6. ADVANCED APPLICATIONS
INFO
Examples shown in this section describes optional application of external safety
and power cut-off devices. If you wish to expand the functionality of your motion
system, read the whole section to have a good understanding of how to apply
and what functionality to expect. Apply at your own discretion.
WARNING
Motion Lock input is not a SIL/PL (safety integrity level/performance level) rated
and
DOES NOT guarantee safety. If you wish to achieve specific SIL/PL ranking,
consider introducing a power cut-off device that is controlled by an external
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.
INFO
When applying safety relay to the Motion Lock :
■
Use input cables according to your safety relay manual.
■
Use output cables according to your safety relay manual and cross section
no less than 0,75 mm

6.1. ADDING ADDITIONAL DEVICES TO THE MOTION LOCK CIRCUIT
If there is necessity to stop other devices, apart from the QS-210, ML (Motion Lock)
and additional user 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.
