9. DIGITAL INPUTS
The first digital input (XW30LH: terminals 13-14; XW30LRH: terminals 14-15) is enabled if P3P=n.
With P3P=n and i1F=i2F the second digital input will be disabled.
The free voltage digital inputs are programmable by the i1F and i2F parameters.
9.1 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 doesn't change. The alarm stops just after the digital input is de-
activated.
9.2 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.
9.3 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.
9.4 DOOR SWITCH INPUT (i1F or i2F = 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 if 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.
