on the wall veers from the centre of the desired detection area 1 m
(3.3 ft.) from the ground, then loosen the base fixation screws (Fig.
) and use the three adjustment screws in the base to realign it to the
centre, as shown in Fig. c B. When the spot is correctly realigned,
retighten the base fixation screws.
5. Remove the alignment tool and replace the cover.
6. Carry out the walk test. Make sure that the red LED is On after the
walk test.
B. Without the alignment tool (fig. j, back cover)
1. Insert the mirror blinders in order to ensure that the detector is in
single-curtain mode.
2. Put J2 to On and wait until both LEDs are Off.
3. Walk in front of the detector across the field of view at normal speed
(without pausing) and at the maximum possible range. When you enter
the beam, both LEDs will start to blink simultaneously.
After crossing the beam, if:
1. The red LED is On (fig.
2. The red and yellow LEDs are blinking simultaneously then the
field of view is obstructed and is insufficient to verify an alarm.
There are two options:
If the blinking started near the end of the detection area, you need
to align the beam to the left (fig.
If the blinking started near the start of the detection area, you need
to align the beam to the right (fig.
Loosen the base fixation screws (fig.
screws in the base to realign the beam to the centre, as shown in fig.
c B. When the beam is correctly realigned, retighten the base fixation
screws.
4. If the LEDs do not blink, the curtain is outside of the detection range
j
(fig. D) . Walk across the beam at a shorter distance to try to
detect it.
5. Redo the walk test to confirm that the detector is correctly aligned.
6. Put J2 to Off.
Note 1: If the CLM is On, the alarm output is activated.
Note 2: It is recommended to place the cover on the detector during the
CLM walk test.
WARNING! Do not look into the laser beam.
The output power is less than 1 mW. Consequently the
VE710 laser is classified by IEC60825-1 as a Class 2
laser. The eye's blinking reflex is fast enough to prevent
any permanent damage to the eye.
