3.1.3 Accessories
Ideally matched accessories for the bar code positioning system:
• Highly flexible, scratch-, smudge- and UV-resistant bar code tape
• Mounting devices for precise mounting with one screw (easy-mount)
• Connection hood with M12 connectors or spring-cage terminals for modular connection technology
3.1.4 Device models with optics 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 24 VDC
20%
• BPS enabling 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 24 VDC 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.
When the inside temperature reaches approx. 18 °C, another temperature switch turns the housing heater
off and, if necessary, back on again (if the inside temperature drops below 15 °C). This does not interrupt
the read operation.
The front cover heater remains activated until an inside temperature of 25 °C is reached. At temperatures
above this, the front cover heater switches off and, with a switching hysteresis of 3 °C, back on again at
an inside temperature below 22 °C.

Connection technology
For the electrical connection of the BPS, the following connection variants are available:
• MS 348 connection hood with M12 connectors
• MK 348 connection hood with spring-cage terminals
The voltage supply (18 … 30 V DC) is connected acc. to the connection type selected.
2 freely programmable switching inputs/switching outputs for individual adaptation to the respective appli
-
cation are also available here.
3.2.1 MS 348 connection hood with M12 connectors
The MS 348 BPS connector hood features three M12 connector plugs and a Mini-B type USB socket as a
service interface for configuration and diagnostics of the BPS.
NOTICE
No self-installation of the heating!
Self-installation of the heating on-site by the user is not possible.
NOTICE
No 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.
