1. Overview
Seen IRIS 860 infrared laser sensors have a 60º horizontal x 45º
vertical detection area, and are designed to detect retroreflective
material such as the reflective tape on day/night high visibility
safety vests and markers.
The maximum detection range is 8 metres. The minimum
detection range is 1.2 metres. Detection is indicated by a loud
continuous-tone audible alert.
Sensor settings such as detection distance, volume, direction,
and test mode, can be configured using Seen’s simple PC
configuration app. Refer to Section 10.
IRIS 860 sensors are designed for use on industrial mobile
equipment in indoor and outdoor environments. They can also be
attached to fixed infrastructure to monitor exclusion zones.
2. Mounting bracket
The supplied stainless steel mounting bracket can be attached to
horizontal, vertical, or sloped surfaces. Securely bolt the bracket
to a solid surface using appropriate fasteners.
Once mounted, the sensor should be adjusted in the bracket so it
angles downwards by approximately 27º from horizontal (refer to
the diagrams below).
Tip: In mounting scenarios A and B, the front face of the sensor
should be parallel to the front edge of the bracket as shown by the
dashed lines.

5. Sensor electrical connection
If the sensor will be connected to a cab box, skip to section 6,
‘Cab box electrical connection’.
The supplied 2 metre power cable has a 5-pin M12 connector at one
end which attaches to the sensor, and bare wires at the other end
for connection to ignition power, ground, and reverse signal.
When powered up the sensor will beep once and the LED will flash
red then glow green. Detections are indicated by a continuous alert
tone and red LED.
Note: To minimise irrelevant detections, a connection to the reverse
signal allows sensors set to ‘R’ (reverse) to alert only while the
machine is reversing. A forward facing sensor can be set to ‘F’ and will
only alert when the machine is not reversing. Refer to section 10 for
more information about the config settings.
Note: If the BROWN (ignition) and BLACK (reverse) wires are twisted
together so they both receive 12-24V ignition power, an ‘R’ set sensor
will alert in any context.
TROUBLE SHOOTING. If an ‘R’ set sensor appears correctly
powered and connected to the reverse circuit but does not detect
as expected, please refer to section 7: Trouble-shooting the
reverse signal input into an IRIS 860 sensor or cab box.

6. Cab box electrical connection
Seen’s cab box provides an audible detection alert and LED
indication to the driver inside the cab. Up to four sensors can be
connected to a cab box.
The cab box is powered by a 4-pin M12 power cable (supplied)
which is wired to the machine’s ignition power, ground, and
reverse signal (optional).
Note: To minimise irrelevant detections, a connection to the reverse
signal allows sensors set to ‘R’ (reverse) to alert only while the
machine is reversing. A forward facing sensor can be set to ‘F’ and
will only alert when the machine is not reversing. Refer to section 10
for more information about the config settings.
TROUBLE SHOOTING. If an ‘R’ set sensor attached to the cab
box appears correctly powered but does not detect as expected,
please refer to section 7: Trouble-shooting the reverse signal
input into an IRIS 860 sensor or cab box.

7. Trouble-shooting the reverse
signal input into an IRIS 860 sensor
or cab box
Applies to: Sensors requiring a reverse signal input to indicate
when to alert. Cab boxes connected to the reverse signal.
Problem: The sensor / cab box appears correctly powered and
connected to the reverse signal, but the sensor does not alert
when the vehicle is in reverse.
Cause: The sensor’s reverse signal detection circuit is not
registering the reverse signal input. This is most likely caused by
a grounding issue.
How to check the reverse signal
• Unplug the sensor / cab box from its power cable
• Switch the vehicle ignition to ON (preferably without starting
the vehicle for safety)
• Attach a voltmeter across the Ignition power pin (+) and the
Ground pin (–) of the power cable. The voltage should be
between +10V and +30V. Refer to the Sensor / Cab box power
cable diagram (opposite)
• Next, attach the voltmeter across the Reverse pin and the
Ground pin (–). When the vehicle is NOT in reverse the voltage
should measure between 0V and +1V. When the vehicle IS in
reverse it should measure between +3V to +100V.
If the vehicle is in reverse and the voltage is not 3-100V between
the Ground pin (–) and the Reverse pin, there may be a grounding
issue.
DC/DC converter grounding issue
Some installations (typically electric machines) require a DC/DC
converter to reduce the supply voltage to 12 or 24V. If the DC/
DC converter is an isolated type, the ground reference for the
sensor’s power supply can be dierent from the ground reference
for the reverse circuit.
The DC/DC converter circuit diagram (opposite) will not work
because the reverse signal input is isolated from the IRIS 860
sensor ground (-Vin on the IRIS 860 sensor)
Making a connection across the DC/DC converter isolation barrier
(shown as the dashed ‘jumper’ line) means all the circuits now
have a common ground. HOWEVER this is not advisable if other
accessories also use the DC/DC converter because the isolation
barrier may be required for safety. In this case the best solution is
to use a separate DC/DC converter for the IRIS 860 sensor with
the jumper line connected as shown.
Note. To check if an ‘R’ set sensor is working correctly, supply 12-
24V to both the ignition wire (brown) and reverse wire (black). A
properly functioning sensor wired in this way will always be active
and trigger o a reflective vest. (Note the 1.2m minimum operating
range when testing).

• The IRIS 860 accessory power supply is used to power the camera
accessory (maximum supply current 500mA)
• Detection 12V puts 12V on the camera trigger during detection (this is a
low power output and can only sink/source a few milliamps of current).
• If required, add an external regulator to limit the 12V detection logic
output voltage (e.g. down to 5V or 3.3V) or use Detection 3V6 (black) for a
3.6V detection output.
Also refer to section 15 for the Accessory Port PIN-out diagram for full
electrical specifications.

10. Sensor config settings
IRIS 860 sensors are supplied with a default setting which is
indicated on the config sticker on the back of each sensor.
These settings can changed using a simple PC desktop software
application which can be downloaded for free at
www.seensafety.com/download
An IRIS 860 USB config cable is needed to connect the sensor’s
power port to the computer’s USB port.
Instructions
• Launch the IRIS 860 software app (Windows PC required)
• Connect the config cable USB plug directly to the computer
USB port, THEN connect it to the sensor power port
• The sensor will power up (indicated by green LED). Wait a few
seconds for the sensor to boot (indicated by a brief change to
red LED) and once booted, click “Connect”
• Update the settings then click “Apply New Settings”
• Check the new settings are correct, then unplug the sensor and
repeat for the next sensor.
TROUBLE SHOOTING.
• Make sure the sensor finishes booting (red LED followed by
steady green LED) before clicking “Connect”.
• If the sensor is powered on (green LED) but fails to connect,
try installing the Windows drivers included with the software.
Range setting
The detection range can be set in 0.5 metre steps up to 8.0
metres. Select Custom Range to individually change the range of
each channel (see examples on the following page).
Direction setting
A Reverse (R) set sensor will only alert in the presence of a 12-
100v reverse signal from the machine. A Forward (F) set sensor
will only alert when a reverse signal is not present. An Always
(A) set sensor will alert even if it is connected to a reverse signal
input.
Test Mode setting
A Test Mode enabled sensor can be temporarily toggled to test
mode using a simple ignition on-o-on sequence. When test mode
is active, the reverse direction (R) setting is ignored for 2 minutes.
This allows an operator to walk behind the machine to test the
sensor/s function without the machine needing to be in reverse
gear.
Test procedure:
• Turn the ignition on (to power the sensor), wait 2 to 5 seconds,
then turn the ignition o. The next time the ignition is turned
on the sensor will be in test mode indicated by a flashing green
LED on the sensor and cab-box (if used).
• Test mode lasts 2 minutes. The green LED on the sensor and
cab box (if used) flashes during this period indicating test mode
is active.
• Check the sensors are working by walking into the detection
zone behind the machine wearing a reflective safety vest.
Detection is indicated by an audible alarm and red LED.

• Return to the cab and engage reverse gear to test the reverse
signal. The audible alarm should sound when the reverse signal
is detected.
• The test is now complete. Turn the ignition o, restart the
vehicle and operate as normal.
• To clear test mode at any time simply switch the ignition o,
then re-start the machine.
Sensitivity setting
Reduced sensitivity mode may help in environments where
false detections are occurring. False detections are defined as
detections which do not come from a retroreflector. Although
uncommon, the sensor may occasionally be triggered by plastic
stretch-wrap in certain conditions, and from certain metallic
surfaces which create a retroreflective type eect. Low sensitivity
mode slightly increases the amount of retro-reflective tape
required to enable detection, and may prevent some false
detections.
Volume reduction
This setting reduces the alert tone from very loud to loud. It can
be used in situations where the sensor is close to the operator
and the alert tone is uncomfortably loud. The 3.5kHz alert tone is
94dB at 1 metre.

11. Self checking function
IRIS 860 sensors have an automatic self checking function that
can alert the operator of an internal fault, or if the laser transmit
window becomes excessively contaminated and needs cleaning.
If the sensor LED (and cab box if used) repeatedly flashes red
and beeps, the sensor is indicating a fault. Stop the machine.
Try cleaning the sensor windows (see below) but if this does not
correct the issue, please contact your Reseller/Supplier or Seen
Safety to arrange repair or replacement.
12. Sensor maintenance
There are no user-serviceable parts in the sensor. Other than
keeping the windows and buzzer free from dust and dirt build-
up, no scheduled maintenance is required. Remove dust and dirt
using clean water and a clean non-abrasive cloth. The sensor and
buzzer are rated IP67 (protected from dust ingress and water
ingress at 1 metre submersion for 30 minutes). Do not use high
pressure water jets to clean.
13. Warranty
Seen IRIS 860 sensors have been designed for reliable long-term
use on industrial vehicles in both indoor and outdoor applications.
Seen oer a 1-year repair or replacement warranty on materials
and workmanship. The warranty excludes general wear and tear,
physical damage caused by direct impact to the sensor, damage
to the windows, damage caused by high-pressure water jets, or
incorrect electrical connection. There are no user serviceable
parts. Opening the sensor will void the warranty.
