KRIWAN MOTOR PROTECTOR INT69 TM2 DIAGNOSE
Application:
The motor protector INT69 TM2 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. INT69 TM2 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 TM2 Diagnose.
