Accessible with cover raised. Keys with dual function. With a long press, the equipment is entered to set the values.
With a short press, the option within a series of values defined in the equipment is selected.
SENSIVITY button, I
∆
N
This allows values between 30, 100, 300, 500 mA , 1 and 3 A to be selected
This scale can be extended using the SETUP program to add 5, 10 and 30 A to the above values.
DELAY button, t
d
This allows 20, 100, 200, 300, 400, 500, 750 500 ms and 1 second to be selected.
This scale can be extended using the SETUP program to add 3, 5 and 10 seconds to the above values.
This person also allows browsing within the SET UP MENU.

NORMAL OR POSITIVE SAFETY button
This allows the output contacts' polarity to be set for both the main relay and the pre-alarm.
With normal safety (Std) the relay is activated with a fault, the status is NO.
With positive safety (+) the relay is activated on supplying the equipment and is deactivated with the fault, the
status is NC.
ALARM RESET button
This allows the automatic re-establishment of the pre-alarm signal to be enabled.
In Automatic Mode (REC), if the detected leakage current is below the preset pre-alarm threshold, the relay
becomes de-activated.
In manual mode, the equipment has to be RESET from the alarm screen in order to re-establish the pre-alarm
system.
The equipment displays and sets or these directly set parameters by direct setting or by programming the SETUP
program from the display.
Backlit display, LCD
The background to the screen in normal mode is green. The parameters required for earth leakage protection,
sensitivity and delay in its associated units are displayed. It also displays the current leakage current.
If the equipment trips through any event, the screen's background changes to red and the reason for the trip is
displayed.
