Seen IRIS 860 installation and set-up guide

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.

3. Sensor location

IRIS 860 sensors should be mounted at head height or higher

with an unobstructed view of the desired detection area. If two

sensors are used to increase the overall detection area, they

can be mounted side-by-side or spaced apart in a cross-over

configuration. Refer to the diagram below.

Detection starts 1.2 m from the sensor face.

4. Weather shield installation

• Align the sensor to the correct angle then gently tighten screw

A on both sides.

• Place the weather shield over the bracket, so the round holes fit

around the screw-heads (A) on both sides.

• Insert screw B, check the alignment and evenly tighten all

screws.

Note. It is not possible to attach a weather shield to a sensor

mounted in the ‘hung underneath’ configuration.

Weather shield

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).

8. Cab box sensor cable

A cab box sensor cable is required to connect each sensor to the

cab box. This cable supplies power to the sensor, and transmits

the detection signal back to the cab box.

To facilitate cable threading, or to shorten the cable, the larger

black plastic connector can be removed and re-wired.

IMPORTANT

When re-wiring the connector, the wire colours must exactly

match the diagram opposite. Use the screw-block as a reference.

Accessory port / cable

• 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.
