The 18 Series granulator has a standstill monitor, which senses inductively when
the cutter has stopped. The standstill monitor locks the breaking key to the locking
device on the door to the cutter house, so long time as the cutter is in motion.
The locking device to the cutter house door can not be opened if the cutter is in
motion.
