Adjusting The Alignment - SECO-LARM SLI Enforcer E-964-D390Q Manual

Adjusting the Alignment:

The transmitter and receiver sensor units can be adjusted ±5º
vertically and ±90º horizontally once the unit is mounted and
power is connected (see fig. 2 on page 3).
There are two ways to adjust alignment:
1. Laser adjustment (see fig. 1 on page 3):
a. Remove the transmitter cover, then turn the laser on with
the ON/OFF switch (see fig. 1 on page 3). A red dot will
show where the photoelectric beams are aimed.
b. Adjust the transmitter's sensor unit vertically and
horizontally until the red dot is centered on the receiver
and both the receiver's LEDs turn off. See Table 3. It may
be necessary to adjust the horizontal and vertical angles
of the receiver's sensor unit as well.
c. Repeat steps a and b for the receiver.
d. Turn the lasers off, and then replace the covers.
WARNING: Do not look directly at the lasers.
2. Eyeball adjustment (see fig.10):
a. Remove the transmitter cover and look into one of
the alignment viewfinders (one of the four holes
located between the two lenses) at a 45° angle.
b. Adjust the horizontal angle of the lens vertically
and horizontally until the receiver is clearly seen
in the viewfinder.
c. Repeat steps a and b for the receiver.
d. Replace the transmitter and receiver covers.
NOTE – If you cannot see the opposite unit in the viewfinder, put a sheet of white paper near the
unit to be seen, move your eyes about 2" (5cm) away from the viewfinder, and try again.
Fine Tuning the Receiver:
1. Once the sensor is mounted and aligned, the sensor can
be fine-tuned using the voltage output jack.
a. Set the range of a volt-ohm meter (VOM) to 1~4 VDC.
b. Insert the red (+) probe into the (+) terminal and the
black (-) probe into the (-) terminal.
c. Measure the voltage (see table 4).
d. Adjust the horizontal angle by hand until the VOM
indicates the highest voltage.
e. Adjust the vertical angle by turning the vertical
adjustment screw until the VOM indicates the highest
voltage.
NOTE – Do not interrupt the beam while adjusting alignment.
