(2) When required by R 408.12461 of this part, the brake monitor shall meet the following requirements: (a) Be so constructed as to automatically prevent the activation of a successive stroke if the stopping time or braking distance deteriorates to a point where the safety distance being utilized does not meet the requirements prescribed in R 408.12463(1) and (7). The brake monitor used with the type B gate or movable barrier device shall be installed in a manner to detect slide top-stop overrun beyond the normal limit reasonably established by the employer. (b) Be installed on a press in such a way that it indicates when the performance of the braking system has deteriorated to the extent described in subdivision (a) of this subrule. (c) Be constructed and installed in a manner to monitor brake system performance on each stroke or each time the brakes are applied.
