ApplicationThe KRIWAN INT69 VSY-II protection module complements theconvential temperature monitoring function of the well-known switchingdevice INT69 VS with phase sequence monitoring (Y) for screw andscroll compressors.

Functional descriptionIf the response temperature of any of the connected thermistors isexceeded, the module trips and locks out. The phase sequencemonitor on the three-phase supply is active when the supply voltage isalso present on terminal D1 (typically via contactor auxiliary contact). Ananticlockwise phase sequence also results in a trip and lockout. The D1input allows the user to suppress reverse rotation tripping due to pres-sure equalisation after shutdown on screw compressors. The lockoutcan be cancelled by interrupting mains supply for approx. 5 seconds.
