5.3.- LED INDICATORS
The unit has the following LEDs:

LED ON
Green LED, indicates that the unit is voltage-fed.
The LED flashes when problems have been detected in the sensor.

LEAKAGE LED
Red LED indicates that the protection element has been tripped as a result of a residual
current intensity value that is higher than the current threshold required to trip the protection
element.

LED Bar
LED Bar indicates the leakage current level of the installation. The current levels are displayed
as a %, in accordance with the selected trip scale:
Table 3: LED Bar�
Leakage current level (%) Color LED bar
20% - 40% - 60% Green
80% Yellow
100% Red
5.4.- INPUTS
The unit has two inputs:

External current sensor input (terminals 1 and 2 in
Figure 1
). With this input the unit checks
every 5 seconds whether the connection with the external sensor is correct by means of an
inductive test.

External test input with button (terminals 7 and 8 in
Figure 1
).
Input activated by level. When voltage is applied, this forces the tripping of the unit; when it is
no longer applied the unit returns to the previous state.
The keyboard reset function will be disabled when this input is active.
