The quick stop condition is enabled during up and down movement during normal operation
or when the static brake tests are performed on the machine. When the beam is moving
down and the dynamic brakes tests are active the quick stop condition is disabled for
determining the stopping performance of the mechanical brakes during down movement.
The outputs used on the PCSS for the mechanical brakes are shown in
and
for the FIO04 module. The operation of the mechanical brakes occurs during
emergency braking and stopping of the machine in conjunction with the quick stop output.
