Possible Causes
Corrupted firmware in Calpeda controller, Power supply instability to controller PCB, Overheating of Calpeda control electronics, Age-related failure of controller components
How to Fix / Troubleshooting
Safety first: Disconnect power before opening the controller enclosure.
- Check controller environment: Ensure the Calpeda control box is installed in a dry, ventilated location away from direct sun and chemical fumes. Overheating and corrosion can damage electronics.
- Inspect power supply: Verify that the low-voltage power supply feeding the controller PCB is within the specified range. Replace any failing auxiliary power supply modules.
- Firmware reset/update: If supported, perform a factory reset of the controller parameters. Consult Calpeda documentation for firmware update procedures and apply the latest stable firmware.
- Check for moisture and corrosion: Look for signs of water ingress, condensation, or corroded connectors on the PCB. Dry the enclosure and replace damaged gaskets or cable glands.
- Replace controller if necessary: If E13 persists after environmental and power checks, the controller PCB is likely defective and should be replaced with a Calpeda original part.
