SUPPLY VOLTAGE:
For operating voltage reverse polarity protection, a one-way rectifier or
reverse polarity protection diode is integrated in this device variant.
If this device is operated with a DC supply voltage , the operating voltage
input UB+ is to be used for 15...36 V DC supply and UB – or GND for ground
wire!
If several devices are supplied by one 24 V
AC voltage supply
, it is to be
ensured that all "positive" operating voltage input terminals (+) of the field
devices are connected with each other and all "negative" operating voltage
input terminals (–) (= reference potential) are connected together (in-phase
connection of field devices). All outputs of field devices must be referenced
to the same potential!
In case of reversed polarity at one field device, a supply voltage short-
circuit would be caused by that device. The consequential short-circuit
current flowing through this field device may cause damage to it.
Therefore, pay attention to correct wiring!

READOUT IN THE DISPLAY
The 1st line of the display shows the relative humidity.
The 2nd line shows on the left side the information
regarding the
switching status of the relay (as a circuit),
as well as the switching value readout in % r.H.
on the right side (adjustable using the set potentiometer).
○
Circuit, empty = relay in idle state
●
Circuit, full = relay energised
Zero point calibration
The sensors are pre-set and calibrated at the factory.
Adjustment is possible using the offset potentiometer.
Range of adjustment: approx. ± 10 % r.H.
