Mounting position

Confirm that the proximity switch indicator LED turns to green when the lever is pushed towards the proximity switch side. (Figure 1)
Confirm that the proximity switch indicator LED turns to green when the lever is pushed towards the opposite side from the proximity switch. (Figure 2)
Then, rotate the lever by 90° to confirm that the indicator LED of the proximity switch (red, green) does not turn on.
Fix the cylinder with screws included as accessories after confirming that there is no interference between the lever and the proximity switch.
