3 Device description
3.1 General information
The light curtains of the CML 700i series are designed as measuring and object-detecting, configurable,
multi-sensor units. Depending on the configuration and model, the devices are suitable for a variety of
tasks with various resolutions and can be integrated in different control environments.
The total system of the light curtain consists of a transmitter and a receiver, including the connection and
interconnection cables.
• Transmitter and receiver are connected to one another via a synchronization cable.
• The integrated control panel with indicators and operational controls for configuring the total system
is located on the receiver.
• The shared power supply is provided via connection X1 on the receiver.

3.2 General performance characteristics
The most important performance characteristics of the CML 720i series are:
• Operating range up to 7000 mm
• Measurement field length from 150 mm to 2960 mm
• Beam spacings of 5 mm, 10 mm, 20 mm, 40 mm
• Response time 30 µs per beam
• Beam modes: parallel, diagonal, crossed-beam
• Single-beam evaluation (beam-stream)
• Evaluation functions: TIB, TNIB, LIB, LNIB, FIB, FNIB, status of beam areas 1 … 32, status of the
digital inputs/outputs
• Local control panel with display
• Interfaces to the machine control:
• IO-Link:
4 digital inputs/outputs (configurable)
• CANopen, PROFIBUS-DP, RS 485 Modbus, PROFINET:
2 digital inputs/outputs (configurable) plus IO-Link
• Analog:
2 analog current/voltage outputs plus IO-Link
2 digital inputs/outputs (configurable)
• Blanking of unnecessary beams
• Smoothing for interference suppression
• Cascading of multiple devices
• Block evaluation of beam areas
• Position / hole recognition with continuous web material

Figure 3.4: OLED display on the receiver
The type of display on the OLED display is different for the following operating modes:
• Alignment mode
• Process mode
Display indicators in alignment mode
In alignment mode, the OLED display shows the received signal level of the first active logical beam (FB)
and of the last active logical beam (LB) via two bar graph indicators.
1 Evenly aligned light curtain
2 No reception signal from first beam (FB); good reception signal from last beam (LB)
3 Marker for the minimum signal level which is to be achieved
Figure 3.5: OLED display on the receiver in alignment mode
Display indicators in process mode
In process mode, the upper line shows the number of interrupted beams (TIB) and the lower line shows
the logic state of the digital outputs. The value to be displayed is configurable.
1 Total of interrupted beams
2 Logic state at pin 2 (0 = not active, 1 = active)
3 Logic state at pin 5 (0 = not active, 1 = active)
4 Logic state at pin 6 (0 = not active, 1 = active)
5 Logic state at pin 7 (0 = not active, 1 = active)

3.4.3 Operating indicators on the transmitter
Located on the transmitter is an LED which serves as a function indicator.
If the control panel is not used for several minutes, the display darkens and switches off. Press
a function button to again make the display visible. Settings for visibility, display duration, etc.
can be changed via the Display menu.
