The alignment level is monitored also during device normal operating mode, and is visualized by a bar graph
shown on the user interface. Once the curtain has been aligned and correctly fastened, the display signal is
useful to check the alignment and to view any change in the environmental conditions (presence of dust,
light disturbance and so on). The behaviour is resumed in the next table.

7.2 CORRECT MUTING ARM ALIGNMENT PROCEDURE
Once effected the safety light curtain alignment and the mechanical arm mounting and the relative
connection, ensure the correct alignment of the arm sensors regulating the fixing bracket.

The arm position can be modified vertically and horizontally respect to the main axis.
Avoid unsafe alignment conditions; carefully check the status of the red warning LEDs on active arms
sensors. The alignment is perfect if all the warning LEDs are off.
