Factory Setting

Reset Sensor to Factory Settings
The sensor has a feature to reset to factory settings
1. Disconnect the sensor from power supply
2. Press and hold one of the Programming Buttons T1 or T2
3. Connect Sensor to power supply (red and yellow LED flash simultaneously for 5 s then green and yellow LED flash simultaneously)
4. Release Programming Button
The sensor now operates with default factory settings.

Synchronization
This sensor features a synchronization input for suppressing ultrasonic mutual interference ("cross talk"). If this input is not connected, the sensor
will operate freewheeling using internally generated clock pulses. It can be synchronized by applying an external square wave or by means of
appropriate programming via the serial interface. Each falling edge of the synchronization pulse triggers transmission of a single ultrasonic pulse.
If the synchronization signal remains low for 1 second, the sensor will revert to normal operating mode. Normal operating mode can also be
activated by opening the signal connection to the synchronization input.(See note below)
If the synchronization input goes to a high level for > 1 second, the sensor will switch to standby mode, indicated by the green LED. In this mode,
the output(s) will remain in the last valid output state. When using the external synchronization feature, please refer to the software description.
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 cordset (4-pin).
The synchronization function cannot be activated during programming mode and vice versa.
The following synchronization modes are possible:
1. Several sensors (max. number see technical data) can be synchronized together by interconnecting their respective synchronization inputs.
In this case, each sensor alternately transmits ultrasonic pulses in a self multiplexing mode. No two sensors will transmit pulses at the same
time. (See note below)
2. Several sensors (max. number see technical data) can be synchronized together by interconnecting their respective synchronization inputs.
Due to programming via the sensors interface one sensor acts as a master device, all the others as slave devices. (see description of the
interface) In this master / slave mode the sensors are triggered in parallel and are synchronized by a common synchronization pulse, provided
by the master device.
3. Multiple sensors can be controlled by the same external synchronization signal. In this mode the sensors are triggered in parallel and are
synchronized by a common external synchronization pulse. All sensors must be parameterized for external synchronization by means of the
sensor interface. See software description.
4. A separate synchronization pulse can be sent to each individual sensor. In this mode the sensors operate in external multiplex mode. (See
note below). All sensors must be parameterized for external synchronization by means of the sensor interface. See software description.
5. A high level (+U ) or a low level (-U

synchronization.
Note:
Sensor response times will increase proportionally to the number of sensors that are in the synchronization string. This is a result of the
multiplexing of the ultrasonic transmit and receive signal and the resulting increase in the measurement cycle time.
Note:
The sensors syncronization input delivers an output current in case of low level and burdens with its input impedance in case of high level. Please
pay attention that the synchronizing device needs to have that driver capability:
driver current against +U  n * high-level/input impedance (n = number of sensors to be synchronized)
