How to troubleshoot a GSE Process Controller that is not operating?
- LLuis MclaughlinAug 2, 2025
If the GSE Process Controller isn't operating, first ensure it's connected to the AC power supply. Check that the red, white, and black wires from the Alpha Keypad to the main controller board are correctly connected. Verify the COM4 Port protocol matches the alpha keypad protocol. Also, check the display for any error messages. Finally, consider updating the firmware to the latest version.
