10. DIGITAL INPUT
One digital input is present configurable by user by means of the i1F parameter according to the following descriptions.
10.1 DOOR SWITCH (I1F = dor)
It signals the door status and the corresponding relay output status through the "odc" parameter: no = normal (any change); Fan = Fan OFF; oFF
= all the loads are switched 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 status of loads depends on the "rrd" parameter:
with rrd=no outputs are not affected by the doA alarm;
with rrd=yES = outputs restart with the doA alarm;
The alarm stops as soon as the external digital input is disabled again. During this time and then for the delay "dot" and "doH" after closing the
door, the temperature and humidity alarms are disabled.
10.2 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.
10.3 SERIOUS ALARM MODE (I1F = 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.
10.4 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 "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.
If the nPS activation in the did time is reached, switch off and on the instrument to restart normal regulation.
