This device belongs to the Vigilohm range designed for monitoring ungrounded power supplies (IT systems) in accordance with installation and product standards. This insulation fault location is only possible when connected to IM400 series, XM300 or XM200. This device is designed to monitor 12 AC, DC and ACDC feeders up to toroidal voltage of 1000 V. The configuration is set from the front of the device through the HMI screen. The settings refer to the alarm thresholds. It indicates which feeder has an insulation fault. Autotest starts automatically every 5 hours and when required. If the insulation resistance drops below the set threshold, an alarm is triggered via the IFL output relay and the HMI. Once no more fault is detected, the alarm is cleared and the alarm relay returns to normal state. The unit can be powered from a 110VAC to 440VAC source or a 110VDC to 440VDC source, all with a tolerance of plus or minus 15%.
