Only use sensors with antivalent outputs on which one
•
contact opens before the other contact closes.
Ensure that the NO and/or NC switch on sensors with the
•
appropriate clock signal connections for the channel pair
are connected up è Circuit diagram.
Note
Safety-related evaluation only with the following connec­
tion blocks:
– CPX-M-AB-4-M12X2-5POL-T
– CPX-AB-8-KL-4POL.
