C. MASTER/SLAVE BOILERS OPERATION

(a ) MASTER/SLAVE BOILER OUTLINE OPERATING PRINCIPLEThe master boiler operates singly or in coibination with the slaveboiler, with the slave unit started and stopped automaticallydepending on the master boiler load: as the master boiler loadexceeds 60X the slave boiler automatically starts operating fordual steam generation; as the master boiler load goes down tobelow 2Q& the slave unit automatically stops its operation leavingthe master boiler alone in service.

(b ) MASTER BOILER FUNCTIONS(1) Selection of master boiler

Either boiler may be selected as the master unit if itsinterlock system is in the normal setting (no trip), bydepressing the designated "MASTER" push button.

(2) Change to steai drum set pressureThe master boiler drum pressure setting can be changed by themaster boiler manual adjuster alone. And the slave boilerdrum pressure setting will be kept t® the same level as thatof the master unit.

(3) Master Boiler automatic start/stopwith the master boiler burner in the "AUTO" mode, the masterboiler A. C. C. signal (S.D. press. ) cause the burner to automaticallystart and stop firing (B— [ D ] — C to be referred to).

Automatic startThe master boiler automatically starts up as the S. D. pressurereaches 12 Kg/cm2.

Automatic stopThe master boiler automatically stops operating as the S. D.pressure reaches 16. 3 Kg/cm2.

SAMPAGE 12

/if

(4) Slave boiler autoiatic start/stop

Once the master/slave boilers operation is established, theslave unit is automatically started and stopped according to

the change in master boiler load ( B - [ I ] - C (c) to bereferred to) .

AutomaticstartAs the master boiler load increases and F. 0. pressure

reaches 10 Kg/ci2 (60X load), the slave boiler automaticallystart its operation

Autoiatic stop

As the master boiler load decreases and the P.O. pressure gose

down to 4.0 Kg/cm2 (20& load), the slave boiler automaticallystop its operation

NOTE :Even when the slave-boiler burner was manually ignited and thesteam pressure reached the setfpoint,thereafter thereby placingthe slave boiler in the "AUTO RUN" mode and then only when theslave-boiler burner "AUTO" is selected, the slave boiler doesnot stop automatically unless the slave boiler steam pressurereaches 16.3 Kg/cm2 even if the master boiler's load goes downunder 20&

SAMPAGE 13

(c ) SLAVE BOILER FUNCTIONS

The slave boiler fuctions may be classified as follows by the

state of the "SLAVE" lamp.

(1) "SLAVE" Lamp off#The slave boiler is not in the "AUTO" lode (A. C. C. andburner "AUTO")

*The slave boiler is operated by its own A. C. C. signal (S. D.press. ). Iith the "BURNER AUTO" node, the burner automaticallystarts and stops firing controlled by the A. C. C. signal, asfollows.Automatic startThe burner automatically starts firing as the S.D. pressurereaches 12 Kg/cn2

Automatic stopThe burner automatically stops firing as the S.D, pressurereaches 16. 3 Kg/cm2.

(2) "SLAVE" Lamp flickering*The slave boiler is in the "AUTO" mode (A. C. C. and burner "AUTO"),fhereas the master boiler is not in the "AUTO" mode(A.C.C.and burner "AUTO").

*The slave boiler is operated by its own A. C. C. signal (S. D.PRESS. ). Iith the "BURNER AUTO" mode, the burner automaticallystarts and stops firing as per ( [ I ] — C(c)(l))

(3) "SLAVE" lamp on*The condition ( [ I ] - C(d)(D) for master/slave boilersoperation has been established.

The slave boiler is automatically started and stopped(automatic steaming operation *1) by its own A.C. C. signal(S. D. press. ) and also automatically started and stopped(loading operation *2) by the master boiler A. C. C. signal.

Automatic startthen the slave boiler S. D, pressure has reached 13 Kg/cm2 orwhen the master boiler F.0.pressure has reached 10 Kg/cm2.

Automatic stopthen the slave boiler S. D. pressure has reached to.master setpressure or when the master boiler F. 0. pressure has gone downto 4. 0 Kg/cm2 and below.

SAMPAGE 14

( d ) MASTER/SLAVE BOILER OPERATION

laster/slave boiler operation1) then both the master and slave boilers have gone into the

"AUTO" operation while in the A. C. C. (P.O.) and"BURNER AUTO" mode ( [ I ] - C (d)(2) to be referred to)

The laster/slave boilers operation is initiated when either 1)above is established.

(2) Master/slave boilers operation in TANKER SERVICE modeIn the laster/slave boilers operation, the two boilers areoperated in parallel by the laster boiler A. C. C. signal.

(3) Master/slave boilers operation in IGS lode.In the IGS lode, the burner switches to the "MAN" lode anddoes not perform automatic start/stop operations.fith both the master and slave boilers in automatic running,they are controlled for parallel operation by the masterboiler A. C. C. signal.Also, 3GX load limit is applied to both boilers and the minimumcombustion rate is limited tto 3Q5K of rated boiler load.

Notes : *1) "automatic steaming operation" - operation to maintainthe slave boiler to be stand-by condition by automaticstart at 12 Kg/cm2 and stop at master set press.

*2) "loading operation" - operation to supply steam to the plant.

D, OPERATION PANEL GRAPHIC FLOW CHART

This is an operation panel fitted on "B/S BOILER CONTROL PANEL".

"BOILER" mode and "F.O.TEMP BY-PASS" switch, which are commonly operated,

can be found on "STBD" Boiler Operation Panel.

The operations (A-l ~~ B-6) described below show how to start and stop the

boiler by way of "BNR ON" / "BNR OFF" switch, when the boiler is in the

conditions 1 ~ 7 specified as follows.

1. It is Master Boiler.

2. Boiler is in "TANKER SERVICE" mode.

3. Burner is in "MAN" mode.

4. Each station of ACC is in "AUTO" mode.

5. F. D. fan is in "AUTO" mode.

6. F. 0. pump is in "AUTO" mode.

7. Boiler is in normal condition (not in alarm condition).

* If the burner is in "AUTO" mode, tlie boiler is started and stopped

automatically based on the boiler load. Thus, it is unnecessary to

operate "BNR ON" and "BNR OFF" switch. SAMPAGE 27

1 . AUTOMATIC COMBUSTION CONTROLIn this system, the fuel oil injection, and the coibustion air quantityfor injection of fuel oil required for coibustion are controlled atoptiiui in order to maintain steam pressure to a given point for therequired steam flow rate.The control loops and functions of the A. C. C. are detailed below.

(1) MASTER CONTROL(a) MASTER CONTROL LOOP

This loop detects the steal drum pressure (master press.). comparesthis pressure with a preset pressure (master set press.). performsthe "PiI" operation, and outputs the F. 0. flow control signal (mastersignal) so as to set the deviation to *0".Also, the master control comprises the following sub-loops.

(b) F. 0.FLO! CASCADE CONTROL SUB-LOOPThe fuel oil flow control signal (Master Signal) and the oilpressure before the burner are compared with the signal (feedback) converted to fuel oil flow rate. "P-fl" operation isperformed, and the operating signal to F. 0. Cont. V. iscontrolled so as to set the deviation to zero.

(c) HOT START & STEAMING UP CONTROL SUB-LOOPThe Master Set Press, is controlled so as to obtain press, rise rate,

from steam drum press, of 5kg/cm2 to normal press. (16kg/cm2).

(d) BURNER ON-OFF CONTROL SUB-LOOPSteam drum press. (Master Press. ) is detected, and the burner isautomatically ignited and shut-down. The set points for ignitionand shout-down are automatically selected by Boiler Mode.

2-2-6 Memory Cassettes

C200HS-ME16K (EEPROM)

The C200HS comes equipped with a built-in RAM for the user's program, so anormal program be created even without installing a Memory Cassette. An op-tional Memory Cassette, however, can provide greater speed and flexibility.There are two types of Memory Cassette available, each with a capacity of 16Kwords. For instructions on installing Memory Cassettes, refer to Section 3 Instal-lation.The following table shows the Memory Cassettes which can be used with theC200HS PCs. These Memory Cassettes cannot be used in C200H PCs.

The ROM chip is not included withthe Memory Cassette; it must bepurchased separately.

Note Memory Cassettes for the C200HS cannot be used with the C200H, andMemory Units for the C200H cannot be used with the C200HS.

When a Memory Cassette is installed in the CPU. reading and writing of theuser memory (UM) and I/O data is made possible. There is.no need for abackup power supply. The Memory Cassette can be removed from the CPUand used for storing data.

C200HS-MP16K (EPROM) The program is written using a PROM Writer. The ROM is mounted to theMemory Casette and then installed in the CPU. I/O data cannot be stored.

2-3 Expansion I/O RacksThe Backplane used to construct a CPU Rack is also used to construct an Ex-pansion I/O Rack. An Expansion I/O Rack is identical to a CPU Rack, except theCPU is replaced with a Power Supply. Two Expansion I/O Racks can be con-nected to a CPU Rack. The number of I/O Units and Special I/O Units that can beconnected to an Expansion I/O Rack is determined by the number of slots on theRack.

2-5 I/O UnitsI/O Units are divided into three groups based on the way that I/O words they useare allocated. Standard I/O Units are allocated I/O words according to the Unit'slocation on the CPU or Expansion I/O Rack. Group-2 High-density I/O Units areallocated I/O words according to I/O number set on each Unit. High-density I/OUnits classified as Special I/O Unit are allocated I/O words according to the unitnumber set on each Unit.

Note Refer to Optional Products, Appendix A Standard Models for a list of externalconnectors.

Group-2 High-density I/O Units are allocated I/O words in the IR Area (IR 030 toIR 049} by setting the I/O number switch on the front of each Unit. C-shape Unitsare allocated 2 words and D-shape Units are allocated 4 words beginning withm, where m = IR 030 + 2 x I/O number.

For C-shape Units the 16 I/O bits in m are allocated to the A side of the connector,and the I/O bits in rm-1 are allocated to the B side of the connector. For D-shapeUnits the I/O bits in m are allocated to the A side of connector 1, the I/O bits inm+1 are allocated to the B side of connector 1. the I/Obits in m+2 are allocated tothe A side of connector 2, the I/O bits in m+3 are allocated to the B side of con-nector 2. Refer to the C200HS Operation Manual (W235) for more details on I/Oword allocation.Always turn the PC power off before changing a Unit's I/O number. The new I/Onumber will not be recognized unless the PC has been turned off. Do not setmore than one Unit to the same I/O number or set I/O numbers so that the sameI/O word is allocated to more than one Unit, e.g., if you set a 64-point Unit to I/Onumber 0, you cannot use I/O number 1 for any Unit.

Refer to Appendix B Specifications for the specifications and dimensions of theUnits.

Setting the Unit Number High-density I/O Units are each allocated 10 I/O words in the IR Area (IR 100 toIR 199) by setting the unit number switch on the front of each Unit. The 10 wordsbegin with n, where n = IRlOO + 10x unit number. For example, a Special I/OUnit with a unit number of 3 would be allocated IR 130 to IR 139.

Always turn the PC power off before changing a Unit's unit number. The new unitnumber (0 to 9) will not be recognized unless the PC has been turned off.

SECTION 6Troubleshooting

The C200HS provides self-diagnostic functions to identify many types of abnormal system conditions. These functions mini-mize downtime and enable quick, smooth error correction.

This section provides information on hardware and software errors that occur during PC operation. It also provides trouble-shooting charts for CPU Racks. Expansion I/O Racks, Input Units, and Output Units.

6-1 Alarm Indicators 706-2 Programmed Alarms and Error Messages 706-3 Reading and Clearing Errors and Messages 706-4 Error Messages 716-5 CPU Racks and Expansion I/O Racks 746-6 Input Units 756-7 Output Units 76

Reading and Clearing Errors and Messages Section 6-3

6-1 Alarm IndicatorsThe ALM/ERR indicator on the front of the CPU provides visual indication of anabnormality in the PC. When the indicator is ON (ERROR), a fatal error (i.e.,ones that will stop PC operation) has occurred; when the indicator is flashing(ALARM), a nonfatal error has occurred.

Caution The PC will turn ON the ALM/ERR indicator, stop program execution, and turnOFF all outputs from the PC for most hardware errors, for certain fata! softwareerrors, or when FALS(07) is executed in the program (see tables on followingpages). PC operation will continue for all other errors. It is the user's responsibil-ity to take adequate measures to ensure that a hazardous situation will not resultfrom automatic system shutdown for fatal errors and to ensure that proper ac-tions are taken for errors for which the system is not automatically shut down.System flags and other system and/or user-programmed error indications canbe used to program proper actions.

6-2 Programmed Alarms and Error MessagesFAL(06), FALS(07), and MSG(46) can be used in the program to provideuser-programmed information on error conditions. With these three instructions,the user can tailor error diagnosis to aid in troubleshooting.

FAL(06) is used with a FAL number other than 00, which is output to the SR areawhen FAL(06) is executed. Executing FAL(06) will not stop PC operation or di-rectly affect any outputs from the PC.

FALS(07) is also used with a FAL number, which is output to the same location inthe SR area when FALS(07) is executed. Executing FALS(07) will stop PC op-eration and will cause all outputs from the PC to be turned OFF.

When FAL(06) is executed with a function number of 00, the current FAL numbercontained in the SR area is cleared and replaced by another, if more have beenstored in memory by the system.

When MSG(46) is used a message containing specified data area words is dis-played onto the Programming Console or another Programming Device.

The use of these instructions is described in detail in the C200HS OperationManual (W235),

6-3 Reading and Clearing Errors and MessagesSystem error messages can be displayed onto the Programming Console orother Programming Device.

On the Programming Console, press the CLR, FUN, and MONTR keys. If thereare multiple error messages stored by the system, the MONTR key can bepressed again to access the next message. If the system is in PROGRAM mode,pressing the MONTR key will clear the error message, so be sure to write downall message errors as you read them. (It is not possible to clear an erroror a mes-sage while in RUN or MONITOR mode; the PC must be in PROGRAM mode.)When all messages have been cleared, "ERR CHK OK" will be displayed.

Details on accessing error messages from the Programming Console are pro-vided inthe C200HS Operation Manual(W235). Procedures forthe LSS are pro-vided in the LSS Operation Manual (W237).

Error Messages Section 6-4

6-4 Error Messages

initialization Errors

There are basically three types of errors for which messages are displayed: in-itialization errors, non-fatal operating errors, and fatal operating errors. Most ofthese are also indicated by FAL number being transferred to the PAL area of theSR area.

The type of error can be quickly determined from the indicators on the CPU, asdescribed below for the three types of errors. If the status of an indicator is notmentioned in the description, it makes no difference whether it is lit or not.

After eliminating the cause of an error, clear the error message from memorybefore resuming operation.

Asterisks in the error messages in the following tables indicate variable numericdata. An actual number would appear on the display.

The following error messages appear before program execution has beenstarted. The POWER indicator will be lit and the RUN indicator will not be lit foreither of these. The RUN output will be OFF for each of these errors.

4-5 The Programming ConsoleThis and the next section describe the Programming Console and the opera-tions necessary to prepare for program input. 4-7 Inputting, Modifying, andChecking the Program describes actual procedures for inputting the programinto memory.Although the Programming Console can be used to write ladder programs, it isprimarily used to support LSS operations and is very useful for on-site editingand maintenance. The main Programming Console functions are listed below.

1, 2, 3... 1. Displaying operating messages and the results of diagnostic checks.2. Writing and reading ladder programs, inserting and deleting instructions,

searching for data or instructions, and monitoring I/O bit status.3. Monitoring I/O status, force-setting/resetting bits.4. The Programming Console can be connected to or disconnected from the

PC with the power on.5. The Programming Console can be used with C-series PCs.6. Supports TERMINAL mode, which allows the display of a 32-character

message, as well as operation of the keyboard mapping function. Refer to5-25-5 TERMINAL MODE- TERM(-) for details.

Note The Programming Console does not support all of the LSS operations, onlythose required for on-srte edHing and maintenance.

4-5-1 The Keyboard

White: Numeric Keys

Red: CLR Key

Yellow: Operation Keys

Gray: Instruction and DataArea Keys

The keyboard of the Programming Console is functionally divided by key colorinto the following four areas:

The ten white keys are used to input numeric program data such as programaddresses, data area addresses, and operand values. The numeric keys arealso used in combination with the function key (FUN) to enter instructions withfunction codes.

The CLR key clears the display and cancels current Programming Console op-erations. It is also used when you key in the password at the beginning of pro-gramming operations. Any Programming Console operation can be cancelledby pressing the CLR key, although the CLR key may have to be pressed two orthree times to cancel the operation and clear the display.

The yellow keys are used for writing and correcting programs. Detailed explana-tions of their functions are given later in this section.

Except for the SHIFT key on the upper right, the gray keys are used to input in-structions and designate data area prefixes when inputting or changing a pro-

gram. The SHIFT key is similar to the shift key of a typewriter, and is used to alterthe function of the next key pressed. (It is not necessary to hold the SHIFT keydown; just press it once and then press the key to be used with it.)

The gray keys other than the SHIFT key have either the mnemonic name of theinstruction or the abbreviatkDn of the data area written on them. The functions ofthese keys are described below.

TH

Pressed before the function code when inputting an instructionvia its function code.

Pressed to enter SFT (the Shift Register instruction).

Input either after a function code to designate the differentiatedform of an instruction or after a ladder instruction to designatean inverse condition.

Pressed to enter AND (the AND instruction) or used with NOTto enter AND NOT.

Pressed to enter OR (the OR instruction) or used with NOT toenter OR NOT.

Pressed to enter CNT (the Counter instruction) or to designatea TC number that has already been defined as a counter.

Pressed to enter ID (the Load instruction) or used with NOT toenter ID NOT. Also pressed to indicate an input bit.

Pressed to enter OUT (the Output instruction) or used withNOT to enter OUT NOT. Also pressed to indicate an output bit.

Pressed to enter TIM (the Timer instruction) or to designate aTC number that has already been defined as a timer.

Preparation for Operation Section 4-6

4-5-2 PC ModesThe Programming Console is equipped with a switch to control the PC mode. Toselect one of the three operating modes—RUN, MONITOR, or PROGRAM—use the mode switch. The mode that you select will determine PC operation aswell as the procedures that are possible from the Programming Console.RUN mode is the mode used for normal program execution. When the switch isset to RUN and the START input on the CPU Power Supply Unit is ON, the CPUwill begin executing the program according to the program written in its ProgramMemory. Although monitoring PC operation from the Programming Console ispossible in RUN mode, no data in any of the memory areas can be input orchanged.MONITOR mode allows you to visually monitor in-progress program executionwhile controlling I/O status, changing PV (present values) or SV (set values),etc. In MONITOR mode, I/O processing is handled in the same way as in RUNmode. MONITOR mode is generally used for trial system operation and final pro-gram adjustments.In PROGRAM mode, the PC does not execute the program. PROGRAM modeis for creating and changing programs, clearing memory areas, and registeringand changing the I/O table. A special Debug operation is also available withinPROGRAM mode that enables checking a program for correct execution beforetrial operation of the system.

DANGER! Do not leave the Programming Console connected to the PC by an extensioncable when in RUN mode. Noise picked up by the extension cable can enter thePC, affecting the program and thus the controlled system.

4-5-3 The Display Message SwitchPin 3 of the CPU's DIP switch determines whether Japanese or English lan-guage messages will be displayed on the Programming Console. It is factory setto ON, which causes English language messages to be displayed.

4-6 Preparation for OperationThis section describes the procedures retired to begin Programming Consoleoperation. These include password entry, clearing memory, error messageclearing, and I/O table operations. I/O table operations are also necessary atother times, e.g., when changes are to be made in Units used in the PC configu-ration.

DANGER! Always confirm that the Programming Console is in PROGRAM mode whenturning on the PC with a Programming Console connected unless another modeis desired for a specific purpose, if the Programming Console is in RUN modewhen PC power is turned on, any program in Program Memory will be executed,possibly causing a PC-controlled system to begin operation.

The following sequence of operations must be performed before beginning in-itial program input.

1, 2, 3... 1. Insert the mode key into the Programming Console.2. Set the mode switch to PROGRAM mode. (The mode key cannot be re-

moved while set to PROGRAM mode.)3. Turn on PC power.

Note When I/O Units are installed, turn on those Units also. The Program-ming Console will not operate if these Units are not turned on.

76 /~>2-f


4. Confirm that the CPU's POWER LED is lit and the following display appearson the Programming Console screen. (If the ALM/ERR LED is lit or flashingor an error message is displayed, clear the error that has occurred.)

<PROGRflM>PflSSUORD!

5. Enter the password. See 4-6-1 Entering the Password tor details.6. Clear memory. Skip this step if the program does not need to be cleared.

See 4-6-3 Clearing Memory for details.

4-6-1 Entering the PasswordTo gain access to the PC's programming functions, you must first enter the pass-word. The password prevents unauthorized access to the program.The PC prompts you for a password when PC power is turned on or, if PC poweris already on, after the Programming Console has been connected to the PC. Togain access to the system when the "Password!" message appears, press CLRand then MONTR. Then press CLR to clear the display.If the Programming Console is connected to the PC when PC power is alreadyon, the first display below will indicate the mode the PC was in before the Pro-gramming Console was connected. Ensure that the PC Is In PROGRAM modebefore you enter the password. When the password is entered, the PC willshift to the mode set on the mode switch, causing PC operation to begin if themode is set to RUN or MONITOR. The mode can be changed to RUN or MONI-TOR with the mode switch after entering the password.

4-6-2 Buzzer

<PROGRfiM>PflSSUORD!

<PRO<3RRM> BZ

Indicates the mode set by the mode selector switch.

Immediately after the password is input or anytime immediately after the modehas been changed, SHIFT and then the 1 key can be pressed to turn on and offthe buzzer that sounds when Programming Console keys are pressed. If BZ isdisplayed in the upper right corner, the buzzer is operative. If BZ is not displayed,the buzzer is not operative.This buzzer also will also sound whenever an error occurs during PC operation.Buzzer operation for errors is not affected by the above setting.

4-6-4 Registering the I/O TableThe I/O Table Registration operation records the types of I/O Units controlled bythe PC and the Rack locations of the I/O Units. It also clears all I/O bits.

l!o r°K»abKSOlUtely neoessary to register the I/O table with the C200HS When the^O table has not been registered, the PC will operate according to the I/O Unitsmounted when power is applied. The I/O verification/setting error will not occur.

initial I/O Tabte Registration

It is necessary to register the I/O table if I/O Units are changed, otherwise an I/Overification error message, "I/O VER ERR" or -I/O SET ERROR", will appearwhen starting programming operations.

I/O Table Registration can be performed only in PROGRAM mode with the write-protection switch (pin 1 of the CPU's DIP switch) set to OFF (OFF="WRlTE").

Group-2 High-density I/O Units will not be displayed in the I/O table when it isdisplayed using a host computer. Four asterisks (****}, indicating no Unit, will bedisplayed instead.

4-6-5 Clearing Error MessagesAfter the I/O table has been registered, any error messages recorded in memoryshould be cleared. It is assumed here that the causes of any of the errors forwhich error messages appear have already been taken care of. If the beepersounds when an attempt is made to clear an error message, eliminate the causeof the error, and then clear the error message (refer to Section 9 Troubleshoot-ing).

To display any recorded error messages, press CLR, FUN, and then MONTR.The first message will appear. Pressing MONTR again will clear the presentmessage and display the next error message. Continue pressing MONTR untilall messages have been cleared.

Although error messages can be accessed in any mode, they can be clearedonly in PROGRAM mode.

7-1-13 Changing Timer/Counter SVThere are two ways to change the SV of a timer or counter. It can be done eitherby inputting a new value; or by incrementing or decrementing the current SV.Either method can be used only in MONITOR or PROGRAM mode. In MONI-TOR mode, the SV can be changed while the program is being executed. Incre-menting and decrementing the SV is possible only when the SV has been en-tered as a constant.To use either method, first display the address of the timer or counter whose SVis to be changed, presses the down key, and then press CHG. The new valuecan then be input numerically and WRITE pressed to change the SV or EXT canbe pressed followed by the up and down keys to increment and decrement thecurrent SV. When the SV is incremented and/or decremented, CLR can bepressed once to change the SV to the incremented or decremented value butremaining in the display that appeared when EXT was pressed or CLR can bepressed twice to return to the original display with the new SV.This operation can be used to change a SV from designation as a constant to aword address designation and visa verse.
