Frequently Answers and Questions
What are the temperature monitoring processes for the motor winding?
The motor winding temperature is monitored using two processes: static and dynamic. Static monitoring switches off the compressor immediately if the nominal response temperature of the built-in AMS or PTC sensors is reached. Dynamic monitoring switches off the compressor if the temperature increases unusually quickly, even if it is below the nominal response temperature, to prevent excess temperatures.
What happens if a short circuit occurs at an AMS or PTC input?
A short circuit at an AMS or PTC input will lead to a switch-off. A short cycling leads to a reset delay.
What does connecting an INT250 allow for?
Connecting an INT250 allows the differential pressure of the oil pump to be monitored. After every power reset, the compressor is only released once the INT250 is screwed in properly. After the compressor starts up, the differential pressure monitoring is active after the starting transition time of 5 seconds has elapsed.
