• 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, locate the power cables as far away as possible from the signal cables
• the K3 and K4 relays are not available in models with 3 relays
• the K4 relay is not available in models with 4 relays
• port for remote indicator is only available in model EVYB35LN9VFT

PRECAUTIONS FOR ELECTRICAL CONNECTION

• if using an electrical or pneumatic screwdriver, adjust the tightening torque
• if the device is moved from a cold to a warm place, humidity may cause condensation to form inside. Wait for 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 a safety device
• for repairs and further information, contact the EVCO sales network

FIRST-TIME USE

1. Carry out the installation following the instructions given in the section MEASUREMENTS AND INSTALLATION.

2. Power up the device: 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:
   Next 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. To perform the configuration upload or download, connect the EVJKEY programming key.

   • To activate real-time functions, connect the EVlinking RS-485 EVIF23TSX converter.
   • To control the device using the EVconnect app, connect the EVlinking BLE EVIF25TBX module then synchronise it with the app.
   • To control the device using the EPoCA monitoring system or a third-party MODBUS TCP system:
   • connect the EVlinking Wi-Fi EVIF25TWX module to the device and then to a local Wi-Fi network
   • connect the EVlinking RS-485 EVIF24TSX converter to the device then to an IoT
   • EV3 Web gateway or EVD Web. Next connect this to a free Ethernet port of a router or an Ethernet hub connected to a local network.

7. Power up the device again.

USER INTERFACE AND MAIN FUNCTIONS

Switching the device on/off

1.  If POF = 1 (default), touch the ON/STAND-BY key for 4
   If the device is switched on, the display will show the P5 value (default “cabinet or product temperature”); if the display shows an alarm code, see the section ALARMS.

If Loc = 1 (default) and 30 s have elapsed without the keys being pressed, the display will show the “Loc” label and the keypad will lock automatically.

Unlocking the keypad
Touch a key for 1 s: the display will show the label “UnL”.

Setting the setpoint (if r3 = 0, default)
Check that the keypad is not locked.

Setting the 0-10 V evaporator fan speed for normal operation (percentage 0-10 V output; available if Ao1 = 3 and F30 = 0)
Check that the keypad is not locked.

Activating manual defrost (if r5 = 0, default)
Check that the keypad is not locked and that overcooling is not active

1. Touch the DEFROST key for 2 s

If P3 = 1 (default), defrost is activated provided that the evaporator temperature is lower than the d2 or d2b threshold.

Manually activating/deactivating the overcooling, overheating and energysaving functions

Check that the keypad is not locked.

1. Touch the DOWN key.

If u1c… u5c = 16, the evaporator fans will operate at this speed during the energy-saving function.
If u1c… u5c = 18, the condenser fans will operate at this speed during the energy-saving function.

Manually switching the cabinet light on/off (if u1c… u5c = 5)

1. Touch the CABINET LIGHT key

Switching the demisting function on (if u1c… u5c = 6)

1. Touch the CABINET LIGHT key (for 2 s if u1c… u5c = 5)
   The demisting function stays on for the duration of u6.

Switching auxiliary load 1 on/off (if u1c… u5c = 10)

1. Touch the CABINET LIGHT key (for 2 s if u1c… u4c = 5)

If u1c… u5c = 6, it also switches the demisting function on.

Switching auxiliary load 2 on/off (if u1c… u5c = 11)

1.  Touch the ON/STAND-BY key

Silencing the buzzer (if u9 = 1, default) Touch a key.
If u1c… u5c = 11 and u4 = 1, the alarm output is deactivated.

ADDITIONAL FUNCTIONS
Setting the date, time and day of the week (available when the EVlinking RS485 EVIF23TSX converter, the EVlinking BLE EVIF25TBX module or the EVlinking Wi-Fi EVIF25TWX module is connected)

Check that the keypad is not locked.

Activating the high or low humidity function (if F0 = 5)
Check that the keypad is not locked.

If u1c… u5c = 16, the evaporator fans will operate at this speed during low humidity function.

Viewing/deleting HACCP alarm information
Check that the keypad is not locked.

Example of alarm information (e.g. a high temperature alarm).

Viewing the minimum and maximum temperatures saved in the last 72 hours
Check that the keypad is not locked.

The device saves the rEt value (default “temperature of the cabinet or the product, not during defrost, pre-drip or dripping and with the fans off”).
When the device is switched on/off, these temperatures are deleted.

Viewing/deleting compressor operation days
Check that the keypad is not locked.
