Self-supervision alarmFigure: ARCON 2.0 has detected an internal faultThe system’s self-supervision function continuously monitors the operation of the arc protec-tion system. The self-supervision function supervises all the components and cables of thesystem. When self-supervision detects an internal fault, it activates the SF alarm relay in themaster unit and lights the ERROR indicator LED.Self-supervision generates a fault code for the detected fault, which is stored in the fault me-mory of the master unit. The fault memory may contain up to three faults (latest faults).Fault codes can be red only in ERROR CODE mode.Figure: Reading and resetting the fault memoryTo reset the arc fault memory, do the following:• Press the S button to activate the ERROR CODE mode. The fault code starts blinking.• Press the E button to erase the latest fault code from the memory. The next fault code,if any, appears on the screen.• Once you have acknowledged each fault code separately, the display becomes dark inthe ERROR CODE mode.NOTE! If the fault that caused the fault code disappears by itself, the fault code in the fault memory isalso erased automatically two hours after the disappearance of the fault.23ARC-EM/2.0ERROR CODESEI/O UNIT ERROR CODECLEARINGOF MEMORYI/O UNIT ERROR CODE I/O UNIT ERROR CODE
