Instruction Manual
4.4.- KEYBOARD FUNCTIONS
The device has 7 keys, Figure 8.
1.- Keys accessible with sealed cover and tool
RESET, Starts the device after a trip.
TEST, Carries out a trip to check the proper operation of the relay.
PROG/PAG, Access to prealarm programming.
2.- Access to prealarm programming
Keys with dual function. With a long press, the device is entered to set the values. With a short press,
the option within a series of values defined in the device is selected.
SENSITIVITY (Id), It allows to choose between the values of 100, 300, 500 mA , 1 and 3 A
DELAY (td), It allows to choose between the values of 100, 200, 300, 400, 500, 750 ms and
1 s.
3.- Keys accessible with sealed cover and tool
Flush buttons.
SAFETY (Std/+), This allows the output contacts polarity to be set for both the main relay
and the prealarm.
● 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 device and is deactivated with
the fault, the status is NC.
RESET PREALARM (AUTO),This allows the automatic re-establishment of the prealarm signal
to be enabled.
● In Automatic Mode (REC), if the detected leakage current is below the preset prealarm thresh-
old, the relay becomes de-activated.
● In manual mode, the device has to be RESET from the alarm screen in order to re-establish
the prealarm system.
4.5.- DISPLAY
The device has a backlit display with green or red light, depending on the state of the device.
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 leak-
age current.
