Vector Lab Products Refrigerators and Freezers 

 

9

Controllers are preprogrammed to alarm at the following temperature:
REF: High alarm: 9 C (48 .2 F), Low: 2 C (35 .6 F)
FZR: High alarm: –15 C (5 F), Low: –35 C (–32 F)
All alarm points operate off of a set SP +/- (A1/LOW, A4/HIGH) strategy .
Alarms will automatically clear when the temperature rises above/below the alarm value plus the A11 parameter 
value (Alarm offset) of 3 . In the case of a refrigerator, which low alarms at 2 C, the alarm will clear once the 
temperature rises to +2 C . Adversely, a refrigerator that enters into a high alarm at 9 C, will have the alarm clear 
once the temperature reaches 6 C .
AL on the controller screen reports a Low Temperature Alarm .
AH on the controller screen reports a High Temperature Alarm .

Defrosting

Vector Lab Products refrigerators and freezers do not require manual defrost as they utilize a hot gas defrost cycle 
to keep the evaporator coil frost free . The defrost cycle is typically always terminated when the evaporator probe 
(Pb2) reads 8 C .
If the defrost probe (Pb2) experiences a failure, or is out of spec, the MAX time the unit will stay in a defrost cycle 
is 15 minutes . If this occurs a dFd alarm will appear .
Upon termination of the defrost cycle, the compressor, condenser fan, and evaporator fan will remain off for 
60 seconds to allow for the melted frost to drip away from the evaporator coil .
Refrigerators enable an automatic defrost cycle every 10 hours
Freezers enable an automatic defrost every 6 hours .
Seeing as the cooling and defrost system are external to the cabinet, the stored product and cabinet temperature 
should experience a minimal rise during the defrost cycle .

Door Switch

Each refrigerator and freezer door is equipped with a normally opened mechanical switch that recognizes when 
the door is opened or closed . When the controller senses an interruption in the continuity of the door switch circuit, 
the evaporator fan(s) and compressor will power down . If the door remains open for longer than 2 minutes the 
controller will alternate between the temperature and an audible and visual (id) alarm will appear . Once the circuit 
is closed the alarm will clear . If an (id) alarm appears with all doors closed troubleshoot the switch circuit .
