Brown wire (+) to terminal 18;

White wire (in) to terminal 20;

Green wire (gnd) to terminal 21

Temperature probe:

Set parameter

ttE = NTC: (NTC 10K) or

ttE = Pt1: (Pt1000) or

ttE = CtC: (NTC-US 10K)

4.6 CONFIGURABLE DIGITAL INPUT CONNECTION

The superheat regulation is performed only when the cooling digital input is enabled.

It’s possible to enable the SH regulation via:

- Digital input 1, free voltage contact:

Use the terminals (14-15), set the parameter i1F = CCL, its polarity it’s set by par. i1P.

- Digital input 2 (8-9), main voltage contact

Use the terminals (8-9), set the parameter i2F = CCL, its polarity it’s set by par. i1P

Usually the digital input is connected to a thermostat or an activation contact

T= Thermostat ( or activation contact)

V= Stepper valve (mono or bipolar)

P1= Temperature sensor (PT1000 o

NTC or NTC-US)

P2= Pressure transducer 4..20mA or

ratiometric (0-5Vdc).

4.7 SUPPLY CONNECTION

Power supply: XEV22D is powered at 24Vac/dc.

Use Class 2 transformer at list 20VA as the TF20D

Connect transformer to terminals 11-12.

4.8 VALVE CONFIGURATION

4.8.1 BEFORE CONNETTING THE VALVE

- ALWAYS CONNECT OR DISCONNET THE VALVE WHEN THE CONTROLLER IS NOT

POWERED

- CONFIGURE THE VALVE ON THE XEV22D BEFORE CONNECTING THE VALVE

1. BEFORE CONNECTING the valve, to avoid possible problems, configure the driver by making

the right changes on the parameters.

2. The max distance between an XM controller and a valve must not exceed 10 m. To avoid any

problems, use only shielded cables with section greater than or equal to 0.325 mm² (AWG22).

3. Select the kind of motor (tEU parameter) and check if the valve is present in tEP parameter

table reported here below.

In any case for each valve the only reference is given by the manual released by the manufacture

together with the valve.

Dixell can’t be considered responsible for any change made by the manufacturer and reported on the

manufacturer manual.

4.8.2 Manual setting of valve

To set the valve manually, act the according to the following procedure:

a. Set tEP=0

b. Then set following parameters: LSt, USt, Sr, CPP, CHd according to the valve manual

AFTER MAKING THE CONNECTION, PLEASE SWITCH OFF AND ON THE XEV CONTROLLER IN

ORDER TO BE SURE OF THE RIGHT POSITIONING OF THE VALVE.

4.10 ABSOLUTE MAXIMUM POWER

XEV22D is able to drive a wide range of stepper valves, in the following table are indicated the

maximum values of current that the actuator can supply to the stepper wiring. The Dixell transformer to

use is the TF20D.

NOTE: the electrical power absorption of the valve can be unrelated to refrigeration power that valve

has. Before using the actuator, please read the technical manual of the valve supplied by the

manufacturer and check the maximum current used to drive the valve in order to verify that they are

lower than those indicated below.
