Function

Synchronization

The sensor features a synchronization input for the suppression of mutual interfer­ence. It can be synchronized by applying a square wave voltage. The falling edge
of a synchronization pulse at the synchronization input starts a measuring cycle. A
low level > 1 s or an open synchronization input will result in the non-synchronized
normal operation of the sensor. A high level at the synchronization input disables
the sensor. Synchronization cannot be performed during TEACH-IN and vice versa.

Two operating modes are possible:

1. The sync. inputs of 2 ... 5 Sensors are connected with each other. The sensors synchronize them­selves and operate cyclically (multiplex mode).

2. Multiple sensors can be controlled by the same synchronization signal. The sensors are synchro­nized.

3. The synchronization pulses are sent cyclically to individual sensors. The sensors operate in mul­tiplex mode.

In case of synchronized operation, the response time of the sensor increases due
to a longer measuring cycle time caused by synchronization.

Note:

If the option for synchronization is not used, the synchronization input has to be con­nected to ground (0V) or the sensor has to be operated via a V1 cable connector
(4-pin).

Setting the switching points

The ultrasonic sensor features a switch output with two teachable switching points.
These are set by applying the supply voltage -UB or +UB to the TEACH-IN input.
The supply voltage must be applied to the TEACH-IN input for at least 1 s. LEDs
indicate whether the sensor has recognised the target during the TEACH-IN proce­dure. Switching point A1 is taught with -UB, A2 with +UB.

Five different output functions can be set:

- Set object to near switching point

- Teach switching point A1 with -UB

- Set object to far switching point
