3 Device description
3.1 Device overview
3.1.1 IPS400i positioning sensor
The camera-based positioning sensors of the IPS 400i series enable fast and simple positioning of high-
bay storage devices in conveyor and storage systems.
• Positioning is designed for single-depth or double-depth pallet high-bay warehouses.
• Positioning in various compartment positions, e.g., rack near or rack far, is implemented with the help
of programs in the positioning sensor.
• The positioning sensor detects holes or reflectors in bars in the rack construction and determines the
position deviation in the X and Y direction relative to the nominal position.
• The position deviation is output to the control via four digital outputs or via the interface.
• Operation and configuration of the positioning sensor:
• Via the Ethernet service interface by means of the integrated webConfig tool.
• Via printed configuration codes.
The positioning sensor consists of the following components:
• Camera
• Control panel
• Lighting unit: Infrared
• Evaluation unit with the following interfaces:
• Digital I/Os
• Ethernet
The positioning sensors of the IPS 400i series are operated as a "stand-alone" single device with individual
IP address in an Ethernet topology.
The positioning sensor is optionally available with integrated heating.
Information on technical data and characteristics: see chapter 15 "Technical data".
Markings
The positioning sensor detects the following markers:
• Hole: Dark, round marking on light background
• Reflector: Light, round marking on dark background
3.1.2 Performance characteristics
The most important performance characteristics of the camera-based positioning sensor:
• Working distances 250mm to 2400mm (dependent on type/marker)
• Marker diameter 13mm to 15mm
• Typical reproducibility: 0.5mm at a working distance of up to 1900mm
• Integrated IR illumination (infrared LED, 850nm) offers high interference rejection against ambient
light.
• Intuitive alignment via four feedback LEDs and webConfig tool
• Two control buttons for intuitive operation without PC
• webConfig, a web-based configuration tool for configuration of all device parameters.
No additional configuration software necessary
• Installation wizard for simple configuration in just a few steps
• Integrated teach functions:
• Automatic adjustment of the exposure time and hole geometry
• Electronic position teach for fine adjustment
• Reading in of configuration codes
• Multiple programs

3.4.2 Function selection and program selection
Function selection
The following functions are selected and displayed via the bar graph display (see chapter 8.6 "Activating
device functions"):
•AUTO: Auto setup function for determining the optimum exposure and marker settings. Additional
teaching of printed configuration codes.
•ADJ: Adjustment function for aligning the device and for teaching-in the position in the current program
The individual functions are selected and activated with the control buttons.
• Select function with the navigation button : The function LED flashes.
• Activate function with the enter button : The function LED illuminates continuously.
NOTICE
If you activate the AUTO or ADJ function via the control buttons, the device accepts no com-
mands via the process interface. Process mode is thereby interrupted.
Program selection
The control buttons and PROGRAM display can be used to select, activate and display the first four pro-
grams that are stored in the device.

Device description
Leuze electronic GmbH + Co. KG IPS 458i 17
3.4.3 Control buttons
Function selection and program selection are controlled via the control buttons.
NOTICE
In the Service operating mode (which is set using the webConfig tool), the positioning sensor
cannot be operated using the control buttons.
•  –navigation button: Scroll through the functions in the function and program selection display from
left to right.
•  –enter button: Scroll through the functions in the function and program selection display.
NOTICE
A preselected function (flashing LED) does not yet have any influence on the functionality. If no
button is pressed for a longer period of time, flashing of the LED is ended automatically by the
device.
NOTICE
The AUTO and ADJ functions always apply to the currently valid program. Both functions must
be deactivated again by pressing the enter button .
Exiting a function mode
When exiting a function mode (AUTO/ADJ), observe the following notes:
• Short press of the enter button : The function mode is exited, the parameters are not accepted.
• Long press (3 seconds) of the enter button and teach not possible: The function mode is exited, the
parameters are not accepted.
• Long press (3 seconds) of the enter button and teach possible: The function mode is exited, the pa-
rameters are stored permanently.
Upon exiting a function mode, the four feedback LEDs signal whether teaching was successful:
• Single, brief flash: Teaching successful
• Flashing fast (3 seconds): Teaching not successful

In the "Single trigger mode" camera operating mode, the positioning sensor captures one image and at-
tempts to determine the actual position of the marker relative to the nominal position.
4.2.2 Reading gate control
Upon activation, the reading gate control opens a time window in the device for the positioning operation. In
this time window, the positioning sensor continuously determines the relative position and outputs the posi-
tion. The reading gate control must be deactivated again via the trigger signal.
The "Reading gate control" camera operating mode is activated upon shipment from the factory.
Image acquisition and evaluation occur in parallel.
With the "Sequential reading gate control" camera operating mode, image acquisition and processing of the
images occur one after another (sequentially).
4.3 Quality score
The quality score is a measure of the quality of the found marker and refers to the shape factor, the scaling
factor and the contrast of the taught marker. The quality score is output in percent [%].
Limit values can be defined in the positioning sensor via the quality score:
• Limit value at which a switching output is set as a warning if the value is less than or exceeds the limit.
• Limit value at which images are transferred via Ethernet / interface (FTP).
• In addition, the determined quality score can be output via the interface.
4.4 Offset
Offset in the X/Y direction that is taken into account for the positioning, e.g., when moving goods in and out
of storage. Here, the offset shifts the nominal position relative to the center point of the region of interest.
The offset can be in the positive or negative direction.
NOTICE
You can set one offset value per program.

4.5 Teach position
For fine adjustment and as an alternative to precise mechanical alignment, you can teach-in the position of
the device. When teaching-in the position, the coordinate system of the region of interest is placed in the
center point of the detected marker.
You can activate the function in the device as follows:
• Via the webConfig tool (see chapter 4.7 "Leuze webConfig tool")
• Via control buttons on the device (via ADJ mode)
• Via an Ethernet online command
If the teaching-in of the position fails, it may be due to the following reasons:
• The marker is not located in the device's region of interest.
• The limits of the new region of interest determined by teaching-in are not completely in the field of view.
4.6 Detection status
The detection status signals the status of the current detection:
•0: Detection successful – one marker detected in region of interest
•1: Detection not successful – several markers detected in region of interest
•2: Detection not successful – no markers detected in region of interest
4.7 Leuze webConfig tool
The webConfig configuration tool offers a graphical user interface for the configuration of the positioning
sensor via a PC (see chapter 9 "Starting up the device – Leuze webConfig tool").
The wizard of the webConfig tool can be used to easily configure the positioning sensor in just a few steps.
