1 MEASUREMENTS AND INSTALLATION

Measurements in mm (inches). 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.

2 ELECTRICAL CONNECTION

N.B.

- Use cables of an adequate section for the current running through them.

- To reduce any electromagnetic interference connect 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, the 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 doing any type of maintenance.

- Do not use the device as safety device.

- For repairs and for further information, contact the EVCO sales network.

3 FIRST-TIME

1. Install following the instructions given in the section MEASUREMENTS AND INSTALLATION.

2. Power up the device as shown in the section ELECTRICAL CONNECTION and an internal test will be run.

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 MIN... MAX. SP 0.0 setpoint r1... r2 P0 1 probe type 0 = PTC 1 = NTC P2 0 temperature unit of measurement 0 = °C 1 = °F

Then check that the remaining settings are appropriate; see the section CONFIGURA-

TION PARAMETERS.

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. For the connection in an RS-485 network connect the interface EVIF22TSX or EVIF23TSX, to activate real time functions connect the module EVIF23TSX (or use EV3... XRS); see the relevant instruction sheets.

7. Power up the device.
