BREAK CONDITION
2.
The green LED (SAFE) is OFF and the red LED (BREAK) is ON.
The status of the yellow LEDs (HIGH ALIGN, LOW ALIGN) is
different from the WAITING FOR RESTART condition. Non-
aligned light curtain condition.
Go on with the following steps to change from condition 2 to condition
1:
A
Keep the receiving unit in a steady position and set the emitting
unit until the bottom yellow LED (HIGH ALIGN) is OFF.
B
Rotate the emitting unit until the yellow LED (LOW ALIGN) is OFF
and yellow LED (HIGH ALIGN) switches ON:
C
Delimit the area in which the SAFE LED is steady through some
small adjustments - for the first and then for the second unit - then
place both units in the centre of this area.
•
Fix the two units firmly using pins and brackets.
•
Verify that the green LED is ON on the RX unit (condition where the
beams are free, SAFE) and verify that the same LED turns red if
even one single beam is obscured (condition where an object has
been detected, BREAK).
•
It is important to do this check using the specific cylindrical “Test
Piece” which presents an adequate diameter depending on the
resolution of the device used.
Note: When the Test Piece is passed from top to bottom,
throughout the entire detection area at any distance
between the two units, the red BREAK LED must always
remain ON, without false switching.
A daily test is recommended.
