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.

GEK-83885 Mark IV SPEEDTRONIC” Gas Turbine Control Operator’s Manual
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

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
Select Alarm Display Alarm
Switch Group
Display Mode
Silence alarm horn
Acknowledge alarm
Reset alarm
Lockout an alarm
Unlock an alarm
Silence Alarm

Display Functions
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
function.

4-1. INTRODUCTION 4-2. OPERATOR INTERFACE DEVICES
The Auxiliary D isplay, located in the upper rightcorner o f the Operator Interface Module (see Figure4-l), functions as a CRT backup. It enables an opera-tor to observe key system parameters (List Mode), andto observe and acknowledge all alarms (Alarm Mode)from data selected from any one of the four controlpanelcomputers CC>, CR>, <S>, or <T>.
The Auxiliary Display co nsists o f a digital display,
computer status indicating lights, and two groups ofswitches. These devices are described below .
4-2.1. Functiou/VaIue Digital Display. This dig-
ital display has two fields:
Section 4-3 provides Auxiliary Display operating in-stuctions. These instructions are also available o n theAuxiliary Display instruction plate, normally stored inthe drawer with the panel printer. This plate has amagnetic backing for attaching it to the panel frontwhen using the Auxiliary Display.
