The actuator is too far from the sensor or is the wrong model. Ensure you are using the GS-A22 or GS-A30 actuator.
The sensor and actuator must be mounted so that the sensing faces meet when the guard is closed. Ensure the gap between the sensor and actuator does not exceed the specified sensing range (usually 5-10mm for stable operation). 3. Alignment Indicators Guard is closed and safety outputs are ON. Red: Guard is open or misaligned; safety outputs are OFF. keyence gs-11pc manual
Check for physical damage to the sensor housing or the M12 cable. The actuator is too far from the sensor
Open the guard to ensure the machine stops immediately. Ensure the gap between the sensor and actuator
The sensor is vibrating or the door is sagging, causing the actuator to drift in and out of the sensing range. Tighten the mounting brackets. Maintenance and Safety Checks
