4.2.11 DIGITAL INPUT (ENABLED WITH P3P = N)
The free voltage digital input is programmable in different configurations by the “i1F”
parameter.
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.
Digital inputs polarity
The digital input polarity depends on the
i1P
parameter.
i1P=CL
: the input is activated by closing the contact.
i1P=OP
: the input is activated by opening the contact
4.2.12 GENERIC ALARM (i1F = EAL)
As soon as the alarm input is activated (for example enclosure temperature higher than
ALU value) 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 alarm input is de-
activated.
4.3.13 SERIOUS ALARM MODE (i1F = bAL)
When the alarm input is activated (for example enclosure temperature higher than ALU
value), 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 alarm input is de-activated.
