System description & Application examples 2 System Description


2 System Description

2.1 OverviewThe Salwico Gas Detection System (Salwico GDS) is a state-of-the-art, control andsupervision system designed to meet marine, industrial and transport requirements.It consists of different modules and software together with a number of Gasdetectors. The modules from the CCP Platform are used to build supervisionsystems and the software determines how the system will react in case of a gasindication from gas detectors or from an input that can generate alarms. Thesoftware continually supervises the system and will alert in case of anymalfunction.

The system has five different alarm levels:

• Gas alarm level 2

• Gas alarm level 1

• Gas, pre-alarm

• Fault

• Warning

NOTE!This description is based on the software release 1.0.0.

2 System Description System description & Application examples


Figure 1. Cabinet LNG GDS

Thanks to the modular design both large and small systems can be designedwithout sacrificing the simplicity for the user.

Figure 2. Some Control Panels, Modules and Gas Detectors in the Salwico Gas Detection System(Salwico GDS).

2.2 System Software

2.2.1 Main layersThe system software conceptually has three different layers; a presentation-, acontrol/process- and a module/field layer.



Figure 3. Overview of the software in a Control Module Gas

2.2.2 Presentation layerThe control and supervision of the system is done by a Human/Machine Interface(HMI) which exchanges the physical topology of the system for a logical topology(zones and logical addresses). This layer serves, controls and formats the data forcommunication with the user.

NOTE!Gas sensors are assigned to a zone and a logical address by the definition program.Zone and the address are used when the system interacts with a user and when afault or alarm appears. One zone can contain one or several gas sensors!

2.2.3 Control/Process layerThis layer holds a model of the system. It handles data from the:

• configuration, the modules and gas detectors expected by the system

• field layer, actual status collected from the modules

The system model is used for supervising system data and accepts request forstatus change by the:

• HMI layer, supervision and status requested by the HMI, e.g. mute/reset

• logic solver, supervision and status requested by the logic solver, e.g. setting anoutput

• external protocols, supervision by the MODBUS and NMEA protocols



2.2.4 Module/Field layerThis layer consists of the modules that are connected to field devices (gas detectorsand the I/O) in the system. The modules in this layer are responsible for collectingdata from and evaluating alarm and fault conditions for the field devices.

2.2.5 Access levelsThe user has access to the system via the Control Panels but the HMI has fouraccess levels in order to protect the system against un-authorized operations.

Hint!For more information about access levels, please refer to the User Guide.

2.2.6 DisablementsIt can be necessary to disable parts of the system for a variety of reasons, e.g.maintenance. It is Possible to disable different devices attached to the system, suchas zones and detectors, either permanently or by using an internal timer.

All disablements will be presented in a disablement list.

Hint!Instructions on how to enter a disablement is described in the User Guide.

2.2.7 Test modeThe system has a test mode function which makes testing easier. When a zone is intest mode external alarm devices and controls will not be activated in case of a gasalarm.

Hint!For more information about test mode, please refer to the User Guide.

2.3 CCP System Modules

2.3.1 Main groups of CCP modulesAll CCP addressable modules must be given an unique technical address in orderto make it possible for the software to identify the modules. Instructions on how toset the address are found on the data sheets for each module.

Hint!The function for every module has to be configured in the Configuration program,please refer to the Configuration Manual.

There are three main groups of CCP modules:

• Control modules.A controller module can act as a Master controller or be set in Managed modecontrolled by a master controller. A controller stores all events in the systemwhether they work as a master controller or they work in managed mode.

• Managed modules.



All addressable modules except the master controller belongs to this group.

• Non-addressable modules.This group includes modules such as the PSU, Isolator M, Surge Prot M andPower Boost M.

Figure 4. Some examples of CCP modules.

2.3.2 Control Modules, information and control/processlevel2.3.2.1 Different types of controllersIn the CCP system there are different types of controllers. There can be a maximumof 10 controllers in a Salwico GDS and the system must always have at least onecontroller with technical address 1.

• Control M Gas has a 4.3 inch display and is able to run in two modes:• As a supervisor with default access level 1, in this mode the Control M Gascannot affect the system unless the user changes the access level.

• As a controller with default access level 2, in this mode the Control M Gascan affect the system via mute reset etc. Some functions are protected byaccess level 3 and 4.

• Control M X has no display and will function as a managed controller withoutHMI.

Figure 5. Control Modules.

2.3.2.2 A Controller in Master modeA master controller is able to and/or responsible for the following:

• Store and distribute the definition file to all controllers.

• Initialize all managed modules with current definitions.

• Monitor all managed modules.

• Controlling communication.



• Control and monitor I/O based on the Cause/Effect.

• Store all events in the system.

• Store history.

• Protocol conversion for optional protocols such as NMEA and Modbus.

• Communication with presentation and monitoring systems.

• Update firmware for all addressable modules with the exception of the controlmodules.

NOTE!The “main control panel”/Master controller in the Salwico GDS shall always haveaddress 1 and has to be a Control M Gas connected to a BusCon M Gas module.

2.3.2.3 A Controller in Managed modeA controller in managed mode can be either be a Control M Gas or an Contol M Xand the allowed address range is 2-10 .

A Managed controller is able to and/or responsible for the following:

• Store the definition file.

• Store all events in the system.

• Protocol conversion for optional protocols such as NMEA and Modbus.

• Communication with presentation and monitoring systems.

• Update firmware for all addressable modules with the exception of the controlmodules.

2.3.3 Managed modules, Field layerAll modules in this layer are connected to Backbone Bus and they have noconnection/knowledge to the other managed modules connected to the bus with theexception of “Basic Backup Signal”.

In principle, all decisions relating to alarm, fault and status of the inputs isdecentralized to this layer. The output is controlled from the control layer byCause/Effect and the definitions. There are one exception for making decisions onwhether an output should be active or not, and it is the Basic Backup signal (xGassignal). See the description in Basic Backup Signal, BBS, page 15.

All Managed modules will be initiated with the current configuration when thesystem starts up and store the configuration.

2.3.4 Address range, ModulesSalwico Gas Detection System (Salwico GDS), unlike Salwico Fire DetectionSystem, has a fixed address range for the various modules as follows:



Address Module Number ofmodules

1 Control M Gas 12-10 Control M Gas / Control M X 911-74 Analogue M 4-20 6475-90 Relay M 8 1691-125 Invalid (Spare) 35



System description & Application examples 3 Single Central System (SCS)


3 Single Central System (SCS)

3.1 GeneralA Single Central System (SCS) is a complete system that can operateautonomously; monitor its detectors and inputs, activate its outputs and display itsfaults and alarms.

Figure 6. An example of a Gas Detection Distributed System

All CCP modules in an SCS system communicates and is powered via a bus calledthe Backbone Bus. Each central can only have one Backbone Bus.

The Backbone Bus is designed for usage in two different environments:

• Backbone Bus Internal (BBI)The main bus inside a Central cabinet used for communication betweenModules. It consists of two redundant RS-485 channels, two 24 VDC powerlines and the Basic Backup Signal (BBS).

• Backbone Bus External (BBE)The main bus outside a Central cabinet used for communication betweenModules and stretched central parts. It consists of two redundant RS-485channels, two 24 VDC power lines and the Basic Backup Signal (BBS).

An important difference of Backbone Bus Internal (BBI) and Backbone BusExternal (BBE) is that BBE is designed to withstand electrical environment outsideof a cabinet and that it isolates the BBE and BBI from each other so that shortcircuits and other errors do not affect the internal bus (BBI).

It is possible to stretch a central. A stretched Central is physically distributed totwo or more physical locations. The stretched centrals must be connected with the

3 Single Central System (SCS) System description & Application examples


Backbone Bus External (BBE) in order to act as if they were in the same cabinet.One location may or may not supply power to another location (segmented) andtwo locations may or may not have isolated communication lines.

In a Single Central System (SCS) there must always be one Master controller.

There are limitations on the number of modules that may be included in a singlecentral system or with other words on the “Backbone Bus”. See Address range,Modules, page 8.

3.2 Safety functionThe safety function in the system is to detect gas alarms via transmitter interfaces(also called 4-20 mA interfaces) and set the alarm LED on the correspondingtransmitter interface on the module it is connected to. The system will also set acommon alarm LED and alarm relay.

The Backbone Bus contains a signal, xGas, which will be activated by any modulethat detects a gas alarm.

Hint!Read section Basic Backup Signal, BBS, page 15 because this signal (alsoknown as xGas) is essential to the "Safety Function”.

When xGas indicates that there is a gas alarm in the system the common alarmLED on the Control M and the alarm LED on the corresponding transmitterinterface lights up and a relay output on BusCon M Gas is activated, this functioncannot be changed or disconnected depending on rules and standards. This functionis controlled by hardware!

The illustration below shows how the safety function works – note that there can beseveral modules of each type.

3.3 Backbone Bus

3.3.1 Backbone Bus communicationThe Backbone Bus Topology used in the CCP system is a centralized networktopology in which a number of CCP modules are attached to a bus called theBackbone Bus. All messages sent on the backbone bus hold a destination address



to the receiving module. Each module is identified by an individual address andwill only receive messages with a proper address. This system is very flexible asnew modules can be added on easily.

Each module has built-in protection to prevent internal faults in the modules toaffect the bus. This together with redundant communication and power supplymakes the system fault tolerant. If a module is damaged, the rest of the system willcontinue without interference.

The protocol used for communication in the CCP system is developed byConsilium and called CSP/CSTP. The messages are sent on two communicationchannels in the Backbone Bus.

Communication parameters for BBI and BBE:

• Baud rate: 38400

• Data bits: 8

• Stop bits: 1

• Parity: non

The Backbone Bus consists of ten conductors; the Basic Backup Signal (BBS), tworedundant RS-485 channels, two 24VDC power lines and one spare conductor.

Table 2. Backbone Bus connections to modules.

BBI 26 RS-485 Communication Channel 2 D-7 24 VDC Power Supply 1 +8 24 VDC Power Supply 1 -9 24 VDC Power Supply 2 +10 24 VDC Power Supply 2 -



3.3.2 Basic Backup Signal, BBSThe Basic Backup Signal, also known as xGas1, is a signal in the Backbone Busthat is used for transmitting the Central's alarm status.

The outputs supporting the Basic Backup Signal have an xGas property that can beset in the Configuration Program.

Modules not having full contact with the controller act upon the Basic BackupSignal.

NOTE!The pre-alarm level does not affect the Basic Backup Signal.

There are some rules for xGas:

• Modules that can act as a Controller are able to generate a 2.0 V SurveillanceVoltage on the Basic Backup Signal. At present only the Control M Gas can actas a Master.

• Only one Module within each Central may generate the 2.0 V SurveillanceVoltage on the Basic Backup Signal.

• All Modules that can generate alarms is able to generate the 6.0-28 V GasVoltage signal on the Basic Backup Signal.

• Modules that can be configured to handle xGas Alarm shall supervise the BasicBackup Signal for faults.

Figure 7. Signal levels Basic Backup Signal

NOTE!When a BBS/xGas signal is transmitted via a Power Boost loop the signal has otherelectrical properties. For more information see section PB-485, page 21.

3.3.3 RS-485 communication, BBIThe main bus communication consists of two redundant RS-485 channels. If thebus is split into more than one segment in a central, the RS-485 bus shall beterminated in both ends with a 120 Ω resistor. See separate description in terms oftermination.

A two-wire connection shall be used if the modules have common ground (-).

It is possible to split the BBI in to separate galvanically isolated segments in acentral, but then the Bus Isolator M must be used between the galvanic segments.In this case, a three-wire connection shall be used for RS-485.

1) A subsystem of xGas is the signal PBxGas used by the Power Boost M module on a Power Boost Loop.



3.3.4 Power supply, BBIThe power supply consists of two redundant 24V DC lines with a maximumcurrent of 8A per channel. Note that the channels are redundant which gives theresult that the maximum current shared, counted on both channels, may not exceed8A.

3.3.5 System communication, overview

Figure 8. System communication block diagram

3.3.6 Backbone Bus Internal (BBI)The main bus inside a Central Cabinet is used for communication betweenModules.

3.3.7 Backbone Bus External (BBE)3.3.7.1 Overview BBEThe main bus outside a Central cabinet used for communication between Modulesand stretched central parts. It consists of two redundant RS-485/PB-485 channels,



and an optional power bus (two 24 VDC power lines or a 48 VDC loop) and theBasic Backup Signal (BBS).

When there are more modules outside the cabinet, i.e. if the central is a stretchedcentral that consists of two or more cabinets, they must be connected to the sameBackbone Bus. This is achieved by connecting a cable from the terminals onmodules Surge Prot M or Bus Isolator M. This cable connection is then called theBackbone Bus External (BBE).

The Bus Isolator M and Surge Prot M have built-in repeater functions and willamplify the signal intensity and makes it possible to increase the length of thebackbone up to 700 meters. Another advantage of the built-in repeater function isthat the BBI and the BBE will be separated so a BBE short-circuit will notinfluence the BBI.

Hint!Read the paragraph that deals with the Power Boost M for cases where the PowerBoost M is used to link together a stretched system.

If the modules outside the central have a separate power supply it is stronglyrecommended to use two Bus Isolator M modules to galvanic isolate the differentsegments in order to prevent interference caused by ground current or othersources.

By mounting additional Bus Isolator M or Surge Prot M modules on the BackboneBus Internal it is possible to get up to 10 Backbone Bus External branches (RS-485segments) with a maximal length of 700m each from one Single Central System(SCS), see Block diagrams for Surge Prot M and Bus Isolator M, page 17.

3.3.7.2 Block diagrams for Surge Prot M and Bus Isolator M

Figure 9. Surge Prot M H module on the BBI.



Figure 10. Two Bus Isolator M H modules on the same BBI.

NOTE!The channel selector inside the Bus Isolator M must be set to 1 in one module andto 2 in the other module.The 0.5A power output is not galvanic isolated.

3.3.7.3 RS-485RS-485 is used for the communication between modules in a stretched system.RS-485 is a worldwide industry standard defining the electrical characteristics ofdrivers and receivers for use in digital multipoint systems. The interface isbalanced and relatively insensitive to interference. There are some generalrecommendations for installation of RS-485:

• Twisted pair wires should be used.

• Shielded cables must be used.

• Star networks in a RS-485 segment are not permitted.

• Termination shall be made at each end of the bus with a 120 Ω resistor toprevent reflections in the cable.

• Max 700m cable in one communication segment.

• Two-wire connection shall be used when nodes have common ground (-).

• Three-wire connection shall be used when nodes have different grounding (-),for example between Bus Isolator M modules.

The connections must be done with the correct polarity, in relation to each other. Apolarity error means that the equipment will interpret the data incorrectly. In theCCP system the signals are marked with D+ and D-.



3.3.7.4 PB-485Due to the large voltage differences which may occur on a power boost loop aspecial RS-485 driver has be chosen for the communication on a Power Boost loop(equal to BBE) and the signal name is PB-485.

Power Boost has two PB-485 channels for transferring BBE communication in astretched system.

Hint!For more information about PB-485 see chapter Power Boost Loop, page 19.

3.3.8 Protocols, overviewThe CCP system support the following protocols for communication with externaldevices:

• MODBUS

• NMEA

Using a serial interface of type RS232 , RS422 or RS485 via one or moreControllers.

Please contact Consilium support for an updated list of supported protocols and theconditions that apply for the different types of protocols.

It is possible to supervise the status for all point detectors via the MODBUSinterface:

• Alarms status (1, 2 or pre, muted yes/no)

• Fault status (yes/no, muted yes/no)

• Disablement status (yes/no)

Hint!For more information about Modbus protocols refer to document “6300705 CCPGas Modbus protocol.doc”.

3.4 Power Boost Loop

3.4.1 Power Boost overviewThe Power Boost Loop is a subsystem in the Salwico GDS.

See the figure below for an overview how the Power Boost Loop works – note thatthere can be several Power Boost Loops in one Salwico GDS.



Figure 11. An example with several Power Boost Loops in one Salwico GDS

3.4.2 Power Boost module, System functionsThe Power Boost M module provides:

• Centralized power supply through a Power Boost Loop that is secured againstinterruption and short circuit.

• Compensation for voltage drop in the cable for distributed modules.

• Transfer of xGas status between the Power Boos modules on a Power BoostLoop (Signal name PBxGas) and the modules connected to the Power Boostmodule on the local Backbone Bus (BBI).

• A DC/DC converter for 48 VDC to 27 VDC supplying power for channel 1 and2 on the local BBI.

• Supervision of Power for channel 1 and 2 on the local BBI.

• External Backbone Bus (BBE) PB-485 communication between modules.



• Protection of the External Backbone Bus (BBE) PB-485 communicationbetween modules against interruptions and short circuits.

• Supervision of the 48 VDC and PBxGas signals.

3.4.3 Power Boost working modesThe Power Boost M module can work in two different modes:

• Master for the power loop in a system with distributed Power Boost M modules.

• Distributed Power Boost M module.

In master mode 48V power shall be connected to the 48V input terminal. Theterminals 48 A and 48 B shall be connected in a loop to the slave modules. Slavemodules have their 48A and 48B connected from the master or a neighbouringslave in a ring-like fashion. Slaves have their 48V input terminals unconnected.Master mode is decided by the DIP numbered as 4. If this is on, then it is a slave.

3.4.4 PB-485Due to the large voltage differences which may occur on a power boost loop aspecial RS-485 driver has be chosen for the communication on a Power Boost loop(equal to BBE) and the signal name is PB-485.

The Power Boost has two PB-485 channels for transferring BBE communication ina stretched system. The two PB-485 channels are transformed to two standardsRS-485 in the Power Boost Module and are used for the local BBI-bus.

Power Boost module has built-in repeater functions and will amplify the signalintensity and make it possible to have 700 meters of cable between modules.

NOTE!It's not the PB-485, that sets limits to how far apart two modules can be placed; it iscurrent consumption and the cable area.

Another advantage of the built-in repeater function is that the BBI and the BBEwill be separated so if a BBE short-circuit it will not influence the BBI.



Figure 12. Principle diagram PB-485/RS-485 in a Power Boost module

NOTE!PB-485 communication is not compatible with the ordinary industry standardRS-485.

General recommendations for installation of PB-485 (same as for RS-485):

• Twisted pair wires should be used.

• Shielded cables must be used.

• Star networks in a PB-485 segment are not permitted.

• Terminations are made on the system boards. No extra resistor is needed for endof the bus termination.

• Max 700m cable between power boost modules.

• Two-wire connection shall be used.

The connections must be done with the correct polarity. A polarity error means thatthe equipment will interpret the data incorrectly. In the CCP system the signals aremarked with D+ and D-.

3.4.5 PBxGas signalThe PBxGas signal transfers xGas status between distributed modules on thePower Loop and are distributed to modules on the BBI.

The software supervises the xGas signal in the backbone. This signal can also beasserted by hardware and relayed between islands by the PBx A and PBx B signals.The software has the responsibility to indicate the state of xGas on the xGas LED.

‘PBx’ printed on module front label (indicators and connections) corresponds tothe PBxGas.

The xGas LED will show the following states:

• Off if the xGas signal is in the interval 1V to 4V. This is the normal state.



• Yellow to indicate fault if the xGas signal is below 1V. This indicates a fault inthe xGas signal.

• Steady red if the xGas signal is in the range 4V to 5.5V. This indicates thatanother island has activated xGas and this PowerBoost has activated the XGassignal in this backbone.

• Flashing red if the xGas signal is above 5.5V. This indicates that a module onthis backbone has activated xGas.

The xGas signal is transferred by hardware in a coded manner with the PBxGassignal where a 10Hz square wave is transferred from the master in order to detectan intact connection.

On slaves, incoming PBxGas signals is routed directly to the outgoing PBxGassignal that then connects to the neighbouring slave or finally the master. ThePBxGas signal is routed directly from input to output by setting DIP3 to theon-state. The hardware detects if there is a difference between the incomingPBxGas signal and the outgoing PBxGas signal with a signal called LOOP_OPEN.For a slave this shall never be active since DIP3 short circuits PBxGas from inputto output. For a master, where DIP3 is off it indicates a break somewhere in theloop between input and output, typically a cable break.

The average voltage of the PBxGas is detected and generates a signal calledLOOP_HIGH via hardware. This signal also goes high when the 10Hz signal ispresent since its average value is above the threshold.

3.4.6 Power Loop 48 VDC Inputs/OutputsIf a Power Boost M module detects a short circuit on a 48 VDC output it willisolate the output automatically, the output is automatically switched on if no shortcircuit on the non-energized side is detected.

3.4.7 TerminalsThe Power Boost M module provides the following interfaces on terminals:

• A 48 VDC (5 A) input for powering of the Power Loop. (To be used if modulein master mode).

• A fault output, dry contact.

• An xGas standard signal for connection within a single cabinet.

• A BBE communications interface, 2 x PB485 outputs.

• Two PBxGas interfaces for transferring and monitoring the xGas signal todistributed Power Boost M modules.

• Two Power loop interfaces.

3.4.8 Power fault relay3.4.8.1 Relay function, Power Boost M in master modePower Boost M module in master mode supervises:



• Two power loop outputs for short circuit and overload.

• A 48 VDC power input.

• Cable breaks on the PBxGas Loop.

When a fault is detected, the fault relay is put into fault state.

NOTE!The fault output is active low, i.e. closed when there is no fault.

3.4.8.2 Relay function, Power Boost M in distributed modeA Power Boost M module in distributed mode supervises:

• Power loop input/output’s for short circuit.

• Power loop input/output’s for cable break.(When the voltage is zero on a power loop input/output that’s not shortcircuited.)

• Power loop input/output’s voltage.

When a fault is detected, the fault relay is put into fault state and the BBI powerChannel 2 will be deactivated if BBI power on channel 1 is OK.

NOTE!The power on channel 2 is shut down to force the modules associated with the BBIto generate a voltage fault because the Power Boost module cannot communicatewith the Control M Gas.

NOTE!The fault output is active low, i.e. closed when there is no fault.

3.5 Input/Output Interfaces

3.5.1 GeneralThe I/O types are defined in the CCP system and each module has a combinationof these I/O’s. This document is only treating the relay output.

Each input that can generate an alarm shall be associated with a Zone. The zonenumber shall be configured via the Configuration Program.

Normally the outputs are controlled from the Cause/Effect and definitions, butthere are exceptions whether an output should be active or not and it is the BasicBackup Signal. See description in Basic Backup Signal, BBS, page 15.

The system includes a number of predefined groups for outputs. When the systemis defined, it is possible to associate an output to one of the groups and gives it afeature that makes it possible to disconnect the output from the Control Panelexcept for the Firm Output Group.

Predefined Output Groups:



• General output:The I/O is used as a digital output and can be programmed from theCause/Effect.

The system includes a number of predefined groups for Inputs. When the system isdefined, it is possible to associate an input to one of the groups.

Predefined Input Groups:

• General Input:The I/O is used as a digital input and can be programmed from theCause/Effect.

• Fault input:The loop is used as a digital input. A fault appears when the input is Activated.

4 CCP Modules Descriptions

NOTE!The system description includes all the modules that are designed for the CCPPlatform regardless of which certificates are available for the different modules.Check with marketing or product manager which markets the specific modules areapproved for.

4.1 Control modules

4.1.1 OverviewIn the CCP system there are two modules that can act as Control modules. Thecontrol modules have the same control possibilities, but different HMI functions.

All Control modules can be set in Controller mode as a Master controller or be setin Managed mode controlled by a master controller.

There are some simple addressing rules for Control modules:

1. Master Controller address 1

2. Controller in Managed mode address 2-10

4.1.2 Control M Gas Internal / Control M Gas External

Figure 13. Control M Gas Internal

The Control M Gas is a Control Panel with a 4.3" graphical colour display used toindicate system status. It communicates with other modules on the redundantsystem bus. It can also be connected to other systems via high-speed interfacessuch as Ethernet 10/100 Mb/s, RS-485 or digital I/O. It can act either as a MasterController, or as a Managed module depending on the setting of DIP-switches.

4 CCP Modules Descriptions System description & Application examples


NOTE!A Control M Gas with address 1 (Master Controller) must always be connected toa BusCon M Gas. The BusCon M Gas module has a 20-pin flat cable connector forthe connection.

The Control M Gas is equipped with an USB host for USB flash drive to load orsave a configuration file and update firmware. In the Configuration program theControl M Gas can be set to any address between 1 and 10. The default value willbe 1 if it is the first module of this type to be added, otherwise it will get a highernumber as default.

4.1.3 Control M X

The Control M X is used to convert protocols such as Modbus/NMEA.

A Control M X cannot be used as a Master Controller.

This module provides:

• two programmable Relay contacts

• a USB Host

• one Ethernet 10/100 Mbit (RJ-45), autosense

• a Backbone Bus Interface

• one isolated RS-422/RS-485 interface

• one isolated RS-232 interface

NOTE!The software in a Control M X cannot be updated centralized. Each Control M Xmust therefore be updated via a Ethernet with a special software. Please see theservice documentation for more details!

In the Configuration program the Control M X can be set to any address between 2and 10. The default value will be 2 if it is the first module of this type to be added,otherwise it will get a higher number as default.



4.2 Connection interface modules

4.2.1 BusCon M Gas

The BusCon M Gas contains no software and includes protected power inputs forthe system, monitors supply voltage and provides backbone extension for theControl M Gas. It is equipped with a 20-pin flat cable connector for connectionwith a Control M Gas.

The BusCon M Gas has 2 inputs on terminals:

• Primary Power Supply 19-30 VDC channel 1, supplies Backbone Bus andControl M Gas, automatic fuse (8A).

• Secondary Power Supply 19-30 VDC channel 2, supplies Backbone Bus andControl M Gas, automatic fuse (8A).

NOTE!Supervised by the Control M Gas via the 20-pin flat cable connector.

The BusCon M Gas has 5 dry relay contacts on terminals:

• Gas alarm level 1, common, active high

• Multi-purpose output

• Fault, common, active low



NOTE!Set by Control M Gas via the SPI bus in the 20-pin flat cable connector.

The BusCon M Gas is also able to monitor the xGas signal.



4.2.2 Surge Prot M

The Surge Prot M has three major functions:

• Surge protected power inputs for the Backbone Bus Internal, BBI.

• Terminal board for the Backbone Bus External, BBE (two RS-485 Repeatersare built-in).

• Electronic short circuit protected power outputs for Control or Repeater panels.Note! This output is not supervised.

These functions can be used together or individually.

The module is designed to be used where there are no requirements for electricalisolation between devices. The module has built-in terminators for BBI and BBE.

The unit has no address in the system.

Figure 16. Block diagram for Surge Prot M.



4.2.3 Bus Isolator M

The Bus Isolator M divides the system backbone bus into segments. Its dualfunctionality isolates communications and basic backup signals between thestretched system parts and provides power to the control panel.

NOTE!Each Bus Isolator M has a built-in electrically isolating repeater for one RS-485channel and for the xGas signal (BBS).

Bus Isolator M is strongly recommended when extracting the system backbone bususing separate power sources for the different segments in order to preventinterference caused by ground currents or others sources.

The Bus Isolator M has only one communications channel, so two modules areneeded to create one BBE-bus. Select the appropriate channel with the channelselector.

CAUTION!Only one of xGas signals may be connected when two Isolators work in pairs.

NOTE!BBS and the RS-485 channels on a single module has a common signal ground, soonly one wire for signal ground needs to be installed between the modules.

The unit has no address in the system.



Figure 17. Block diagram for two Bus Isolator M modules on the same BBI.

NOTE!The channel selector inside the Bus Isolator M must be set to 1 in one module andto 2 in the other module.The 0.5A power output is not galvanic isolated.

4.2.4 Analogue M 4-20

The Analogue M 4-20 provides four transmitter interface (4-20 mA inputs).

In order to avoid a massive start-up current in the system induced by the start-upcurrent of the individual gas detectors connected via the 4-20 mA interfaces, thevoltage output (+, SG) in the transmitter interfaces is delayed upon start-up of theAnalogue M 4-20 module according to the following:

• Transmitter interface 1, 0 ± 10 ms






Furthermore the voltage output is delayed based on the DIP address:

• DIP 31, 500 ms

• DIP 32, 1000 ms

• DIP 33, 1500 ms

• etc.

NOTE!Analogue M 4-20 with DIP addresses below 31 will NOT be delayed with respectto DIP Address.

In the Configuration program the Analogue M 4-20 can be set to any addressbetween 11 and 74. The default value will be 11 if it is the first module of this typeto be added, otherwise it will get a higher number as default.

4.3 Power supply modules

4.3.1 PSU M AC/DC 5A

The PSU M AC/DC 5A powers the system. It is short-circuit proof and can be usedin pairs to supply 5+5 A.

This unit has no address in the system.

It is possible to connect two PSUs in series to power “Power Boost loop” with 48VDC.

The voltage output from the PSU to be set at 24 VDC, whether they are connectedin series or parallel.



4.3.2 Power Boost M

The Power Boost M (PBM) is a module without system software and its purpose isto supply:

• Centralized power supply through a Power Boost Loop that is secured againstinterruption and short circuit.

• Compensation for voltage drop in the cable for distributed modules in gas alarmsystems.

• Transfer of xGas status between the Power Boost modules on a Power BoostLoop (Signal name PBxGas) and the modules connected to the Power Boostmodule on the Internal Backbone Bus (BBI).

• External Backbone Bus (BBE) PB-485 communication between modules.

• Protection of the External Backbone Bus (BBE) PB-485 communicationbetween modules against interruptions and short circuits.

• Supervise the 48 VDC and the PBxGas signals.

4.4 Input/Output modules

4.4.1 Relay M 8



The main purpose of the Relay M 8 is to control gas alarm, fault alarm andcontroller relays.

A Relay M 8 provides:

• Eight programmable relay contacts.Each of these relay contacts provide a potential free change-over contact.

It is possible to give the outputs the following properties:

• Active High or Active Low.

• Enable/disable xGas.

In the Configuration program the Relay M 8 can be set to any address between 75and 90. The default value will be 75 if it is the first module of this type to be added,otherwise it will get a higher number as default.



System description & Application examples 5 Configuration program


5 Configuration program

5.1 OverviewBefore the system can be used, it must be both physically and functionallyconfigured. The configuration program is especially designed for creating a systemconfiguration file for a system. The configuration program is designed to run on acomputer that can support Microsoft Windows NT, XP, 2000, Vista or Windows 7.

Hint!For more information about the configuration program, see the separateConfiguration Manual.

Once the configuration file is created it must be downloaded to the control panel inthe system. This is done by using an approved USB memory stick. Theconfiguration file must have the file extension “.ccp”. It is possible to download thecurrent configuration file from the system to the computer, modify the file andupload it again to the control panel in the system.

When the system is started, the master controller initiates all modules in the systemwith the specific data from the configuration file.

5.2 Description

Figure 18. The Start window when opening a new configuration.

5 Configuration program System description & Application examples


The configuration program is divided into four functionally and well-defined mainapplication windows; System, Users, Zones and Central module tree. Thesewindows are used to define the Salwico GDS both physically and functionally.After the configuration has been performed, theMain menu is used to manage aconfiguration file, to load a file into the program, and to save a configuration fileupdate.

The modules are defined, one at a time, by entering different settings.

The System window includes information about the current configuration file andtext fields in which the name and reference of the project is entered. Give theinstallation a specific name to make it easier to document each installation.

The Users window is used to handle new and existing users of the gas detectionsystem.

In the Zones window, there is a list of all zones defined in the system. It is possibleto name the zones.

In the Central window, the centrals are defined physically and functionally.Modules and Salwico Language programs are added and defined in the central.

The physical configuration handles the definition of centrals, serial communicationports, zones, detectors, and supplementary texts.

The functional configuration defines how the inputs and outputs of the systemshould react. The commands are written in the Salwico language.

Hint!For more information about the configuration program, please refer to the GasConfiguration Manual.

5.3 The Salwico languageAn essential part of configuring a system for control and supervision is to specifyits reaction for certain events, for example what will happen if a sensor is activated.To simplify the configuration of the system, Consilium has developed the Salwicolanguage. It consists of a set of commands and a well-defined syntax. Thecommands are entered in Cause/Effect sheets located under the 'SalwicoLanguage' branch in the module tree window.

Hint!The Salwico language is described in detail in the Configuration Manual.
