d. INT69HBY diagnose motor protector and PTC temperature sensor
In order to protect compressors, each RC2-AVI series compressor has been installed three PTC temperature sensors
(thermistors) inside motor coil and another one at the discharge port of the compressor. These sensors are connected
to an INT69HBY diagnose protection module to monitor the motor coil temperature and the discharge temperature as
well. If the temperature in one of the positions monitored exceeds the nominal response temperature of the respective
PTC thermistors, the sensor resistance increases and the INT69HBY diagnose protection module output relay trips.

Other major functional descriptions are as follow:
1. 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.
2. A short circuit at an AMS or PTC input also leads to a switch-off. A short cycling leads to a reset delay.
3. After cooldown or elimination of the error and a subsequent reset delay, the compressor can be restarted;
restarting after locking only after reset.
4. For operation in the specified manner, the supply voltage has to be on permanently on the INT69 HBY Diagnose.
5. A dual LED (red, orange/ green) provides additional information about the motor protector and compressor status.
