DIGITAL INPUTS POLARITY
The digital input polarity depends on the “I2P” parameters.
CL : the digital input is activated by closing the contact.
OP : the digital input is activated by opening the contact
7.
INSTALLATION AND MOUNTING
Instruments 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).
Instruments XW10V shall be mounted on vertical panel, in a 72x56 mm hole, and fixed using screws
∅
3 x 2mm. To obtain an IP65 protection grade use the front panel rubber gasket (mod. RGW-V).
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.

ELECTRICAL CONNECTIONS
The instruments are provided with screw terminal block to connect cables with a cross section up to 2,5
mm
2
for the digital and analogue inputs. Relays and power supply have a Faston connection (6,3mm).
Heat-resistant cables have to be used. Before connecting cables make sure the power supply complies
with the instrument’s requirements. Separate the probe cables from the power supply cables, from the
outputs and the power connections. Do not exceed the maximum current allowed on each relay, in case
of heavier loads use a suitable external relay.
N.B. Maximum current allowed for all the loads is 20A.
8.1
PROBE CONNECTIONS
The probe shall be mounted with the bulb upwards to prevent damages due to casual liquid infiltration.
It is recommended to place the thermostat probe away from air streams to correctly measure the
average room temperature..

USE OF THE PROGRAMMING “HOT KEY “
The Wing units can UPLOAD or DOWNLOAD the parameter list from its own E2 internal memory to the
“Hot Key” and vice-versa.
9.1
DOWNLOAD (FROM THE “HOT KEY” TO THE INSTRUMENT)
1.
Turn OFF the instrument by means of the ON/OFF key, remove the TTL serial cable if present,
insert the “Hot Key” and then turn the Wing ON.
2.
Automatically the parameter list of the “Hot Key” is downloaded into the Wing memory, the
“DoL” message is blinking. After 10 seconds the instrument will restart working with the new
parameters.
3.
Turn OFF the instrument remove the “Hot Key”, plug in the TTL serial cable, then turn it ON
again.
At the end of the data transfer phase the instrument displays the following messages:
“end “ for right programming. The instrument starts regularly with the new programming.
“err” for failed programming. In this case turn the unit off and then on if you want to restart the
download again or remove the “Hot key” to abort the operation.
9.2
UPLOAD (FROM THE INSTRUMENT TO THE “HOT KEY”)
1.
Turn OFF the instrument by means of the ON/OFF key and remove the TTL serial cable if
present; then turn it ON again.
2.
When the Wing unit is ON, insert the “Hot key” and push
o
key; the "uPL" message
appears.
3.
Push “SET” key to start the UPLOAD; the “uPL” message is blinking.
4.
Turn OFF the instrument remove the “Hot Key”, plug in the TTL serial cable, then turn it ON
again.
At the end of the data transfer phase the instrument displays the following messages:
“end “ for right programming.
“err” for failed programming. In this case push “SET” key if you want to restart the programming again
or remove the not programmed “Hot key”.

ALARM SIGNALS
Message Cause
Outputs
“P1”
Thermostat probe failure
Alarm output ON; Compressor output according to
parameters “COn” and “COF”
“HA”
Maximum temperature alarm
Alarm output ON; Other outputs unchanged
“LA”
Minimum temperature alarm
Alarm output ON; Other outputs unchanged
“EE” Data or memory failure
Alarm output ON; Other outputs unchanged
“dA”
Door switch alarm
Alarm output ON; Other outputs unchanged
“EAL” External alarm
Alarm output ON; Other outputs unchanged
“BAL” Serious external alarm
Alarm output ON; Other outputs OFF
“PAL” Pressure switch alarm
Alarm output ON; Other outputs OFF
The alarm message is displayed until the alarm condition is recovery.
All the alarm messages are showed alternating with the room temperature except for the “P1” which is
flashing. To reset the “EE” alarm and restart the normal functioning press any key, the “rSt” message is
displayed for about 3s.
10.1
SILENCING BUZZER
Once the alarm signal is detected the buzzer can be silenced by pressing any key.
10.2
“EE” ALARM
The
dIXEL
instruments are provided with an internal check for the data integrity. Alarm “EE” flashes
when a failure in the memory data occurs. In such cases the alarm output is enabled.
