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 300

to -35 °C
• Supply voltage 24VDC ±20%
• Enabling the BCL 300

through an internal temperature switch
(switch-on delay about 30 min for 24 V DC and minimum ambient temperature of
-
35 °C)
• Necessary conductor cross-section for the voltage supply: at least 0.75 mm²; the use of ready-made
cables is, thus, not possible
Structure
The heating consists of two parts:
• The front cover heater
• The housing heater
Function
When the 24 V DC supply voltage is applied to the BCL 300
i
\ BCL 301
i
, a temperature switch initially only
connects the heating to electrical power (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
BCL 300
i
\ BCL 301
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.
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.

NOTE
The mounting location is to be selected such that the it does not expose the BCL 300
