INSTALLATION PRECAUTIONS
Install the device as shown in the picture
-
Ensure that the working conditions are within the limits stated in the TECHNICAL
-
SPECIFICATIONS section
Do not install the device close to heat sources, equipment with a strong magnetic field,
-
in places subject to direct sunlight, rain, damp, excessive dust, mechanical vibrations
or shocks
Clean the protective cap periodically (unscrew the cap from the main part of the device
-
and clean it using low pressure compressed air or distilled water).

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.
