Tesys GV Manual StarterResolution:
The instantaneous aux contacts change state to follow the GV2 control as it is mechanically moved to the energized or deenergized position. The fault signaling contacts change state in the event of any fault (i.e. overload or short circuit) condition only. Otherwise, they are not affected by the movement of the control from energized to deenergized state.
