Description of the sensor functions
This ultrasonic sensor features a four-pole temperature/TEACH-IN plug, that can
be connected in four different positions. These have the following significance.
Description of the TEACH-IN procedure
TEACH-IN the evaluation limits 1 or 2
- Cut supply voltage
- Remove TEACH-IN plug
- Restore supply voltage (Reset)
- Set object to desired switching point
- Plug and remove the TEACH-IN plug in pos. A1 or A2. This teaches the evaluation limits A1 or A2.
Caution: Removing the temperature/TEACH-IN plug, the values of the object position will be adopt-
ed.
- The TEACH-IN procedure is controlled with the LED. The green LED flashes, when object is detect-
ed, the red LED flashes when no object is detected.
- Connect TEACH-IN plug in pos. T. This completes the TEACH-IN procedure and saves the dis-
tance.
- The sensor works in normal mode
TEACH-IN the analogue function
- Cut supply voltage
- Remove TEACH-IN plug
- Restore supply voltage (Reset)
- Connect TEACH-IN plug in pos. E2/E3. By multiple plugging, three different modes of operation can
be set in cyclical sequence:
1) rising ramp, LED A2 flashes,
2) falling ramp, LED A1 flashes,
3) zero line, LED A1 and A2 flash
- Connect TEACH-IN plug in pos. T. This completes the TEACH-IN procedure and saves the mode
of operation.
- The sensor works in normal mode
Note: If the temperature/TEACH-IN plug has not been plugged in within 5 minutes
in position T, the sensor will return to normal mode (with the latest permanent stored
values) without temperature compensation.
Synchronisation
The sensor features a synchronisation input for the suppression of mutual interference. If this input is
not used, the sensor will operate using an internally generated clock rate. It can be synchronised by
applying a square wave voltage. A falling edge leads to the transmission of a single ultrasonic pulse.
A low level
≥ 1 s or an open synchronisation input will result in the normal operation of the sensor.
A high level > 1 s will result in the standby mode of the sensor (indicator green LED). The outputs
pause in the latest status.
Synchronisation cannot be performed during TEACH-IN and vice versa.
Multiple operating modes are possible:
1. Two to five sensors can be synchronised by interconnecting their synchronisation inputs. In this
case, the sensors alternately transmit ultrasonic pulses.
2. Multiple sensors can be controlled by the same synchronisation signal. The sensors are synchro-
nised.
3. The synchronisation pulses are sent cyclically to individual sensors. The sensors operate in mul-
tiplex mode.
4. A high level at the synchronisation input disables the sensor.
The response time increases when the sensor is synchronised, because the synchronisation increas-
es the measurement cycle time.
Note:
If the option for synchronisation is not used, the synchronisation input has to be connected to ground
(0V) or the sensor has to be operated via a V1 cable connector (4-pin).
