Special status screens
The special status screens are displayed depending on events that occur during the product life. The screens depend on the event type but always trigger the product status LED to red and the insulation alarm relay is active. If the preventive insulation alarm relay is configured in mirror mode, it is also triggered and no longer mirrors the insulation alarm relay.
Over-limit capacitance detection
The over-limit capacitance detection state is triggered when the capacitance of the monitored system becomes too high. For details on the device specification, refer to Specifications. In case of detected over-limit capacitance, the device can not monitor the system.
Power Circuit or Control Ciruit
Photovoltaic Circuit (IM400-1700)
The overvoltage state is triggered when the voltage of the monitored system becomes too high. For details on the device specification, refer to Specifications. In case of overvoltage, the device can not monitor the system and the device automatically disconnects the power system. Disconnect the auxiliary power supply of device and reconnect.
The inoperative product state is triggered when the device is inoperative.
