2.1 4-20mA OUT The analogue current output can be set to fixed values in 10
% increments from 4.00...20.00mA. This function has no
influence on the binary switching outputs.

3.2 FUNCTION B1 INACTIVE Output B1 is switched off.
SWITCHING
POINT
The output B1 switches at a set value depending on the
current level value.
3.3 CONTACT B1 NC contact Output B1 is normally closed. If an alarm situation occurs,
the contact opens.
NO CONTACT Output B1 is normally open. If an alarm situation occurs,
the contact closes.

3.9 MULTIDROP 0…15 Multi-drop mode means that the device is continuously
working in bus mode via HART
® communication (max. 15
parallel devices). The analogue current output is then fixed
to 4.1 mA. Measured values are transmitted via HART
®
communication. However, the display allows local reading
of the measured values. The polling address can be set to 1
.... 15. Larger whole numbers are not permitted. If the
polling address is set to 0, HART
® bus mode is switched off.
The device functions as analogue. The current output of 4-
20mA is active. Standard HART
® communication is further
guaranteed.
