1. GENERAL WARNING
1.1 PLEASE READ BEFORE USING THIS MANUAL
3.3.5 Neutral zone regulation
With oA1 = db the relay 1-7 can control a heater element to perform a neutral zone action.
oA1 cut in = SET-HY
oA1 cut out = SET
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.
3.3.6 Alarm relay
With oA1 = ALr the relay 1-7 operates as alarm relay. It is activated every time an alarm happens. Its
status depends on the tbA parameter: if “tbA = y”, the relay is silenced by pressing any key.
If “tbA = n”, the alarm relay remains on until the alarm condition recovers.
1.2
SAFETY PRECAUTIONS
Check the supply voltage is correct before connecting the instrument.
3.3.7 Night blind management during energy saving cycles
With oA1 = HES, the relay 1-7 operates to manage the night blind: the relay is energised when the
energy saving cycle is activated , by digital input, frontal button or RTC (optional)
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.r.l.” (see
address) with a detailed description of the fault.
4. FRONT PANEL COMMANDS
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 XR35CH, format 32 x 74 mm, is a digital thermostat with off cycle defrost designed for
refrigeration applications at normal temperature. It provides two relay outputs, one for the compressor,
the other one can be used as light, for alarm signalling or as auxiliary output.. It could be provided with
a Real Time Clock which allows programming of up to 6 daily defrost cycles, divided into holidays and
workdays. A “Day and Night” function with two different set points is fitted for energy saving. It is also
provided with up to four NTC or PT1000 probe inputs, the first one for temperature control, the second
one, to be located onto the evaporator, to control the defrost termination temperature. One of the 2
digital inputs can operate as third temperature probe. The fourth probe is used to signal the condenser
temperature alarm or to display a temperature.
: To display target set point; in programming mode it selects a parameter or confirm an
operation.
(DEF) To start a manual defrost
(UP): To see the max. stored temperature; in programming mode it browses the parameter
codes or increases the displayed value.
(DOWN) To see the min stored temperature; in programming mode it browses the parameter
codes or decreases the displayed value.
The RS485 serial output allows to connect the unit to a network line ModBUS-RTU compatible such
as the dIXEL monitoring units of X-WEB family. The HOT key receptacle allows to program the
controller by means the HOT KEY programming keyboard.
To switch the instrument off, if onF = oFF.
The instrument is fully configurable through special parameters that can be easily programmed
through the keyboard.
