symbol AL appears on the display.
2. Confirm with Enter. The parameter response value > I2 flashes, in addi-
tion the associated overcurrent value > 30 mA appears.
3. Use the Down key to select the parameter response value I1. The para-
meter I1 flashes, in addition the associated percentage value for
prewarning 50 % of I2 appears.
4. Confirm with Enter. The current value for prewarning appears on the
flashing display.
5. Use the Up or Down key to set the appropriate prewarning value. Con-
firm with Enter. I1 flashes.
6. You can exit the menu by:
– pressing the Enter key for more than 1.5 seconds to reach the next
higher level or
– selecting the menu item ESC and confirming with Enter to reach the
