AR3000 User’s Manual

Rev 1/10
Do not point the pilot laser at any person, particularly a person’s eyes or face.
Do not attempt to disassemble the sensor.
Improper disassembly will destroy the optical
alignment of the sensor and necessitate factory repairs.
Do not operate the sensor in areas where the sensor case is exposed to direct sunlight for
extended periods or where the air temperature is more than 60
C (140
F) or less than -40°C
(-40°F).
Avoid excessive vibration and shocks
. The sensor contains securely mounted but precisely
aligned optical components.
Do not scratch the lenses on the front face of the sensor.
Keep the lenses clean with expert
optical procedures. The lenses are glass with an anti-reflection coating. Avoid the use of organic
cleaning solvents.
Do not touch the lenses with bare fingers
. The oils are very difficult to remove.
Operate only with DC supply voltages up to 30 volts.

Definition of Terms
Sensor – The complete AR3000 measurement device.
Target – The object of measurement. The relative distance from the sensor to the target is
measured by the sensor.
Laser, Laser beam – This light (infrared measurement laser or visible pilot laser) is emitted from
the sensor, reflected from the target, and collected by the camera lens.
<Range> – The maximum relative distance measurable by the sensor.
Range – 1. <Range>, 2. The region over which the target can be measured. At the near end of the
range the sensor measures zero. At the far end of the range the sensor measures its
maximum value (its Range value).

Quick Start Instructions
This will get the sensor running in its factory default configuration after selecting a measurement
mode. For full instructions use the individual sections of this manual for mounting, power
connections, data connections and configuration.
Only one output type (Serial or Analog) is needed to indicate sensor operation.
1.3.1.
Mounting and Power connection
Mount the sensor in such a way that the case is not twisted or warped. Use three screws
through M4 X 6 threaded mounting holes on the sides or bottom of the AR3000 sensor. The
laser should be aimed at a target such that the distance from the sensor face to the target can
be measured.
Attach the cable’s 12-pin connector to the plug on the rear of the sensor while the power is
off.
Connect the (Blue) and Ground (Gray/Pink or alternate Tan in some cables) wires
of the sensor cable to a 10 to 30 volt DC power supply (or use the sensor’s power supply if it
came with one).
