SEEN IRIS 860 Sensor Settings

This documentation covers the settings which can be configured using the SEEN Sensor Setup App.

Please also refer to How to change the sensor settings.


Settings

Critical alert zone

A detection in the Critical alert zone is indicated by a continuous audible alert tone from the sensor (and Cab Box if used). The factory setting is 3m / 10 ft, but it can be set up to 8.0m / 26ft.

Early warning zone

The Early warning zone is added on top of the Critical alert zone.  A detection in the Early warning zone (previously called ‘Pre-alert) is indicated by a beeping audible alert tone. The factory default setting is +1m / +3ft. 

The combined total of the Critical alert distance plus the Early warning distance, cannot exceed the sensor’s maximum detection distance of 8.0m / 26ft. 

Customized detection zone shape

The 60º detection fan of a SEEN sensor is broken into 6 channels. The Critical alert distance, and Early warning distance can be individually set for each channel. This can be helpful if a modified detection zone shape is required. For example, when 2 sensors are used together to provide 120º coverage, it can be beneficial to trim the two outside corners so the overall detection area is not too wide.

To customize a channel, go to the detection fan setting screen and tap to select the specific channel.. Click the controllers to adjust the distance.

Reverse Dependent Alert

By default, SEEN sensors are pre-set so they can only alert when the machine is in reverse gear. This requires the sensor to be wired to the machine’s reverse signal. There are 3 reverse dependant alert options:

  1. Sensor can only alert when the reverse signal is on (Default)

  2. Sensor can only alert when the reverse signal is NOT on

  3. Sensor can always alert (the reverse signal is ignored)

If the sensor is not wired to the machine’s reverse signal, it may not alert as intended. See how to check the reverse signal connection.

Volume

The IRIS 860 sensor features a loud piezo buzzer which emits a 3,500Hz audible tone at 94dB (at 1m). The buzzer is deliberately loud to promote behavior change, and to be clearly heard in noisy environments. Although loud, It is not harmful to hearing, even with prolonged continuous exposure. When the sensor is mounted close to the driver’s head the buzzer volume may need to be reduced.

Reducing the volume can be done in two ways:

  • In the sensor settings

  • By using a SEEN IRIS 860 Buzzer Cap (PN  SI-133)

Volume options

  • Normal volume: 94 dB

  • Normal volume with Buzzer Cap: 80 dB

  • Reduced volume setting: 85 dB

  • Reduced volume setting plus Buzzer Cap: 70 dB (not recommended)

  • OFF (use with caution)

Test Mode

If the Test Mode setting is enabled on the sensor, the machine operator can temporarily toggle the sensor into a ‘test mode’ where the SEEN sensor will temporarily ignore any Reverse Dependent setting. This is intended for use during a pre-start check, and allows the operator to check the sensor is working without putting the machine into reverse gear. 

The Test Mode toggle lasts 2 minutes. To clear Test Mode at any time, simply switch off the ignition and restart the machine as normal.

Procedure

  • When doing this test, do not start the engine or put the machine in gear. Always keep the park brake on.

  • Without starting the engine, switch vehicle ignition on and wait 2 to 5 seconds

  • Switch the ignition off

  • Switch the ignition on (again without starting the engine)

  • The sensor is now temporarily toggled into Test Mode, and can alert even when not receiving the reverse signal input

  • The operator can now enter the detection zone wearing a reflective safety vest. Detection is indicated by an audible alert tone and red LED

  • With the sensor still in Test Mode, put the machine in  reverse

  • If the reverse signal is correctly connected, the sensor alert will sound while the machine is in reverse.

Once this test is complete, turn off the ignition and then restart the machine. This returns the sensor to normal.

Sensitivity

The sensor can be set with Reduced sensitivity. When set to Reduced, the sensor requires approximately 30% more reflective material to detect than at Normal sensitivity. Reduced sensitivity can help in environments where false detections are observed. A false detection is any detection that does not come from a retroreflector. Although uncommon, the sensor may occasionally be triggered by plastic stretch-wrap and certain metallic surfaces which create a retroreflective type effect.

Accessory socket output

By default the IRIS 860 accessory socket will only output an electrical signal during a critical detection alert. The sensor can also be set to output an electrical signal in the following conditions:

  • Early warning alert (output is synced with the early warning beep pattern)

  • Internal error alert (output is synced with the internal error beep pattern)

  • Test Mode (enables output while Test Mode is active)
