Heating models of the bar code readers
The BCL 558
i
bar code readers are optionally available as models with integrated heating.
In this case, heating is permanently installed ex works. Self-installation on-site by the user
is not possible!
Features
• Integrated heating (permanently installed)
• Extends the application range of the BCL 558
i
to -35°C
• Supply voltage 24VDC ±20%
• BCL 558
i
enabling through an internal temperature switch
(switch-on delay about 30min for 24VDC and minimum ambient temperature of -35°C)
• Necessary conductor cross-section for the voltage supply: at least 0.75mm²; the use
of ready-made cables is, thus, not possible.
Construction
The heating consists of two parts:
• The front cover heater
• The housing heater
Function
When the 24VDC supply voltage is applied to the BCL 558
i
, a temperature switch initially
only connects the heating to electrical power (front cover heater and housing heater). During
the heating phase (around 30min), when the inside temperature rises above 15°C, the
temperature switch connects the BCL 558
i
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.
