This device belongs to the Vigilohm range designed to monitor ungrounded/IT electrical networks at feeder level, in accordance to installation and products standards This insulation fault location is only possible when it is associated to IM400 series, XM300 or XM200. This device is dedicated to monitoring 12 feeders, AC, DC and ACDC, up to the toroid limit, 1000V. Configuration is set from the front of the device, through the HMI screen. Settings are related to alarm thresholds. It displays which feeder has an insulation fault. Auto-test starts automatically every 5 hours, and on demand. In case the insulation resistance drops below the set threshold, an alarm is triggered thru the IFL output relay and HMI. Once no fault is monitored, the alarm is cleared, the alarm relay is back to normal. The device can be supplied by a 110VAC to 440VAC source or a 110VDC to 440VDC, all with a tolérence of plus or minus 15%.
