2. The equipment specified in this manual is only to be installed by the Manufacturer’s trained personnel, or by competent persons trained in accordance with the Manufacturer’s installation instructions.

3. Installation must be in accordance with the recognized standards of the appropriate authority in the country concerned. Refer to local, national and company regulations.

4. To protect against cyber threats, installation on a computer network must be carried out in collaboration with your Company’s IT department or professional IT consultants, and the guidelines and recommendations in the Honeywell Network Security Guide should be followed.

5. Do not operate the Touchpoint Pro system or its components outside of their rated operating specification.

6. Touchpoint Pro must not be operated in Oxygen enriched atmospheres, i.e. greater than 25% v/v Oxygen.

7. All equipment containing a User Interface must be suitably protected from direct sunlight and rain.

8. Power Supply Fluctuations are not to exceed DC 18 – 32 V SELV Supply or ±10 % of nominal.

9. All versions of Enclosure are electrical Class 1, and must be connected to Protective Earth (Ground).

10. The Touchpoint Pro installation must include a means of isolating or disconnecting the input voltage supply. The isolation or disconnection device must be conveniently located close to the system and be clearly labelled. For an AC mains voltage supply, the isolation or disconnection device must disconnect both the line and neutral poles, but maintain earth (ground) continuity.

11. The Touchpoint Pro input voltage supply must include over-current protection.

12. All cabling must be appropriately rated and approved in accordance with local, national and company regulations, and suitable for the installation. Additionally, cabling must satisfy requirements defined in the manuals of connected field devices, in particular if the field device is certified for use in a hazardous location.

13. All signal cables and interconnections must be shielded and the shields terminated only at the unified earth (ground) bus bar situated inside the enclosure.

14. All conduits and cable armour shall be bonded to protective earth (ground). To avoid ground loops, isolating cable entry glands shall be used at the enclosure end where conduits or armour are earthed at the sensor end.

15. Cable entry glands, blanking plugs, reducers, adaptors and breather devices must be suitably approved and must not reduce the IP rating or protection levels. Items should not be used if there is a high risk of mechanical damage to the equipment or enclosure.

16. Cable gland plates or blanking plates must be installed using the supplied gaskets and metal fixings. Failing to do so will invalidate the IP rating.

17. Access doors and entry points must not be opened when a flammable gas atmosphere is present (Class 1 Div.2, Class 1 Zone 2, and Zone 2 [ATEX]).

18. Access doors and entry points must be kept closed when the system is energised in normal operation.

19. All equipment in this manual is rated to +2000 m (6562 ft.) altitude maximum.

20. Touchpoint Pro systems may contain hazardous live terminals. Appropriate precautions should be taken during operation, installation, and maintenance and servicing. Specifically, operators must have appropriate training and experience to be aware of the hazards to which they may be exposed, and of measures to minimise risk to themselves or other people.

21. The protection provided by the equipment may be impaired if the equipment is used in a manner not specified or authorised by the manufacturer. This includes being connected to an insecure TCP/IP network.

22. Be aware that extended exposure of a sensor element to certain concentrations of combustible or toxic gases in air can introduce stress to the element that may seriously affect its performance, and therefore recalibration should be carried out or the sensor replaced, or both, after an alarm due to an indication of a high concentration.

23. Risk Assessments should be carried out and alternative safety arrangements should be put in place BEFORE beginning any servicing or maintenance.

3 Touchpoint Pro Introduction

Touchpoint Pro (TPPR) is a Command and Control System designed for the Honeywell Analytics’ (and third party) range of

fixed sensors and detectors. It provides constant sensor monitoring with automatic alarm response and notification. Its alarm levels and responses are fully customisable and all events and errors are logged on a removable SD card for easy archiving.

TPPR is certified to monitor hazardous areas such as Zone 2 Div. 2 via remote Z2D2 enclosures. TPPR can be used indoors or outdoors, in pollution degrees 2 to 4, and up to IP66, depending on the enclosure that is used. In addition it can be securely networked and either controlled or monitored via a secure network connection and the

Honeywell PC Configuration software or via the secure Honeywell Webserver browser interface. Note: Both access methods are optional licensed extras. Please visit the Honeywell website for further information or to

download the Operating Instructions.

3.1 TPPR Access Levels

The table below details the access levels for the Local User Interface (UI). Broadly speaking, an Administrator can commission modules and configure channels, an Engineer can edit channel configuration and do calibrations and testing, and an Operator can acknowledge and reset events during normal day-to-day operation. Other users can view current and historical events and trend data, and generate reports.

TPPR is supplied with a default Administrator level account. For security reasons this password will be attached to the system Touchscreen. When the system is configured, at least one new Administrator account should be created. The default Administrator should then log out and then log back in as the new Administrator, and should then delete the default Administrator account to prevent unauthorized access. The Administrator can create other users with

Administrator level access or lower and the Maintenance Engineer can create users with Engineer level access or lower. Note: Forgotten or deleted passwords cannot be recovered so it is advisable to keep a copy of the master password in a

secure place or have two Administrator accounts. Authorised users can carry out the following tasks:

Key: Yes , No  Read only  Engineer and Operator 

Note: Only Administrators can end another user’s active session. Note: For security reasons some of these tasks are unavailable through PC Configuration and Webserver software. Refer to

the appropriate User Manual for more information.

Note: TPPR’s ability to Accept and Reset events can be restricted to authorised users by changing the software settings.

However, remote switches cannot be restricted through software so alternative switch protection methods should be used where required.

Max. Loop 3 km

<1 km

WARNING

appropriate barriers and armoured conduits, and that you follow all national and international cabling regulations.

3.2.1 Centralised Command and Control Option

TPPR can be installed as part of a centralised cabling system. With a centralised system, the field devices are individually cabled back to the Controller and the field devices’ distance from the controller is limited only by the cable resistance and whether or not power boosters are used.

3.2.2 Distributed Command and Control (Remote Units) Option

TPPR can be installed as part of a distributed cabling system. In a distributed architecture, the field devices are connected via short cable runs to TPPR Remote units, which are connected back to the controller by the Ring Network.

Remote units can be located up to 1 km (cable length) from the TPPR Controller or from each other, with a maximum cable loop of 3 km for the complete system. The only connection required between the Controller and the Remote units is the shielded network cable itself.

The TPPR Remote unit can be housed in any of the standard Enclosures, a 19” 5U rack, or a suitable 3rd-party enclosure. They do not need a Controller but they do require their own power supplies.

Note: Standard Remote Units can be sited in safe areas to monitor and control devices sited in hazardous areas. You

should comply with all relevant legislation and you should follow the field device manufacturer’s installation and use

instructions.

The diagram below shows an example of a typical distributed setup showing both safe zone and zone 2 remote units.

You can install a Zone 2 Remote unit in Zone 2 to monitor sensors in ATEX Zone 1 provided that you use

INTRODUCTION

3.3 TPPR System Key Components

3.3.1 Enclosures and Racks

TPPR can be mounted in various sizes of floor or wall mounted enclosures, or on 19” 5U racks. The floor mounted enclosures can be unventilated, naturally ventilated, or force ventilated. The fully sealed wall mounted enclosures can hold a controller or can be a remote terminal without a controller.

If using a 19” rack, the OEM or installer must ensure the installation is at least IP20 / Type 1 / Class 1 (grounded) to mitigate the risk of electrical shock.

Figure 18. TPPR Enclosures

3.3.2 TPPR Controller User Interfaces

The TPPR Controller is covered with a protective membrane and houses the touch screen user interface (UI), the alarm buzzer, the Accept and Reset buttons, and coloured LEDs for Power, Alarm, Fault, and Inhibit.

The controller has four access methods:

 Control Panel touch screen for normal system operation, maintenance and configuration  PC Configuration Software (optional licences) for secure maintenance and configuration over a VPN or cable  Webserver (optional licences) allows up to 5 people to securely view events and carry out basic system operation via

an Ethernet connection or the Internet

 Modbus option

Internal System Interfaces consist of:

 Two master relays that signal System Failure and System Fault  Connections for one SD Card and one USB drive  10/100 Mbps Ethernet connection (for networked interfacing)  Optional dual RS 485 Modbus RTU interface

INTRODUCTION

CAUTION

3.3.3 SD Card

TPPR is supplied with an installed 4Gb SD card, which users may replace with a larger capacity if desired. The SD card is used to store the event history of the system. TPPR logs all events and all changes to input readings. Note: The SD Card should remain inserted during normal system operation as the motherboard has limited data storage

capacity.

3.3.4 USB Port

The USB Host port allows users to save reports, backup and restore configuration.

Note: USB devices must be formatted to FAT32 only; other file systems are not supported and will not work. Note: The USB device is intended for maintenance and support operations only, and should be removed for normal use.

3.3.5 PC Configuration Software

This optional (downloadable) licensed software allows authorised users to configure some TPPR settings by using a remote PC over an Ethernet connection. This is more efficient as you can use a larger screen and keyboard.

More information is available in a separate PC Configuration Operating Manual.

3.3.6 PC Operating Systems

Windows 7 is supported for use with PC Configuration software.

Honeywell will not be held liable for any loss or damage caused by any security breach, no matter how caused.

Windows XP is considered a high security risk and is not recommended.

3.3.7 Webserver Software

This optional (pre-installed) licensed software allows users to remotely view live status, and analyse event history. Authorised users can also acknowledge, inhibit and reset I/O channels.

The Webserver supports up to 5 concurrent web clients. More than 5 clients can connect but performance may degrade. More information is available in a separate Webserver Operating Manual.

3.3.7.1 Supported Web Browsers

TPPR software is compatible with most current web browsers.

Part. No. 2400M2501_6 Touchpoint Pro 15 Technical Handbook

INTRODUCTION

CAUTION

3.3.8 Licences

The TPPR controller software does not require a licence. Please contact your local Honeywell supplier or distributor to obtain licences for the optional PC Configuration and

Webserver options. Refer to the PC Configuration or Webserver User Guides for details on installing and managing licences. TPPR will notify you shortly before the expiry of your current PC Configuration or Webserver licence. Licence expiry does

not affect local operation using the local controller’s interface.

3.3.9 TPPR Controller Hardware

Internally the Controller houses the Control Centre Board (CCB) and the Communications Board (COB). It also contains an SD Card slot, USB ports and an Ethernet / Printer port.

The CCB handles all functions related to the safety system operation, the Ring network, the LED indicators and buttons on the front panel, and the master system state relays. An optional backup CCB is available for multiple redundancy specifications.

The COB handles the remaining user interfaces – Touchscreen, SD, USB and the Ethernet and Modbus ports. The Communication Board is completely independent from the Safety Function of the system.

Always follow the correct procedure to remove/suspend/reinstall a licence if your system software or firmware is

going to be updated or repaired. Full details are contained in the PC Configuration and Webserver User Manuals.

3.3.10 TPPR Backplane

The TPPR Backplane is the power and information highway to which all of the TPPR modules are attached. There can be several backplanes in larger units, and they are installed within the DIN rail to which the modules are clipped.

The Backplane is available in four lengths (270 mm, 350 mm, 430 mm, 480 mm) to suit 5, 7, 9 or 10 I/O modules respectively, but the choice may be restricted by the size of the selected power supply option and the need to maintain adequate cooling space between modules.

Note: The DIN rail is 430 mm for a standard enclosure or 487 mm for the wide enclosure (10 x I/O) option.

Figure 21. TPPR Backplane

The Power Supply Unit (PSU) plugs into the green socket on the left hand side of the Backplane PCB, and it supplies power to the modules via the white connectors. The Ring Coupling Module (RCM) normally sits next to the Power Connector and handles all of the bi-directional communication between the CCB and the modules, again via the white connectors.

3.3.11 Ring Network

The Ring Coupling Module (RCM) and Input / Output (I/O) modules connect to a dual ring circuit so that they can communicate with the CCB through each other and through the RCM.

This enables fail-safe redundancy because, if one addressable module fails and interrupts the primary circuit, the addressable modules on either side of it can still communicate with the CCB via the backup ring circuit (see diagram below), and the CCB can identify which module has failed by knowing which addressable modules are still active.

Figure 22. TPPR Controller Typical Schematic

Part. No. 2400M2501_6 Touchpoint Pro 17 Technical Handbook

INTRODUCTION

For single cabinet installations, the Ring Network runs directly between the RCM and the Control Module. For Remote units, the network runs additionally over data cable between the Controller and all of the backplanes in the

system. The Ring Network is the only communication link required between the CCB and Remote Units (which have their own

backplanes, PSU and modules, but no Control Module).

3.3.12 TPPR Modules

TPPR is of modular construction so it can be easily expanded if required. The quantity and mix of I/O modules is optional and expandable.

 Power Supply Unit (PSU) modules accept AC 120 – 240 V at 50/60 Hz single phase and are available in three power

outputs: 24 VDC @ 120, 240 or 480 W.

 The optional DC-UPS is an uninterruptible DC power supply that links to and charges the optional 2 x 12 V Sealed

Lead Acid backup batteries.

 The optional Redundancy Module (RDN) can control two DC 20A power inputs. If one input supply fails, the

Redundancy Module will switch over to the other, maintaining the DC output. Alarm relays will open if one of the input supplies fails.

 The Ring Coupling Module (RCM) enables fail-safe bi-directional (ring network) communication between modules and

the controller. An RCM is required for each backplane in the system.

Various types of I/O modules are available, each containing four channels. A single TPPR system can contain up to16 input modules offering 64 input channels and up to 32 output modules offering 128 output channels.

MECHANICAL INSTALLATION

4 TPPR Mechanical Installation

Mechanical installation consists of physically mounting the TPPR Enclosure on a wall or, for floor mounted enclosures, on a suitable plinth, and then fixing cable trays in appropriate locations. Electrical Installation is covered in the next chapter.

4.1 TPPR Siting Considerations

TPPR can be installed in a wide range of wall floor and rack mounted enclosures but you should always consider the following when choosing locations:

 TPPR is specified for operation in ambient temperatures from -20°C to +55°C (TPPR Controller) or -40°C to +65°C

(no Controller). However the upper ambient temperature may be reduced dependent on the type and quantity of

installed components. It is the user’s responsibility to check the equipment rating plates for the true ambient range of

the installation as operation outside of this temperature range invalidates the warranty and certification.

 All enclosures and racks have individual Ingress Protection and type ratings. It is the user’s responsibility to check

individual rating plates for requirements.

 Only Zone 2 Div. 2 and Remote enclosures can be installed outside in unprotected locations. See Ch.20 TPPR

Specifications for further details.

 TPPR enclosures shall be protected from direct sunlight where exposure could cause the unit temperature to rise

beyond the specified operating limits, or where UV light could damage the Controller's membrane or Touch screen. It is the installer’s responsibility to ensure that the unit temperature does not rise beyond the specified operating limits.

 The TPPR wall mounted enclosure shall be installed only on a vertical surface and floor mounted enclosures shall be

installed only on a suitable weight-bearing plinth. Use the mounting fixtures supplied with the apparatus plus any specialist fixtures determined by the location, and follow the installation instructions carefully.

 The mounting surface should be flat, and strong enough to bear the weight of the TPPR system. Solid brick type

construction is recommended, while drywall / plasterboard, dry lined or timber framed type construction is not considered to be a suitable structural material unless appropriately reinforced. Take account of the contents and external cabling in addition to the weight of the wall mounted enclosure itself (check maximum enclosure weights detailed in the next section).

 There must be sufficient clearance to mount the wall mounted enclosure and be able to fully open the door. A

minimum clearance of 100 mm all round plus space for cable entries is required. The door hinge is on the left side. Beware of proximity to entries, exits and sloping ceilings.

 If more than one enclosure is to be used, ensure that there is sufficient clearance between the enclosures for cable

glands, mounting, cooling, door opening etc. This applies especially when mounting the backup battery enclosure beneath the TPPR Controller Enclosure.

 Ensure that the TPPR interface and touch screen can be freely viewed and reached. A wall enclosure touch screen

height of approximately 1.5 m is recommended for comfort, but the height of a floor mounted enclosure will be determined by the enclosure size and height of the plinth.

 Beware of siting TPPR in vehicle movement areas as personal injury may result. Erect safety barriers if this is

unavoidable.

 TPPR conforms to the requirements of European and other standards for EMC and RFI. It should not be installed in

close proximity to the antennae of high power radio, radar and satellite communication equipment, or in the vicinity of high voltage switching gear or overhead power lines.

 All signal cables should be shielded and bonded to protect them from stray or induced current.

4.2 Installing Wall Mounted Enclosures

The TPPR Controller and Remote units can be installed in a wide range of wall mounted enclosures.

The TPPR wall mounting brackets must always be installed in a vertical orientation as shown below.

Touchpoint Pro enclosures are heavy and unwieldy (refer to Specifications) and a single person lift is not

recommended. Before lifting the enclosure, consider and implement control measures to reduce the risk of injury.

It is the installer’s responsibility to select the appropriate fixings while taking into account the structure of the

mounting surface and the weight of the specific enclosure.

4.6 Installing the Battery Enclosure

Battery Enclosure installation is described in a logical sequence starting with assembling and mounting the optional battery enclosure followed by assembling and fitting the batteries.

Batteries are classified as hazardous goods and must be shipped in their own packaging. It is therefore necessary for the customer to install the batteries into the enclosure after the enclosure is securely mounted.

Note:

Prior to starting mechanical installation, it is recommended that you take into account that the DCUPS to Battery

Enclosure Circuit Breaker / Isolator cable is limited to a maximum of 5 m of 4 mm2 cable, and that you position the

enclosures accordingly before making any permanent fixings.

The TPPR Battery Enclosure must be installed in a Pollution Degree 2 environment as defined by IEC 61010-1

The TPPR Battery Enclosure is specified for operation in ambient temperatures from -20°C to +45°C. Operation

Ensure that there will be unobstructed access to the Circuit Breaker / Battery Isolator switch inside the enclosure,

The backup batteries have a limited shelf life, so please ensure that the batteries are connected and fully charged

Fix the battery enclosure securely to the wall before installing the 7.5 kg (12 Ah x 2) or 17 kg (27 Ah x 2) batteries.

 The TPPR Battery Enclosure should be installed only on a vertical surface and avoiding sloping surfaces. Only use

the mounting brackets supplied with the enclosure, and carefully follow the installation instructions below.

 The mounting surface should be flat, and strong enough to bear the weight of the Enclosure with the batteries

installed. Drywall / plasterboard, dry lined or timber framed type construction is not considered to be a suitable structural material, unless strengthened with additional supports or braces and/or special fixings. Take into account the weight of the batteries and external cabling in addition to the weight of the unit itself.

 The TPPR Battery Enclosure should have a clearance of 200 mm to either side, and there should be no heat sources

5.2.12 Assembling and Installing the Backup Batteries

Identify all required parts as follows:

 Two batteries – 12 Ah (small) or 27 Ah (large)  One positive cable, one negative cable and one cable with bayonet style fuse holder  Fitting kit of spade terminals, nuts, bolts and washers (used with 27 Ah batteries only)

Avoid shorting the battery terminals with metal or conductive objects, especially when connecting the cables or when

For the large batteries only, fit a supplied spade terminal to each battery terminal using the supplied fixings. The correct sequence for the fixings is – bolt, flat washer, battery terminal, spade terminal, flat washer, spring washer, nut, as shown below.

Note: Ensure that the terminals are positioned vertically and angled inwards or the cables will not fit.

The 12 Ah batteries fit into the offset mounting tray slots with the terminals to the front, while the 27 Ah batteries may require you to first remove the 12 Ah mounting tray (3 screws at the front and 2 at the back) before fitting the batteries with the terminals facing each other. Always fit the right hand battery first to avoid blocking access.

Normally the door opens to the left and the 27 Ah batteries are therefore positioned to the far right to avoid contact with the door hinge. However the door hinge can be changed to open to the right, in which case the 27 Ah batteries must be positioned to the far left instead.

It is advisable to remove the fuse before connecting the fused cable to the batteries, and to refit it only when all

5.2.17 Connecting to a Relay Output Module

The Relay Output Module (ROM) provides relay outputs to switch field devices such as sounders, beacons and actuators. In addition, an auxiliary voltage supply is available to provide power to such devices.

The relay contacts have a recommended range of ≥12 VDC, 10 mA to 250 VAC / 30 VDC 5A. The maximum contact current rating is 5 A per channel, with the additional limitation that the maximum contact current rating for the module is 8 A. An overcurrent protection device should be fitted to prevent higher current flowing through the relay contacts.

The auxiliary voltage supply provides DC 24 V (18–32 VDC) to the field devices at 1.5 A max. per channel, with the additional limitation that the total current drawn from the module must not exceed 1.5 A. The supply is short circuit protected – if a short circuit is detected the supply to all four channels is disconnected to prevent damage. The auxiliary voltage supply will be restored automatically when the cause of the short circuit is removed.

5.4 First Time Switch On

Before applying power to TPPR, ensure that all wiring and connections are correct and that all glands are tightened. Switch on the battery isolator switch (if DC-UPS is fitted) and then the main isolator switch. During the start-up, verify that the front panel LEDs illuminate in sequence and that the buzzer sounds. Verify that the LCD

functions correctly. During TPPR start-up check that the DC supply voltage is between 18 and 32 VDC at the Vaux terminals of a Relay Output

Module (preferably furthest from the power source) or at the V+ and V- terminals of an Analogue Input Module. TPPR initialisation typically lasts for 3 – 10 minutes depending on the number of channels and sensors in the system. TPPR will then display the System Status screen, indicating the current status of the system. Note: AIM-mV Bridge channels will be in Inhibit mode until calibrated. In addition, some mA or mV channels may have a

‘power-up’ delay programmed, which means that those channels could remain inhibited until the end of the delay, i.e. up to 5-mins.

6 Modbus Installation (Option)

6.1 Introduction

The optional TPPR Modbus Interface provides a facility for digital communication between the TPPR and an external computer system. Modbus is a well-supported digital data communication protocol that provides a standardised set of data communication protocols.

The principal features of the Modbus Interface are:

 Operates as a Modbus Remote Terminal Unit (RTU) slave device node.  Supports functions 02, 03, 04, 06 and 16 of the Modbus protocol.  Provides sensor gas readings and alarm status for Fault, Inhibit, Warning, A1, A2, A3, STEL, LTEL and Rate alarms

from all input channels in the system.

 Supports commands to Inhibit, Reset and Acknowledge for all channels in the system, as well as Global Reset and

Global Acknowledge.

 Dual RS485 half-duplex communication with multi-drop capability.  Asynchronous serial link configurable for baud rate and parity.

Maintenance Note: The Modbus broadcast commands are not supported and will be ignored.

6.2 Programming the Host

The host computer system must be programmed to interpret the signal and status data from TPPR as there is no defined standard Modbus format for the communication of data from gas detection systems.

It is recommended that the host computer system should, as a minimum, be programmed to use Function 02 to collect alarm and status data from all TPPR channels.

Full details of the Modbus protocol can be found in the Modicon Modbus Protocol Reference Guide PI-MBUS-300 available from www.modbus.org.

Some transceiver manufacturers incorrectly use RS-485 pin A as data positive and pin B as data negative. You may

have to swap over TDA and TDB (A in and B in) if your Modbus does not work as expected.

6.3 Addressing Conventions and Register Values

The addressing conventions and register values used follow those set by Modicon. The first digit of the on-board memory address refers to the data type stored in the register and therefore defines the Modbus function command that should be used when polling it.

1xxxx – The Input Status Register addresses record the individual channels’ status. They are read using Modbus Function

02. 3xxxx – The Input Register addresses record the current input values of the individual channels. They are read using

Modbus Function 04. 4xxxx – The Holding Register addresses have two purposes. One range of addresses is used to send commands and

receive the results of those commands. The other address range is used to send queries and store the results of those queries. They can be written singly using Modbus Function 06, written as a block using Modbus Function 16 and read using Modbus Function 03.

4. Enter your local service contact details

7.4 Configuring the Touchpoint Pro TCP/IP Address and Printer

Each Touchpoint Pro Controller must be allocated its own unique static TCP/IP on your network and, for security reasons, this should never be the manufacturer’s default IP address.

Touchpoint Pro requires a secure physical network connection prior to the user being able to edit or save the

TCP/IP configuration. If the controller is configured with a duplicate IP address (i.e. of other users already logged

onto the network), you will not be able to save its TCP/IP settings until the duplicate address is resolved.

TPPR must be protected against cyber-threats. Always consult the site IT department or a professional IT consultant

before connecting TPPR to Computer Networks. Refer to the Touchpoint Pro Security Guide.

7.4.1 How to Configure the TPPR’s TCP/IP Address

If the TPPR TCP/IP address is not already configured, or still has the manufacturer’s default address:

1. Obtain a secure static IP address (typically from your site IT department). You will also need the default gateway address and subnet mask.

2. Using the TPPR Touchscreen, log in as an Administrator and then select:

Tool Box>Password>Global Settings>TCP/IP Settings.

3. Select Edit and enter the TPPR’s new IP address.

4. Check and edit the subnet mask to the one used on your local area network.

5. Check and edit the IP address of the network gateway if required.

6. Save the settings.

The TPPR checks that it has a working network connection, and checks that the programmed IP address is unique before it saves the new address settings.

A potential conflict could occur if another network device has the same IP address but is not currently connected.

This can happen when rarely used items are switched on or connected to the network.

7.4.2 How to Configure the Printer

TPPR can print to a networked printer. To enable printing, enter the IP address of the required printer.

7.5 Enabling TPPR’s Remote Connection Port

The Remote Connection port is a software port that shares the TPPR Ethernet connection. It is used by the:

 PC Configuration software  Webserver Certification Tool (WSCT)

As a security measure, TPPR will only allow a maximum of 2 hours connection to the Remote Connection port in a single session. The user is automatically disconnected after two hours.

To use the remote software, enable the port, as described below, and then connect and log in using the remote software. Users may log in and out as required while the port is enabled.

Note: The port can only be enabled from the controller touchscreen. See the PC Configuration Operating Manual for further details.

7.5.1 End of session warning

Logged in users will get a warning message 10 minutes before the connection is terminated, which will give them the option of saving, confirming or discarding their edits before the connection is terminated.

Users who log in after the final 10 minutes will be told how long they have left before the connection is automatically closed. If a configuration session is still active when the port is closed, unsaved edits will be lost and the module being edited may

remain in Configuration mode with channels inhibited. It may be necessary to log in to the System Configuration screen and set the module back to Normal mode.

7.5.2 Additional Time

If additional time is required, the port may be immediately enabled again for a further 2 hours.

7.5.3 Enabling the Port

To enable the port, log in from the controller and navigate to the TCP/IP Settings screen as described in section 7.4. From the tools menu, select Enable 2 hrs.

7.5.4 Disabling the Port

To disable the port, log in from the controller and navigate to the TCP/IP Settings screen as described above. From the tools menu, select Disable.

The Remote Connection port is automatically disabled when the remote user session is disconnected, either manually or following an inactivity timeout, or when the 2 hour session expires.

7.5.5 Webserver and Printer

The Webserver and printer use the same Ethernet connection but do not require the Remote Connection port to be enabled.

7.6 How to Print Active Events

Events recorded to the system Event Log can be sent concurrently to a networked printer as hard copy. All events are then sent to the printer.

Note: To enable printing, ensure the printer is connected to the Ethernet port and a valid TCP/IP address is being used. Refer to section 7.4.2.

To change print settings:

1. Login as an Administrator or Engineer

2. From the System Status screen select the Tool Box icon then Panel Configuration

3. Select Print Active Events

4. Select Enabled or Disabled and then Apply

When enabled, each event will be sent to the printer as it occurs.

CALIBRATING GAS SENSORS

CAUTION

any TPPR testing or calibration.

CAUTION

DANGER

An ‘Over Range Warning’ may indicate a rare but potentially catastrophic event that must be fully investigated.

When Over Range Warning is programmed, TPPR displays a warning on the Touchscreen that requires an

additional Reset operation before the alarm may be cleared.

8 Calibrating Gas Sensors

All gas sensors must be calibrated on commissioning, on replacement, at regular intervals specified in their user manuals, or when dictated by usage. (Touchpoint Pro can be programmed to generate periodic calibration reminders. See Ch. 9.2.16 &

9.3.16 for information on Calibration Reminder Settings for AIM-mA and AIM-mV settings respectively.) Note: Calibration data is not retained following a restore operation and calibration reminders may require updating following

recalibration. The basic calibration procedure is to first clear the sensor of any target gas and then introduce a known concentration of a

test gas followed by a rest period to ensure that the sensor goes back to normal. Note: Oxygen (O2) calibration is done at the sensor while Carbon Monoxide (CO) calibration should follow the user’s local

procedures.

Ensure that executive actions/outputs are inhibited and alternative safety arrangements are made before starting

It is expected that mA sensors will be calibrated at the sensor or field device. The TPPR mA calibration is not

intended to calibrate the sensor, but to align the TPPR 4-20mA current loop with the sensor current loop zero and

span settings.

The TPPR mA calibration should not be used to calibrate the sensor zero and span, or to compensate for

deficiencies in the sensor or transmitter calibration. Failure to observe this can result in significant accuracy errors.

8.1.1 Calibration Definitions

 Clean Air describes ambient air that has a nominal zero concentration of the target gas being sensed.  First Span is the name given to the first gas span reading of a new mV sensor, which is used to monitor the sensor’s

sensitivity over time.

 Over Range Warning is when a mV sensor exceeds 100 % of Full Scale Deflection (100 %FSD). A gas over range

condition can cause catalytic sensors to operate outside of their working range and incorrectly indicate low gas concentrations when hazardous concentrations may be present.

 Span gas is a compressed gas containing a specified concentration of the target gas being sensed.  Span is the gas concentration reading at which calibration is carried out, typically at 50% of full scale.  Zero Gas describes a test gas that has a zero concentration of the target gas being sensed, and it may be a different

gas for different sensors.

CALIBRATING GAS SENSORS

CAUTION

to ensure accurate and consistent testing and calibration.

8.2 Calibrating AIM-mV Input Channels

Touchpoint Pro supports routine calibration of mV sensors. TPPR can be programmed to display calibration reminders at calibration intervals, e.g. annually or every six months.

It is compulsory to calibrate the sensor when a channel has been newly commissioned, when the sensor bead current has been changed, or if the system configuration has been deleted.

TPPR warns when the output from a sensor reaches 50% of its initial value and should be replaced. The First Span

calibration option is used to record the initial output level of a new sensor. Note: The maximum allowable span signal is 300mV for 100% FSD. This figure is scaled by the Span Gas Concentration

that has been entered i.e. 50% span gas concentration limits the maximum mV reading to 150mV.

Note: TPPR mV Analogue Input channels (AIM-mV) will remain in the Inhibit state until they are calibrated. Note: Zero and Span may be calibrated independently. When replacing a sensor, both Zero and First Span calibrations shall

be carried out.

Channel calibration is compulsory after changing the bead current (or catalytic sensor) of an AIM mV channel, and

8.3 Calibrating AIM-mA Input Channel Loops

Touchpoint Pro supports both gas calibration of mA sensor and loop calibration of the transmitter 4-20mA current loop. TPPR can be programmed to display calibration reminders at calibration intervals, e.g. annually or every six months.

In general gas calibration should be carried out at the sensor, using the sensor’s inbuilt calibration. Gas calibration of a

sensor from TPPR should only be carried out on sensors without this capability. The procedure is similar to the mV calibration above. For loop calibration the Zero and Span (4mA and 20mA) currents

should be set using the transmitter’s Force functions where available.

Wherever possible the TPPR mA loop should always be calibrated by forcing signal levels at the sensor /

transmitter. Any gas calibration must be carried out at the field device according to the manufacturer’s instructions.

Disable or inhibit any operations or actions that may result from gas readings before starting this test.

9.1 General Considerations

You should consider the following scale before configuring any system parameters. Note that Over Range Warning and Full Scale Exceeded peak values are shown on the trend display.

A Over Range Warning may mean that the catalytic sensor has been flooded by a gas concentration beyond its

design capacity, which could indicate that a potentially catastrophic situation has occurred. It is advisable to

This is the delay time before a channel returns to normal operation if the Power-On Delay or the Fault Recovery Delay is enabled.

9.2.14 Rate Alarm Settings 1

The Rate of Change Alarm is triggered when a specific rate of rise or fall is observed (the Rate Alarm Trigger can be set as Rising or Falling).

The Alarm Level and the Alarm Interval can be configured. E.g. If the Alarm Level = 10 %LEL and the Alarm Interval = 5 s, the Rate Alarm triggers if the concentration has risen by 10 %LEL within 5 s.

The rate alarm is calculated from the displayed reading. Note: If zero suppression is used it has the effect of sensitizing the rate alarm. It is recommended to set the rate alarm to

twice the suppression band value to avoid nuisance alarms. Access Level: Engineer

Note: Rate Alarms should always be set to Latching or connected to a latching input on other equipment. A non-latching alarm will only be displayed whilst the rate is exceeded. The alarm will reset when the gas concentration achieves full scale or the gas rate falls below the set rate.

9.3 Analogue Input Module mV Bridge Parameters

The Analogue Input Module mV Bridge has the option to use the sensor catalogue (basic / extended), configure a custom channel, or copy from a configured channel (basic / extended).

Note: When making changes using extended options, it is the user’s responsibility to determine whether other settings have been affected and to make any corresponding changes.

If a basic configuration is selected, only the first two screens detailed below will be used (Commission Channel and Field Device Selection). The rest of the configuration will be programmed automatically, either from the sensor catalogue or from the channel that is being copied.

Note: If a channel is configured from the sensor catalogue, it is possible to edit individual settings afterwards. Note: For catalytic bead type detectors, the Touchpoint Pro controller is necessary to complete the measuring circuit.

Therefore all commissioned mV channels remain in Inhibit state until they are calibrated.

The Digital Input Module (DIM) has the option to configure a blank channel, or copy from a configured channel. Note: If a channel is configured by copying from another channel, it is possible to edit individual settings. Digital Input channels may be configured to generate Alarm, Fault or Warning events. Alternatively, using the Remote

Interaction options, they may be used to remotely Reset, Inhibit, or Acknowledge one or more selected channels.

9.4.5 Group Remote Interaction Settings

Access Level: Engineer If any of the remote interaction options are enabled above, select Add / View Group Member to choose the channels to

associate with the Reset, Inhibit or Acknowledge action. Configuration is simplified if the required channels are all commissioned before configuring the Remote Interaction options.

 Channels can be assigned to more than one interaction group.  A DIM channel assigned to carry out a remote interaction is not available to take part in any other interaction group.

Note: The Remote Group Settings screen may be displayed when Remote Interaction is not selected, and should then be ignored.

9.4.6 Use with Catalytic Sensors

Since a remote user cannot see information on the touch screen, Remote Interaction should be used with caution. In particular, Remote Reset should not be used with catalytic sensors.

Remote reset should not be used for catalytic sensors, since gas could still be present even though the sensor

reading has dropped. Conditions at the field device should always be investigated before resetting an alarm.

9.5.3 Cause and Effect Type Selection

A Relay Output channel can be configured as a ‘Master’ relay, which activates if any specific condition is present anywhere in the system (e.g. Alarm 1), or as a ‘Normal’ relay, which activates according to the programmed Cause and Effect matrix for that channel.

9.5.4 Output Type

Select the required Output Type, Master or Normal, as required.

9.5.5 Event Selection for Master Channel

The master selection option uses a screen similar to that below:

For example, if AL1 is selected, the output will activate if any configured channel reports an AL1 condition. Similarly, if Fault (FLT) is enabled, the output will activate if any channel reports a fault.

Multiple conditions may be enabled, for instance an output may be configured to activate on any alarm and any fault.

9.5.6 Zoned Outputs

To configure an output to monitor a zone, use a Normal cause and effect type, as described below, and associate the channels in the required zone with an output channel.

9.5.7 Input Channel Preselection for Cause and Effect Matrix (Normal Relay Channel)

Access Level: Engineer This screen helps to reduce the number of channels listed in the Cause and Effect (C&E) Matrix to only the channels the

operator wants to map. Select the required input channels to link to this relay output channel by checking the box next to the channel ID. The details of this link (Alarm1, Warning…) will be assigned in the next screen.

Note: If you used the option to copy from a configured channel, the input channels linked to that channel will be automatically pre-selected. The alarms, faults etc. associated with these channels may be disabled in the next screen if required.

9.6.1 C&E Matrix Explanation

The ‘ID/Location’ column shows the channels selected in the previous pre-selection screen. If an output is controlled by a single input channel, only one row is shown.

The events that may be selected for each input are shown alongside. Any combination of events may be selected. Any of the selected events will cause the output to activate.

The total number of selected input channels is shown at the bottom of the screen. If an input was selected at pre-selection, but no events are programmed for it, the input is discarded when the configuration is saved.

The At least One Alarm and Vote Count controls are described in the following sub-chapters. Note: To remove an unwanted input channel from the cause and effect matrix, for instance from a copied channel, uncheck

all the events for that input channel.

9.6.2 STEL, LTEL and Rate Alarms

When an input channel is used for time weighted alarms it is linked to the AL1, AL2 and AL3 events column:

 AL1 is used for STEL  AL2 is used for LTEL  AL3 is used for Rate Alarm

The cause and effect matrix is evaluated in the same way as for threshold alarms.

9.6.3 Multiple Inputs

An output may be associated with one or more events per input channel in the cause and effect matrix. When more than one event is associated, voting is used to determine how the output responds to the selected event combination.

9.6.4 Voting

Voting allows a user to select how many input channels must have an active event before an output will change state.

In the example above, an output is associated with three input channels in the cause and effect matrix. The vote count is set to two. The output will activate if at least two of the three input channels have an active event.

In the example, if the vote count is set to 1, any one or more input channels with an active event will cause the output to activate. Similarly, if the vote count is set to 3, each input must have at least one active event to cause the output to activate.

9.6.5 Vote Compensation (Vote Reduction)

If a voting input is inhibited or has a fault, it can prevent a voted output from activating as expected. Vote compensation may be used to take account of failing or inhibited inputs.

In the example above, 3 inputs are required to be in an alarm state to activate the output. If, for instance, two inputs are in a fault or inhibit state, only two inputs are able to vote. The output cannot activate, even if both remaining inputs alarm:

It is possible to avoid this situation and require at least one real alarm condition to be present before the output activates. Check the ‘At least One Alarm’ checkbox:

The output will not activate unless one or more input channels indicate an alarm, as shown in the examples below:

9.6.7 Controller Display and LEDs

The cause and effect matrix controls the state of programmed outputs. Alarms, faults and warnings are reported independently on the controller front panel and are not affected by cause and effect settings.

9.6.8 Alarm Update

Alarm Update is used to indicate that one or more alarm events included in a cause and effect matrix has occurred since any previous events were acknowledged.

For instance:

1. A sensor detects that an AL1 threshold has been exceeded

2. The operator accepts the AL1 alarm

3. The sensor detects that the gas level has risen and the AL2 threshold has been exceeded

4. The system must indicate that a change has occurred.

Or:

1. A sensor in a voting group indicates an alarm

2. The operator accepts the alarm

3. A further sensor indicates an alarm

4. The system must indicate that a change has occurred.

And so on…

The alarm update responds to events associated with an output by a cause and effect relationship. If an event occurs but is not included in the cause and effect logic, the controller will respond normally and indicate the event but the Alarm Update will not respond to it.

For instance, if AL1 and AL2 of an input channel are configured in a cause and effect matrix, but AL3 is not:

1. The signal exceeds the AL1 level – alarm update responds to the event; The operator accepts the alarm

2. The signal exceeds the AL2 level – alarm update responds to the event; The operator accepts the alarm

3. The signal exceeds the AL3 level – the event is still reported on the controller but alarm update does not respond

Note on Rising and Falling Levels Alarm Update responds to events in increasing order of severity, for instance rising gas levels on a toxic or flammable

sensor. Alarm Update does not respond to a gas level changing to a less severe condition.

9.6.9 Action on Events

The output action on a new event may be set to Steady or Pulsing. The pulsing output may, for instance, be used to directly control a flashing lamp.

The Pulsing option is only available when the alarm update function is enabled.

9.6.10 Action on New Event – Steady

The output channel operation is as follows:

9.6.11 Action on New Event – Pulsing

The output channel operation is as follows:

9.6.12 Operation of Reset

Reset operates normally: e.g. if the alarm condition is still active, the alarm(s) cannot be reset and a warning is displayed. The alarm may be reset when the alarm condition is cleared.

9.6.13 Notes on Use

An output configured for Alarm Update does not indicate the alarm status; instead it indicates that one or more events have not been acknowledged or that a new (unacknowledged) event has occurred. The output will silence when all contributing alarms are acknowledged.

9.6.14 Typical applications

 Pulsed Relay on Activation (usually flashes a Lamp) and goes ‘Steady’ on accept (non-flashing lamp): Starts

‘Pulsing’ if a further activation is seen.

 Steady Relay on Activation (usually starts Siren) and goes ‘OFF’ on accept (silent): Starts ‘Steady’ if further

activation is seen.

9.7 Control of Output Channels – Priority

Output channels can be controlled via various options. In addition to the state of inputs and the cause and effect matrix, the output may be inhibited or forced to a specific state.

The control inputs are evaluated as shown below. Inputs to the right will override inputs to their left, e.g. Output Inhibit will override the input state, C&E logic and the alarm update settings but will be overridden by an Output Force condition.

9.8 Power Supply Unit Parameters

Four Power Supply Unit inputs are accessible from the System Setup screen. They are provided to monitor and report the status of power supply unit status relays. The input status is reported on the controller, and may be selected as Alarm, Fault or Warning. These inputs may not be assigned to a relay output but will activate Fault or Warning Master outputs.

The PSU inputs are not shown on the Inputs screen. They may be Acknowledged and Reset but not Inhibited. If not required for this purpose they may be configured to act as global Acknowledge, Reset or Inhibit inputs. Refer to section 5.3.3 for connection details.

WARNING

STEL AND LTEL HISTORY IS RESET WHEN POWER IS REMOVED. THE READING WILL REQUIRE AN

INITIALIZATION TIME AFTER POWER IS RESTORED.

10 Configuring STEL and LTEL Alarms

TPPR mA channels may be configured as STEL and LTEL alarms. The same channel may be used for both STEL and LTEL.

STEL and LTEL are always rising alarms, and are latched by default. Note: STEL and LTEL Alarms should always be set to Latching. A non-latching alarm may reset before the appropriate

actions can be taken. A channel programmed for STEL and/or LTEL may not be used for threshold alarms (A1, A2, and A3). When connected to

an output cause and effect matrix, STEL replaces A1, LTEL replaces A2, and the rate alarm replaces A3. In common with other alarms, STEL and LTEL alarms cannot be reset if an Over Range Warning is active. The Over Range

Warning must be cleared first.

10.1 STEL Operation

The controller takes four gas readings every second. Readings are rolled up and averaged over the configured STEL interval.

The averaged STEL value is updated every half minute and compared against the programmed STEL limit. The STEL alarm is activated if the calculated result is above the programmed threshold. The average is calculated continuously while the system is powered. The averaged value is initialised to a default value:

 when power is applied  when there is a change in STEL configuration  when the alarm is reset by a user

The default value is equal to the Gas Range Minimum configured for the channel. Following initialisation, the calculation requires one STEL interval to stabilise.

When the channel is inhibited, the controller continues to calculate the average but uses the above default value instead of the sensor value. The channel will not alarm while inhibited.

The alarm cannot be reset until the averaged value falls below the programmed threshold. The time to wait before you can reset will depend upon the degree of ventilation, the residual gas levels and the programmed settings.

Note: The STEL Interval is configurable from 5 – 20 minutes in 5 min. increments, from 20 – 40 minutes in 10 min. increments and finally to 60 minutes.

CONFIGURATION

WARNING

STEL AND LTEL HISTORY IS RESET WHEN POWER IS REMOVED. THE READING WILL REQUIRE AN

INITIALIZATION TIME AFTER POWER IS RESTORED.

10.1.1 STEL Algorithm

TPPR calculates the moving half-minute time-weighted average (HM_TWA) of the selected STEL time interval as:

STEL = (HM_TWA1 + HM_TWA2 + HM_TWA3 → + HM_TWAN) / STELN

Where:

 HM_TWA1 = 1st Half Minute TWA  HM_TWA2 = 2nd Half Minute TWA  HM_TWAN = Nth Half Minute TWA  STELN – Number of Half Minute TWA Samples received in the chosen STEL interval (1a – 1g above)

The CCB then uses the resulting half-minute TWA for STEL moving average calculations:

HM_TWA = (GC1 + GC2 + GC3 → + GCN) / N

Where:

 HM_TWA = Half Minute TWA  GC1 = 1st Gas Concentration Sample  GC2 = 2nd Gas Concentration Sample  GCN = Nth Gas Concentration Sample  N = Number of Samples received in half Minute

10.2 LTEL Operation

The controller takes four gas readings every second. Readings are rolled up and averaged over the LTEL interval, which is fixed at 8 hours.

The averaged LTEL value is updated every ten minutes and compared against the programmed LTEL limit. The LTEL alarm is activated if the calculated result is above the programmed threshold. Once started, the average is calculated continuously while the system is powered. The averaged value is initialised to a default value:

 when power is applied  when there is a change in LTEL configuration  when the alarm is reset by a user

The default value is equal to the Gas Range (Min) configured for the channel. When the channel is inhibited, the controller continues to calculate the average but uses the above default value instead of

the sensor value. The channel will not alarm while inhibited. The alarm cannot be reset until the current gas level reported by the sensor is below the programmed LTEL alarm level. The

time to wait before you can reset will depend upon the degree of ventilation and the residual gas levels.
