MEASUREMENTS AND INSTALLATION

Measurements in mm (in); 59.0 (2 5/16) depth with fixed screw terminal blocks, 81,5
(3 3/16) depth with plug-in screw terminal blocks.
To be fitted to a panel, snap-in brackets provided.

INSTALLATION PRECAUTIONS

- the thickness of the panel must be between 0.8 and 2.0 mm (1/32 and 1/16 in);
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;
in compliance with safety regulations, the device must be installed properly to ensure
-
adequate protection from contact with electrical parts. All protective parts must be
fixed in such a way as to need the aid of a tool to remove them.

ELECTRICAL CONNECTION

N.B.
- use cables of an adequate section for the current running through them.
- ensure that the thermocouple is properly insulated from contact with metal parts or
use already insulated thermocouples.
- if necessary, extend the thermocouple cable using a compensating cable.
- to reduce any electromagnetic interference locate the power cables as far away as
possible from the signal cables.

PRECAUTIONS FOR ELECTRICAL CONNECTION

- if using an electrical or pneumatic screwdriver, adjust the tightening torque;
if the device has been moved from a cold to a warm place, humidity may have caused
-
condensation to form inside. Wait about an hour before switching on the power;
make sure that the supply voltage, electrical frequency and power are within the set
-
limits. See the section TECHNICAL SPECIFICATIONS;
- disconnect the power supply before carrying out any type of maintenance;
do not use the device as safety device;
-
for repairs and for further information, contact the EVCO sales network.

FIRST-TIME USE

1. Install following the instructions given in
INSTALLATION.
2. Power up the device as set out in the section ELECTRICAL CONNECTION: an internal
test will start up.
The test normally takes a few seconds; when it is finished the display will switch off.
3. Configure the device as shown in the section Setting configuration parameters.
Recommended configuration parameters for first-time use.
PAR. DEF. PARAMETER
SP 0.0 setpoint
P0 2 type of probe

4. Disconnect the device from the mains.
5. Make the electrical connection as shown in the section ELECTRICAL CONNECTION
without powering up the device.
6. When connecting to an RS-485 network, connect the EVIF22TSX interface; see the
relative instruction sheets.
Universal controllers with one regulation output for industrial applications
7. Power up the device.
