Operating instruction |
The microprocessor-controlled milk cooling temperature regulator MRF-M is used to control agitator motors and refrigeration compressors on milk cooling equipment.
|
- Easy operation via three work levels
- 2 freely selectable target temperatures
- Various intermediate stirring functions
- Intermediate stirring times freely programmable
- Buttons for “Target temperature switchover” and “Intermediate stirring”
- Option of switching to “Permanent stirring”
- Automatic subsequent stirring
- Adjustable cooling start delay
- Freely selectable target temperatures and hysteresis
- LED display of agitator and compressor status
- Target temperature limits freely adjustable
- Lockable buttons to prevent changes to target tempe-rature
- Alarm in the event of sensor short-circuit/sensor fault (adjustable relay switching state in event of fault)
- Adjustable minimum action time and minimum pause time for output relays
- Automatic parameter storage without data loss when a power-cut occurs
