The 100N MASTER for the Pego VISION SC600 refers to the control circuit board that manages system operations. If an EEPROM memory error (E0) is detected in the 100N MASTER, the system disables all outputs except shut-down alarm outputs. The recommended actions are to switch the appliance off and back on, and if the problem persists, replace the control circuit board.
