The INT69 B1 Diagnose motor protection is a further development of the existing KRIWAN trigger device. Using additional protective functions that respond flexibly, increased availability and a longer service life of the refrigeration system is achieved.
The INT69 B1 Diagnose stores operating and fault data in non-volatile memory. This data can be exported to a PC and analysed for diagnostic purposes. The full scope of diagnostic options is achieved by using the KRIWAN-specific AMS sensor.
This trigger device is primarily used in small and medium-sized semi-hermetic reciprocating piston compressors.
Features
Temperature monitoring in the motor winding is done using two different methods:
Static: When the rated trigger temperature of the integrated AMS or PTC sensors is reached, an immediate shut-off occurs.
Dynamic: If the temperature increases unusually fast, the motor is immediately switched off, ...
Temperature monitoring in the motor winding is done using two different methods:
Static: When the rated trigger temperature of the integrated AMS or PTC sensors is reached, an immediate shut-off occurs.
Dynamic: If the temperature increases unusually fast, the motor is immediately switched off, even if the temperature is still far below the trigger temperature. This prevents high excess temperatures.
