Safety regulations

Observe the locally applicable legal regulations and the rules of the employer's liability insurance association.

Qualified personnel

Mounting, commissioning and maintenance of the device must only be carried out by qualified personnel. Electrical work must be carried out by a certified electrician.

Attention Laser Radiation!

WARNING: The bar code reader BCL 21/22 SB operates with a blue light laser of class 2 acc. to EN 60825-1. If you look into the beam path over a longer time period, the retina of your eye may be damaged!

Never look directly into the beam path!

Do not point the laser beam of the BCL 21/22 SB at persons!

Safety Notices

When mounting and aligning the BCL 21/22 SB, take care to avoid reflections of the laser beam off reflective surfaces!

Heed the laser safety regulations according to DIN EN 60825-1 in their most current version! The output power of the laser beam at the reading window is at most 1.8mW acc. to (DIN) EN 60825-1.

The BCL 21/22 SB uses a laser diode with low power in the visible blue light range with an emitted wavelength of 405 nm.

CAUTION - the use of operating and adjusting devices other than those specified here or carrying out of differing procedures may lead to dangerous exposure to radiation!

BCL 21/22 device construction

Figure 3.1: BCL 21/22 device construction

3.1 The bar code readers BCL 21/22

The bar code readers BCL 21/22 are high-speed scanners with integrated decoder for all bar codes currently in use, e.g. 2/5 Interleaved, EAN etc.

The many possible configurations allow the adaptation of the device to a multitude of reading tasks. Due to the small dimensions, the BCL 21/22 may also be used in highly constrained spaces. The low weight permits the installation into machines that were not designed for heavy components. The various beam exits (perpendicular/front side) extend the area of application of the BCL 21/22 and help it to adapt.

The connector units MA … offer simple electrical installation in conjunction with the BCL 21. Information on technical data and characteristics can be found in chapter 4.

BCL 22 "stand alone"

The bar code reader BCL 22 is operated as a "stand-alone" device on the RS 232 interface. The BCL features a cable for the electrical connection of the supply voltage, the interface, and the switching inputs.

BCL 21 with MA2/MA 4…

If several BCLs are to be networked, the use of a connector unit MA 2/MA 4… is recommended for each BCL 21 with RS 485 interface. Electrical connection, commissioning, and service can be comfortably carried out in a short period of time. BCL 21 and MA 2/MA 4… are arranged separately. The two devices are connected by a cable.

3.1.1 Networking

Up to 30 scanners can be networked via the connector unit MA 2 and a bus master MA 30/31. For this, every BCL 21 is assigned its own hardware address in the corresponding MA 2. The devices are networked by connecting the individual RS 485 interfaces in parallel.

multiNet plus

In the Leuze multiNet plus, the individual network devices sequentially transfer their data to the network master MA 30/31 when requested. In addition, every bus node declared a slave receives a device address which is adjusted in the corresponding MA 2/MA 4… via a coding switch. The device address remains in the MA 2/MA 4… when the scanner is replaced.

The master then transmits the data of all network devices via its host interface to a primary PLC control system or a computer, i.e. it "collects" the scanner data in the network and transmits them to an interface on the host computer. This reduces interface costs (CPs) and time spent programming the software.

Networking via multiNet plus

Figure 3.2: Networking possibilities using the multiNet plus (BCL 21)

10 Technical description BCL 21/22 SB Leuze electronic

Description

Two-wire RS 485

The Leuze multiNet plus is optimized for fast transmission of scanner data to a primary host computer. The multiNet plus consists physically of a two-wire RS 485 interface through which the multiNet plus software protocol is controlled. This makes wiring the network easy and inexpensive as slaves are connected to one another in parallel.

Interface modules

Shielded, twisted pair conductors should be used for the multiNet. This allows a total network length of up to 1200 m. Connection of the network to the primary computer is made via the host interface of the MA 30/31 which can be equipped with 4 different physical interface modules. The available options are modules for RS 422, RS 232, TTY or RS 485.

Fieldbus connection

The MA 2xxi connector unit (see chapter 5.1 "Accessories") is available for connecting the BCL 22 to all common fieldbus systems.
