Using a GVAM11 combined with a GVAD10xx, it is possible to distinguish between thermal and and magnetic faults.
If there is no fault:
- GVAM11: contact 05-06 is closed and contact 05-08 is open
- GVAD10xx: fault contact 97-98 is open
- No LED is lit
If there is a magnetic fault:
- GVAM11: contact 05-06 is open and contact 05-08 is closed
- GVAD10xx: fault contact 97-98 is closed
- The short-circuit LED is lit, and the trip LED is off
If there is a thermal fault
- GVAM11: contact 05-06 is closed and contact 05-08 is open
- GVAD10xx: fault contact 97-98 is closed
- The trip LED is lit, and the short-circuit LED is off
Test for correct operation
The instantaneous auxiliary contact test is performed by creating a state of transition of the handle actuator between the de-energised position and the energised position.
The fault contact test is performed by pressing the test button when the handle actuator is in the closed position.
