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.
Dixell Srl reserves the right to change the composition of its products, even without
notice, ensuring the same and unchanged functionality.
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.
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.” 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; do not use the same electrical
conduit to install high voltage cabling and low voltage cabling.
The ground connection of the secondary coil of the transformer that powers the device
can result in a bad performance; where possible, this connection should be avoided.
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.
The symbol alerts the user of non-insulated “dangerous voltage” within the
product area that is sufficiently high to constitute a risk of electric shock to persons.
The symbol alerts the user of important operating and maintenance
(assistance) instructions found in the documentation attached to the device.
1592022760 Quick reference guide iCHILL 200CX EVO rel. 1.0 6/40
1.3 PRODUCT DISPOSAL (WEEE)
With reference to Directive 2002/96/EC of the European Parliament and of the Council
of 27 January 2003 and to the relative national legislation, please note that:
There lies the obligation not to dispose of electrical and electronic waste as
municipal waste but to separate the waste.
Public or private collection points must be used to dispose of the goods in
accordance with local laws. Furthermore, at the end of the product's life, it is
also possible to return this to the retailer when a new purchase is made.
This equipment may contain hazardous substances. Improper use or
incorrect disposal can have adverse effects on human health and the
environment.
The symbol shown on the product or the package indicates that the product
has been placed on the market after 13 August 2005 and must be disposed
of as separated waste.
Should the product be disposed of incorrectly, sanctions may be applied as
stipulated in applicable local regulations regarding waste disposal.

15 BLACK-OUT
After the black-out, when the power supply is restored:
1. the instrument restores the same operating mode lost after the supply failure.
2. if active at the power off, the defrost is aborted
3. All the timers are reloaded
4. The alarm, if actives in manual mode at the power down, is not reset

1592022760 Quick reference guide iCHILL 200CX EVO rel. 1.0 26/40
16.1 REMOTE KEYBOARD CONNECTION
It is possible to connect to the instrument up to two remote terminals VICX620 EVO, available with /
without temperature probe on board, or an LCD keyboard Visograph 2.0 (V2I820 without probes on
board); the use of keyboards VICX620 EVO exclude the possibility of use of the keyboard Visograph
and vice versa.
If the remote terminal VICX620 EVO is provided with temperature sensor on board, the temperature
adjustment can be performed with the probe at the edge of the terminal.
To enable the remote keyboard is necessary to configure the following parameters (in the Ichill
parameter map):
• CF54 Enable remote terminal 1 (VICX620 EVO)
• CF55 Enable remote terminal 2 (VICX620 EVO)
• CF84 Enable remote terminal Visograph (V2I820)
The connection of the remote terminals must be performed using a shielded / twisted (such as Belden
8772, wires 1 mm2 minimum); the maximum distance is 100M (maximum length of the connection,
both if using one or two keyboards).
In case of lack of communication between the device and the keyboard (wrong connection, wrong
configuration parameters), the display shows the message "noL" (no link).
When using two keyboards VICX620 EVO you must configure the dip switches on the rear of the
same, giving to the first keyboard address 1 and to the second keyboard address 2.
