3.1.2 Performance characteristics
The most important performance characteristics of the bar code positioning system:
• Positioning with submillimeter accuracy from 0 to 10,000 m
• For the control at high traverse rates of up to 10 m/s
• Simultaneous position and speed measurement
• Working range: 50 to 170 mm; enables flexible mounting positions
• Interfaces: PROFINET fieldbus, PROFIBUS fieldbus, SSI, RS 232/RS 422, RS 485
• Binary inputs and outputs for control and process monitoring
• Configuration via webConfig tool or fieldbus
• Diagnostics via webConfig tool or optional display
• Optional model with display
• Optional model with heating for use to
-
35 °C
3.1.3 Accessories
Special accessories are available for the bar code positioning system. The accessories are optimally
matched to the BPS:
• Highly flexible, scratch-, smudge- and UV-resistant bar code tape
• Mounting devices for precise mounting with one screw (easy-mount)
• Modular connection technology via connection hoods with M12 connectors, spring-cage terminals or
with cable.
3.1.4 Device model with heating
The bar code positioning system is optionally available as a model with integrated heating. In this case,
heating is permanently installed ex works.
The heating consists of two parts:
• Front cover heater
• Housing heater
Features of the integrated heating:
• Extends the application range of the BPS to -35 °C
• Supply voltage 18 … 30 VDC
• BPS release through an internal temperature switch (start-up delay of about 30 min for 24 V DC and
minimum ambient temperature of
-
35 °C)
• Required conductor cross-section for the power supply: At least 0.75 mm

Function
When the supply voltage is applied to the BPS, a temperature switch initially only supplies the heating with
current (front cover heater and housing heater). During the heating phase (around 30 min), when the
inside temperature rises above 15 °C, the temperature switch connects the BPS to the supply voltage. This
is followed by the self test and the changeover to read operation. The PWR LED lights up, showing overall
readiness for operation.
NOTICE
No self-installation of the heating!
Self-installation of the heating on-site by the user is not possible.
NOTICE
Do not use ready-made cables!
It is not possible to use ready-made cables.
The current consumption of the BPS is too high for the ready-made cables.
