Installation & Adjustments
Adjustment
1 Mount the SGP30 unit.
Wire the sensor according to the wiring diagram.
2
Make sure the output load does not exceed 200 mA.
3 Check for correct wiring before turning power on.
4 When the power on indicator (green LED) is on the system is operating.
Use the control wire to blank any IR channels which unintended has proximity effect on
5
the output or decrease the sensing range.
6 Adjust the sensing range with potentiometer mounted in the top plastic plug of the rail.
If necessary use the control wire again to blank any IR channels which unintended has
7
proximity effect on the output.
After power on make sure that the output indicator (yellow LED) change state when an
8
object is placed in front of the rails and within the sensing range.
9 The light curtain is only intended for static applications.

Adjusting sensing range
With the potentiometer mounted in the top plastic plug of the rail the sensing range can be
adjusted from 0 m to 1,3 m. The sensing range is at its maximum when the potentiometer is
fully clock wise. Notice that when increasing the sensing range it can be necessary to blank IR
beams because nearby objects unintentionally can be detected.
Blanking function mode, Ctrl input
This function is used to blank out beams that otherwise constantly would detect close lying
surfaces or objects, for instance construction elements as metallic frames, support pillars or
beams. When an IR beam is blanked it cannot change the state of the output.
The blanking mode is activated by powering up the SGP30 with pin 2 (white Ctrl wire)
connected to ground (-). In this mode every IR beam that detects something, even temporarily,
will be blanked and stored in non-volatile memory. Pin 2 should at least be connected to
ground as long as the output indicates that one or more IR beams detects objects and the red
LED is not lit. If there are movement in close laying objects this can take some seconds.
When the blanking procedure is finish pin 2 must be removed from ground (-) before power to
the SGP30 is removed, otherwise no IR beams will be blanked. During normal operation pin 2
must be left floating. The blanking is now permanent, also after power down, until new
1,3 m
blanking has been made.
The green LED will flash three times after power-up if any IR beams are blanked.
If blanking shall be deactivated there are two options:
1. Repeat blanking process, but without nearby objects or surfaces that can cause
blanking.
2. Repeat blanking process, with the potentiometer turned to 0.

Troubleshooting

Probable Reason
1. Symptom: Status indicator (Red LED) is constant on.
SGP30 is in blanking mode and blanking
is completed.
Internal failure.
2. Symptom: Output indicator (Yellow LED) on is flashing.
Severe electrical interference.
Severe ambient light.
Cross talk from another light curtain or
photo sensor
Cross talk from a nearby HF strip light
3. Symptom: With NO output red LED, yellow LED is constant on and output is closed.
One or more IR beams have proximity
effect.
4. Symptom: With NC output red LED and yellow LED is constant off and output is open.
One or more IR beams have proximity
effect.
5. Symptom: Red LED is off and output is stocked.
SGP30 is out of sensing range.
Disposal
Disposal should be done using the most up-to-date recycling technology according to local
rules and laws.
