KRIWAN MOTOR PROTECTOR INT69 KF2 DIAGNOSE ( 22A650S80 / 22A622S80 )
Application
The motor protector INT69 KF2 Diagnose is a further development of the reliable KRIWAN motor protectors.
The INT69 KF2 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 in the motor winding is done according to the static evaluation process; the motor is switched off immediately if the nominal response temperature of the built-in AMS or PTC sensors is reached.
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 cooldown, the compressor can be restarted. For operation in the specified manner, the supply voltage has to be on permanently on the INT69 KF2 Diagnose.
