1 MEASUREMENTS AND INSTALLATION | Measurements in mm (inches)
1.1 Models in plastic container
According to the model, front installation on a plastic or metal panel (with elastic holding flaps)
or installed from behind a glass or methacrylate panel (with biadhesive) customizing the keys
on the front of the unit.
N.B.
For models for front installation: the thickness of a metal panel must be between
0.8 and 1.5 mm (1/32 and 1/16 in), while that for a plastic panel must be between
0.8 and 3.4 mm (1/32 and 1/8 in).
For models installed from behind: the thickness of the panel must be between
2.0 and 4.0 mm (1/16 and 1/8 in); the panel and the material used to make screen
printing must not contain conductive substances.
1.2 Open-frame models
To be installed from behind, with threaded studs and membrane keypad.
INSTALLATION PRECAUTIONS
- 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 USE
1. Install following the instructions given in the section MEASUREMENTS AND
INSTALLATION.
2. Power up the device 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.

2 = compressor stopped
Then check that the remaining settings are appropriate; see the section
CONFIGURATION 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 in EVJ203, EVJ204, EVJ205, EVJ224 and
EVJ225 connect the module EVIF23TSX, for recording HACCP data in CSV format on SD
card connect the module EVBD05, to use the device with the Android APP EVconnect
connect the interface EVIF25TBX (or use EVJ214N7VXXRXV, EVJ234 or EVJ235); see
the relevant instruction sheets. If EVIF22TSX or EVIF23TSX is used, set
parameter bLE to 0.
7. Power up the device.
4 USER INTERFACE AND MAIN FUNCTIONS
4.1 Switching the device on and off
1.
If POF = 1 (default), touch the ON/STAND-BY key for 2s.
If the device is switched on, the display will show the P5 value ("cabinet temperature" default);
if the display shows an alarm code, see the section ALARMS.
