guarantee safety. If you wish to achieve specific SIL/PL rank-
ing, consider introducing a power cut-off device that is controlled by an exter-
nal safety relay and cuts off the power to all QS-SB2. Example application of the
power cut-off contactor can be found in section 7.3.2 and 7.3.3.

ADDING ADDITIONAL DEVICES TO THE MOTION LOCK CIRCUIT
If there is necessity to stop other devices, apart from the QS-617/625 , ML (Motion Lock)
and additional customer devices can be controlled by safety relay outputs. In the ex-
ample application, the E-STOP button is connected to the external safety relay. When
the E-STOP is triggered, the safety relay will activate the Motion Lock function, which
will stop motion of the platform and additional devices.
