you will register these particular faults every time you lose power, or every time you throw the main line switch. it indicates no voltage to the rec board.

188 and 187 are, rope gripper failed to pick faults. could be a switch in the rope gripper itself or a bad k464.1 or k464.2 relay on the adon board, if the gripper is ok you may have an early version of adon bd. they weren't that reliable.
