I cannot reproduce the entire copyrighted manual. However, you can obtain it directly from Keyence:

Safety guards are closed. Actuator is detected. OSSDs are active (ON).

Proper physical alignment prevents nuisance trips and ensures the RFID handshake functions reliably. Mounting Rules

Proper alignment between the sensor head (GS-11PC) and the actuator is critical to prevent nuisance trips and intermittent machine stoppages. Mounting Steps

Inspect structural door hinges for mechanical play or sagging that changes the alignment during operation.

The device must be installed in accordance with local, state, and national regulations.

The GS-11PC is a sensor head; it may not have a separate manual but instead be documented within a series manual (e.g., “GT Series Digital Sensor Amplifier Manual”). Make sure you also have the manual for the amplifier unit (e.g., GT2-71N) to which the GS-11PC connects.

Pro tip: teach operators one “starter routine” — zero, check with a master, run five samples. Simplicity improves adoption.
