Electro-mechanically controlled display devices, such as reels or wheels, shall have a sufficiently closed loop of control so as to enable the software to detect a malfunction, or an attempt to interfere with the correct operation of that device. If a reel or wheel is not in the position it is supposed to be in, an error condition must be generated and reported to the on-line system;.
