DESCRIPTION

The EVD ice driver for electronic expansion valves with a unipolar stepper motor is a PID controller that manages the superheat of the refrigerant. The resin finish with plastic ensures IP67 protection, as well as protecting the controller against the cold/humid environment inside the cold room. The display can be used for simply configuring and commissioning the driver. The driver can also be configured from a computer, using the CAREL VPM software (Visual Parameter Manager), available at http://ksa.carel.com. The driver can be connected to a CAREL pCO series controller via serial link, to a CAREL supervisor, or to the cold room control Ultracella.

DIMENSIONI – mm(in)

*()** for standard CAREL codes.

MOUNTING

Important:

• INSTALL THE CONTROLLER IN THE EVAPORATOR UNIT, AWAY FROM POINTS WHERE FROST FORMS
• make the power cable and serial cable connections in the IP65 junction box
• to install the E2V/E3V valve, see the “ExV Sistema” guide, +030220811

Mark the position of the holes on the wall inside the evaporator unit, as shown in the figure, and drill the holes (Ø<4.5 mm).
Then tighten the fastening screws.

KEYPAD

• Increases/decreases the value of the setpoint or other selected parameter
• At the end of the first the commissioning procedure, if pressed for 2 seconds, exits the menu, and regulation starts;
• Enter/ exit programming mode, with parameters saving;
• Reset the E8 alarm

DISPLAY

During operation, the display shows the superheat value or any alarms (see Alarm table).![CAREL EVDM011S5 Driver For Unipolar Electronic Expansion Valve

• Procedure](https://manuals.plus/wp-content/uploads/2022/04/CAREL-EVDM011S5 -Driver-For-Unipolar-Electronic-Expansion-Valve-Procedure-550x318.png)

The decimal point in the digit on the right displays the start/stop regulation status.
When the inpunt is closed, the point is ON blinking.

FIRST COMMISSIONING

Important:

1. as long as the first commissioning procedure is not completed, the regulation is not active;
2. the change of refrigerant involves the change in the type of pressure ratiometric probe.

Power ON the driver: the display will be light and the driver is waiting for the first commissioning parameters, shown by the display bar:

• Refrigerant (default=3: R404A)
• Type of control (default = 1: multiplexed showcase/cold room
• Superheat set point (default: 11 K)

Procedure:

1. The display shows the top bar: refrigerant (GAS Type):
   

2. Press PRG/Set: the refrigerant setting is shown
   

3. Press UP/Down to change the value
   

4. Press PRG/Set to save and return to the refrigerant parameter code (bar at the top).

5. Press DOWN to move to the next parameter: Mode, indicated by the bar in the middle

6. Repeat steps 2, 3, 4, 5 to set the values of the other parameters: Mode, Superheat set point
   

7. Press PRG/Set for 2 seconds to exit the commissioning procedure and activate the regulation. The display returns to standard visualization (superheat measure).

PARAMETERS FIRST CONFIGURATION

Gas Type Refrigerant (default = 3).
Important: ONLY DURING THE FIRST COMMISSIONING PROCEDURE the gas change involves the change of the value of the ratiometric probe parameter; if not specified in the table the ratiometric probe is (-1…9.3 barg) type.

Mode (default = 1)
0: The regulation mode is set to 0 when one of the following parameters is changed: PID proportional gain, PID integral time, low superheat integral time, LOP integral time, and MOP integral time.
1: Centralized cabinet-cold room
2: AC or chiller with plate evaporator
3: AC or chiller with shell tube evaporator
4: AC or chiller with battery coil evaporator

INSTALLATION

Installation warnings:

1. all installation and maintenance operations must be performed with the driver not powered;
2. avoid short-circuits between pins L, N.
   • The EVD ice controller is integrated into an appliance, do not use for wall mounting.
   • DIN VDE 0100: protective separation must be guaranteed between the SELV circuits and the other circuits.

Inputs and outputs
It is recommended to keep the input/output and relay cables separate from the valve power cable. All the analog inputs and the serial ports (not optically isolated) refer to GND, and consequently applying, even temporarily, voltages greater than ±5 V to these connections may cause irreversible damage to the driver.
First start-up
Power on the driver, the display will come on and when starting for the first time, will guide the installer through the entry of the 3 parameters required to start operation: refrigerant type, type of control, superheat set point.
Important: the majority of refrigerants matches with the ratiometric pressure probe SPKT0013P0 (-1…9.3 barg). For installation with other ratiometric pressure probes, see the EVD ice manual, cod. +0300038EN, available for download at www.carel.com, even prior to purchase.
