1 System Description

1.1 General

The E-CO2 release system is designed for control of fixed gas fire-extinguishing systems as defined in the FSS-Code Chapter 5 by the Convention for the Safety of Life at Sea (SOLAS). Typical applications are control of fixed gas fire-extinguishing systems for engine rooms and cargo holds. Its main features are:

● high availability by permanent self-supervision of the control system ● easy and intuitive operation due to clear arranged layout of the release panel ● status information at the release panel by LEDs and a large clear text display ● max. 32 sections with max. 8 cylinder groups can be controlled

● max. 6 sections can be controlled from one release panel ● automatic generation of pre alarm signal

● flexible configuration of the release modus (one or more shots per section, number of cylinder groups) ● several release panels can be connected to one release system

● effective protection against false release integrated ● easy installation

● no pilot cylinders and pilot pipes required

● manual override function for the section valves and the cylinder group valves

● interconnection between the release panel(s) and the module cabinet by means of a 4-wire CAN-bus

1.2 Main System Components and Locations

1.3 General Function Description

1.3.1 Normal Operation (Stand by)

During “Normal Operation” the system permanently monitors the power supply sources and the circuits to the valve actuators as well as the interconnections between the release panel(s) and the module cabinet. In case of a fault condition a warning signal sounds at the release panel(s) and the reason for the fault condition will be shown on the display of the release panel(s). A signal will be given to the ship's supervision system by means of a relay contact.

1.3.2 Release Procedure

The E-CO2 system can include one or more release panels CP-30. Each release panel allows release of max. 6 sections. If more than 6 sections shall be controlled from one location, several release panels can be mounted in parallel. Furthermore, depending from the system configuration, one section can be released from different release panels at different locations. It is also possible, to start a release procedure at one release panel and continue the release procedure at another release panel.

The system release will be carried out in 2 steps:

1. Press button (1) to open the section valve(s) indicated on the adjacent label. 2. Press button (2) to release the related cylinder groups.

A signal for activation of audible pre alarm will be generated automatically (see section 3.3 “Pre Alarm”). An internal time delay ensures, that the cylinder groups cannot be released before the configured time delay has elapsed.

Depending from the system configuration, it is possible to release several cylinder group combinations (shots) by repeated operation of button (2). Max. 4 shots per section are possible.

For a detailed description of a typical release procedure read “Typical Release Sequence” in section 4.5.

1.3.3 Emergency Release

In case of emergency the section valves and the valves of the first cylinder of each cylinder group can be operated manually. Manual operation of the valve of the first cylinder in a group opens consequently all other cylinders of this cylinder group.

1.3.4 Safety Shut Down

If the system detects a severe fault (i.e. an unintended activation signal to a cylinder group valve during normal operation), the safety shut down function disables the systems and thus prevents a false release of the system. The system remains in the disabled state even after switch off. Return to normal mode requires a manual operation after elimination of the reason for safety shut down.

For a detailed description of the safety shut down function read section 2.2.3 “Safety Module and Safety Shut Down” and chapter 9 “Activation, Reset and Test of Safety Shut Down”.

2 Safety of Operation

2 Safety of Operation

2.1 System Availability

Through comprehensive self supervision of the Alarm and Control System ACS, faults occurring in this system will be recognized in an early stage. The appropriate fault state will be indicated on the release panel(s) and a fault signal will be transferred to the ship's automation system. The self supervision comprises the following functions:

● monitoring of power supply sources

● monitoring of circuits to section valve actuators and cylinder group valves ● monitoring of all modules connected to the CAN-bus

● monitoring the correct function of the extinguishing system during release procedure

Early warnings at the release panel(s) and at the ship's control system allow an early action and a high availability.

2.2 Protection against False Release

It is of particular importance for a gas fire-extinguishing system, that no false releases can take place, even if a fault in the control system occurs. The following potential risks are identified, which could theoretically cause a false release of the extinguishing system:

2.2.1 Corruption of a CAN-Bus Message

The CAN-Bus system has been developed as a bus system, that is able to recognize corrupted bus messages extremely reliable by means of several different corruption detection mechanisms. Once a corrupted message is detected, the message will be rejected by the CAN-bus hardware of all bus listeners to avoid any (false-) interpretation.

If however a randomly corrupted message would occur, the likelihood of being further processed is small, because most randomly altered messages will not be accepted by the software. From the remaining ones again only a small part is able to open a section valve or a cylinder group valve. These system states will be handled by the safety module, which is able to trap software and hardware faults by “hardwired” detection functions (see below). In case of fault the safety module proceeds a “Safety Shutdown”. A false release will not take place.

2.2.2 Damage of one or more Micro Controller Outputs

A damaged micro controller output can be permanently activated or permanently deactivated. A permanently deactivated output will not impose a direct threat. It is a matter of regularly function tests to verify and to rectify the failure.

A erroneously activated output will be detected by the safety module (see below), which then proceeds a “Safety Shutdown”.

A false release will not take place.

2.2.3 Safety Module and Safety Shut Down

For increased safety, the safety module includes additional contacts for protection against false release. Thus three conditions must be given to release a cylinder group:

• the appropriate contact on the I/O-module must be closed

(10)

standby-operation)

• the relay contact “safety shut down” must be closed (closed unless a “safety shut down” condition is

detected).

In case of a severe failure, a “hardwired” fault detection facility interrupts the circuits to the section valve actuators and to the cylinder group actuators (“safety shut down” function).

Error Signals to Cylinder Group Actuators

During normal operation the safety module interrupts the circuits to the cylinder group actuators until a section valve has been opened and button (2) of the release panel has been pressed. A successful activation of a cylinder group solenoid requires three pre-conditions:

1. the “release control” output must be activated by pressing button (2) after a section valve has been completely opened.

2. no section valve actuator is active

3. the system is not in “safety shut down” mode.

If the safety module detects an (unintended) activation signal for a cylinder group at its inputs, while the release control signal is not active or while a section valve actuator is active, the safety module will proceed a “safety shutdown” without assistance of the software (“hardwired” function). The cylinder group valve(s) cannot be activated, because these circuits are still interrupted, as long as the release control output is not active. The safety shutdown interrupts the circuits to the cylinder group valves with a further contact. The release panel now issues a fault signal. The shutdown state can only be reset by manual operation (see below).

Error Signals to Section Valve Actuators

If by any fault condition a signal for section valve actuators is present at the input of the safety module, although a button for section valve operation has not been pressed before, the safety module will proceed a “safety shut-down” with software interaction. The safety shutdown will now block the cylinder group actuators permanently. The activation of the release control output will cause the section valves to remain in closed position. Even if the software interaction would fail, the safety module blocks the cylinder group actuators as long as at least one section valve actuator is powered. Thus a release of the extinguishing system by error signals is not possible. Reset of Safety Shut Down State

Once the safety module has tripped to the “Safety Shut Down” state, it can only be reset by manual operation in two steps:

● Allow “Safety Shut Down” reset at the control panel CP-30 ● Press the “Reset” button on the safety module.

3 System Layout

3 System Layout

3.1 General

In a basic system layout the E-CO2 system comprises a release panel CP-30 at the mandatory release location and a module cabinet in the vicinity of the electrical operated valves (section valves and cylinder group valves), and the electrical operated valves themselves. The electric operated valves are the interface to the extinguishing system, but the extinguishing system itself is not part of the E-CO2 system.

According the project requirements it could be necessary to include more than one release panel and more than one module cabinet.

3.2 Power Supply

The Electrical CO2 Release System E-CO2 requires two independent power supply sources. In a basic design

these sources should be main power supply from the main switchboard and emergency power supply from the emergency switchboard.

If the ship's power supply is not backed up by an UPS (Uninterrupted Power Supply) and one of the protected sections includes the three-phase main generator (normally the engine room), the E-CO2 system must be equipped with an internal backup battery and automatic charging device. Power Supply Components:

The nominal power consumption of the system is 150W (without consideration of additional alarm devices).

3.3 Pre Alarm

For CO2 systems, an automatically activated audible pre-discharge alarm (pre alarm) must be provided for RoRo

spaces and other spaces in which personnel normally work or to which they have access. The E-CO2 system generates pre alarm signals by the following operations:

(12)

• pressing button (1) in the release panel CP-30 for opening the section valve(s) and

• manual or automatic operation of the section valve(s) (after leaving the closed position and after reaching

the completely open position).

The pre alarm can be connected at the following positions:

• limit switch mounted directly to the section valve. • I/O-module in module cabinet

• release panel CP-30

For redundancy reasons each pre alarm shall be switched by two contacts. One of the contacts shall be an external limit switch at the section valve, which is open only in the closed position of the section valve, or an output of the I/O-module, where the section valve is connected to. A second contact can be configured at one of the other positions listed above.

3.4 Interface to Ship's Supervision System

As a standard, the release panel CP-30 offers 2 pairs of voltage free switch over contacts, one pair of contacts for a common fault signal and one pair for a common pre alarm (see cable diagram of project documentation). For a permanent supervision of the E-CO2 system it is essential to connect these signals to the ship's supervision system.

Additionally, each control panel includes 6 “open collector” outputs for relay connection, which can be

configured individually for different signal outputs. For example they can be used to switch pre alarm devices in the protected spaces or to output other signals, which shall be connected to the ship's supervision system.

Furthermore, the I/O-modules in the module cabinet can be configured to generate required signals for the ship's supervision system.

3.5 Application of E-CO2 System together with Cargo Hold Smoke Detection

System SDS-48

The E-CO2 system can be applied for cargo spaces, which are monitored by cargo hold smoke derection systems. In this case the section valve actuators (see later in this manual) are connected to the three-way-valves, which switch the pipe to the cargo space from smoke detection system to CO2 extinguishing system. See also diagram

“acs-e-co2.tcd” in the appendix of this manual.

3.6 More than one Section Valve for one Extinguishing Section

It is possible to connect more than one section valve for one extinguishing section. This might be required for large cargo spaces, where additionally a smoke suction system is connected. The system configuration determines, if more than one section valve can be operated simultaneously, or if the section valves for a section will be operated one after the other. If more than one section valve shall be operated simultaneously, the power supply of the system must be designed accordingly.

3.7 Pressure Monitor for Manifold

An optional pressure switch mounted in the manifold can be connected to the E-CO2 system. While in standby mode, the pressure switch will give an early warning in case of any leakage in the cylinders. Furthermore the pressure switch generates a warning, if after release of a cylinder group no pressure in the manifold will be detected.

Reset tool 023000064

The cylinder group pilot valve is compound of a valve body, the electromagnetic actuator and the manual tripping mechanism. The valve has an pilot output for pneumatic control of further cylinders. Supply voltage for the electric actuator is 24V +/- 15% and current consumption is 0,5A +/-10%.

Important Notice:

For an electric release test, the electromagnetic actuator must be dismantled from the valve. If the release of the electromagnetic actuator was successful, the release pin in the actuator shows a red mark. For reset of the electromagnetic actuator the reset tool must be used. After success-ful reset, the red mark of the release pin has disappeared.

Do not activate the electromagnetic actuator while being mounted on the valve. When the actuator would be dismantled for reset, the cylinder valve could possibly not close completely!

7 Cabling

7 Cabling

7.1 Cable Types

International Regulations:

● IEC-Publication 60332-3 (fire retardant cables) ● IEC-Publication 60331 (fire resistant cables)

Typical Cable Types (comparable cable types of other manufacturers are possible):

Cable Connection Cable Type *)

Mains Power Supply (230 or 110 V AC) MPRX 3G x 1,5

CAN-Bus FMKHC-F 2 x 2 x 0,75

Section Valve Actuator FMKHC 2 x 2 x 0,75

Cylinder Group Actuator FMKHC 1 x 2 x 0,75

Pressure Switch, other Input Channels FMKHC 1 x 2 x 0,75 voltage-free relay contacts for fire alarm, general alarm

system, discharge and fault

specification according to requirements of the monitoring system

*) Observe for possibly differing regulations from the appropriate authorities!

When cables pass through high fire risk areas, main vertical or horizontal fire zones other than those which they serve, they have to be of a fire resistant type complying with IEC 60331.

Important Notice

Cables and wiring serving essential or emergency power or signals should be so far as practical be routed clear of galleys, laundries, machinery spaces of category A and their casings and other high fire risk areas. All electrical cables and wiring shall be at least of a flame-retardant type or of a fire-resistant type for areas defined above and shall be so installed as not to impair their original flame-retardant properties. Values of cable types indicated above are minimum requirements. However the cable types must be in accordance with the authorities having jurisdiction, such as flag state and classification society rules and regulations.

7.2 Cable Shields

The cable shields must be connected to ground as shown in the project's cable diagrams. To provide a good shielding against interfering radiation, cable shields must be connected to ground on both ends. In the module cabinet and in the release panel the cable glands must be used for cable shield ground connection. In the section valve actuator the cable shield must be connected to the metal valve body with a special clamp, which allows a large contact area.

7.3 Maximum Resistance of Input Circuits

(30)

7.4 Maximum Length of Cables to Section Valve and Cylinder Group Actuators

The actuators recommended in this manual require a supply voltage 24V DC with max. tolerances of +/- 15%. Due to voltage drop in the cable, the maximum acceptable cable length must not be exceeded to ensure a proper function of the actuator. The calculation below shows, that a cable length of max. 42m is possible to the valve actuator with the highest current consumption. However for practical reasons we recommend to install the module cabinet and the valve actuators as near as possible. For a CO2 extinguishing system normally the recommended

location for the module cabinet is the CO2 room.

7.4.1 Calculation

The following coefficients determine the maximum acceptable cable length:

• cross section of wires

• maximum acceptable tolerance of actuator voltage • current consumption of the actuator

• available voltage at the I/O-module

The maximum acceptable cable length can be calculated with following equation:

Maximum acceptable cable length

l = (ΔU/2I) * γ * A

l cable length in m

ΔU acceptable voltage drop in the cable

I current consumption of the actuator

A cross section of wires in mm²

γ conductance in m/(Ω * mm²)

conductance of copper 56 m/(Ω * mm²)

For the recommended actuators, the max. allowable cable length for cables with 0,75mm² cross section can be calculated as follows:

8 CAN-Bus

8 CAN-Bus

8.1 CAN-Bus Wiring

The CAN-bus is a 4-wire connection, 2 wires serve for power supply 24V to the modules and 2 wires are for the bus with the signals „CAN-H“ and „CAN-L“. The terminal numbers for connection of the CAN-bus-cable are the same as in the whole system:

Terminal No. Signal

11 +24V DC

21 0V

12 CAN-H

22 CAN-L

All CAN-modules should be connected by the CAN-bus-cable in a linear topology. CAN-bus-cable-taps should be avoided.

8.2 Termination Resistors for CAN-Bus

For a correct function of the CAN-bus, termination resistors 120Ω must be connected to both ends of the CAN-bus. Normally a 0,6W resistor is sufficient. However we recommend to use 5W types to avoid damage of the termination resistors in case of accidental connection of the resistors to the 24V line during commissioning.

For later applications with redundant CAN-bus, the release panel implements a CAN-bus repeater, which divides the CAN-bus into different segments. Each segment has to be equipped separately with termination resistors. For ease of application, the termination resistors at the release panel are already integrated in the related adapter ADP-130. For details please refer to the cable diagram of the appropriate project documentation.

8.3 Module Addresses

Each module connected to the CAN-Bus has its unique address for identification. The main control panel has always address „1“. Further modules have subsequent address numbers. The address number will be assigned by means of a „DiP“- switch on I/O-modules, or by means of a menu on control panels with LCD-display.

8.4 CAN-Bus Monitor

All modules (except main control panel ACS01.100) are equipped with a red LED showing the state of the CAN-bus connection:

9 Activation, Reset and Test of “Safety Shut Down”

9 Activation, Reset and Test of “Safety Shut Down”

9.1 General

To protect the extinguishing system against false release in case of a severe system fault, the safety module in the module cabinet interrupts the circuits to the cylinder group actuators and keeps the section valves in a closed position.

9.2 Activation of “Safety Shut Down” Mode

The following fault conditions lead to a safety shut down:

● erroneous voltage higher than 2,50V at the section valve actuators ● erroneous voltage higher than 2,50V at the cylinder group actuators ● erroneous voltage higher than 2,50V at the “release control” signal.

The safety shut down mode will be indicated on the release panel CP-30. On the safety module in the module cabinet the green LED “Ready” is switched off and the red LED “Safety Shut Down” is lit.

9.3 Investigation of the Activation Cause

After the safety shut down mode has been activated, it is important to investigate the cause of the activation. However, before the investigation begins, the extinguishing system must be secured against accidental release. The result of the investigation shall be noticed in the log book.

9.3.1 Circuit Interruptions

For the outputs to the section valve actuators and the cylinder group actuators, the reason for a increased voltage at the outputs of the safety module can be an interruption of the circuits to the actuators. In these cases the afflicted circuit must be re-established and after that the below described reset procedure must be carried out. Normally a disturbed circuit can easily be identified by a flashing circuit indicator for the appropriate channel on the I/O-module (yellow LED). But please note, that in case of safety shut down, all circuits leading to the section valve and cylinder group actuators are interrupted. Consequently all circuit indicators of the circuits to the cylinder group actuators are flashing and they cannot be used to identify a disturbed circuit of a cylinder group actuator, which has initially released the safety shut down. In this case the circuits to the cylinder group actuators must be examined with other means for circuit integrity, for example with a multimeter.

9.3.2 Other Causes

If the above mentioned circuits faults are not the reason for the safety shut down, the channel output voltages of the related channels on the I/O-modules must be checked. Under normal standby conditions, the voltage must be in the range between 0,05V and 2,40V, depending from the connected load. An output voltages higher than 2,50V identifies a disturbed output channel. If the reason for the erroneous signal voltage cannot be clearly identified and removed, the appropriate I/O-module must be exchanged.

(34)

9.4 Reset of “Safety Shut Down” Mode

If during the reset procedure the initial cause for the safety shut down is still present, the safety module should be able to enter the safety shut down mode again immediately after reset. However we strongly recommend to secure the extinguishing system against accidental release, before the reset procedure will be carried out.

Please proceed as follows to return from safety shut down mode:

● Remove the cause for the activation of the safety shut down mode. ● Ensure, that the extinguishing system is secured against accidental release. ● At the release panel CP-30, proceed the following steps:

- Press the SILENCE button longer than 6 seconds to enter the menu function - Press soft key “MORE...”

- Press soft key “RESET SSD”

- Press soft key “YES” to allow the reset of the safety shut down mode

● At the module cabinet, press the reset button on the safety module.

This procedure will reset the complete system. If the cause for the safety shut down is still present, the safety shut down will be released again. If however the system returns to normal operation, ensure, that the extinguishing system will be ready for remote operation.

9.5 Test of “Safety Shut Down” Mode

The safety module includes a test button for a simple function test of the safety module. Pressing the test button activates the safety shut down mode. To return to normal operation, proceed a reset of the safety shut down mode as described above. The test can be carried out at any time, but shall be carried at least out once a year during the annual system check.
