PROBE INPUTS
Ot
Thermostat probe calibration:
(-12.0
÷
12.0°C/ -21
÷
21°F) allows to adjust possible offset of the thermostat probe.
OE
Evaporator probe calibration:
(-12.0
÷
12.0°C/ -21
÷
21°F) allows to adjust possible offsets of the evaporator probe.
O3
Humidity probe calibration:
(-10
÷
10 RH) allows to adjust possible offsets of the humidity probe.
P2P
Evaporator probe presence: n
= not present: the defrost stops only by time;
y=
present: the defrost stops by temperature and time.
P3P
Humidity probe presence: n
= not present;
y=
present.
LCI
Readout with 4 mA
: (-999 ÷ 999). Adjustment of read out corresponding to 4mA signal.
UCI
Readout with 20 mA
: (-999 ÷ 999). Adjustment of read out corresponding to 20mA signal.
DIGITAL INPUTS
i1P
Configurable digital input polarity: CL
: the digital input is activated by closing the contact;
OP
: the digital input is activated by
opening the contact;
i1P
Door switch digital input polarity: CL
: the digital input is activated by closing the contact;
OP
: the digital input is activated by
opening the contact
i1F
Digital input operating mode:
configure the digital input function:
EAL
= generic alarm;
bAL
= serious alarm mode;
PAL
= Pressure
switch;
Ht
= heating relay safety;
dor
= door switch
odc
Outputs status when open door:
on
= normal;
Fan
= Fan OFF;
oFF
= all the loads off
rrd
Outputs restarting after doA alarm: no =
outputs not affected by the doA alarm;
yES =
outputs restart with the doA alarm;
did
Time interval/delay for digital input alarm:
(0
÷
255 min.) Time interval to calculate the number of the pressure switch activation when
I1F=PAL. If I1F=EAL or bAL (external alarms), “did” parameter defines the time delay between the detection and the successive signalling
of alarms.

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.
