Dixell UNIVERSAL–XR Installation Manual

UNIVERSAL–XR Unit of Measure Change Instructions

STEP 1

Install the new Universal-XR per the installation instructions included with the controller.

STEP 2

Turn on power,

THEN WITHIN 1 MINUTE COMPLETE STEPS 3, 4 AND 5.

STEP 3

+

Press the “SET” and “DOWN” key for 3 seconds and the controller will automatically recognise and
adjust itself to the type of probes connected. (The display briefly shows tPd followed by ntC or PtC).

STEP 4

Press the “AUX/tC” key for 3 seconds and the setting of parameter tC is displayed. Use the UP or
DOWN keys to adjust to required setting then confirm by pressing SET (see table 1 below).

STEP 5

Press SET for 3 seconds until the °C or °F icon starts to flash, then adjust the SET POINT using the UP
or DOWN keys, then press SET again to confirm.

1. GENERAL DESCRIPTION

Model Universal-XR is a 71x29 mm format microprocessor based controller, it is available in 12/24Vac/dc, 120Vac or
230Vac,and is suitable for applications on high, medium or low temperature refrigeration units. It is provided with three relay
outputs to control compressor, defrost - which can be both electrical or hot gas - and evaporator fans. It can work with PTC
or NTC probes. Where defrost is being terminated by time, it can operate with just one thermostat probe. Where defrost is
being terminated by temperature, it has an input for an evaporator probe(s).
The Universal-XR is equipped with a flashing visual alarm and buzzer.
Each instrument is fully configurable through special parameters that can be easily programmed through the keypad.

2. QUICK START UP PROCEDURE – Up and running in 5 easy steps

This Quick Start Up section is designed to get you up and running with the minimum of fuss. Just follow these 5 simple steps.

 Notes:

1. All probes must be of the same type, either PTC or NTC.

2. Probes must be at between --58 to 140°F for auto recognition to work;

3. If 1 minute expires before you have completed quick set up, either cycle the power OFF then ON to start the set up again or
enter Pr2 as per the instructions and adjust your parameter settings manually (see Section 9).

Note: As you change parameter tC, defaults change and should be approximately correct for that application but we strongly recommend you check

all parameter default values listed in these instructions to ensure they suit your particular application and make further adjustments if necessary. Read
the following sections for information about programming.

WARNING!!
Always switch the power OFF and then ON at the end of programming to update any parameter changes.
Make sure you connect the correct number of probes to suit the setting of parameter tC. Failure to do this will cause probe alarms

IMPORTANT: Always set parameter “tC” first. As you move “tC” between settings 1 to 7, all non-relevant parameters will be masked. After setting
“tC”, it will be possible to modify all the other relevant parameters.

Once the program is completed you may want to save the parameter map to a Hot Key. If the “tC” is changed after final programming the
parameters will be changed back to the default listed below.

Description

Type of Controller: tells the Universal-XR which type of controller it will be operating as.

1 = on/off Heating thermostat – 1 relay & 1 probe;
2 = Combined thermostat with off cycle defrost timer – 1 relay & 1 probe;
3 = Combined thermostat with time initiated & time terminated defrost – 2 relays & 2 probe;
4 = Combined thermostat with time initiated & temperature terminated defrost – 2 relays & 2 probes; alarm
5 = Combined thermostat with time initiated, temperature terminated defrost + 2 relays & 2 probes; defrost
6 = Combined thermostat with time initiated, temperatures terminated defrost + evaporator fans control with delay after defrost – 3 relays & 3 probes;
7 = Combined thermostat with time initiated, temperatures terminated defrost + evaporator fans control with delay after defrost – 3 relays & 3 probes. Fully open map

Probe Type: configures the controller to work with PTC or NTC probes.
0= ptC = PTC,
1= ntC = NTC.

Differential: (1 to 50) sets the degrees above Set Point at which the compressor cuts in.
Note: when tC = 1 (heating applications) the tC value is automatically set below the Set Point. If the temperature decreases and reaches set point minus differential the regulation output is activated and

then turned off when the temperature reaches the set point value again.

Minimum set point limit: (-55°C to SET or -67°F to SET) sets the lower limit of set point adjustment.

Maximum set point limit: (SET to 150°C or SET to 302°F) sets the upper limit of set point adjustment.

Anti-short cycle delay: (0 to 50min) minimum interval between the compressor stop and the next possible restart.
