The sensor has a 2-line LCD display and 4 LED indicators for ongoing indication of
sensing status: Power ON, Alarm, and Outputs 1 and 2.
In Run mode, the current measured value is displayed in the top line of the sensor’s
display, in millimeters or hundredths of an inch, as selected.
Sensing Options
Sensing Beam. The sensor uses an infrared Class 1 laser for sensing, and a visible red
Class 2 laser (or Pilot laser) for alignment. Both lasers are aimed at the identical target
spot. The laser beams are collimated to focus a compact spot, even at long sensing
distances (see Figure 2).

Password. A Password function is included to provide a measure of security for the
sensor settings. If Password is set to ON, the password must be entered before any
programming can take place. The password is always “1234”; it cannot be changed.
(The security results from the requirement to know the entry procedure and the timeout
function. If the password is not entered within approximately 10 seconds, the sensor will
return automatically to Run mode.) Measuring continues in the “background” while the
password is entered).
Select measurement in millimeters or inches (actually, hundredths of an inch. To “see”
whole inches on the display, imagine a decimal point on the display, two spaces in from
the right; see Figure 8).
Offset. An offset value can be entered or taught, which increases or reduces the measured
value, in order to compensate for a mounting position that does not correspond with the
zero point of the device. (For example, 3000 actual distance minus 1200 mm offset value
equals 1800 mm adjusted output value.) The offset value can be up to 100,000 mm (or
corresponding inch value); the plus or minus is also selectable. The offset value reverts to
0 if the factory preset function is used. The offset value applies equally to all outputs.
Factory Preset. Sensor easily reverts to factory preset conditions:
Teach-In –
Q1 and Q2 (Discrete) – single switchpoint (full sensing range), ± 5mm hysteresis
QA (Analog) – Mode 1, rising (positive slope, full sensing range)
Offset – 0
Unit – mm
Serial – RS422
Password – OFF
Multiple Outputs. The sensing distance can be taught using QuickSet, Teach-In, or by
manually entering the distance value(s). Either one or two sensing conditions may be
taught for each output (see Figures 4 and 5).
Discrete outputs: The two outputs may be configured identically or they may have
completely independent limits and configuration. One or two sensing conditions can be
taught for each. If one condition is taught, the output sets a switching threshold, around
which the selected hysteresis is applied. The two-point TEACH result differs, depending on
whether QuickSet or TEACH-IN is used to set the limits. In QuickSet, the sensor averages
the two taught values, then centers a 200 mm window around the averaged point (100
mm to each side). TEACH-IN window limits remain as taught; the window can be any
size. The selected hysteresis is applied to each threshold and window near limit and far
limit equally, no matter how they are taught.
Analog outputs: Analog limits 1 and 2 must be at least 300 mm apart. Individually teach
4 mA (A1) and 20 mA (A2) points or use the Copy function (selectable in the Analog
Output Mode menu) to copy the discrete limits (only the first limits of discrete 1 and 2) to
the analog output. (If copying Discrete limits to Analog, Discrete limits 1 and 2 must be
at least 300 mm apart, or sensor will not copy those limits.) The order in which they are
copied determines the analog output slope. For Mode 1 (positive slope) selected:
Q1, then Q2 – Limit Q1.1 becomes A1 (4 mA); Q2.1 becomes A2 (20 mA)
Q2, then Q1 – Limit Q1.1 becomes A2 (20 mA); Q2.1 becomes A1 (4 mA)
Manual Adjust: After Teach mode, Manual Adjust (or Edit) may be used to adjust the
value set for any output. It also can be used instead of Teach mode, to input a precise
limit value.

Theory of Operation
A short electrical pulse drives a semiconductor laser diode to emit a pulse of light. The
emitted light is collimated through a lens, which produces a very narrow laser beam.
The laser beam bounces off the target, scattering some of its light through the sensor’s
receiving lens to a photodiode, which creates an electrical pulse. The time interval
between the two electrical pulses (transmitting and receiving the beam) is used to
calculate the distance to the target, using the speed of light as a constant.
Multiple pulses are evaluated by the sensor’s microprocessor, which calculates the
appropriate position value. The outputs energize whenever the target is located between
the user-programmed window limits or when the preset switching threshold is crossed.
Outputs may be programmed for a variety of functions.

Alignment
Wherever the visible pilot laser spot is located, the sensing/measuring laser will be located
in the same position. For fine adjustment, use bracket model SMBLT7 with the fine-adjust
accessory kit SMBLT7F (see page 22) to provide up to ±3° angle in both X and Y axes.
Aligning the sensor manually (without the alignment aid accessory) – either model:
1. Mount the sensor.
2. Activate any Programming menu item (see Figure 7), so that the pilot laser is
ON.
3. Hold the retroreflector or target object at a short distance, for example less than
1 m (3'), and verify that the laser light spot is centered on it.
4. Move the reflector or target to its final position; verify that the laser spot is still
centered on it. Adjust as necessary.
5. Tighten the sensor mountings.
Using the alignment aid. For precise alignment of retroreflective models at long
distances, the alignment aid accessory (see Figure 9) is useful. It makes the visible pilot
laser spot easier to adjust, even when it is positioned off of the retroreflective target and at
a long distance – farther than 50 m (160').
1. Mount the sensor.
2. Mount the alignment aid on the front of the sensor, over the laser emitters as
shown in Figure 9.
3. Activate any menu item (see Figure 7), so that the pilot laser is ON.
4. Aim the sensor at the reflector.
5. Rotating the barrel as needed (depending on sensor mounting location), look into
the sight hole from about 2" (50 mm) away.
6. Turn the focus screw (opposite the sight hole) to focus the spot as sharply as
possible.
7. Adjust the sensor or target position until the laser spot is centered on the target.
8. Tighten the sensor mountings, recheck alignment; if ok, remove alignment aid.
NOTE: While alignment aid scope is in place, any measurements shown on the display will
be inaccurate. Also, the Pilot LED will be visible only through the alignment aid sight hole
(red laser light will not be visible to the naked eye on the target or another surface).

Installation Notes
Some targets (those with a stepped plane facing the sensor, a boundary line, or rounded

Serial Communications
Factory delivery status settings are underlined below.
Serial Select (RS422/SSI)
With Serial Select it is possible to select the interface from RS422-compatible,
SSI1/10-compatible, or SSI1/8-compatible connections.
RS422-/ or SSI-Compatible
Depending on the setting made in Serial Select, the appropriate interface parameters are
displayed or altered. The following settings are possible:
• RS422
Baud rate: 4.8 or 9.6 or 19.2 or 38.4 or 57.6 kBaud
Data bit: 8 or 7
Stop bit: 1 or 2
REPEAT or SINGLE: REPEAT: the sensor continuously sends measured data via the
serial interface without waiting for a request.
SINGLE mode: a string of measured data is supplied only on request.
Parity: even (but not shown on LCD menu)
• SSI: 1/10 = LSB = 0.1 mm (10MIL) or 1/8 = LSB = 0.125 mm (8MIL)
6 possible codes:
BINARY24
BINARY24E
BINARY25
GRAY24
GRAY24E
GRAY25
Serial Response Speed
The distance measurement inside the sensor is recalculated every 12 ms. It is not a
moving average, but rather a new average is calculated for the previous 12 ms of data.
With the SSI output, the data can be read every 1.4 ms (likely the “same” reading for 8 or
9 readings, then a change). For most accurate target location prediction, sample at the 1.4
ms read rate of the SSI and see “when” the change happens. Worst case, that data will be
for the average target location over the previous 12 ms, plus 1.4 ms delay (i.e., the 12 ms
average was changed just after the previous read started).

RS422 Protocol
All commands via the RS422 serial interface have the following structure:
<STX><Command><[Data]><EOT>
The sensor answers all commands as follows:
<NAK> = the command was not recognized or the data is outside
the limit values.
or
<ACK> = the command was recognized and executed; the command
requires no return data.
or
<Data> = the command was recognized and the requested data has
been sent.
RS422 Cable
The RS422 interface is defined as a reliable, serial interface in full duplex mode, with
transfer rates up to 10 MBaud; max. cable length 1,000 m (4,000'). The shielded cable is
connected to the sensor connector and the ground terminal of the control cabinet.

SSI Cable
The maximum baud rate for reliable data transfer depends on the cable length (see table).
The shielded connection cable is connected to the sensor connector and the ground
terminal of the control cabinet.
SSI Cable Length
Cable Length < 25 m < 50 m < 100 m < 200 m < 400 m

Troubleshooting; Error Codes
In the event of errors, corresponding error messages appear on the display and the error
outputs Qs and Qp (active low) are set according to the table below.
Multiple errors may simultaneously exist. The error status may be interrogated via the
RS422 “GSI” command. (For example, if a too-low supply voltage causes a counter error,
the GSI command would report “00000110”.)
