EN
dA Exclusion of temperature alarm at startup: (0÷99 min) time interval between the detection of the temperature alarm condition after instrument power
on and alarm signalling.
DIGITAL INPUT
iP Digital input polarity: (oP ÷ cL) oP= activated by closing the contact; cL= activated by opening the contact.
iF Digital input conguration: (EA/bA/do/dF/Au/Hc) EA= external alarm: “EA” message is displayed ; bA= serious alarm “CA” message is displayed;
do= door switch function; dF= defrost activation; Au= not used; Hc= inversion of the kind of action.
di Digital input delay: (0÷99 min) with iF= EA or bA delay between the detection of the external alarm condition and its signal ling.
With iF= do it represents the delay to activate the door open alarm.
dC Compressor and fan status when open door: (no/Fn/cP/Fc): no= normal; Fn= Fans OFF; cP= Compressor OFF; Fc= Compressor and fans OFF.
rd Regulation with door open: (n÷y) n= no regulation if door is opened; Y= when di is elapsed regulation restarts even if door open alarm is present.
o1 Conguration output 1 (dF/Fn/AL/Au/db): through it, it is possible to congure the function of the output 1.
OTHER
dE Display of probe 1: (read only) it allows to display the value of the probe 1.
di Display of probe 2: (read only) it allows to display the value of the probe 2.

rL Software release.
3. DIGITAL INPUTS
The free voltage digital input is programmable in different congurations by the “iF” parameter.
PRESSURE SWITCH FAILURE ALARM (iF=bA)
When the digital input is activated, the unit will wait for “di” delay before signalling the “CA” alarm message. The relay outputs are switched OFF. The alarm
stops as soon as the digital input is deactivated.
DOOR SWITCH (iF=do)
It signals the door status and the corresponding relay output status through the “dC” parameter: no= normal (any change); Fn= Fan OFF; cP= Compressor
OFF; Fc= Compressor and fan OFF. Since the door is opened, after the delay time set through parameter “di”, the door alarm is enabled, the display shows the
message “dA” . 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.
EXTERNAL ALARM (iF=EA)
As soon as the digital input is activated the unit will wait for “di” time delay before signalling the “EA” alarm message. The outputs status don’t change. The
alarm stops just after the digital input is deactivated.
START DEFROST (iF=dF)
It starts a defrost if there are the suitable conditions. After the defrost is nished, the normal regulation will restart only if the digital input is disabled otherwise
the instrument will wait until the “Md” safety time is expired.
INVERSION OF CONTROLLER ACTION (iF=Hc)
This function allows to invert the regulation of the controller: from cooling to heating and viceversa.
4. ALARM SIGNALLING
MESSAGE CAUSE OUTPUTS
"P1" Room probe failure Compressor output according to “Cy” e “Cn”
"P2" Evaporator probe failure Defrost end is timed
"HA" Maximum temperature alarm Outputs unchanged
"LA" Minimum temperature alarm Outputs unchanged
"EA" External alarm Outputs unchanged
"CA" Pressure switch failure alarm All outputs OFF
"dA" Door Open Loads according to “dC”
Ü
All the signals different from the ones specied in this manual indicate a serious damage to the electronic control panel.

ALARM RECOVERY
Probe alarms “P1” and “P2” go off some seconds after the fault in the related probe; they stop automatically some seconds after the probe restarts its nor-
mal operation. Check connections before replacing the probe. The Temperature alarms “HA” and “LA” stop automatically as soon as the temperature of the
thermostat returns to normal values and when a defrost starts. Alarms “EA” and “CA” (with iF=bL) are disabled as soon as the digital input is deactivated.
5. GENERAL DATA
The XR06CX instrument is provided with two NTC probe inputs, one for temperature control, the other, to be located into the evaporator, to control the defrost
termination temperature and to control the fan.
