Description/Application

BS-420MG is a maritime gas alarm control panel with full

operation capabilities. All gas alarm handling and system

features can be controlled and monitored from the panel. Note

that the panel cannot be used for detection of fires.

The panel communicates with other system units on the

Ethernet-based local area network, AutroNet. The maximum

number of system units supported by AutroNet depends on the

type of system. In a standard system the maximum number is 64.

The panel can accommodate up to a maximum of 12 I/O

modules. All modules are easily plugged onto each other on a

standard mounting rail inside the unit.

The panel serves as an operating panel for one or several

defined operation zones.

The panel provides connections for 2 Ethernet ports and 2 USB

host ports.

The panel is menu operated on a 16-line display, with 40

characters per line. A printer is available as an option.

SD Card Replacement in BC-420. BS-420.

BS-430. BU-BV-420

Preparing for replacement

 Use an antistatic wrist strap

 Disconnect the mains power and battery backup

 Open the front panel

 Unscrew the 4 wing nuts, disconnect all cables (both

ribbon cables, Ethernet cable if used)

 Remove the front panel and place it horizontally on a

table with the yellow label facing upwards

 Tear of the yellow label in order to access the cut out

and the SD Card (see picture)

 Replace the SD Card (see detailed description on next

page)

 Place the new yellow label at the same location as the

previous one

 Reassemble the front panel, tighten the 4 wing nuts,

then reconnect all cables that have been

disconnected

 Close the front panel

SD SD Card Replacement in BC-440

Preparing for replacement

 Use an antistatic wrist strap

 Disconnect the mains power and battery backup

 Unscrew the 4 screws on the BC-440 unit

 Remove the BC-440 board, disconnect the network

cables, mains cable and AlCom+, plus AFB and serial

contacts if necessary

 Consult the drawings below

 Identify the version of the Controller board, either

BSA-400 or BSA-400A (see next page)

 Make sure you have the correct type of SD Card

according to the version of Controller board (see “SD

Card part numbers” on next page)

 Unscrew and remove the 6 screws on the BSF-440

board

 Gently place the board beside the unit without

disconnecting the ribbon cable

 Replace the SD Card (see detailed description on next

page)

 Re-place the BSF-440 board correctly onto the screw

pillars, then mount and tighten the screws

 Re-place the BC-440 unit, reconnect all cables that

have been disconnected, then mount and tighten the

4 front screws

 Perform a startup (see “Startup” on next page)

The operator panel controls and handles all operations, alarm management,

indications and other functions within an operation zone.

No loop driver, input or output modules can be connected to this panel.

The panel communicates with controllers and the entire system via the

Ethernet-based local area network; AutroNet.

Please specify language GB-G when ordering.

This unit serves as a connection unit for the detection loop,

alarm sounders, controls and inputs. It is a variant of the

BC-420G2 controller prepared for rack installations.

Together with the IO modules the unit will have the full

functionality of the BC-420G2 controller.

The controller is equipped with 2 Ethernet ports, one

AutroFieldBus port and one serial port. The controller

communicates with other system units using the

Ethernetbased local area network, AutroNet and external

equipment using AutroCom and Modbus. The serial port

may be set to RS-232/422 or 485 and can communicate

with external equipment using AutroCom, Modbus, NMEA

and ESPA 4.4.4.

The controller serves as a connection unit for the detection loop,

alarm sounders, controls and inputs.

The controller can accommodate up to a maximum of 12 modules.

The system offers a loop driver module for detection loops and several

types of I/O modules (see optional modules below).

A maximum of 6 loop driver modules connected to each controller. 

All modules are easily plugged onto each other on a standard mounting

rail inside the unit. The controller provides connections for 2 Ethernet

ports and 2 USB host ports, and communicates with other system units

on the Ethernet-based local area network, AutroNet.

For engineering purposes, we have established kits to be equipped

according to specifications.

The controller kit includes a cabinet with a panel front, power supply module,

communication module and text foils in a chosen language.

Additionally the cabinet can be stacked with

Loop driver module BSD-310

Loop driver module H.P. BSD-311

BS-100 loop driver module BSD-330

Output module BSB-310A

Output module BSJ-310

Input module BSE-310

Input module BSE-320

An Al_Com+ stack can contain up to six loop driver modules (BSD-3xx).

By using AutroFieldBus, an additional Al_Com+ stack (with up to six additional

loop driver modules) can be added to the system.

NOTE! The AutroSafe panels are certified with the Al_Com+ modules mounted

inside the panel cabinet.
