If power is injected into the grid during the period defined by the Stop time
parameter, relay number 4 (NO (terminals 9- 10)) is desactivated (If Stop time is
programmed with the value 0 this function remains deactivated). In addition, an
orange alarm icon appears on the web site, as shown in Figure 7:
