Description
Unicode evaluation
Each actuator is highly coded (unicode). The switch detects only taught-in actuators. Additional actuators can be taught-in. Only the last actuator taught-in is detected.
Control of guard locking via IO-Link communication
Activating guard locking: | Guard locking powered by the device’s operating voltage and controlled by bit CL (bit CL = 1). |
Releasing guard locking: | Guard locking released by spring force and deactivated by bit CL (bit CL = 0). |
