ALU
High temperature alarm:
when this temperature is reached, the alarm is enabled after the
Ad
delay time.
•
If
ALC=Ab
→
ALL to 110.0°C or ALL to 230°F.
•
If
ALC=rE
→
0.0 to 50.0°C or 0 to 90°F.
AFH
Temperature alarm differential:
(0.1 to 25.0°C; 1 to 45°F) alarm differential.
ALd
Temperature alarm delay:
(0 to 255 min) delay time between the detection of an alarm condition
and the relative alarm signaling.
dot
Temperature alarm delay with open door:
(0.0 to 24min00sec) delay before activating door
open alarm. NOTE: digital input delays (par.
dxd
) are not considered when
ixF=dor
.
dAo
Temperature alarm delay at start-up:
(0.0 to 24h00min, res. 10 min) delay time between the
detection of a temperature alarm condition and the relative alarm signaling, after starting up the
instrument.
AP2
Probe selection for 2nd temperature alarm: (nP; P1; P2; P3; P4) nP=
no probe;
Px=
probe “x”.
Note: P4=
Probe on Hot Key plug.
AU1
Pre-alarm threshold for 2nd temperature alarm (absolute value):
(-55.0 to 110.0°C; -67 to
230°F)
AH1
Second high temperature pre-alarm differential:
(0.1 to 25.0°C; 1 to 45°F)
Ad1
Second high temperature pre-alarm delay:
(0 to 255 min; 255 = not used) delay time between
the detection of a condenser pre-alarm condition and the relative alarm signaling.
AL2
Second low temperature alarm:
(-55.0 to 110.0°C; -67 to 230°F)
AU2
Second high temperature alarm:
(-55.0 to 110.0°C; -67 to 230°F)
AH2
Second temperature alarm differential:
(0.1 to 25.0°C; 1 to 45°F)
Ad2
Second temperature alarm delay: (
0 to 255 min; 255 = not used) delay time between the
detection of a condenser alarm condition and the relative alarm signaling.
dA2
Second temperature alarm delay at start-up:
(0.0 to 24h00min, res. 10 min)
bLL
Compressor OFF due to 2nd low temperature alarm: (n; Y) n =
no, the compressor continues
to work;
Y =
yes, the compressor is switched off while the alarm is ON; in any case, the regulation
restarts after AC time at minimum.
AC2
Compressor OFF due to 2nd high temperature alarm: (n; Y) n =
no, the compressor continues
to work;
Y =
yes, the compressor is switched off while the alarm is ON; in any case, the regulation
restarts after AC time at minimum.
tbA
Alarm relay deactivation: (n; Y) n =
no, it is not possible to deactivate neither the buzzer nor any
digital output set as an alarm;
Y =
yes, it is possible to deactivate both the buzzer and the digital
output set as an alarm.
