unit is visible.

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.

beam reception is below minimum level)

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.
13 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

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

Four channel frequency selection
The beam pairs may be set at various frequency
levels to avoid crosstalk between units which are
stacked, in-line, or other configurations that have the
potential of spill-over transmission from one beam to
another. Set the frequency level as indicated

choice of frequency may cause malfunction.

Beam power selection
This option allows a field selection of the appropriate
beam intensity in relation to the application. For
distances significantly below the specified protection
distance, the beam intensity should be reduced in
order to eliminate potential reflection problems. For
zones reaching the maximum protection distance, the
beam level should be set to the highest level.
For indoor applications where there is a greater
chance of reflections, the setting should be LOW.

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.
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
been set. Refer to the chart below.

2. Check beam power settings on transmitter with cover

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.

NC or NO signal output can be selected. (Contact

Environmental module
The environmental signal is initiated when the beam
reception level is reduced by approx 50% or more.
The module "watches" for a gradual degradation of
the beam reception which is indicative of extremly
poor weather conditions. NC or NO signal output can
be selected. (Contact capacity 30V (AC/DC) or less)
Alarm memory function
The alarm memory LED (Fig. 1Z) indicates which
sensor has triggered when two or more sensors are
placed in a zone.
An additional, audible sound is optional. Reset can be
automatic or manual.
