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.
Temperature alarm differential: (0.1 to 25.0°C; 1 to 45°F) alarm differential.
Temperature alarm delay: (0 to 255 min) delay time between the detection of an alarm condition
and the relative alarm signaling.
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.
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.
Probe selection for 2nd temperature alarm: (nP; P1; P2; P3; P4) nP=no probe; Px=probe “x”.
Note: P4=Probe on Hot Key plug.
Pre-alarm threshold for 2nd temperature alarm (absolute value): (-55.0 to 110.0°C; -67 to
230°F)
Second high temperature pre-alarm differential: (0.1 to 25.0°C; 1 to 45°F)
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.
Second low temperature alarm: (-55.0 to 110.0°C; -67 to 230°F)
Second high temperature alarm: (-55.0 to 110.0°C; -67 to 230°F)
Second temperature alarm differential: (0.1 to 25.0°C; 1 to 45°F)
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.
Second temperature alarm delay at start-up: (0.0 to 24h00min, res. 10 min)
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.
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.
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.
7.1.8 DIGITAL OUTPUTS - oUt
Relay output oAx configuration:
- nu= not used
- CP1= compressor management
- dEF= defrost
- FAn= evaporator fan
- ALr= alarm
- LiG= light output
- AUS= auxiliary output
- db= dead band output
- onF= onoff output
- HES= energy saving output
- CP2= second compressor management
Alarm relay polarity: (CL; oP) oP = alarm activated by closing the contact; CL = alarm
activated by opening the contact.
7.1.9 DIGITAL INPUTS – inP
Base times for digital inputs: (SEC; Min) SEC = seconds; Min = minutes. Delay in activating the
function linked to the digital inputs.
Digital input 1 polarity: (CL; oP) oP = activated by closing the contact; CL = activated by
opening the contact.
