Issue
How to set an LNC-100 back to factory-default settings. This will erase all block programming and device configuration.
Environment
Network 8000 LNC-100 and related controllers based on the GCM-861X0 series platform, including the GCM-86110,
GCM-86120, SIM-CCN, SIM-MTECH, SIM-TRANE, and SIM-YORK
Cause
Sometimes it is necessary to manually clear the controller EEPROM in order to reload a database.
Resolution
Follow the steps below:
- Backup the controller database.
- Clear the controller's EEPROM. This is accomplished by pushing the reset button and the EE CLR button and holding both for at least 20 seconds before releasing. The reset process is complete when the top two red LEDs on the right edge of the controller begin blinking in their normal sequence (second LED blinks twice as fast as top LED). This process will clear the user programmable memory (including all block programming), returning the controller to its original factory condition. This step is important as it insures there will be no conflict between the new revisions firmware and the older version.
The procedure above is excerpted from Technical Bulletin 99-27 , steps 1 and 2.
