KRIWAN MOTOR PROTECTOR INT69-2 DIAGNOSE ( 22A445S80 )
Application

The motor protector INT69-2 Diagnose is a further development of the reliable KRIWAN motor protectors. Its supplementary flexible-response protective functions help to improve the availability and extend the service life of a refrigeration system.

The INT69-2 Diagnose automatically saves operational and error data in a non-volatile memory. This data can be retrieved on a PC and analysed for diagnosis. The full scope of the diagnosis is achieved by using a KRIWAN-specific AMS sensor.

This motor protector is mainly employed on compressors which are qualified acc. to IEC/EN 60335.

Functional description

The temperature monitoring of the motor winding is done with two evaluation processes:

• Static: Switch-off is immediate if the nominal response temperature of the built-in AMS or PTC sensors is reached.

• Dynamic: If the temperature increases unusually quickly, the motor is switched off immediately even if the temperature is still far below the nominal response temperature. This prevents excess temperatures from occurring.

A short circuit at an AMS or PTC input also leads to a switch-off.

After expiration of the reset delay and elimination of the error or cool-down, the compressor can be restarted. For operation in the specified manner, the supply voltage has to be on permanently on the INT69-2 Diagnose.
