1592025050 iProChill v2.5 10D00 AG v1.3 GB 18.02.2016.docx iProCHILL 170/205
With circuit low pressure pressure switch active. From DI Low pressure
switch circuit 1…4 (DI type=14…17)
If AL08=1, also with unit in stand-by or OFF remote, if circuit low pressure
pressure switch input active
In defrost if AL06=1 if compressor low pressure pressure switch input
active
The alarm is not signalled:
1. in defrost for time AL07 in correspondence with activation of the reverse
valve cycle
2. On compressor switch-on for the time AL01
3. AL02 = 0 the low pressure alarm is inhibited during compressor stopping in
pump down mode and with compressor at a standstill
4. AL02 ≠ 0 the low pressure alarm is inhibited during compressor stopping in
pump down mode and with compressor at a standstill for the time set
Automatic – it becomes manual after AL05 interventions/hour (reset procedure

10.5 OIL FLOAT/PRESSURE SWITCH ALARM
OPC1-…OPC16 (compressor n°1…16 oil pressure switch alarm)
DI configured as Oil pressure/level switch compressor 1 (DI type=69…84)
activated.
The alarm is not signalled: on compressor switch-on for the time AL12. After
time AL12 it is not signalled with unit in normal working conditions for time
AL13. If AL15 = 0 the alarm is not detected with the compressor off
Automatic – it becomes manual after AL14 interventions/hour (reset procedure
