputs“ (see page 6).
The HART
®
-Interface is connected via terminals 8 and 9 of the
(active) current output.
The minimum load impedance is 250Ω.

Zero point adjustment
Below the mains transformer, next to the lights and the data
storage module (DSB), there is a switch for adjusting the zero
point. In order to reach the switch, the transducer must be
opened by unscrewing the front cover and removing the
decoration foil.
For processing the zero point adjustment please observe the
advices in Section “Zero point calibrationon” on page 4.
