Ultrasonic sensor
(See note below)
2. Multiple sensors (see Technical data for the maximum number) can be synchronized by connecting the synchronization inputs on the sen-
sors. The sensor interface can be used to parameterize the sensors so that one functions as a master and the others function as slaves.
(See interface description) In this case, the sensors in master/slave mode work simultaneously, i.e. in synchronization where the master sen-
sor plays the role of an intelligent external impulse generator.
3. Multiple sensors can be controlled collectively by an external signal. In this case, the sensors are triggered in parallel and operate synchro-
nously, i.e. at the same time. All sensors must be parameterized via the sensor interface so that they are set to external. See the software
description.
4. Several sensors are controlled with a time delay by an external signal. In this case, only one sensor is externally synchronized at any one
time (see note below). All sensors must be parameterized via the sensor interface so that they are set to external. See the software descrip-
tion.
5. A high signal (L+) or a low signal (L-) at the synchronization input switches the sensor to standby in the case of external parameterization.
Note:
The response time of the sensors increases in proportion to the number of sensors in the synchronization chain. In multiplex mode, the measuring
cycles of the individual sensors run in succession in a chronological sequence.
Note:
The synchronization connection of the sensors supplies an output current in the case of a low signal, and generates an input impedance in the
case of a high signal. Please note that the synchronizing device must have the following driver properties:
Driver current according to L+ > n * high level signal/input impedance (n = number of sensors to be synchronized)
Driver current according to L- > n * output current (n = number of sensors to be synchronized).
