Verify that one of the following conditions is present on the RX unit:
SAFE CONDITION
1.
The green LED (SAFE) is ON and the red LED (BREAK) is OFF.
Both yellow LEDs (High ALIGN and Low ALIGN) are OFF.
Aligned light curtain condition.
BREAK CONDITION
2.
The green LED (SAFE) is OFF and the red LED (BREAK) is ON.
The status of the yellow LEDs is not relevant. Non-aligned light
curtain condition.
Continue with the following steps to change from condition 1 to
condition 2:
A
Keep the receiving unit in a steady position and set the emitting unit
until the bottom yellow LED (HIGH ALIGN) is OFF. This condition
shows the effective alignment of the first lower beam.
B
Rotate the emitting unit until the top yellow LED (LOWH ALIGN) is
OFF. In this condition, the SAFE LED switches ON.
Note: Ensure that the green light of the LED is ON and steady.
C
Delimit the area in which the SAFE LED is steady through some
small adjustments. 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.
