1. GENERAL WARNING
1.1 PLEASE READ CAREFULLY BEFORE USING THE DEVICE
This manual is an integral part of the product and should be kept near the instrument for
easy and quick reference.
The regulator should not be used in applications different from those described below.
Moreover, it can not be used as a safety device.
Before proceeding check carefully the limits of application.
Dixell Srl reserves the right to change the composition of its products, even without notice,
ensuring the same and unchanged functionality.
1.2 SAFETY INSTRUCTIONS
Check the supply voltage 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 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.
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
2. GENERAL DESCRIPTION
The XC35CX is a regulator for tandem condensing units. It can drive inverter-controlled
compressors, digital compressors or standard ON-OFF compressors. It is equipped with:
1 or 2 relay outputs to drive ON-OFF compressors of ventilators, or for alarm signalling;
1 TRIAC output for ventilator speed modulation in phase-cut mode (MAX current 2.2 A)
1 analogue output (0-10Vdc or PWM type) for electronic ventilators control, inverter
management or proportional repeater
Up to 3 digital inputs free of voltage for external alarm management
2 analogue inputs to be used with ratiometric pressure transducer (0-5Vdc)
Up to 4 temperature probe inputs NTC10k, NTC86k or PT1000 type
On the other side, the XC15CX differentiates itself by having only a 16 A relay. All functionalities
described in the following manual are common for both XC15CX and XC35CX (with the only exception
of function related to second 5 A relay).
