Input / Output description and electrical connection

Generally the TOFniva has one output that is triggered if the detection field is interrupted. For this purpose, a push-pull
output is used. With the logic selector (gray wire, Figure 6), the logic of the output signal can be configured for "HIGH"
on object or "LOW" on object operation (Figure 5), according to the controller requirements.
The logic selection is performed during start-up.

Start-up

1. Switch on mains and power up.
2. Check if LED lights up.
3. Check the distance setting and the reaction of the sensor, including the status LED, by placing an object into the
detection area at different heights and widths.

10. LED signals

The red LED provides the sensor's status. The respective LED is dimmed when the power is OK and the detection field
is free. The LED glows bright when an object is detected and the respective output triggered. The LED is visible from the
front.
