DIGITAL INPUT
The free voltage digital inputs are programmable in different configurations by the
i1F or i2F
parameters.
16.1
DOOR SWITCH INPUT (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.
16.2
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 doesn’t change. The alarm stops just after the digital input is de
-
activated.
16.3
SERIOUS ALARM MODE (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.
16.4
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 “
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.
16.5
AUXILIARY OUTPUT CONTROL (AUS)
To activate and deactivate the auxiliary output
