ELECTRICAL CONNECTION

N.B.
- the temperature transducer works provided that the humidity one is correctly
powered
- to reduce any electromagnetic interference locate the power cables as far away as
possible from the signal cables.
4.1

Electrical connection EVHP523

Transducer calibration:
0... 100 % of relative humidity; they correspond respectively to 4 and to 20 mA.
4.2

Electrical connection EVHTP523

Humidity transducer calibration:
0... 100 % of relative humidity; they correspond respectively to 4 and to 20 mA.
Temperature transducer calibration:
-30... 70 °C; they correspond respectively to 4 and to 20 mA.

PRECAUTIONS FOR ELECTRICAL CONNECTION

-
If the device has been moved from a cold to a warm place, the humidity may have
caused condensation to form inside. Wait about an hour before connecting it to the
controller
Disconnect the device from the controller before doing any type of maintenance
-
For repairs and for further information, contact the EVCO sales network.
