unit is visible.
- Repeat the procedure for the lower optical unit, then
repeat on receiver.

Initial beam alignment can be achieved by using the
alignment tone indicator.
- Attach the shading plates (located at the sides of
both TX / RX) to the lower optics of both TX and RX.
- Turn the receiver alignment tone switch to ON.
- Adjust the optics with the adjustment screws until
the highest tone is reached. (Note: There will be no
sound if the attenuation alignment tone LED lights
up.)
- Reverse the procedure, i.e. attach shading plates to
upper optics of T / R and repeat adjustment.
- After the adjustment, replace the shading plates in
the retaining areas of TX / RX.
- Turn the alignment tone indicator to OFF.
12 E - Sensitivity attenuation LED (lights up when
beam reception is below minimum level)
12 F - Alignment tone switch
12 G - Monitor jack
Beam alignment using voltmeter
Precise alignment can be achieved by using a
voltmeter (10VDC). Connect the leads from the
voltmeter to the monitor jacks of the receiver. The
measurings for alignment are as follows.
12 H - Voltmeter (10VDC)
Voltage reading
2.7V or more
2.0V to 2.7V
2.0V or less Poor, re-adjust
Attach cover
- Attach transmitter cover first.
- Confirm that receiver sensitivity attenuation LED
remains OFF. Place cover in position, but do not
secure. A "beep" sound will occur after five seconds.
After this signal, secure the receiver cover with
screws.
Sensitivity allowance is automatically set when
the beep sound is initiated.
If the sound alignment switch is left ON
accidentally, the sound will cease when the
receiver cover is attached.
- If there is a continous "beep" sound, detach the
receiver cover and re-adjust it, referring to the
auto-gain lock function.

Operation check

13
After installation, alignment and auto-gain set, test
operation by a walktest of the beam. Two methods
may be used:
Alarm LED only.
Alarm LED and sound check by means of the sound
alignment switch. If the sound alignment switch is
set to "ON", the sound will stop when the cover is
replaced but be effective for an audible operation
test for five minutes after the auto-gain is locked.

Functions description

Auto-gain lock function
The auto-gain lock serves to standardize the
responsiveness and tolerance level of the units,
regardless of the varying distance in an installation.
- The situations in
tolerance and responsiveness levels although the
distances differ.
OFF A "beep" sound is issued from the receiver
approximately five seconds after the cover is put into
position. This sound indicates that the auto-gain has
0.7 sec.
been set. Refer to the chart below.

1. Beam is interrupted once cover is replaced.
2. Beams are misaligned and sensitivity
attenuation LED lights up.
1. Remove any obstacle. Ensure that the hand does not
interrupt the beam when holding cover in temporary position.
A sound is generated regardless whether the
"beep" (alignment sound) switch is set to ON or
OFF.
The auto-gain setting is locked even if power is
disrupted.
When the receiver cover is detached while power
is supplied, the auto-gain is automatically reset
to maximum sensitivity.

Response time changeover function
This feature can be used to alert the response time of
the beam to best fit the application. Use the 0.7sec
setting with caution. Non-detection of fast moving
human being could result.
Alarm output
NC or NO signal output can be selected. (Contact
capacity 30V (AC/DC) or less.)
Alarm memory function
The alarm memory LED indicates which sensor was
triggered when two or more sensors are placed on a
zone.
Reset can be automatic.
