(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.
