Acknowledge button with request
This application example shows the circuitry of a button with a light signal. Actuation of the button
can only be evaluated while clock signal connection T0 of a channel pair is connected to a 24 V power
source. The LED on the button lights at the same time to indicate the possible evaluation of this
actuation.

This circuit only functions by switching between function modes 1 and 2 in the safety program.
NOTICE
The safety-related evaluation in this example is only possible on the following manifold blocks:
• CPX-M-AB-4-M12X2-5POL-T
• CPX-AB-8-KL-4POL.
When using manifold block CPX-AB-8-KL-4POL ("CAGE CLAMP“ connection technology), another
sensor/switch can be connected to the channel pair via terminals 24 V and E1.
