1. GENERAL WARNING
1.1 PLEASE READ BEFORE USING THIS MANUAL
• This manual is part of the product and should be kept near the instrument for easy and
quick reference.
• The instrument shall not be used for purposes different from those described hereunder.
It cannot be used as a safety device.
• Check the application limits before proceeding.
1.2
SAFETY PRECAUTIONS
• Check the supply voltage is correct before connecting the instrument.
• Do not expose to water or moisture: use the controller only within the operating limits
avoiding sudden temperature changes with high atmospheric humidity to prevent
formation of condensation
• Warning: disconnect all electrical connections before any kind of maintenance.
• Fit the probe where it is not accessible by the End User. The instrument must not be
opened.
• In case of failure or faulty operation send the instrument back to the distributor or to
“Dixell S.p.A.” (see address) with a detailed description of the fault.
• Consider the maximum current which can be applied to each relay (see Technical Data).
• Ensure that the wires for probes, loads and the power supply are separated and far
enough from each other, without crossing or intertwining.
• In case of applications in industrial environments, the use of mains filters (our mod. FT1)
in parallel with inductive loads could be useful.
2. GENERAL DESCRIPTION
Model XR10C, format 32 x 74 mm format is a single stage temperature controller suitable for
applications in the field of refrigeration or heating. It provides a relay output to drive the
compressor. It is also provided with 2 NTC or PTC probe inputs, the first one for temperature
control, the second one, optional, to connect to the HOT KEY terminals to signal the
condenser temperature alarm or to display a temperature. The digital input can operate as
third temperature probe.
The HOT KEY output allows to connect the unit, by means of the external module XJ485-CX,
to a network line ModBUS-RTU compatible such as the dIXEL monitoring units of X-WEB
family. It allows to program the controller by means the HOT KEY programming keyboard.
The instrument is fully configurable through special parameters that can be easily
programmed through the keyboard.
3. CONTROLLING LOADS
3.1 THE REGULATION OUTPUT
The regulation is performed according to the temperature measured by the probe.
The instruments are provided with the CH programmable parameter which enables the user to
set the regulation both for heating or cooling applications:
· CH = CL: cooling applications
· CH = Ht: heating applications
3.2 CH = CL: COOLING APPLICATIONS.
The Hy value is automatically set above the Set Point. If the temperature increases and
reaches set point plus differential the compressor is started and then turned off when the
temperature reaches the set point value again.

rSE Real set point: (readable only), it shows the set point used during the energy saving
cycle or during the continuous cycle.
rEL Software release for internal use.
Ptb Parameter table code: readable only.
8. DIGITAL INPUT (ENABLED WITH P3P = N)
The free voltage digital input is programmable in different configurations by the “i1F”
parameter.
8.1 DOOR SWITCH INPUT (i1F = dor)
It signals the door status and the corresponding relay output status through the “odc”
parameter: no, Fan = normal (any change); CPr, F_C = Compressor OFF.
Since the door is opened, after the delay time set through parameter “did”, the door alarm is
enabled, the display shows the message “dA” and the regulation restarts is rtr = yES. The
alarm stops as soon as the external digital input is disabled again. With the door open, the
high and low temperature alarms are disabled.
8.2 GENERIC ALARM (i1F = EAL)
As soon as the digital input is activated the unit will wait for “did” time delay before signalling
the “EAL” alarm message. The outputs status don’t change. The alarm stops just after the
digital input is de-activated.
8.3 SERIOUS ALARM MODE (i1F = bAL)
When the digital input is activated, the unit will wait for “did” delay before signalling the “CA”
alarm message. The relay outputs are switched OFF. The alarm will stop as soon as the
digital input is de-activated.
8.4 PRESSURE SWITCH (i1F = PAL)
If during the interval time set by “did” parameter, the pressure switch has reached the number
of activation of the “nPS” parameter, the “CA” pressure alarm message will be displayed. The
compressor and the regulation are stopped. When the digital input is ON the compressor is
always OFF.
If the nPS activation in the did time is reached, switch off and on the instrument to
restart normal regulation.
8.5 INVERSION OF THE KIND OF ACTION: HEATING-COOLING (i1F = Htr)
This function allows to invert the regulation of the controller: from cooling to heating and
viceversa.
8.6 ENERGY SAVING (i1F = ES)
The Energy Saving function allows to change the set point value as the result of the SET+
HES (parameter) sum. This function is enabled until the digital input is activated.
8.7 DIGITAL INPUTS POLARITY
The digital input polarity depends on the “i1P” parameter.
i1P=CL: the input is activated by closing the contact.
i1P=OP: the input is activated by opening the contact
9. TTL SERIAL LINE – FOR MONITORING SYSTEMS
The TTL serial line, available through the HOT KEY connector, allows by means of the
external TTL/RS485 converter, XJ485-CX, to connect the instrument to a monitoring system
ModBUS-RTU compatible such as the X-WEB500/3000/300.
10. X-REP OUTPUT – OPTIONAL
As optional, an X-REP can be connected to the instrument, trough the HOY
KEY connector. The X-REP output EXCLUDES the serial connection.
To connect the X-REP to the
instrument the following
connectors must be used CAB51F(1m), CAB-52F(2m), CAB55F(5m),
11. INSTALLATION AND MOUNTING
Instrument XR10CX shall be mounted on vertical panel, in a
29x71 mm hole, and fixed using the special bracket supplied.
The temperature range allowed for correct operation is 0÷60
°C. Avoid places subject to strong vibrations, corrosive
gases, excessive dirt or humidity. The same
recommendations apply to probes. Let air circulate by the
cooling holes.
12. ELECTRICAL CONNECTIONS
The instrument is provided with screw terminal block to connect cables with a cross section up
to 2,5 mm2. Before connecting cables make sure the power supply complies with the
instrument’s requirements. Separate the probe cables from the power supply cables, from the
outputs and the power connections. Do not exceed the maximum current allowed on each
relay, in case of heavier loads use a suitable external relay.
12.1 PROBE CONNECTION
The probes shall be mounted with the bulb upwards to prevent damages due to casual liquid
infiltration. It is recommended to place the thermostat probe away from air streams to correctly
measure the average room temperature. Place the defrost termination probe among the
evaporator fins in the coldest place, where most ice is formed, far from heaters or from the
warmest place during defrost, to prevent premature defrost termination.
13. HOW TO USE THE HOT KEY
13.1 HOW TO PROGRAM A HOT KEY FROM THE INSTRUMENT (UPLOAD)
1. Program one controller with the front keypad.
2. When the controller is ON, insert the “Hot key” and push o key; the "uPL" message
appears followed a by flashing “End”
3. Push “SET” key and the End will stop flashing.
4. Turn OFF the instrument remove the “Hot Key”, then turn it ON again.
NOTE: the “Err” message is displayed for failed programming. In this case push again o key
if you want to restart the upload again or remove the “Hot key” to abort the operation.
13.2 HOW TO PROGRAM AN INSTRUMENT USING A HOT KEY
(DOWNLOAD)
1. Turn OFF the instrument.
2. Insert a programmed “Hot Key” into the 5 PIN receptacle and then turn the
Controller ON.
3. Automatically the parameter list of the “Hot Key” is downloaded into the Controller
memory, the “doL” message is blinking followed a by flashing “End”.
4. After 10 seconds the instrument will restart working with the new parameters.
5. Remove the “Hot Key”..
NOTE the message “Err” is displayed for failed programming. In this case turn the unit off and
then on if you want to restart the download again or remove the “Hot key” to abort the
operation.
