)
Ld1÷Ld8 Workday defrost start
(0 ÷ 23h 50 min.) These parameters set the beginning of
the eight programmable defrost cycles during workdays. Ex. When
Ld2
= 12.4 the
second defrost starts at 12.40 during workdays.
Sd1÷Sd8 Holiday defrost start
(0 ÷ 23h 50 min.) These parameters set the beginning of
the eight programmable defrost cycles on holidays. Ex. When
Sd2
= 3.4 the
second defrost starts at 3.40 on holidays.
N.B. :
To disable a defrost cycle set it to “nu”(not used).
Ex.
If
Ld6
=nu
;
the sixth defrost cycle is disabled

DIGITAL INPUTS
The Wing series can support up to 2 free contact digital inputs. One is always configured
as door switch, the second is programmable in seven different configurations by the “
I2F
”
parameter.
7.1
DOOR SWITCH INPUT
It signals the door status and the corresponding relay output status through the “
odc
”
parameter:
no
= normal (any change);
Fan
= Fan OFF;
CPr
= Compressor OFF;
F_C
= Compressor and fan OFF.
Since the door is opened, after the delay time set through parameter “
dOA
”, the alarm
output is enabled and the display shows the message “
dA
”. The alarm stops as soon as
the external digital input is disabled again. During this time and then for the delay “
dot
”
after closing the door, the high and low temperature alarms are disabled.
7.2
CONFIGURABLE INPUT - GENERIC ALARM (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.
7.3
CONFIGURABLE INPUT - SERIOUS ALARM MODE (BAL)
When the digital input is activated, the unit will wait for “
did
” delay before signalling the
“
BAL
” alarm message. The relay outputs are switched OFF. The alarm will stop as soon
as the digital input is de-activated.
7.4
CONFIGURABLE INPUT - PRESSURE SWITCH (PAL)
If during the interval time set by “
did
” parameter, the pressure switch has reached the
number of activation of the “
nPS
” parameter, the “
PAL
” pressure alarm message will be
displayed. The compressor and the regulation are stopped. When the digital input is ON
the compressor is always OFF.
7.5
CONFIGURABLE INPUT - START DEFROST (DFR)
It executes a defrost if there are the right conditions. After the defrost is finished, the
normal regulation will restart only if the digital input is disabled otherwise the instrument will
wait until the “Mdf” safety time is expired.
7.6
CONFIGURABLE INPUT - ENERGY SAVING (ES)
The Energy Saving function allows to change the set point value as the result of the SET+
HES (parmeter) sum. This function is enabled until the digital input is activated.
7.7
CONFIGURABLE INPUT - REMOTE ON/OFF (ONF)
This function allows to switch ON and OFF the instrument.
7.8
DIGITAL INPUTS POLARITY
The digital inputs polarity depends on “
I1P
” and “
I2P
” parameters.
CL
: the digital input is activated by closing the contact.
OP
: the digital input is activated by opening the contact

INSTALLATION AND MOUNTING
Instruments
XW563L
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.

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.
9.1
PROBE CONNECTIONS
The probes 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. Place the defrost termination probe
among the evaporator fins in the coldest place, where most ice is formed, far from heaters
or from the warmest place during defrost, to prevent premature defrost termination.
10.
RS485 SERIAL LINE
The RS485 connector allows to connect the unit to a network line
ModBUS-RTU
compatible as the Dixell monitoring system XJ500 (Version 3.0).
