8.
DIGITAL INPUT
The digital input is enabled with P3P = n.
8.1
GENERIC ALARM (i1F = 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 = 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 = 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 = dor)
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 “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
START DEFROST (i1F = dEF)
It starts 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.
8.6
INVERSION OF THE KIND OF ACTION: HEATING-COOLING (i1F =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
HOLIDAY DEFROST (i1F = HDF) –ONLY FOR MODELS WITH RTC
This function enabled the holiday defrost setting.
8.9
ON OFF FUNCTION (i1F = onF)
To switch the controller on and off.
8.10
DIGITAL INPUTS POLARITY
The digital input polarity depends on the “i1P” parameter.
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 HOY KEY
connector. The X-REP output
EXCLUDES
the serial connection.
To connect the X-REP to the
instrument the following connectors
must be used CAB-51F(1m), CAB-
52F(2m), CAB-55F(5m),
11.
INSTALLATION AND MOUNTING
The controller XW60LS, 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.
