1 General information
1.1 General information
This instruction manual contains information covering installation, initial operation as well as the applicable
communication standards of the Baumer Series 09 ultrasonic sensor family. It supplements the guidelines as
published in the installation instruction sheet which is packed with every sensor shipped.
2 Installation
2.1 Installation methods and installation suggestions
2.2 Mechanical cascading of a number of sensors
In case of a number of sensors being installed side by side (cascading) they may not be screwed down
directly touching each other. This is due to the mechanical tolerances of the sensor housings and the
possible danger of transmitting structure-born sound. The sensors must be fixed individually maintaining a
pitch of at least 9 mm.
Cascading of the Series 09 Ultrasonic Sensors without beam columnator is not recommended.

2.3 Beam columnator
Never attach a beam columnator to sensors designed for operation without beam columnator only.
Sensors with beam columnator feature extended functions (sensitivity adjustment) which are not available for
sensors without beam columnator.
Disassembling the beam columnator
In order to prevent damage to either sensor or beam columnator always turn the beam columnator first (¼
turn) before pulling it off. Never attempt to snap the beam columnator from the sensor without turning it first.
2.4 Positioning above containers (Sensors with beam columnator D1)
When measuring fill levels in micro titration plates or in similarly small containers it is imperative to align the
sensors as accurately as possible above the openings. With reference to applicable mounting distances
following reference values should be applied:

General notes
• Step 1: Setting of the sensitivity mode A-D; Step 2: Teaching of the Scanning range
• In measuring mode: Yellow LED flashing = weak signal received. Conceivable corrective measures: teach
object anew; move object closer to sensor; clean transducer.
• In measuring mode: Red LED on = object within blind range
• Provided the Teach-in sequence cannot be successfully completed the sensor defaults automatically to the
previously saved settings.
• Power must be switched off before connecting the sensors.
• A soiled beam columnator may generate erroneous output signals. Therefore it must be checked from time
to time and cleaned if necessary.
• Via the RS 232 interface measured data can be received and a number of functions are configurable.
• The sensors work with a baud rate of 115’200
3.2 Structure of commands
All commands consist of ASCII characters only. One character consists of 1 start-Bit, 8 data-Bits and 1 StopBit.
Address
Address „0“ is the broadcast address, which is accepted by every sensor and which must be used when
using RS232.
Telegram sent by the control to the sensor:
NO CHECKSUM!
Telegram (sensor response) sent from the sensor to the control:
Address 1 number 0...8,
for RS232 always 0
{0AB}
X characters
(depends on the command)

For examples refer to chapter "3.8 Examples".
