Functionreset:
rotation direction signaling: reset in preferred direction (left-hand rotation)
slip monitoring: reset slip error
hold:
slip monitoring: if the input is bridged, the Hold function becomes active. Lead fault is only indicated by relay 2 and combined fault indication. The condition of the relay is hold during fault.
