DIGITAL INPUTS  

The first digital input 13-14 is enabled  with P3P = n. 
With P3P = n and i1F = i2F the second digital input is disabled 
The free voltage digital inputs are programmable by the “i1F” and i2F  parameters. 

8.1

 

GENERIC ALARM (i1F or i2F = EAL) 

As soon as the digital input is activated the unit will wait for “did” time delay before signalling the 
EAL” alarm message. The outputs status don’t change. The alarm stops just after the digital input is 
de-activated. 

8.2

 

SERIOUS ALARM MODE (i1F or i2F =  bAL) 

When the digital input is activated, the unit will wait for “did” delay before signalling the “CA” alarm 
message. The relay outputs are switched OFF. The alarm will stop as soon as the digital input is de-
activated. 

8.3

 

PRESSURE SWITCH (i1F or i2F = PAL) 

If during the interval time set by “did” parameter, the pressure switch has reached the number of 
activation of  the “nPS” parameter, the “CA” pressure alarm message will be displayed. The 
compressor and the regulation are stopped. When the digital input is ON the compressor is always 
OFF.  If the nPS activation in the did time is reached, switch off and on the instrument to 

restart normal regulation. 

8.4

 

DOOR SWITCH INPUT  (i1F or i2F = dor) 

It signals the door status and the corresponding relay output status through the “odc” parameter: no, 
Fan = normal (any change); CPr, F_C = Compressor OFF. 
Since the door is opened, after the delay time set through parameter “did”, the door alarm is 
enabled, the display shows the message “dA” and the regulation restarts is rtr = yES. 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. 

8.5

 

SWITCH THE AUXILIARY RELAY (i1F or i2F = AUS) 

With oA3 = AUS the digital input switched the status of the auxiliary relay 

8.6

 

INVERSION OF  THE KIND OF ACTION: HEATING-COOLING (i1F or 

i2F=Htr)  

This function allows to invert the regulation of the controller: from cooling to heating and viceversa. 

8.7

 

ENERGY SAVING (i1F = ES) 

The Energy Saving function allows to change the set point value as the result of the SET+ HES 
(parameter) sum. This function is enabled until the digital input is activated. 

8.8

 

ON OFF FUNCTION (i1F or i2F = onF)  

To switch the controller on and off. 

8.9

 

DIGITAL INPUTS POLARITY  

The digital input polarity depends on the “i1P” and “i2P” parameters. 
i1P or i2P =CL: the input is activated by closing the contact. 
i1P or i2P=OP
: the input is activated by opening the contact 

9.

 

TTL SERIAL LINE – FOR MONITORING SYSTEMS 

The TTL serial line, available through the HOT KEY connector, allows by means of the external 
TTL/RS485 converter, XJ485-CX, to connect the instrument to a monitoring system ModBUS-RTU 
compatible  such as the  X-WEB500/3000/300. 

10.

 

X-REP OUTPUT – OPTIONAL 

As optional, an X-REP can be connected to the instrument, trough the dedicated 
connector. 

 

 

To connect the X-REP to the 
instrument the following 
connectors must be used 
CAB/REP1(1m), CAB/REP2 
(2m), CAB/REP5 (5m), 

11.

 

INSTALLATION AND MOUNTING 

The controller XW10L, shall be mounted on vertical panel, in a 150x31 mm hole, and fixed using two 
screws 

 3 x 2mm. To obtain an IP65 protection grade use the front panel rubber gasket (mod. RG-

L). The temperature range allowed for correct operation is 0 - 60 °C. Avoid places subject to strong 
vibrations, corrosive gases, excessive dirt or humidity. The same recommendations apply to probes. 
Let the air circulate by the cooling holes.
