The motor protector INT69 B1 Diagnosis 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 B1 Diagnosis 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 small and medium semi-thermal piston compressors.

Functional description
The temperature monitoring of the motor winding is done with two evalua-tion 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 the AMS or PTC input also leads to a switch-off. If the lock-out bridge is installed, errors (with the exception of short circuit) always lead to a locked switch-off. Restarting after locking only after reset.

If the lock-out bridge is not inserted, the compressor can be restarted after it cools down or the error is rectified and a subsequent reset delay. A network restart has to be carried out after the lock-out bridge has been changed. For operation in the specified manner, the supply voltage has to be on permanently on the INT69 B1 Diagnosis.
