Alarms
A0 Configuration of the temperature alarms 0=Relative to SP 1=Absolute
A1 Alarm for maximum in sensor 1 (it must be higher than the SP)
A2 Alarm for minimum in sensor 1 (it must be lower than the SP)
A3
Delay of temperature alarms in the start-up
A4 Delay of temperature alarms from the end of a defrost
A5 Delay of temperature alarms from when the A1 or A2 value is reached
Delay of external alarm/severe external alarm on receiving digital input signal
A6
(I10 or I20=2 or 3)
External alarm deactivation delay / Severe external alarm on
A7
disappearance of signal at digital input (I10 or I20=2 or 3)
A8 Show warning if the defrost ends for maximum time 0=No 1=Yes
Polarity relay alarm 0= Relay ON in alarm (OFF without alarm);
A9
1= Relay OFF in alarm (ON without alarm)
A10
Differential of temperature alarms (A1 and A2)
A12 Delay of open door alarm (if I10 or I20=1)
A20 Minimum superheating value for LSH alarm
A21 LSH alarm activation delay
A22 LSH alarm hysteresis
A23 Maximum superheating value for HSH warning
A24 Delayed activation of the HSH warning
A25 HSH alarm deactivation hysteresis
A26 Maximum evaporating pressure (MOP)
MOP alarm activation delay (Delay time for activating alarm after threshold
A27
has been exceeded)
MOP alarm deactivation hysteresis (When the pressure drops below the
A28
MOP-hysteresis level the alarm is deactivated)
A29 Minimum evaporating pressure (LOP)
LOP alarm activation delay (Delay time for activating alarm after threshold has
A30
been exceeded)
LOP alarm deactivation hysteresis (When the pressure exceeds the LOP+
A31
hysteresis level the alarm is deactivated)
