Emergency

Example of speed monitoring of a drive using the engine-side
incremental encoder. An emergency stop is triggered if the speed is
exceeded when the safety door is open.
Downtime and speed monitoring
The PSR-SSM downtime monitor monitors the
downtime of a gearwheel or a gear rack. It is
controlled by two standard initiators and
additionally monitors cable or wire break.
The PSR-RSM4 speed monitor is used for
speed monitoring in automatic, special and set-
up modes and during downtime. The module is
controlled using two proximity switches or an
incremental encoder.
