RTK Series 725 Annunciator

1. Introduction

The RTK 725 Series alarm annunciator is used to provide visual and audible warning that a process has gone beyond set limits or to provide status only indication. The annunciator is manufactured from universal cells, each 60 x 60mm, which can be assembled in an array to provide the number of rows and columns required to suit individual panel designs.

Each cell within the annunciator is able to contain either:- one large, two medium or four small alarm windows, which can be illuminated by conventional 28V filament lamps or by “fit and forget” LED assemblies.

The assembled unit is fully field programmable which allows the user to enable a number of predefined features to control the operation of the annunciator with regards to alarm sequence, horn groups, common alarm groups or optional Modbus communications.

Selection of features is on a per channel basis with no special tools or programming knowledge required. All programming is carried out from the front of the unit using the integral pushbutton / programming module, which allows changes to be easily made during commissioning or at a later date after the equipment has been installed.

Large and medium window version alarm cards are fully interchangeable within the annunciator, on small window versions an additional card type is used for the 2nd pair of alarm channels but cards of the same type remain fully interchangeable.

Reliability of operation is increased over conventional annunciators as each alarm card is fitted with its own application specific integrated circuit (ASIC), which is capable of complete system control. During initial power up one of the alarm cards will automatically act as a master controller with regards to flash rates etc and in the event that this card fails or is removed another card will automatically take over the role of master controller.

The standard unit is supplied with five integrally mounted common output relays, which are used to provide 2 horn relay outputs, 2 group relay outputs and a multifunction relay output with programmable function.

Additional options exist for more complex requirements including integrally mounted signal duplicating relays on a per channel basis, bi-directional RS485 serial communications link and user selectable time delays on each channel.

Accessibility for normal maintenance, lamp/LED changes, legend/filter changes and programming is accomplished from the front of the panel without the use of special tools.

These voltages are shown on the individual alarm card and X is used to indicate which version has been supplied. Alarm cards ar e plugged into the rear of the annunciator and once inserted automatically connect to a pre-tested passive display motherboard.

3.8 Pushbutton / Programming Module

The pushbutton/programming module is located in the bottom right hand corner of the annunciator when viewed from the front unless otherwise specified. It has a power-on LED, integral audible and six pushbuttons to cover all of the possible sequence combinations. The six pushbutton are:- Lamp Test, Functional Test, Mute, Acknowledge, Reset and First Reset

Page 12

RTK Series 725 Annunciator

3.9 Pushbutton / Programming Module Options

The pushbutton/programming module is normally integrally mounted within the annunciator however if required it can be supplied as a stand alone item suitable for panel mounting, DIN-rail mounting or wall mounting.

3.10 Fully Field Programmable

In addition to controlling the alarm sequence the pushbutton module is also used as a configuration tool to programme the required features on the annunciator. To access the programming functions the pushbutton fascia must be hinged down to reveal a configuration switch (labelled CONF) located on the inner face of the assembly. Once the unit is in the CONF mode the user is able to enable or disable a range of pre-defined features and options. The dual function pushbutton assembly allows the user to enable any of the 25 embedded features on a per channel basis without having to remove the power to the annunciator or to remove light-boxes, back-planes or alarm cards.

All programmed information is stored in EEPROM, with a minimum 20-year retention, giving repeatability and reliability without the need for battery backup.

Note:- Alarm sequences will operate in accordance with any of the standard sequences defined in the ISA publication "Alarm Sequences and Specifications S18.2 - 1979 (R1985)"

3.11 Expandability Using SI/O Cards

System expansion cards type SI/O are used in applications where either a single pushbutton / programming module is linked to a number of alarm annunciators or when large cabinets require additional power distribution terminals to evenly distribute the logic power. In addition to the logic power terminals the SI/O card is also equipped with IN and OUT ribbon cable sockets to allow ribbon cable and connectors to be used to link common control functions between annunciators.

Page 13

RTK Series 725 Annunciator

3.12 Sleep Mode

Sleep mode is typically used in sub station applications where the visual and audible outputs are disabled during unmanned periods to reduce the drain on the associated station batteries. Whilst in sleep mode the logic of the annunciator will continue to react in the normal way including the operation of common alarm relays, watchdog relay and optional signal duplicating relays, only the drive signals to the lamp and audible drives are disabled.

Before sleep mode can be enabled a jumper link must be pre-set on the SPR card located inside the pushbutton / programming cell. To gain access to the SPR card first remove the back-plate on the SPR module and then remove the associated circuit card assembly using a flat blade screw driver to gently lever the assembly out using the white nylon pillar. Once the card has been removed locate the 3 pin header marked FR and SP which is located on the lower of the two cards and check that the 2 way shorting bar is in the SP position as shown below. Once the jumper has been placed into the correct position and the card assembly placed back into the annunciator the unit can be set to sleep mode using a remote mounting normally open maintained switch with one side of the switch connected to +V (+24VDC) and the other side of the switch connected to terminal FR located on the rear of the pushbutton / programming cell. Whilst the switch is maintained in the closed position the unit will remain in sleep mode.

Note: - All normal pushbutton functions are inhibited during sleep mode to ensure that the operator can view any alarms that occur as soon as the unit is returned to its normal operational state.

3.13 Automatic Mute Or Automatic Acknowledge

Each annunciator is equipped with an integral timer that can be enabled to allow the user to automatically mute or acknowledge alarms after a pre-set time delay. To set the automatic mute or acknowledge feature the pushbutton / programming module must be hinged down by inserting a small flat blade screw driver into the recess on the upper face of the associated surround bezel and gently levering the pushbutton assembly forward to reveal the information plate which is visible on the inside face of the module. The two pozidrive screws and washers in the centre of the plate should be removed to allow access to DIL switch SW7, which is used to set the unit to automatically silence or acknowledge and to set the required time delay.

3.14 Integral Audible Alarm

Each annunciator is equipped with an internal 3.5kHz 95dB(A) audible located behind the integral pushbutton module. The audible is supplied with an adjustable volume control using a single turn potentiometer. The potentiometer can be accessed by hinging down the integral pushbutton module using a small flat blade screwdriver in the slot of the surround bezel. The potentiometer is located in the top right hand corner of the cell as shown below. On systems with channels configured to activate either the urgent or non-urgent audible relays it is important to note that the internal audible will only operate on channels set to operate the critical audible relay HNA (see Function F23).

3.15 Remote Pushbutton Inputs

Remote pushbuttons can be connected to the P725 SPR module either in place of or in addition to the integral pushbuttons or to allow multiple annunciators to share common pushbuttons for example a common mute pushbutton mounted in the operator desk console. The pushbuttons should be of the normally open, momentary type and it is recommended that if long cable runs are required through electrically noisy environments a screened cable is used with the screen connected to a suitable instrument earth at one end only. Please note:- When the annunciator is in the configuration mode with the CONF switch in the ON position all integral or remote pushbutton inputs are disabled until the unit has been returned to its normal operating state.

All alarm inputs are provided with fully isolated inputs using optical couplers and a transient filter is built into the input circuitry so that low voltage interference will be ignored.

4.2 Standard Input Configuration

The standard Series 725 annunciator can be set to operate from volt free signal contacts that are either normally open or normally closed.

 Setting function F1 to the off state conditions the input to accept a normally open contact.  Setting function F1 to the on state conditions the input to accept a normally closed contact.

Please note:- when using the Customer adjustable response time options AD* on P725 Annunciator supplied after March 2009 Function F1 should always be set to “OFF” and switch SW2 should be used to set the Input to normally open or normally closed as described in Section 24 of this manual

4.3 Signal Supply Voltage

On standard units an internally fused 24vdc signal supply (+VC), derived from the 24VDC logic supply (+V), is distributed to all of the common terminals marked “C” which are located to the right of each signal input terminal as typically shown below.

4.4 Input Voltage Options

Annunciators can be supplied suitable for connection to direct powered inputs as an option with the signal supply voltage being supplied from outside the annunciator by others. In this application the logic supply (OV and +V) and signal supply (OVC and +VC) inputs located on the SPR module are independently wired and fully isolated from each other.

VOLTAGE

Standard 24V AC/DC

FC048 48V AC/DC FC125 125V AC/DC FC250 250V AC/DC

4.5 Input Time Delay – Option AD*

As an option each channel can be provided with a potentiometer, which allows the user to select a time delay to prevent the alarm from occurring unless it has been present for a pre-defined period.

Option AD1 = Adjustable Delay Range 5 – 50 ms Option AD2 = Adjustable Delay Range 20ms - 2 seconds Option AD3 = Adjustable Delay Range 5ms – 5 seconds

4.6 Input Wiring Segregation

Field contacts are often great distances from the annunciator it is therefore advisable to run the contact cables separately from circuits carrying heavy currents and/or high voltages to minimise the affects of induced voltages.

4.7 No Master Module

Each dual channel alarm card is equipped with a dedicated application specific integrated circuit (ASIC). System control is automatically allocated to one of the alarm cards during power on and if this card is removed, damaged or fails (apart from catastrophic failure), another card will automatically take over the common control functions. This method of operation eliminates the need for a traditional style common services/control module and removes common failure points thus increasing reliability.

5. Outputs

5.1 Common Outputs

All series 725 annunciators are equipped with five common output relays located on the upper card of the SPR module. (Part no CB4642POP1).

As standard all five relays are factory set to be normally energised and will de-energise when activated.

Each relay is equipped with volt free contacts for customer use, which can be selected to be either normally open or normally closed in the non-alarm state per the following table.

To change any of the settings the relay card must be removed from the system as described below

1. Remove Power From the annunciator

2. Remove the t wo green terminal blocks which provide customer terminations on the rear of the pushbutton cell.

3. Remove the plastic protection cover on the rear of the pushbutton cell by releasing the tabs on either side of the cover

4. Remove the t win card assembly from the rear of the unit. (A flat blade screwdriver can be used to gently lever the assembly from the cell by placing the blade under the white stand off pillars and the side of the cell).

5.2 Critical Horn Relay - HNA

When an alarm occurs the horn relay will change state and remain in the alarm condition until the mute or ack pushbutton has been pressed. Each channel can be set to operate the critical horn relay as required. Please note:- Channels set to operate the critical horn relay will also operate the integral audible alarm.

5.3 Non-Critical Horn Relay - HNB

When an alarm occurs the relay will change state and remain in the alarm condition until the mute or ack pushbutton has been pressed. Each channel can be set to operate the non- critical horn relay as required. Please note:- Channels set to operate the non-critical horn relay will not operate the integral audible alarm.

Page 22

RTK Series 725 Annunciator

5.4 Critical Group Relay - GPA

When an alarm occurs the relay will change state and remain in the alarm condition until all alarms in the group have returned to normal and the logic has been reset. Each channel can be set to operate the critical group relay as required.

5.5 Critical Group Relay - GPB

5.6 Reflash Critical Group Relay - GPA

When an alarm occurs in the critical group the relay will change state and if reflash is set any subsequent alarm occurring in the same group will cause the relay to drop out for 0.5 seconds. Each channel can be set to reflash the critical group relay as required.

5.7 Reflash Non-Critical Group Relay - GPB

When an alarm occurs in the non-critical group the relay will change state and if reflash is set any subsequent alarm occurring in the same group will cause the relay to drop out for 0.5 seconds. Each channel can be set to reflash the non-critical group relay as required.

7.2 System Capacity

The maximum number of alarms available within a single annunciator is dependent on the maximum number of cards the system can address. This is fixed at 128 two channel cards, making the maximum system size for all window sizes 256 channels.

In applications where a number of separate annunciators are linked together to form a common system the max capacity for the whole system will remain at 256 alarms.

8. Alarm Sequences

8.1 Summary

Each channel within the annunciator can be set to operate in a pre-defined manner in accordance with internationally recognised standards ISA-S18.1 1979 (R2004) alarm sequences. Typically when an alarm occurs the associated window will flash and the operator uses specific pushbuttons to control the audible alarm and associated lamps or LED’s:-

Test is used to test the lamps or optional LED’s only by illuminating them in a steady on state for as

long as the pushbutton is pressed.

System Test is used to simulate a full functional test therefore all windows and horn circuits will

operate in accordance with the selected sequence and additional pushbuttons will need to be pressed to step through the sequence and return the unit to its normal state.

Mute is used to silence the audible but allow the associated alarm window to continue to operate

as per the selected sequence.

Acknowledge will silence the audible alarm and change the state of the associated window in

accordance with the selected sequence.

Reset will return the alarm to the normal off state only if the unit has been acknowledged and the

associated alarm contact has returned to its normal non-alarm state.

First Reset is used after acknowledge to reset the flash sequence on the first alarm to occur

within a defined group of alarms. Once f irst reset has been pressed the next alarm to occur within the group will flash at the first-up alarm rate.

8.2 Audible Alarm Grouping

Each channel within the annunciator can be set to operate the audible alarm relays as follows:-

1. Critical horn relay

2. Non critical horn relay

3. Both the critical and non critical horn relay

4. Neither of the horn relays (Typically status only alarms)

Please note channels, which are set to operate the critical horn relay, will automatically operate the internal piezo buzzer.

8.3 Ringback Audible

When using ISA “R” ringback sequence the MULT relay can be set to operate as a ringback audible if required. The ringback audible would normally have a distinct tone to allow the operator to distinguish between a standard alarm and an channel that has returned to normal and needs to be reset.

Page 29

RTK Series 725 Annunciator

9. Additional Features

9.1 Automatic Reset

Once an alarm has been acknowledged and its input has returned to its normal state the alarm can be set to automatically reset without the operator having to press the reset pushbutton.

9.2 Non-Latch Sequence (No Lock-In)

Alarms can be set to non lock-in, which allows the alarm to automatically return to the non alarm ( off ) state as soon as the signal input returns to normal.

9.3 Reflash Feature

Input reflash is used to inform the operator that an acknowledged alarm has returned to normal and re-alarmed whilst waiting for reset.

9.4 Ringback Sequence

Ringback sequence is used to inform the operator, both visually and audibly, that an alarm condition has cleared and the channel can be reset to its normal off state. When a contact returns to normal the associated window will flash at approx ½ the speed of a normal alarm and the audible alarm will sound. This identifies the specific alarm and allows the operator to reset as soon as the process is normal. As an option the MULT relay can be used to drive a 2nd audible set to a different tone to the main audible for use as a ringback audible. Please note ringback cannot function if a channel is set to auto- reset or non lock- in.

9.5 Two Pushbutton Operation

In certain circumstances using remote pushbuttons, it may be desirable to use only two pushbuttons: reset and lamp test. The reset pushbutton is used to acknowledge an alarm if the contacts are in the alarm condition and to reset it if the contacts are clear.

9.6 First-Up Sequences

When monitoring devices with interlinked functions such as a turbine or compressor it is often important to know the specific alarm that occurred first, as it will invariably result in cascade of secondary alarms. This allows the operator to focus on the root cause of failure and therefore limits the downtime and associated costs. This is achieved by having the first-up alarm flashing in a different manner compared to the subsequent alarms. Four different first-up sequences are available F0, F1, F2 and F3 as detailed below and in the following sequence tables.

F0 The standard mode adopted by RTK Instruments, which indicates the first-up alarm by flashing at

twice the rate of subsequent alarms.

F1 In this mode subsequent alarms appear in the acknowledged state, hence they do not flash. The

audible device does not operate when subsequent alarms occur, unless still operating from the first alarm. The acknowledge pushbutton will reset the first-up indication.

F2 In this mode all subsequent alarms do not flash, they will however operate the audible device.

The acknowledge pushbutton will reset the first-up indication.

F3 In this mode initial alarms appear with an intermittent flash rate and subsequent alarms flash at a

steady rate. On acknowledge subsequent alarms revert to the steady on state and only the first alarm continues to flash at a slower rate.

Please note auto reset and non lock- in functions are not recommended when using first up sequences as the true sequence of events cannot be guaranteed.

10. Sequence Configuration and Tables

Each pair of alarm channels can be configured to suit the operating sequence required, as listed in the ISA publication "Annunciator sequences and specifications" S18.1 1979.(R2004). Systems can be configured with different features on each individual channel and there is no need to switch the power off when making these changes. Different operating modes can be selected using the integral Pushbutton/Programming module as described later in this manual. The following tables show the most commonly used examples.

11. Options

11.1 General

The standard 725 Series alarm annunciator is designed to meet the majority of alarm specifications but in certain applications additional options may be required. Please note:- The following options are usually specified at the time of ordering. Please consult factory if you would like to check suitability of adding options to existing units.

11.2 LED Assemblies (Option LED)

Fit and forget LED assemblies, which plug into the same lamp socket as conventional filament lamps, are available in the following colours Red, Amber, Yellow, White, Blue or Green. Please note all alarm cards are equipped with dual function output drives allowing the standard card to be used with either conventional filament lamps or LED’s. Switch SW1-8 on each card is used to select the output drive characteristics.

FUNCTION SW1-8 Outputs suitable for driving lamps ON Outputs suitable for driving LED’s OFF

11.3 Tropicalisation (Option TRO)

In harsh environmental conditions all of the associated cards are sprayed with a conformal coating and sealed relays are used as required.

11.4 Individual Channel Repeat Relays (Option RLY)

As an option each dual channel alarm card within the annunciator can be supplied with two relays to allow a repeat signal from each channel to be sent to third party devices as required. The non alarm coil state of each relay can be set to be either:-

FEATURE FUNCTION SETTING Normally energised F2 OFF Normally de-energised F2 ON

The operation mode of each relay can be selected to be either:Input Follower

The individual relay will activate when an alarm occurs and automatically return to normal when the signal input returns to the normal state.

FEATURE FUNCTION SETTING Input follower

F18 OFF F19 ON

Logic Follower The individual relay will activate when an alarm occurs and only return to normal when the signal input has returned to the normal state and the logic has reset, this may require the operator to press the associated pushbuttons to reset the alarm depending on the sequence selected.

FEATURE FUNCTION SETTING Logic follower

F18 ON F19 OFF

Page 41

RTK Series 725 Annunciator

Display Follower The individual relay will activate when an alarm occurs and faithfully mimic the state of the output drive to the associated lamp (flashing, on or off)

FEATURE FUNCTION SETTING Display follower

F18 ON F19 ON

11.5 Individual Channel Dual Repeat Relays (Option RL2)

In applications that require two repeat relay outputs for each channel a dual channel alarm card complete with repeat relays and a dual channel relay card are required. The dual channel relay card l provides the additional set of volt-free changeover contacts. Please note:- As this feature requires additional card slots it is only available on systems using medium or large windows.

11.6 Customer Specified Response Time (Option CRT**)

The response time for standard units is factory set at 25ms. If alternative response times are required, option CRT is used to specify a fixed response time, between 1ms and 2 seconds.

11.7 Adjustable Response Time (Option AD*)

If specified at the time of order each channel can be supplied with a trim pot that allows the user to adjust the response time between two set points as required. AD1 = 5ms to 50ms, AD2 = 25ms to 2 seconds or AD3 = 5ms to 5 seconds

Please note: When setting activation delays it is important to note that the same delay will apply to the return to normal state, for example:- If a channel is set for 5 Seconds delay the input contact must be in the abnormal state for a minimum of 5 Seconds before the alarm activates. Once the input contact has returned to normal the channel will not recognise the return to normal state for a minimum of 5 Seconds and therefore the channel cannot be reset until this delay has elapsed.

On P725 annunciators supplied after March 2009 each channel is equipped with a switch, (SW2), which allows the user to select

 Return to normal state should have the same delay as the alarm activation or  Return to normal state as soon as the input returns to normal.

When using AD* options the user must use SW2 to set the normally open or normally closed input state as detailed later in the manual. Function F1 should be set to OFF when using SW2 as described in Section 24 of this manual.

11.8 Disable Integral Horn (Option DHN)

All units are supplied with an integral piezo audible as standard, which follows the critical audible group (HNA). If remote audibles only connected to the integral horn relays are required the unit can be supplied with the horn disabled.

11.9 Higher Field Contact Voltages (Option FCxx)

Standard 725 annunciators are able to accept powered signal inputs @ 24VAC/DC and as an option the unit can be supplied suitable for direct connection to powered inputs

OPTION CODE VOLTAGE

FC048 48VAC / DC FC125 125VAC / DC FC250 250VAC / DC

Page 42

RTK Series 725 Annunciator

11.10 Supply Input/Output Module (Option SI/O)

The SI/O module is required in the following instances: -

1. In larger systems to distribute the 24VDC logic supply load evenly

2. To interlink multiple annunciator cabinets together to form larger systems

3. Where the pushbutton/programming module is fitted remote from the unit

This module is fitted within a standard cell but does not use a card slot so it does not affect the number of alarm channels available.

11.11 RS485 Serial Communications (Option COM) Part No. CB4468POP1

All series 725 annunciators can be fitted with the optional ser ial communications card, which is usually located in the cell directly above the pushbutton module. This card provides RS485 bidirectional communication to and from third party devices using modbus ASCII or modbus RTU protocols as standard. All pushbutton controls can be local to the annunciator or driven remotely via the communications link. Up to 64 annunciators can be multi-dropped on the same communications connection.

11.12 Individual Channel Repeat Relays Powered By The Field Contact Voltage (Option RAV)

Option RAV is used in safety critical applications to power the individual channel repeat relays using the field contact supply voltage. In this mode even if the annunciator logic supply is lost the repeat relay facility will continue to function as normal. Please note:- The repeat relay can only function as a signal follower when option RAV is used.

11.13 Three Horn Relay Outputs (Option 3HN)

Option 3HN provides three horn relays, (HNA, HNB, GPB), and one common alarm relay (GPA) instead of two horn and two group relays. Channels are programmed to operate any of the relays using function codes, F23 = HNA, F24 = HNB, F22 = GPB, (F21 = GPA).

11.14 Three Group Relay Outputs (Option 3GP)

Option 3GP provides three group relays, (GPA, GPB, HNB), and one horn relay (HNA) instead of the two horn and two group relays. Channels are programmed to operate any of the relays using function codes, F21 = GPA, F22 = GPB & F24 = HNB, (F23 = HNA).

Please note:- The HNB relay is not equipped with a reflash function.

11.15 Repeat Pushbutton Output (Option RPB)

Option RPB provides two independent volt-free contact outputs, which follow the operation of a chosen pushbutton. A two channel relay card is added to the system and switches on the card are used to set the function of each relay to follow either:- System test, lamp test, silence, ack, reset or first reset.

Page 43

RTK Series 725 Annunciator

11.16 Group Relays Follow Inputs (Option GFI)

Option GFI allows the GPA and GPB group relays to follow the function of the alarm contact. If an alarm occurs within the group the relay will change state and will remain in the alarm condition until the associated input has returned to normal. If multiple inputs within the group are in the alarm state all inputs must return to normal before the group relay automatically returns to normal. Individual channels can be assigned to the GPA and GPB relays, (function F21 & F22), in the normal way and the optional reflash function, (Function F8 & F9), can be enabled as required.

11.17 Additional Group Relay Contact (Options 2GA or 2GB)

Option 2GA or 2GB is used in applications where a second isolated contact is required to work as a slave of either the GPA or GPB relay, (Function F21 & F22), The multi function relay (MUL) located in the SPR module is used to provide the additional contact.

11.18 Total Group Relay (Option RTG)

Option RTG is used in applications that require two common alarm groups, (GPA and GPB), PLUS a total group relay. The multi function relay (MUL) located in the SPR module is used to provide the total group relay contact, which automatically operates if either the GPA or GPB relay are activated.

11.19 SPR Module (Supply-Pushbuttons-Relay Module)

All Series 725 annunciators are equipped with 24VDC Logic. If external AC/DC or DC/DC Power supplies are required they should be capable of handling the maximum surge current, which is typically twice the maximum load when all lamps are on steady.

11.20 Logic Power Connections

In standard applications a power supply with a single 24VDC output can be wired to the 24VDC logic power by connecting to terminals 0V and +V on the rear of the SPR Module.

11.21 Signal Supply Voltage Connections

In standard applications the logic supply terminals OV and +V can be cross-linked to the signal supply input terminals OVC and +VC on the SPR module to provide +24VDC to distribute to the associated field contacts. (OV links to OVC and +V links to +VC)

The 725 Series Alarm Annunciator is always supplied with a comprehensive range of pre-defined options which can be enabled or disabled on a channel by channel basis using the integral, (or as an option remote), pushbutton / programming module. To simplify the configuration process each option has been allocated a unique “Function No.” between 1 and 24, any combination of these functions can be selected for each alarm way but care must be taken to ensure the operating modes selected do not conflict with each other. For example if ringback alarm sequence R is required the system should also be set to manual reset for the sequence to operate correctly. The key for functions 1 to 24 is shown later in the manual.

20.1 Programming Mode

The programme function of the unit is accessed by hinging down the pushbutton / programming module using a small terminal screwdriver in the recess in the top of the bezel and levering forward the top edge of the assembly. This allows the assembly to hinge down to reveal the programming information plate. To programme the unit, first place it in the configuration mode by moving the yellow switch to the “CONF” position, the "function" display will indicate 0 to confirm that the unit can be set.

20.2 Changing A Function Setting

When the pushbutton / programming module has been hinged down and the “CONF”, “programme mode”, switch has been placed to the ON position the operation of the pushbuttons changes as indicated on the information plate on the underside of the unit as detailed below:-

STATUS

CHANNEL ST ATUS FUNCTION

STATUS

STATUSCHANNEL FUNCTION

CONF

Once the unit is in the (CONF), programme mode, the window associated with the channel selected for programming will fast flash.

1. The lamp test / system test pushbuttons are used to select the required channel

2. The reset / first reset pushbuttons are used to select the required Function No.

3. The ack / mute pushbuttons are used to enable or disable the feature.

Note:- If the status LED is on the feature has been enabled.

Important note:-

If the user programmes a channel as detailed above and simply returns the unit to the run mode by placing the CONF switch to the off position the information will not be stored. Programme changes are only stored after the user has moved onto an adjacent channel, using the system test or lamp test pushbuttons, at that point the programmed information is stored in EEPROM on the associated alarm card

RTK Series 725 Annunciator

20.3 Programming Example

Example:- If channel 7 is currently set to manual reset but the user would like to change this to allow the window to automatically reset, (after acknowledge), the following procedure should be followed.

1. First hinge down the pushbutton module to access the programming plate.

2. Place the unit into (CONF), programming mode, using the yellow switch to the left of the display

3. Use first reset / reset pushbuttons to select function 3 (reset function)

4. Use the system test / lamp test pushbuttons to select channel 7 and note the associated window will fast flash.

5. Use the mute / ack pushbuttons to enable function F3 which is confirmed when the status LED is on.

6. Scroll to the next channel up or down to store the required setting using the system test / lamp test pushbuttons.

7. Return to normal operation by placing the CONF switch to the off state

20.4 Checking Programmed Settings

After all of the required functions have been set on the unit it is recommended that the user checks the configuration to avoid problems during the commissioning stage. This is a simple process that should only take a few minutes and is achieved by placing the unit into the “CONF” mode and scrolling through each channel noting that as each Function is selected the status LED is on if enabled or off if disabled. When functions such as F23 (Critical horn group HNA) are selected all windows selected to operate the relay are illuminated in a steady on state to help the user identify which alarms are within the horn group. Please note:- A window selected for programming automatically fast flashes therefore the window of the channel that is being programmed cannot be viewed to determine status information. The status LED on the information plate can be used as an alternative to view the setting for this channel, if the status LED is on the function has been enabled, or the user can move to an adjacent channel to allow the alarm window to be used in the normal way.

20.5 Systems With Unarmed Ways

Each dual alarm card in the system is provided with a unique binary address, which is set using on board DIL switches during manufacturing. If the system has been supplied with unarmed ways the address normally used for the associated channels will be reserved to allow the user to add the card at a later date. The programming module is designed to stop navigating between channels when it detects a missing card address (normally the last card in the system). When the channel navigation stops because of unarmed ways it is necessary to “jump over” the missing address to access any further channels. To “jump” an address the user needs to hold down the reset pushbutton and then press and hold the "channel up or down" pushbutton.

20.6 Points To Note When Programming

Alarm channels are always numbered in a standard format depending on window size and the channel up / down pushbuttons are used to automatically move between each channel in the correct order. The selected feature is only stored when the user selects an adjacent channel (either going up or down). After the programming is complete it is recommended that the user checks the required functions have been enabled correctly. After programming it is recommended that any channels that have been changed are tested to ensure that the operation is in line with the required functions. The programming process includes an inbuilt comprehensive error checking routine. In applications where there is extreme electrical noise this may result in the program not being accepted. If this happens, simply repeat the process for that particular alarm channel.

To access the individual alarm card the plastic cover plate on the rear of the associated cell must be removed by squeezing the lock-in tabs on either side of the cover.

The alarm card can then be removed to allow adjustments to be made to VR1 (Channel 1) and VR2 (Channel 2) as required.

The standard adjustment is in the range 5ms to 50ms turning the trim pot in a clockwise direction to increase the response time.

Return to Normal Delay Period

In standard applications any delay period set for alarm initiation is also applied to the return to normal state.

For example if a 5 second delay is set, the alarm will not activate until the input has been in the abnormal state for a minimum of 5 seconds.

If the alarm returns to normal the same delay period of 5 seconds will apply before the alarm state returns to normal.

In some applications Customers prefer the alarm to have a delay before the alarm activates but as soon as the input returns to normal they require the alarm to return to the non alarm condition.

25. Systems with Serial Communication

Introduction

As an option the annunciator can be supplied with an internal serial communications card which is switch selectable to use modbus ASCII or modbus RTU protocol . This allows the annunciator to interface to 3rd party devices such as PLC's, DCS, industrial computers, SCADA packages etc. The annunciator is RS485 / RS422 compatible and can easily be co nverted to RS232 using a suitable external converter. As standard the annunciator acts as a 'slave' device, but can be configured to act as master when communicating to slave P725 annunciators.

Bi-Directional Communications

The bi-directional communications card allows the unit to read and write data to each alarm window, which provides contact status, window illumination control/status, and pushbutton information. Each channel within the annunciator can be set to alarm from a hard wired signal input or via the serial communications as required.

Configuration

The baud rate, parity and protocol are selected by changing DIL switch settings on the communications card as described later in this section.

Address Selection

Each annunciator is set with a unique address from 0 to 63, which allows up to 64 separate annunciators to be connected in a single RS485 multi-drop loop. RTK can also supply comprehensive alarm monitoring and logging software if required.

Character Format

ASCII 7 data, 1 start, 1 stop, 1 parity RTU 8 data, 1 start, 1 stop, 1 parity

Message Format

In accordance with the standard modbus protocols, all data exchanges are assumed to comply strictly with these standards. ASCII transmissions will start with a colon and end with longitudinal redundancy check (LRC), carriage return and line feed. RTU transmissions will not use framing characters and will incorporate a cyclic redundancy check (CRC). For further details please refer to the "Modicon modbus protocol reference guide” available from Modbus-IDA www.modbus.org

Fault Indication

If communications cannot be established within a specified time-out period (typically 10 seconds) then the watchdog relay on the communications card will trip and, if fitted, the "communications fault" window will illuminate. This indicates there is a communications fault either with the external device or with the integral alarm cards within the annunciator. Because the system continually attempts to regain communications it will self-recover as soon as communication is re-established.

Page 78

RTK Series 725 Annunciator

P725 to P725 Connections

For applications where local and remote annunciators are required two or more P725 annunciators can be interconnected. In the normal situation one of the annunciators will monitor the standard voltfree alarm contacts or voltage inputs and indicate the alarms as normal. This alarm information is then transmitted on the serial communications to another P725 annunciator using either two or four wires for the communications. These systems are interconnected as shown later in this section.

System 9000TS To P725 Annunciator

The System9000TS Annunciator from RTK Instruments can also be used as described above to monitor a number of alarm contacts and transmit the information via the serial communications to a remote P725 annunciator. The System9000TS can optionally have a display to indicate alarm information or simply operate as a data gathering and transmission device. Please refer to our sales office for further information on these systems.

Modbus Communications

Full details on how to use modbus ASCII and modbus RTU protocols are not given within this manual as they are well covered by more specialised manuals. A brief overview of the main features is shown below.

Modbus Function Codes

The function code field tells the addressed 'slaves' what function to perform. The only relevant function codes when communicating to the P725 annunciator are as follows:-

03 Read register This reads 16 bit data registers containing alarm information 06 Write register Writes data to 16 bit register. This data request can be used

as an alternative alarm input source.

Error Check

The error check is either LRC (Longitudinal redundancy check) or CRC (Cyclic redundancy check) depending on whether ASCII or RTU modbus is selected.

Software

RTK Instruments can supply comprehensive monitoring software for use with the 725 Series alarm annunciator. This can be configured as an alarm/event management system with user generated custom displays to monitor plant wide system operation.

Serial Interface Card Address selection

Each annunciator needs to have a node address selected which must be between 0 and 63. It is this address that makes the annunciator unique and allows the external equipment to communicate to a defined annunciator within a multi-drop system. The following examples are provided as a guide to setting the address

Enable Remote Serial Pushbutton Control

In systems connected to a remote device via the communications link it is sometimes a requirement for the pushbutton control to be provided externally via the communications port.SW1-7 should be set to the ON position in applications which require a slave P725 to mimic the functions of a master unit. The local pushbutton will remain operational even if this feature is enabled.

Lamp or LED Outputs

SW1-8 should be set to the ON position in applications using filament lamps to display the serial communication watchdog alarm within the annunciator (typically located above the integral pushbutton module).

SW1-8 should be set to the OFF position in applications using “fit & forget” LED assemblies in place of filament lamps.

SW2 Selection

The table below indicates additional communication parameters that can be set by the user.

SW2-* FUNCTION ON OFF SW2-1 Set communication baud rate 4800 9600 SW2-2 Set Modbus protocol type RTU ASCII SW2-3 Set parity type ODD EVEN SW2-4 Set as Modbus master or slave Master Slave

All switches are factory set to off as default so it is only necessary to make changes if the standard parameters do not suit the particular configuration.

The master/slave selection is only used when a P725 annunciator is using the serial communication link to communicate to another P725 annunciator in a master / slave configuration as detailed earlier.

Option MOD C7 High Speed Communication Version

As an option the Communication port can be supplied as a high speed version with the following selectable speeds.

Data

The data field uses 16 bits. The information it contains is dependent on the type of data interchange being performed i.e. read or write, register address, status of functions 16, 17 and the status of SW1 Position 7 on the communications board. The table below lists the main types of data interchange and the various settings required. It is assumed in the table below that remote data originates from a master, and local data from a P725 slave.

Channel Data

The following table shows the name, function, and relative position of data bits in the data field for a read response or write request of alarm channel data.

BIT DATA

LOWEST WORD 0 Input state

1 First up 2 Acknowledge 3 Input latch 4 Ringback 5 Not used 6 Not used 7 Not used

HIGHEST WORD Not Used

Channel data request register address 0 - 255

Input State-BIT 0

0 = Normal, 1 = Abnormal Read response + F16 deselected – Indicates status of local alarm contact Read response + F16 selected – Indicates status of input bit

If the alarm contact is in the alarm state then this bit will be one. This has no relation to the actual contact being open or closed which is set using the function number F1, it simply states that the contact is in the alarm state.

First-Up-BIT 1

If this bit is set to one then this channel is a first-up alarm. If multiple first-up groups are used it will be possible to have multiple first-up alarms. The serial communications transmits no details on alarm grouping so this would need to be done externally if required.

Acknowledged-BIT 2

When an alarm channel is acknowledged the visual and audible states are normally changed. When this bit is set to one it indicates that the alarm channel has been acknowledged.

Input Latch-BIT 3

Each alarm channel has in integral latch that is normally set when an alarm occurs and does not reset until the alarm is acknowledged and also reset. This bit will indicate that this latch is on when set to one which means there is still an alarm present that has not been acknowledged and reset.

Ringback-BIT 4

With this sequence set further indication will show that the alarm channel has returned to normal and can be reset. If this bit is set to one then the channel is in ringback mode.

Page 85

Read of multiple channels

 In applications where you need to read or write the status of the input channel without any

information on the full alarm status it is possible to transmit 16 channels in a single read/write cycle. This information can be read (Modbus Function 3) or written to (Modbus Function 6) and starts at address 2000 for channels 1 to 16 (bit 0 = channel 1, bit 15 = channel 16), address 2001 for channels 17 to 32 (bit 0 = channel 17, bit 15 = channel 32) and so on.

 On Systems supplied after May 1st 2006 the user is also able to read or write the latch state

of the input channel and transmit 16 channels in a single read/write cycle. This information can be read (Modbus Function 3) or written to (Modbus Function 6) and has a starting address of 2016 for channels 1 to 16 (b it 0 = channel 1, bit 15 = channel 16), address 2017 for channels 17 to 32 (bit 0 = channel 17, bit 15 = channel 32) and so on.

28. Systems Linked To 3rd Party Devices

General

Using the advanced communications facilities on the series 725 annunciator, it is possible to c onnect the unit to a variety of 3rd party devices to monitor or control the alarm annunciator.

Any 3rd party device equipped with either a RS485 or a RS232 port using modbus protocol can be connected to the P725 annunciator.

Please note:-

If the RS232 port of the 3rd party device is used a RS485 / 232 converter will be required. The P725 annunciator always operates as a slave device and it is therefore only able to read and

write following requests from the master device. Various parameters of the communications are user configurable using DIL switches on the

communications card. In larger applications up to 63 separate annunciators can be connected to a single communication

network to allow remote monitoring by 3rd party equipment. In addition to the annunciation RTK can also supply suitable alarm management software pre-

installed onto a single computer or as part of a complete plant wide alarm management system.

29. P725 To P725 Serial Links

Local And Remote Systems Linked Via Communications

In applications that require local panel alarms to be duplicated or summarised in a central control room each P725 can be supplied with a serial interface card which allows RS485 communication between units using Modbus protocol.

As an example a local annunciator can be hard wired to the alarm contacts and the alarm information can be transmitted over the RS485 communications link to a slave P725 unit mounted in a control room or monitoring station.

RS485 LINK BETWEEN P725 ANNUNCIATORS

SLAVEMASTER

Each Serial Communication card is equipped with a watchdog relay and this relay will change state if any errors in the internal or external communication are detected.

In larger applications multiple P725 Annunciators can be connected to a single P725 Annunciator used for central monitoring. Each annunciator in the scheme will require the optional serial interface card.

The key advantage with units configured in this manner is the central monitoring annunciator only requires 24VDC logic power and a 4 core RS485 cable to function.

In this example functions F16 and F17 are used to configure each unit to either transmit or receive serial data as required.

Please note:- one of the devices must be set as a master.

30. Commissioning

A qualified technician properly trained and authorised to work with this type of equipment should carry out commissioning and servicing operations. The following procedure is a summary of the steps normally taken when installing an alarm system. This is the absolute minimum requirement and will generally be supplemented by a number of additional checks relating to the particular application and installation.

STEP FUNCTION

1 Check all external customer connections to the annunciator are free from earth faults. 2 Ensure the annunciator has been correctly earthed using appropriate sized cable. 3 Check that all customers wiring added during installation is secure and correctly wired. 4 Apply a 24vdc logic supply and check that the power on LED illuminates correctly.

Press the system test pushbutton to check that all active alarm channels flash and the audible alarm sounds in accordance with the programmed sequence.

6 Press the remaining pushbuttons required to control the programmed sequence. 7

Refer to the section on programming and check that all of the required functions have been correctly set.

Initialise each channel one by one from the field device to check that the laser printed film legend and filter colour matches the associated process.

Page 90

RTK Series 725 Annunciator

31. Maintenance

31.1 No Special Tools

All normal maintenance and programming is carried out from the front of the annunciator without the use of special tools. Filter and film legend changes and lamp and LED replacement are all undertaken by unclipping the front filter assembly.

31.2 Removing Filter Assemblies

See Section 3.4.

31.3 Changing Film Legend

See Section 3.4.

31.4 Changing Bulbs/LED Assemblies

After removal of the filter assembly the lamp holder will be visible. A lamp test pushbutton can be pressed to ascertain which lamps have failed; it is then a simple matter to remove the faulty bulbs. These bulbs are standard 10mm glass wedge and can be removed by pulling directly away from the lamp holder with a pair of pliers or the standard lamp remover supplied with the unit. Replace by reversing the procedure, taking care that the wedge base is correctly located in the socket before pressing home. The LED assemblies are removed and replaced in exactly the same way accept that the glass wedge is replaced with a small PCB connecting tag. The LED’s are not polarised so can be fitted in either orientation.

31.5 Fuse Replacement

Two fuses protect the overall system, one protects the supply and motherboard (F1) and the other protects the feed to the alarm contacts (F2). These are both situated on the supply card, which is fitted in the SPR module. The location of the two fuses is shown below. Take care to replace fuses with fuses of exactly the same type. Spare fuses are supplied with all annunciator shipments.
