system, read the whole section to have a good understanding of how to apply
and what functionality to expect. Apply at your own discretion.

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 6.3.2 and 6.3.3.

ADDING ADDITIONAL DEVICES TO THE MOTION LOCK CIRCUIT

If there is necessity to stop other devices, apart from the QS-S25, ML (Motion Lock) and
additional customer devices can be controlled by safety relay outputs. In the example
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.
