Why does my Cedes Safe4 show an external error?
- AAustin GutierrezAug 2, 2025
An external interface error with your Cedes Work Light can occur due to several installation-related issues. This includes a short circuit of both OSSDs, OSSD to Usp, or OSSD to GND. It may also be due to an open test input, insufficient power supply, incorrect configuration in cascading systems, or inadequate adjustment of the emitter and receiver. Correcting the installation should resolve these issues.
