MEASUREMENTS AND INSTALLATION

Measurements in mm inches. To be fitted to a panel, snap-in brackets provided EVCO EV3294 Controllers and Displays logo 2

EVCO EV3294 Controllers and Displays logo 3

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.
  • To reduce any electromagnetic interference connect the power cables as far away as possible from the signal cables.

EVCO EV3294 Controllers and Displays logo 4PRECAUTIONS 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. 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.

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.
  3. The test normally takes a few seconds, when it is finished the display will switch off.
  4. Configure the device as shown in the section Setting configuration parameters.
  5.  Recommended configuration parameters for first time use.

d1 0 defrost type 0 = electric

1 = hot gas

2 = compressor stopped

Then check that the remaining settings are appropriate.

  • Disconnect the device from the mains.
  • Make the electrical connection as shown in the section ELECTRICAL CONNECTION without powering up the device.
  • For the connection in an RS-485 network connect the interface EVIF22TSX or EVIF23TSX, to activate real time functions connect the module EVIF23TSX, to use the
    device with the APP EVconnect connect the interface EVIF25TBX or use EV3… XRV.
  • To use the device with the EPoCA remote monitoring system, connect the EVIF25TWX module; see the relevant instruction sheets.
  • EVIF22TSX or EVIF23TSX is used, set parameter bLE to 0.
  • Power up the device.
