The actuator can approach the switch from the front or the sides. Ensure the marked sensing faces match up directly. LED Status Indicators
Industrial safety standards (ISO 13849-1) require periodic testing of interlock devices.
When the GS-11PC encounters an issue, the main multi-color LED provides immediate diagnostic feedback. LED Behavior Potential Cause Action Plan No power supply Check 24 VDC and 0 VDC wiring connection. Flashing Red (1 time) OSSD output fault Check for short circuits between OSSD lines or to 24V/0V. Flashing Red (2 times) OSSD input fault Verify upstream cascaded switches are powered and aligned. Flashing Red (3 times) Actuator error Ensure the correct paired RFID actuator is being used. Flashing Orange Poor alignment Readjust the mechanical gap between switch and actuator. 6. Maintenance and Safety Inspections

Turn off the power supply. Disconnect the M12 cordset and verify with a multimeter that OSSD 1 and OSSD 2 are not shorted to +24VDC, 0VDC, or each other. Restart the power supply. Issue 2: LED Stays Red Even When Guard is Closed Cause: Misalignment or incorrect actuator code tracking.

When using the GS-11PC as a standalone unit (not cascaded), the OSSD inputs must be tied to +24 VDC to enable the outputs. Connect to +24 VDC. Connect Pin 7 (Blue) to 0 VDC. Connect Pin 4 (Yellow) and Pin 8 (Red) to +24 VDC. Are you dealing with an , wiring ,
The manual points to electromagnetic noise. Use a ferrite core (clamp filter) on the cable near the sensor head. Also, verify the shield (Pin 5) is grounded at only one end (controller side) to avoid ground loops.
