7. 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 - PANIC ALARM (i2F = PAn)
As soon as the digital input is activated the unit displays the "PAn" alarm message, the alarm buzzer, relay and panic LED are activated. The other
outputs status don't change. The alarm stops just after the digital input is de-activated.
7.4 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.
7.5 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.
7.6 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.
7.7 CONFIGURABLE INPUT - RELAY AUX ACTUATION (AUS)
This function allows to turn ON and OFF the auxiliary relay by using the digital input as external switch.
7.8 CONFIGURABLE INPUT - ENERGY SAVING (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.
7.9 CONFIGURABLE INPUT - REMOTE ON/OFF (ONF)
This function allows to switch ON and OFF the instrument.
7.10 CONFIGURABLE INPUT - HOLIDAY FUNCTION (HDF)
In Holiday function Energy saving and defrost cycles follow holiday times. (Sd1...Sd8)
7.11 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
