The speed­monitoring device must be connected in such a manner that the main drive is disabled
automatically at "> Zero" speed at the output shaft of the auxiliary drive. For safety reasons, the disabling
function must be checked at regular intervals, i.e. at least quarterly. To check the disabling function, the
auxiliary drive is switched on. If the speed­monitoring device connects ­ which can be verified, for instance,
by means of a warning light ­ the speed­monitoring device is ready for operation.
This speed­monitoring device is an absolute must for safety reasons since in case of
a defect in the overrunning system the auxiliary drive can be destroyed with explosive
effect due to overspeeds.
