Low pressure alarm delay from a digital/analogue input
AL 2
Defines low pressure alarm operation with pump-down enabled
0 = independent from the pump down
1 = blocks the compressors until the pressure switch is disabled
2 = lets the compressors reach peak values
AL 5
Maximum number of interventions per hour of the low pressure alarm from a
digital/analogue input. If the number exceeds AL05 the alarm becomes
manual reset.
Reset is always manual if AL05 = 0
Reset is always automatic if AL05 = 60
Reset moves from automatic to manual if AL05 moves from 1 to 59
AL 6
Low temperature / pressure alarm in defrost mode
0 = not enabled
1 = enabled
AL 7
Low temperature / pressure alarm delay in defrost mode
Delay time between alarm condition occurrence and reaction by device
