When needed, set the Modbus address (SETUP→MB Addr). • If needed, enable the automatic alarm acknowledgement (SETUP→AutoRst). A more detailed description of the configuration is provided in the Manual section “SETUP menu”. Superintend IMD © Copyright Muuntosähkö Oy - Trafox http://www.trafox.fi... -

PE conductor. These generate a low current that travels through the insulation resistance and capacitance to be measured. The insulation resistance and capacitance are calculated by FFT analysing the current and then measuring the amplitude and phase. © Copyright Muuntosähkö Oy – Trafox Superintend IMD http://www.trafox.fi... -

All fixed faults can also be acknowledged on one go by means of the Alarm reset function in the Monitor menu. If the automatic alarm acknowledgement has been enabled (SETUP→AutoRst), the faults are acknowledged automatically as soon as they are fixed. © Copyright Muuntosähkö Oy – Trafox Superintend IMD http://www.trafox.fi... - Page 13 The insulation fault alarm is active. The smallest insulation resistance measured during the fault is 850 kΩ and the alarm limit is 900 kΩ. The insulation fault alarm has been deactivated but not acknowledged.
