CHAPTER 1

OVERVIEW

GEK-83885

l-l. INTRODUCTION

This manual provides information needed by an op-erator to use a Mark IV SPEED TRON IC” controlpanel to interface w ith gas turbine equipm ent. Itdiscusse s typical control sw itches, primary displays,and log printouts associated with gas turbine opera-tion.

Cha pter 2 describes the operator control panelswitches and their functions. Chapter 3 covers the CRTdisplays available to the operator. Cha pter 4 discuss esthe auxiliary display portion of the operator interface

module, which is a backup display for the CRT.

This manual is intended to supplement the operator’sman ual w ritten for the overall gas turbine system. Itdoes not cover mainte nance displays nor specific de-tails of each installation. Main tenance personnelshould refer to the Mark IV SPEEDTRONIC” Gas

Turbine Control Maintenance Manual (GEK-83886) andthe system elementary diagrams.

l-2. O PERATOR INTERFA CE

The Operator Interface Mod ule (see Figure l-l) is thecontrol pan el device through which an operator com-municates with the gas turbine system. It is located onthe Mark IV SPEEDT RONIC control panel’s front

door.

The Operator Interface M odule contains input devices(membrane switches and an Emergency Stop pushbut-ton) used either to send comm ands to the gas turbinecontrol or to request CRT display s. It also includes aCRT, on which the operator can view all parametersrelevant to the gas turbine operation. These p arame -ters are displayable in English or metric engineering

units.

A panel-mounted printer, located below the OperatorInterface Mo dule, enables the operator to man ually

select and copy any display, and to autom atically log

selected parameters.

CHAPTER 2

OPERATOR CONTROL SWITCHES

2-1. INTRODUCTION

The Operator Interface Module (refer to Figure l-l) isused by an operator to control gas turbine equipmentor to obtain data about the equipment. It contains ninefunctional groups of switches, used as follows:

For controlling the equipment

- Operation/Control group- Emergency Stop pushbutton- Alarm group

a To manipulate data

- Display Keypad group- Display Cursor group

“- Display Mode group

- Display Functions group- Printer group

0 As an alternative to the CRT

- Auxiliary Display group

The following paragraphs describe these operator

controls and their functions.

Most operator controls function only when the < C >Communicator computer is operating. However, theEmergency Stop pushbutton (see Figure 2-l) is active inall modes of operation. Additionally, the followingswitches, identified by a blue triangle printed on them,remain functional when the < C > Communicator is

not operating:

stop in the Operation/Control group

Alarm Silence in the Alarm group

Alarm Reset in the Alarm group

OPERATION/CONTROL SWITCHES

The operator uses Operation/Control switches (seeFigure 2-l) to send control commands to the gasturbine equipment. These switches are designated bytheir yellow color. Up to 28 Operation/Control

switches reside in a group on the right side of theOperator Interface Module. This group is divided intothe functional subgroups of Operation, Load, Master

Control, Fuel, IOV Temperature Control, and optionalswitches. Another Operation/Control switch,Execute, islocated on the lower left side of the module.

The operator initiates a control command to the gas

turbine equipment by pressing the appropriate Oper-ation/Control switch. The control responds with anaudible “beep” to acknowledge receipt of the input,and flashes the light above the switch. It then waits forthe operator to confirm the command. To do this, the

operator must press the yellow Execute switchwi th in 3seconds after pressing the control switch.

** NOTE

This procedure for confirming a com-

mand input prevents false commands

from being executed. Only switches in the

Operation/Control group require the op

erator to also press theExecute switch. All

switches in the other functional groups,

plus the Emergency Stop pushbutton, do

not require this protective feature.

When the Execute command is received, the light abovethe control switch changes from flashing to continu-

ously on if the gas turbine can accept the control input.For example, the gas turbine cannot accept a Crankcommand if it has detected a fire. Also for example,when the Normal Display (see section 3-2) displays themessage NOT READY TO START, a Stirt command

input is accepted but cannot be acted on. When thisoccurs, the system displays an alarm message that

specifies the reason the start per-missives are notsatisfied.

Not all Operation/Cont.rol switches require pressingthe Execute switch. Ones that involve continuous mon-

itoring (such as the optional Raise and Lower switchesthat adjust the speed/load setpoint on compressordrive applications) do not require the execute action.Additionally, the Stop switch, which normally requires

pressing the Execute switch, functions without it if the< C > Communicator stops operating.

The following shows a typical operation selectionprocedure:

Operation Press Switch Comments

Off 1. off Off light on

Crank 1. Crank Crank light flashes

2. Execute Crank light goes onsteady, Off light goes off.

2 3. EMERGENCY STOP PUSHBUTTON

The Emergency Stop switch is a large red pushbuttonlocated on the lower right side of the Ooerator Inter-face Module (see Figu;e 2-l). The op&ator pushesEmergency Stop to stop the gas turbine under emer-gency conditions, instead of using the normal shut-

2-2

down sequence. This pushbutton mechanically latchesin the STOP position when it is pressed. As notedpreviously, Emergency Stop is active in all modes of

operation.

Function Operator A on

Emergency stop Press Emergency StopReset emergency Turn Emergency Stop clockwise

stop

2 4. AIARM SWITCHES

The two Alarm switches are located below the CRT(see Figure 2-2). The Operator uses the Alarm Silenceswitch to silence the alarm horn. The Reset switchresets all acknowledged and cleared alarms. As notedpreviously, the Alarm group switches still functions if

the < C > communicator is not operating.

Section 3-3 discusses the alarm system.

2 5. DISPLAY KEYPAD SWITCHES

An operator uses the Display Keypad switches to selectData List displays or parameters that appear on theCRT. These switches are located directly below the

CRT (see Figure 2-2). They include a full set ofalpha-numeric characters and the following auxiliary

switches:

Space - Creates a blank character

Delete - Deletes a single character

Clear - Deletes an entire character string

S&l - Accesses the alternate character printed

at the top of the Display Keypad switch when

pressed with the switch

Enter - Loads the typed characters into the

computer to initiate a command

The description of the displays (Chapter 3) provides

examples of how to use the Display Keypad switches.

2-6. DISPLAY CURSOR SWITCHES

A cursor appears on some CRT Data List displays. It is

used during maintenance to select a signal value, alogic level, or a constant to be changed, entered, ordisplayed. The operator moves the cursor by pushing

the Display Cursor switches Up, Down, Lefi, and Right.

As shown in Figure 2-2, these switches are locatedbelow the CRT.

2-7. DISPLAY MODE SWITCHES

The operator uses the five Display Mode switches(Norm&,Manual, Alarm, Manual Control, and Reset) toselect display modes. These switches are located on leftbottom side of the Operator Interface Module (see

Figure 2-2). Chapter 3 describes the CRT displays anduse of these switches.




2 8. DISPLAY FUNCTIONS SWITCHES

The six Display Functions switches (see Figure 2-3),labeled Fo thru F,, are located on the right side of theCRT . These are “soft keys” because the switch functionis assigned by the software associated with a particularCRT display (see Chap ter 3). It displays the function

on the right side of the CRT screen, adjacent to theassociated Display Functions switch.

For example, the Alarm D isplay mode assigns hmc-tions to the Display Fu nctions switche s as follows:

2 9. PRINTER SWITCHES

The two Printer switches, located below the CRT (see

Figure 2-2), are used as follows:

Function Press Switch

Printout of current CRT display COPY

Printout of historical log History

The historical log (see Figures 2-4 and 2-5) containsthe values of key gas turbine parameters, such as speedand exhaust temperatures (Parts 1 thru 5) and allalarm messages (Part FL). These parameters include:

HISAGE - History Age (Seconds)

TNH - HP Turbine Speed (% Speed)

TNR - Turbine Speed Reference (% Speed)

FSR - Fuel Stroke Reference (% FSR)

CSGV - Inlet Guide Vane Calibrated Stroke

Position (Degrees)

CI’IM - Turbine Compressor Inlet Flange

Temperature (Maximum input select) (“F or “C)

0 CPD - Turbine Compressor Discharge Pres-

sure (PSIG or BARS)

0 TTXDl,1 thru IS-- Exhaust Thermocouples

Temperatures (“F or “C)

The turbine control samples each parameter andalarm message during the ten points in time preceding

the current print request. This sampling occurs con-tinuously while the turbine is running. A turbine trip

or shutdown stops the sampling, but retains the datauntil the turbine is restarted.

2-10. AUXILIARY DISPLAY SWITCHES

The Auxiliary Display is provided as a CRT backup.

Chapter 4 describes the Auxiliary Display and itsFunction Selector and Section Selector switches.

CHAPTER 3

CRT DISPLAYS

3 1. INTRODUCTION

The Display Mode switches, shown in Figure 2-2(Normal, Manual, Alarm, Manual Control, and Reset),

allow the operator to select displays on the CRT. Thischapter describes the use of the Display Mode switchesand shows examples of the associated displays.

3 2. NORMAL DISPLAYS

The Normal Display is the primary display that theoperator “normally” watches. This display shows all ofthe key gas turbine parameters that an operator needsto observe. The operator selects this display mo de by

pressing the Normal switch.There are three Normal Displays, which indicate thegas turbine operating mode: STARTU P STA TUS,RUNNING STATUS, and SHUTDOW N STATUS.

During any of these m odes of operation, the controlsystem automa tically selects the display that applies tothat m ode. All of the displa ys are similar in format (seeFigure 3-l), but differ slightly in content. For example,

the STARTU P STATUS dismay (Figure 3-2) showswhich flame scanners have A etected flame. in thecombustion chamber. H owever, the RUN NING STA-TUS display (Figure 3-3) does not show this since theturbine must have flame if it is running. Instead, withthe RUN NING STATUS display, an alarm me ssagewarns the operator if lame is lost on any channel whilethe turbine is running .

The NOR MA L DISPLAYS include the typical display

fields, described in the following parag raphs andshown in Figure 3- 1.

3-2.1. Operating Mode. The Operating Mode

field indicates the state of the gas turbine. The m es-sage automatically changes when the mode changes.The m essage s for this field are:

the more comprehensive Alarm Display. In addition,

the number of previously acknowledged alarms is

shown.

An operator can silence, acknowledge, and reset an

alarm without changing the display. This is done by

pressing either the Alarm A& switch (F5) in the Display

Function s group, or the Silence or Reset switches in the

Alarm group.

3-2.17. SELECT (Additional Parameters). The

SELEC T field enables an operator to select three

parameters to be displayed simultaneously, without

needing to call up another display. These can be

control or logic type signals, a nd ca n be called by their

functional name used on the Gas Turbine Control

elementary diagram.

The ope rator selects signals by typing the requiredsignal name(s) on the Display Keypad switches, as

follows:

Normal Display Function Operator Action

To display signal in SELECT 1. Type signal nam e

field 2. Press Enter

To clear all SELEC T fieids l.TypeO2. Press Enter

This displays the logic or analog param eter in engi-neering units. When more than three signals areentered, the bottom signal is deleted from the displayand the new signal is added to the top of the list.

3-2.18. ALARM ACK. This display field assigns

the Alarm Acknowledge function to the Display Func-tions switch F,. Press this switch to acknowledge a

flashing alarm message.

3-2.19. IDENTITY. This field is provided for

reference on multiple un it installations , and may bedisabled on single unit installation s. This field displaysan optional two-character ASC II string for identifying

the control panel or turbine being monitored. Ma in-tenance personnel enter the ASCII string using theAdministrative Display.

3-3. ALARM DISPLAYS

The Alarm Display (see Figure 3-5) lists all gas turbinesystem alarm messages in chronological order, withthe date and time that the alarm was recorded. Thelatest alarm appears at the top of the list, with theunacknowledged alarm drop numbers flashing.

The D rop column shows the alarm’s identifying num-ber. A “ 1” in this column shows that the alarm logicsignal is in the Alarm state; a “0” shows that it’s in theNormal state.

The operator can manipulate alarms and alarm dis-

plays as follows:

Function Press Switch

Display Mode

Silence alarm horn

3. EntmDisplay KeypadDisplay Keypad

(Drop no. appears in inverse video)

1. Alarm Unloc$. gny; drop no.

Display FunctionsDisplay KeypadDisplay Keypad

(Drop no. returns to normal video)

When an alarm is acknowledged, the display changesfrom flashing to steadily on. When the operator resetsan acknowledged or cleared alarm, the system deletesit. Table 3-l show s a typical alarm sequence.

3-3.1. Alarm Lockout. Sometimes an oscillating

alarm condition causes the alarm cond ition to repeti-tively set (alarm) an d reset (normal). An “alarm lock-out” feature enables the operator to prevent thesystem from continuously logging the event.

Locking out the alarm latches it in its current condi-tion. The latched alarm drop number appears ininverse video to remind the operator that the alarm islocked o ut. The drop number then remains in inversevideo until the operator unlocks the alarm.

3-3.2. Alarm Logging. For automatic alarm log-

ging, the panel moun ted printer prints the appropri-

ate alarm message each time the corresponding alarm

logic signal changes status. It notes the status (alarm ornormal) of the alarm logic signal.

The alarm log format is: date, time, drop number,

alarm m essage, and status (Alarm or Normal).

3-3.3. Diagnostic Alarms. Another group of alarm

messages are the diagnostic alarms. Maintenance per-sonnel use these to determine the nature of a faultcondition within the control panel. This condition isidentified by the alarm message DIAGN OSTICALA Rh4 - SEE DISPLAY . The Diagnostic Alarm dis-

play can be accessed by pressing the Diagn Alarmswitch in the Display Functions group.

3-5.6. Data List 12: Demand Display. This datalist enables the user to display up to 64 selected datapoints or signal names on two pages of the CRTdisplay. Figure 3-13 shows the normal Demand Dis-play. (“ Normal” is when the Dem and Display is not in

a Set Mode.) Each item in the list consists of the Nam e,Value, and Units (for example, TTXM, 821, DEG F).

This data list can be printed on the panel printereither by ma nual initiation or automa tically. A man ualcopy prints only the page c urrently displayed on theCRT.

An automa tic log periodically prints all the pages ofthe data list with the header message “ Demand DisplayLog.” While the automa tic log mode is selected, thedata list is printed after each expiration of the speci-fied time interval. The tim e interval may be set fromcontinuous operation up to 24 hours.

Figure 3-14 shows the reassignment of the DisplayFunctions switches during the Set Time m ode.

3-4.7. Data List 13: Rung Display. The Rung

Display presents the control Sequencing data in aladder diagram format. This display provides a conve-nient method of reviewing the sequencing data, andthe current status of each compon ent. Maintenancepersonnel use this display for troubleshooting, but

operators can use it to review the condition of specificfunctions.

The Display Functions switches are used to changedisplays, find a rung by signal n ame, find rungs thatuse a particular signal name, and to switch between R,S, T, and C sequencing. Each screen displays one rung.Figure 3-15 shows a typical rung display.

The system provides two methods to indicate the

current value of each contact and coil in the ladderdiagram. The CRT uses inverse video to indicatecontinuity thru a contact and to indicate that a coil isenergized. However, since printed copy cannot usethis method, it places a “-” under each closed contact

and energized coil.For reference, the display also includes the currentvalue of variables used in special fu nctions, such astimers. These special functions are shown enclosed ina box. Refer to Figure 3- 16 for an example of a timer
