CONNECTION DIAGRAM
The riese SAFE SM is a safe standstill monitor. It is designed to monitor
safe speeds. Digitally switches e.g. inductive sensors or ESPD’s are
supported. SAFE SM is a two channel device. Therefore, two digitally
switches are necessary. Four safe speeds are monitored: 0.2 Hz, 0.5 Hz,
1.0 Hz and 2.0 Hz, the shifting is done via configuration wirings.
