Installation and Operating Instructions

UNIVERSAL–XR60CX

1. GENERAL DESCRIPTION

Model Universal-XR is a 71x29 mm format microprocessor based controller, 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.

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.

• 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).

Installation and Operating Instructions

Table 1: parameter “tC” settings

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

4. PARAMETER TABLE and factory default settings

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 program ming the
parameters will be changed back to the default listed below.

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

Table 4: controller parameters in detail

Display visualisation

Description

TC

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

PBC

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

HY

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.

LS

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

US

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

AC

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

ACI

Second compressor start delay: (0 to 255sec)

ALP

Probe selection for temperature alarms

0=P1, Room Probe
1=P2, Evaporator Probe
2=P3, Display Probe
3=P4, Hot Key Connector Probe, Condenser Alarm Probe

ALC

Temperature alarm configuration:
rE = Related to Set Point;
Ab = Absolute.
Note: Relative means alarms are linked to the Set Point and will follow it if it is adjusted. In this case ALU & ALL set the temp over & under Set Point for alarm. Absolute means
ALU & ALL are fixed alarm temperatures, which are not affected by any Set Point adjustment.

ALU

High temperature alarm:

ALC = rE→ [0 to 50°C] or [0 to 90°F];
ALC = Ab → [ALL to 150°C] or [ALL to 302°F].

ALL

Low temperature alarm:

ALC = rE → [0 to 50°C] or [0 to 90°F];
ALC = Ab → [-55°C to ALU] or [-67 to ALU].

AFH

Differential for alarm recovery, the control will still display the alarm until this value+

ALD

Temperature alarm delay: (0 to 255min) time interval between an alarm condition occurring and the alarm is signalling.

DAO

Delay of temperature alarm at start-up: (from 0 to 720min; res. 10min) time delay of any temperature alarm during pull down following “power on”.

ODS

Outputs activation delay at start up: (0 to 255min) time delay before any output relay activates following “power on”.

CCT

Thermostat override: (0 to 990min; res. 10min) period during which the compressor will run continuously, regardless of temperature. Setting this parameter to 0 disables this
function.

CCS

Set point for continuous cycle: (-55 to 150 °C or -67 to 302°F) it sets the set point used during the continuous cycle.

DAF

Defrost delay after fast freezing: (0 to 255min) time interval between the end of the thermostat override period and the start of the following defrost related to it.

IDF

Interval between defrosts: (0 to 255hours) time interval between the beginning of two consecutive defrosts.
