Once the SET button is pressed during

a product

operation,

the auto-scrolling is de-activated so that the display does NOT change.

Another SET press will turn the current on display to the next phase one.

(e.g. If you press the SET button with L1 current displayed, the display will show L2 current.)

To re-activate the auto-scrolling, press the ESC button.In manually-scrolling display,

you can access each setting in a circular manner as pressing UP or DN.

Pressing the Fault button in the sub-function menu displays the phase and cause of the trip

for the most recent trip, and each time the DN button is pressed, R, S, T current,

ground fault current (

3EZ / FEZ / 3EBZ / FEBZ)

are sequentially displayed.

Press DN button to inquire about the previous trip. The bar graph is used to sequentially

classify the trip history.

Last recent trip: Only 100% LED is lit. Last Previous Trip: 95% and 100% LEDs are lit.

The last trip: 90%, 95% and 100% LEDs are lt. To return to the fault history inquiry menu,

press the ESC button, then press ESC once more to return to the current display.
