Resources for SEEN Safety System installers

If you are installing a SEEN IRIS 860 sensor, it is important that you follow the instructions on this page.

We recommend that you download our SEEN System Installation Guide for your reference during the installation process.

Before you start

Check that you have the components you need:

Sensor Box Contents:

  • 1 x IRIS 860 sensor

  • 1 x stainless steel mounting bracket

  • 1 x power cable 4m (13ft)

  • 4 x stainless screws (M6)

You may also need to install the following additional components. For detailed instructions, please refer to the linked resources.

Confirm location on machine

1. Confirm the mounting location

Prior to arriving on-site for the installation, ask the customer to confirm the mounting location and develop a game plan for how to mount the sensor in the required position. A custom mounting attachment may be needed to position the IRIS 860 mounting bracket in the required location.

You should mount the sensor approximately 2 metres (6.5 ft) above the ground. On a typical forklift, the best position is in the centre of the cross-bar at the top rear of the frame.

Make sure that the sensor is protected against impact. If the forklift works inside containers, ensure the sensor does not protrude above the highest point of the frame.

Mount bracket

2. Select the bracket orientation option

You can attach the universal mounting bracket (supplied) can be attached to horizontal, vertical, or angled surfaces. Select the orientation option that best suits the installation requirement. Note that the sensor retains the same orientation across all three options.

3. Bolt the mounting bracket to the machine

Securely bolt the mounting bracket to a solid surface using at least two M6 or larger fasteners (not supplied).

Over, Under, and Vertical Bracket Orientation options

Mount sensor in bracket

If a Weather Shield is used, it needs to be installed at this stage. Refer to the installation guide.

4. Check that the sensor is positioned correctly and is the right way up.

5. Align the sensor’s mounting holes with the slots in each side of the mounting bracket. 

6. Insert the 4 M6 screws (provided) and finger-tighten. 

7. Adjust the sensor to the correct angle. The figure on the alignment sticker should be upright, irrespective of the bracket’s angle or orientation.

8. Use a hex key to tighten the four M6 mounting screws to 10Nm.

*If the sensor is mounted higher than approximately 2m (6.5ft) it may need to be angled slightly further towards the ground

Wiring

If a Cab box is used it needs to be installed at this stage. Refer to the Installation Guide for more information.

9. Check the sensor voltage

Check the sensor’s maximum voltage rating sticker. It will either be 80V or 24V. If the vehicle’s power supply voltage exceeds the maximum voltage indicated on the sticker, a DC/DC voltage converter must be used. Refer to the Installation Guide for more information.

10. Wire in the Sensor Power Cable

IMPORTANT. Ensure the vehicle is turned off before starting work.
The 4m (13ft) Sensor Power Cable (supplied) must be connected to the vehicle’s electrical system.

All three wires must be connected:

  • Brown = DC power. The Brown wire must continuously receive DC power when the vehicle is switched on. A DC/DC voltage converter may be needed.

  • Blue = vehicle ground.

  • Black = vehicle direction signal. In most cases this is the reverse signal. The reverse signal must be continuously high (not pulsed) while the vehicle is in reverse gear. DC 3.5-100V.

11. Connect the M12 plug to the sensor’s 5-PIN M12 power socket. Finger-tighten only.

Test

12. Check the sensor angle

The face of the sensor should be angled slightly downwards so that the figure on the alignment sticker is upright.

13. Check the power supply

Switch the vehicle on. The sensor LED should be a steady green.

14. Test functionality

When detecting the sensor will emit a loud audible alert tone and the LED will be red.

  • Place a reflective safety vest (or other reflective item) in the sensor’s detection zone (approximately 2-3 meters from the sensor). The sensor should not alert.

  • Now, put the vehicle in reverse gear and repeat the test. This time the sensor should alert. 

The sensor LED should be green whenever the vehicle is switched on.

IRIS 860 settings 

The IRIS 860 sensor is preset with factory default settings which include the detection zone, direction based signalling and alert volume. It is the onsite Manager’s responsibility to make decisions about the sensor settings that best suit the specific work environment, and to change the settings if required, using SEEN’s setup app.

If you have been instructed to change the settings, you will need to liaise with the onsite Manager, and refer to the How to change the sensor settings guide.

Trouble shooting 

1. The sensor LED is green, but the sensor will not alert.

Possible cause: The reverse signal is not connected. By default the sensor is set so it can only alert while receiving a direction signal (usually reverse) from the machine.
Solution: Ensure that all 3 wires on the sensor (or Cab Box) power cable are correctly wired to the machine’s reverse signal, power, and ground. 

Possible cause: The retroreflective material is too close to the sensor.
Solution: Move further back. Detection starts 0.8m /2.6ft from the sensor face. 

Possible cause: The retroreflective material is worn out or is of insufficient size to enable detection.

2. A sensor that is pre-set to only alert during reverse, will alert when the vehicle is not in reverse.

Possible cause: The reverse signal input wire is twisted together with the ignition power wire, meaning the reverse signal is always high.

Solution: Ensure that the 3 wires on the sensor (or Cab Box) power cable are correctly wired to the machine’s reverse signal, power, and ground. 

3. The sensor and/or Cab Box are correctly wired but the sensor/s do not behave in the expected way.

Possible cause: Electrical earthing issue on the reverse signal.

Solution: Check that the ground reference on the reverse signal is the same as the ground reference on the sensor power supply. Refer to full Installation Guide for more information.

4. The Cab Box is correctly wired but the sensor/s do not behave in the expected way.

Possible cause: The Cab Box is wired to the machine using the 5-PIN sensor power cable, instead of the 4-PIN cab box power cable supplied with the cab box.

Solution: Use the 4 PIN Cab Box power cable supplied with the Cab Box. Do not use the 5 PIN sensor power cable supplied with each sensor.

5. The sensor repeatedly beeps and flashes with the sequence long-short-short, long-short-short.

Cause: Blocked window.

Solution: Clean the windows and the self-check alert should cease. If the sensor is operating in a cold-store freezer, ice on the window maybe triggering the self checking function. Refer to the Internal Self Check section in the Installation Guide.

6. The sensor is beeping and flashing and the sequence is NOT long-short-short, long-short-short.

Cause: Internal fault detected.

Solution: There are no user serviceable parts. Contact your supplier for repair or replacement.

7. At start-up the sensor gives a continuous tone alert when the vehicle is in gear.

Cause: Test Mode may be enabled and has been inadvertently activated. Refer to the full Installation Guide for more information.
