Note: Past trip records (trip records retained or trips that occurred in the past) can be called up.
⇒ See section 8.1 "Status monitor mode" for the call-up procedure.
(*) Strictly speaking, this code is not an error code; this code is displayed to show the absence of error
when the past trip monitor mode is selected.
8.2.2 Display of trip information at the occurrence of a trip
At the occurrence of a trip, the same information as that displayed in the mode described in 8.1.1, "Status monitor
under normal conditions," can be displayed, as shown in the table below, if the inverter is not turned off or reset.
To display trip information after turning off or resetting the inverter, follow the steps described in 8.1.2, "Display of
