Kriwan motor protection device INT69 diagnose 22A414S82

The INT69-2 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 INT69-2 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 with compressors that are certified according to IEC/EN 60335.

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.
