1 GENERAL ADVICE
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.
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.
• The instrument must not be opened.
• In case of failure or faulty operation send the instrument back to the distributor or to “Dixell s.r.l.”
(see address) with a detailed description of the fault.
• Consider the maximum current which can be applied to each relay (see thechnical Data).
• Ensure that the wires for probes, loads and the power supply are separated and far enough from
each other, without crossing or intertwining.
• Fit the probe where it is not accessible by the end user.
• In case of applications in industrial environments, the use of mains filters (our mod. FT1) in parallel
with inductive loads could be useful.

push SET, check the led.
Example in fig.1
Icon Cir1 is on: the top display shows the value of the output evaporator temperature (12.8°C) of the
circuit 1; the bottom display shows Out 1 (outlet temperature evaporator 1). Push SET key to swap to
the circuit 2. Fig2

9 PROGRAMMING WITH THE “HOT KEY 64”
9.1 DOWNLOAD: HOW TO PROGRAM AN INSTRUMENT WITH A
PROGRAMMED “HOT KEY”
1. Turn off the instrument supply
2. Insert the hot key.
3. Turn on the power supply.
4. Immediately the parameters are downloaded.
During the download the regulation is locked and the top display shows the “doL” blinking label. At the
end of the download will appear:
1592022750 Quick reference guide IC 200CX Rel. 1.1 25/05/2009
“End” if the programming procedure is completely OK, after 30seconds the regulation starts
automatically.
“Err” if the programming procedure has found an error and the parameter have not been transferred.
In this case turn off and then on the instrument supply to repeat the operation or remove the hot key,
with power supply off, to restart the regulation.
9.2 UPLOAD: HOW TO PROGRAM A “HOT KEY” WITH THE
PARAMETERS OF THE INSTRUMENT
1. Turn on the power supply.
2. Insert the hot key.
3. Enter the function Menu.
4. Select the UPL function (on the bottom display).
5. Push SET key and immediately the instrument starts transfer the parameters into the Hot key.
During the upload the regulation is locked and the top display shows the “UPL” blinking label. At the
end of the UPLOAD will appear:
“End” if the programming procedure is completely OK, after 30seconds the regulation starts
automatically.
“Err” if the programming procedure has found an error and the parameter have not been transferred.
Repeat the procedure.
To exit the UPL function push the MENU key or wait the time-out.
10 PROGRAMMING USING THE KEYBOARD
Through the instrument keyboard it is possible to enter the programming. In all the three accessible
levels the user can show and modify both value and visibility of the parameters. To ensure an easy
navigation through the different levels the common parameters have been named and grouped under
a family name.
The three levels of programming:
• Pr1 User level
• Pr2 Maintenance level
• Pr3 OEM level
10.1 PASSWORD DEFAULT VALUES
• Password level Pr1 = 1
• Password level Pr2 = 2
• Password level Pr3 = 3
Each password can be changed, the range is from 0 to 999.
10.2 ENTER THE PR1 - PR2 - PR3 PROGRAMMING LEVELS
Pr1 LEVEL:
Push SET + DOWN together for 3 seconds, the top display shows the PAS label and the bottom
display shows the Pr1 label. The leds Cir1 and Cir2 are blinking to inform that you now are in PR1
programming level.
Pr2 LEVEL:
Starting from Pr1 level push the UP key for 2 seconds and the bottom display will show Pr2. The top
display still shows PAS.
Push the SET key and the top display will show the 0 blinking value; set the password level using the
UP and DOWN keys then confirm with SET key.
Pr3 LEVEL:
1592022750 Quick reference guide IC 200CX Rel. 1.1 25/05/2009
Pag. 20/58
Starting from the Pr2 level push the UP key for 2 seconds and the bottom display will show Pr3. The
top display still shows PAS.
After selecting the level push the SET key and the top display will show the 0 blinking value where to
insert the password.
Set the password level using the UP and DOWN keys then confirm with SET key.
Dependening on the password value there will be the different level access, if the password is wrong
the instrument shows the password value again.
ATTENTION:
For all the programming levels Pr1, 2, 3: the CF family (or configuration parameters) can not be
changed if the unit is running in chiller or heat pump. To change this parameters is necessary
to set the unit in stand-by and then enter the programming again.
During the defrost the dF family can’t be programmed.
10.3 HOW TO CHANGE A PARAMETER VALUE
Enter the programming
1. Push the SET + DOWN keys together for 3 seconds;
2. Select the parameter label with up and down keys;
3. Push SET to enter the parameter value;
4. Change the value with UP or DOWN keys;
5. Push “SET” to confirm, after some seconds the display shows the next parameter;
6. Exit: Push SET + UP together when a parameter label is displayed or wait 15seconds without
pushing a key.
NOTE: a new parameter value is confirmed also after the 15 seconds of timeout is expired (without
pushing SET key to confirm).
10.4 CHANGE THE PASSWORD VALUE
Pr1 LEVEL
Remember that it is necessary to know the old password value.
1) Enter the Pr1 level
2) Select a parameter family.
3) Select “Pr1” on the bottom display; the current password value is on the top display. Push the
SET key to change the value that now is blinking.

16 INSTALLING AND MOUNTING
16.1 PANEL CUT- OUT
The instrument must be mounted on vertical panel, with panel cut-out 71x29mm, and fixed using the
special bracket supplied.
Avoid locations subject to heavy vibration, corrosive gases or excessive dirt. Ensure ventilation around
the instrument.
16.2 VERTICAL BOARDS VI620CX PANEL CUT-OUT
The remote terminals are for panel mounting, panel cut-out 72x56 mm, and screwed with two screws.
The IP65 can be reached with the gasket RGW-V (optional).
1592022750 Quick reference guide IC 200CX Rel. 1.1 25/05/2009
WALL MOUNTING: use the vertical V-KIT (black, white and grey) as described in the following
scheme:
17 ELECTRICAL CONNECTIONS
The instrument is provided with:
• 2 removable terminal blocks MOLEX MICROFIT 14 and 18 ways for power supplay / digital and
analogue inputs and modulating outputs
• 1 removable terminal blocks AMP 12 ways for the relay outputs
• 5 ways connector for TTL RS485 interface outputs.
Wire size:
1592022750 Quick reference guide IC 200CX Rel. 1.1 25/05/2009
• signal cable AWG 24

General notes:
• Check the connecitons and the line voltage before turning on the power supply.
• Keep low voltage cables, such as analogue/digital inputs/outputs and probes, away from power
cables and terminals.
• Respect the maximum load current of each relay output, in case of power loads use filtered
contactors.
