1.0 OVERVIEW

The Smart Laser Sensor (SLS) is a self-contained unit intended to be used to

make non-contact speed measurements from rotating targets at distances

up to 65 feet (19.8 m) or to provide non-contact reference points to balancing

equipment. Refer to Section 6.0 for an overview of operation. The unit will

output one (TTL Compatible) pulse per revolution and has the ability to

compute the RPM internally and output the ASCII values to any equipment

capable of receiving an RS232 input. For best performance use reflective

tape for the target.

3.0 QUICK START GUIDE

3.1 Slide Power switch (8) to “On”.

3.2 Rotate Sensitivity Adjust knob (7) fully counterclockwise to

the “Auto” position.

3.3 Aim the laser dot perpendicular to the target - reflective tape,

contrasting color or keyway.

3.4 If the On Target LED (1) is not on, push and hold the Red

Learn/Gain button (6) until the On Target LED (1) blinks

regularly. Note that at higher RPMs the LED will be on solid.

3.5 If after completing step 3.4, the On Target LED (1) blinks

erratically or not at all, rotate the Sensitivity Adjust knob (7)

slowly from 1 to 9 until the LED blinks regularly or is on solid.

3.6 If after completing steps 3.1-3.5, the On Target LED (1) blinks

erratically or not at all:

3.6.1 Move the sensor closer to the target and ensure it is

perpendicular to the target. Repeat steps 3.1-3.5.

3.6.2 Increase the contrast/reflectivity of the target. Repeat

steps 3.1-3.5.

3.7 Once the On Target signal is obtained, use the Polarity Switch

(5) to select a compatible output pulse for your application.

To aid in locating the laser dot over a large distance, hold a piece of white

cardboard or equivalent in front of the laser. Progressively move the white

surface closer to the desired target. Then adjust the aim of the laser as necessary.

In areas of high ambient light (outdoors), performance can be enhanced at

long distances by slipping a piece of black tube with a minimum inner

diameter of 0.6 inches, over the nose piece to act as an extension nose piece.

This tube should not deflect the beam in any way.

8.0 RS232

Baud rate = 9600, 8 bits, 1 stop bit, no parity.

When the unit is turned on, it will send out: “SLS<lf><cr>Vx.x<lf><cr>

0.0<cr>”. Where <lf> is the linefeed character, <cr> is a carriage return

character, and x.x is the firmware version number.

The unit will send out the current RPM as a right justified 7-digit ASCII

number that will always include a decimal point followed by carriage return.

The update rate is a function of the speed of the target and will not exceed

twice per second.

Examples:

1234.56<cr>

123456.<cr>

_ _ _ _0.0<cr> ( _ = space character)

Auto/Gain LED (3) will blink to show what gain has been selected. If

the button is held down, the gain will increase automatically after each

LED ‘blink’ pattern. Refer to Table 2. The larger the gain, the weaker

the signal being picked-up. Using a large gain for a strong signal is not

recommended since the input will saturate.

6.0 ADVANCED FEATURE (TARGET POLARITY)

The input circuitry can be set to optimally work with two different target

types: a reflective (white, shiny) target on a mostly non-reflective (black,

dull) background or a non-reflective (black, dull) target or a mostly reflective

(white, shiny) background. These will be referred to as a white target or a

black target. When the unit is first turned on, the On Target LED (1) will

indicate which target type the sensor is set up for. While the Laser On

LED (2) is blinking, the On Target LED will be on for a white target or off

for a black target. The unit will still work when set up for the “wrong”

target type, but it won’t have as great a range. When set for a white target,

the unit triggers on the black to white transition. When set for a black

target, the unit triggers on the white to black transition.

To change the setting, move the Polarity switch (5) to the left (positive

pulse) for a white target or to the right (negative pulse) for a black target.

Turn the Sensitivity Adjust knob (7) to Max. Press and hold the Learn/

Gain button (6) until the Auto/Gain LED (3) blinks.

7.0 AIMING THE LASER

The proper operation of the Laser Sensor is dependent upon the alignment

to and reflectivity of the target. In order to aim the beam it is necessary to

stand behind the sensor and view the target along the plane of the beam. Do

not stare directly into the laser beam or the reflected light. For targets

greater than 5 feet and up to 65 feet from the sensor, mount the laser on a

tripod using the ¼ - 20 bushing on the bottom of the unit and attach T-5

reflective tape to the target.

5.0 OPERATION

Note: Refer to Figure 1 for switch and button locations.

Turn the unit on by moving the Power switch (8) to the On position. The

unit may be operated from the internal batteries and/or the charger/power

supply. The internal batteries will be trickle charged when using the AC

charger/power supply. To turn the unit off, slide the Power switch (8) to

the Off/Charge position. If the charger is plugged in, the batteries will

charge.

The sensor emits a laser beam, which is reflected back by a target (reflective

tape/paint, keyway, contrasting colors, etc). This reflected light is sensed

and amplified then compared to a threshold level (sensitivity) - the lower

the threshold level, the more ‘sensitive’ the sensor is. Whenever the amplified

signal is above the threshold, the output goes high (positive pulse) or low

Figure 3 Pin Connections

(negative pulse). The user can select either a positive or a negative output

pulse using the Polarity switch (5).

The gain of the input amplifier and the sensitivity can be adjusted manually

or automatically. This allows the unit to be used with many types of

targets at various distances and contrasting color conditions. To select the

Auto mode, turn the Sensitivity Adjust knob (7) fully counterclockwise,

otherwise you are in the Manual mode. Reflective tape and high contrast

color applications should be able to use the Auto mode.

5.1 Auto Mode

Make sure the Sensitivity Adjust

knob (7) is fully counterclockwise

and the Auto/Gain LED (3) is on.

Aim the laser at your target. Press

and hold the Learn/Gain button (6)

until the On Target LED (1) blinks

regularly or is on solid (depending

on the RPM of the target). Release

the Learn/Gain button. The Auto/

Gain LED will blink to show what

gain has been selected. Refer to

Table 2.

In many applications, this is all that is needed. In cases where the target is

marginal, the user may need to manually adjust the sensitivity after trying

the Auto mode.

5.2 Manual Mode

Aim the laser at your target. Turn the Sensitivity Adjust knob (7)

between Min and Max until the On Target LED (1) starts blinking or

comes on solid. If you can’t get a good setting, change the gain. Press

and release the Learn/Gain button (6) to change the gain of the input

amplifier. Each time the button is pressed, the gain is changed. The
