One or two solenoids, composed by a central tube and a surrounding coil (5), are ﬁ tted to the body at the spool’s ends: when the coils are energized, their magnetic ﬁ eld develops a force on the oil immersed mobile plunger incorporated in the tube which pushes the control spool from the initial position into a shifted position where oil ﬂ ow is allowed from P to either A or B.With coils (5) de-energized, the control spool (2) returns to the central or initial position pushed by the washers (3) supported by the return springs (4).The coils (5) are locked on the tube by threaded plastic nuts (6); the tube incorporates an externally reachable push rod (7) which can pushed for emergency spool shifting in case of electric failure.Type L50A0L201_, L50A0M201_, L50A0N201_These valves do not have return springs (4) for the directional control spool (2): the spool can shift between two positions, driven only by the magnetic force developed by the two solenoids (5), and, when the solenoids are not energized, the neutral position of the spool is not deﬁ ned. The directional control spool holds a speciﬁ c position only when one of the solenoids is maintained energized.Type L50A0L501_, L50A0M501_, L50A0N501_In these valves the directional control spool has two switched positions, each one with a mechanical detent. Shifting of the spool’s position is achieved by energizing one of the solenoids, but it is unnecessary to maintain the coil energized in order to keep the spool shifted., RE 18305-11/06.20224/3 - 4/2 Directional valves| L50A0… (LC04-A)5Technical dataTechnical dataVoltage tolerance (nominal voltage)%-10 .... +10Duty Continuous, with ambient temperature ≤ 50°C (122°F)Coil wire temperature not to be exceeded°C (°F)180 (356)Insulation class HCompliance with Low Voltage Directive LVD 73/23/EC (2006/95/EC), 2004/108/EC Coil weight with connection EN 175301-803kg (lbs)0.18 (0.40)Voltage V12244896205 Voltage type DC DC DC DC DC Power consumption W2020202020 Current (nominal at 20 °C (68 °F))A 1.620.840.450.210.01 Resistance (nominal at 20 °C (68 °F))Ω7.428.4106.44512062NoteFor applications with diﬀ erent speciﬁ cations consult us.RE 18305-11/06.2022,6L50A0… (LC04-A) | 4/3 - 4/2 Directional valves Technical data(Ex.

Limiting valuesIn accordance with the Absolute Maximum Rating System (IEC 60134). Voltages are referenced to GND (ground = 0 V).[1]The minimum input voltage ratings may be exceeded if the input current ratings are observed.[2]The output voltage ratings may be exceeded if the output current ratings are observed.[3]For SO20 packages: above 70 °C derate linearly with 8 mW/K.For (T)SSOP20 packages: above 60 °C derate linearly with 5.5 mW/K.For DHVQFN20 packages: above 60 °C derate linearly with 4.5 mW/K.8. Recommended operating conditions9. Static characteristicsTable 6. Static characteristicsAt recommended operating conditions. Voltages are referenced to GND (ground = 0 V).[1]All typical values are measured at V CC = 3.3 V (unless stated otherwise) and T amb = 25 °C.[2]The bus hold circuit is switched off when V I ˃ V CC allowing 5.5 V on the input terminal.[3]For I/O ports the parameter I OZ includes the input leakage current.[4]Valid for data inputs of bus hold parts only (74LVCH245A). Note that control inputs do not have a bus hold circuit.[5]The specified sustaining current at the data input holds the input below the specified V I level.[6]The specified overdrive current at the data input forces the data input to the opposite input state.10. Dynamic characteristicsTable 7. Dynamic characteristicsVoltages are referenced to GND (ground = 0 V). For test circuit see Fig. 7.[1]Typical values are measured at T amb = 25 °C and V CC = 1.2 V, 1.8 V, 2.5 V, 2.7 V and 3.3 V respectively.[2]t pd is the same as t PLH and t PHL.t en is the same as t PZL and t PZH.t dis is the same as t PLZ and t PHZ.[3]Skew between any two outputs of the same package switching in the same direction. This parameter is guaranteed by design.[4]C PD is used to determine the dynamic power dissipation (P D in μW).P D = C PD × V CC2 × f i × N + Σ(C L × V CC2 × f o) where:f i = input frequency in MHz; f o = output frequency in MHzC L = output load capacitance in pFV CC = supply voltage in VoltsN = number of inputs switchingΣ(C L × V CC2 × f o) = sum of the outputs.10.1.

The front panel is fitted with an AC power on/off switch, N-Type connectors at the RF input and output ports, a standard 9-pin D-sub socket (see section 8.2.2 Status Monitoring Via the 9-Pin D-Sub Connector), and 3 LED lights indicating AC power connection (green), temperature alarm (red), and fan malfunction alarm (red). The front panel of the unit is also equipped with two handles and marking with the name, model number, frequency range, and saturated output power of unit. Slotted holes on the outer left and right extensions of the front panel allow secure mounting to a standard 19” (483mm) rack support structure.Figure 1: Front panel of HPA-272+ equipment chassisOn the rear panel of the unit is the input for a standard 85-265V AC power supply with caution label (right side). At the right of the rear panel is a clearly marked grounding terminal. It is recommended that this terminal be connected to a Common Bonding Network (CBN). On the left side of the rear panel is an identification sticker containing the model name and serial number. Two cooling fans are mounted to the center of the panel.Figure 2: Rear panel of HPA-272+ equipment chassis4 FUNCTIONAL DESCRIPTION Mini-Circuits’ HPA-272+ is a high-power rack-mountable RF amplifier capable of delivering output power up to 100W across the 700 to 2700 MHz frequency range. The amplifier provides 48 dB gain with ±1.7 dB gain flatness, +55 dBm OIP3 and 89 dB reverse isolation. It operates on a self-contained 85 – 265V AC line power supply. This model features internal cooling and self-protection against over-temperature, and is immune to open and short loads while delivering full power from the output port.The unit features LED indicators on the front panel which illuminate to alert the user when AC power is connected, when the unit temperature exceeds the maximum rating, and when the cooling fans are not functioning properly. The 9-Pin D-Sub socket allows remote monitoring of these conditions in layouts where the front panel is not clearly visible to the operator.The HPA-272+ is an ideal solution for test applications requiring high power over a wide frequency range such as EMI and antenna testing, RF power stress testing, reliability testing and more. It is also highly useful for production test applications in which it is desirable to test many DUTs in parallel such as HTOL. The amplifier can be paired with high power splitters to distribute a test signal through up to 80 channels. See section 9 for more information about applications of this equipment.5 POWER SPECIFICATIONS AND MAXIMUM RATINGS 5.1 AC Power SpecificationsParameter SpecificationSupply Voltage: ~Line85-265V : 47-63 HzPower Consumption 531W (typ.)5.2Maximum RatingsTo prevent damage to your equipment, please do not exceed any of the maximum ratings specified here and on the model data sheet.Table 1: MaximumParameter RatingsOperating Temperature 0˚C to 50˚CStorage Temperature -20˚C to 70˚C (non-condensing)Input RF Power(no damage)+7 dBm6 UNPACKING6.1 UnpackingThe equipment ships in a single large cardboard carton measuring 11 x 25.125 x 23” pictured in the figure below.Figure 5: Shipping cartonWithin the carton, the HPA-272+ unit is protected by pink foam inserts.

It is based on the functionality of MOTCON and is designed primarily for use with AC frequency converters delivered by third-party vendors.The functional unit is standardised to a high degree to simplify the work of designing presentation, dialog and control logic. The unit has many optional capabilities, which increase its operational flexibility. MOTFREQ01 normally performs its control function without help from other elements.MOTFREQ01 is used in the control of variable speed motors from Operate ITOperator Station, control desks or control organs at the motor itself. The motor can be controlled from a master control function (e.g. group start, level regulation from level gauges etc).2 ConfigurationMOTFREQ01 like other functional units is built up of two parts: •A Function Block, which is handled in the same way as other Function Blocks in the ABB Controller 800M range of products. Figure 3.1 illustrates the terminals on the function block.•A section for operator functions, which consists of presentation and orderfunctions. Data and parameters from the process are presented on an Operate ITOperator Station. The keyboard of the Operate ITOperator Station is used by the operator to enter commands which control the operation of the functional unit. The response to the operator's intervention is shown on the display screen of theOperate ITOperator Station. The application work for this part is normally limited to the arrangement of the display. Figure 2.1 shows the structure of the functional unit.PROCESS OBJECTFigure 2-1.

However, it is also possible to select other modes of control and thuscontrol MOTFREQ01 from other locations.All the control modes can be selected from the central operator station. The LOCALcontrol mode may also be selected from the local control station.The different modes of control are as follows:• Jog• Local• Manual• External 1• External 2By selecting control mode, the operator decides from which location the motor is to becontrolled. All control modes may be selected through dialog in Operate IT OperatorStation. The LOCAL control mode may also be selected from the local control stationthrough the Function Block input :LE, provided that the current control mode is neitherJOG, nor DISABLE.For the different control modes, MOTFREQ01 is controlled as follows. For a summary ofthe control modes, see Table 3-1.Functional Unit MOTFREQ01 Functional Description4.2.1 JOGT he control mode JOG is suitable for testing the motor in the field. The motor issupposed to be controlled from a stop/start station adjacent to the motor. Control from other locations is blocked.The supervision of interlocks is limited. Only the safety interlocks SafetyInt1 and SafetyInt 2 as well as faults in the control voltage chain (the inputs :M1 - :M5) prevent starting. The motor is started and stopped through the inputs :JogStart and :JogFunc.:JogStart, Start order from field-mounted start/stop station :JogFunc, Stop/Hold function from field-mounted start/stop stationThe function of these inputs is set out in tabular form below. :JogStart :JogFunc0 0 Stop order. 0 1 No change.1 0 Start and stop order in :JogStart input.1 1Start order on :JogStart and stop order on :JogFunc.When :JogFunc=1, the motor is stopped by breaking the control voltage chain, i.e. signified by any of the :M1 - :M5 inputs going low.4.2.2 LOCALT he motor is controlled from a local desk or panel. Control from other locations is blocked.LOCAL control mode, like other points of control, may be selected from Operate ITOperator Station. In addition, LOCAL control mode may be selected from the local control panel through the input :LEnbl as follows::LEnbl = 1: The control mode is LOCAL, as long as the Operate ITOperator Stationoperator does not request JOG or STAND BY. All other control modes are blocked and :LEnbl must be released before a mode change can occur.LEnbl -> 0: MOTFREQ01 resumes the either the previous or the latest control modecalled for from Operate ITOperator Station.Functional Unit MOTFREQ01 Functional DescriptionThe operator controls the motor through the inputs :Lstart and :LStop. :LStop Local stop order (active low) :Lstart Local start orderThe function of these inputs is set out in tabular form below. :Lstop :Lstart 0XStop order. Note In order for the motor to start when LStop has been low, LStop must be set high and LStart must make a low-to-high transition1 0 No change 1 1 Start order4.2.3 MANUALThe motor is controlled from Operate ITOperator Station. Control from other locations is blocked. This is the default control mode. To start, the operator has to press the key START. To stop the motor, the key STOP has to be pressed.4.2.4EXTERNAL 1 and EXTERNAL 2The motor is controlled from external signals, e.g. from a process signal. Control from other locations is blocked. This mode is e.g. used for on/off control of levels and for automatic start up and shutdown of belt conveyors etc.EXTERNAL 2 functions in exactly the same way as EXTERNAL 1. EXTERNAL 2 is used when the motor is to be controlled by Level 2 application software e.g. Auto Series Software.The function is enabled by inputs :SeqE1 and :SeqE2.The process controls the motor through the inputs :E1Start, :E2Start and :Stop. Theoperator is able to stop the motor by issuing stop order from Operate ITOperator Station. The control mode then changes to Manual, to prevent the motor from being restarted. :Stop Stop order (active low) :StartE1(2) Start orderThe function of these inputs is set out in tabular form below: :Stop :StartE1(2) 0 X Stop order 1 0 -> 1Start order:StartE1(2) are dynamic inputs, i.e. they trigger on the rising edge.4.2.5 DISABLEDThe motor is stopped and all orders to it are blocked. Used to take the motor Out of Service.4.3 SetpointModesAs for the Motor Control Modes above the speed setpoint can also be entered from a localcontrol station (the frequency converters control panel), or from the Operate IT OperatorStation or from a program in the AC800M.The different setpoint modes are as follows:• Local• Manual• ExternalBy selecting setpoint mode, the operator decides from which location the setpoint is to becontrolled. All setpoint modes may be selected through dialog in Operate IT OperatorStation.There is no correlation between motor control modes and setpoint modes i.e. when themotor is controlled using LOCAL this does not mean that the Setpoint changes mode toLOCAL too. If this functionality is required then the logic will need to be programmedexternally to the function block. All motor control modes are not affected by changes in theSetpoint modes.For the different setpoint modes, MOTFREQ01 is controlled as follows:Setpoint4.3.1 LOCALThe LOCAL setpoint mode may be selected from the local control station by using theFunction Block input :MV_Lenbl, or through the dialog in Operate IT Operator Station,provided function block is not disabled. All other setpoint modes are blocked and:MV_LEnbl must be released before a mode change can occur.The setpoint mode LOCAL is suitable entering a Setpoint from the frequency converter orfrom a local panel next to the motor. Setpoints from other modes are blocked. The outputterminal :SP_Local in the function block is set true indicating the mode is active.In LOCAL mode the output terminal :SP_OUT does not provide a setpoint to thefrequency converter because the frequency converter itself is providing this. The value ofthe Speed Indicator Input: MV is transferred to the output terminal: SP_OUT.4.3.2 MANUALSetpointThe MANUAL setpoint mode is selected by using the Function Block input: SeqManSP orthrough the dialog in Operate IT Operator Station, provided that function block is notdisabled.When in MANUAL setpoint mode it is possible to change the speed of the motor byentering the desired setpoint. Setpoints from other modes are blocked but it is stillpossible to change to these modes from the dialog in Operate IT Operator Station. Thedesired value is then available on the output: SP_OUT terminal. The output terminal:SP_Man in the function block is set true indicating the mode is active.4.3.3 EXTERNALSetpointThe EXTERNAL setpoint mode is selected by using the Function Block input: SeqExtSPor through the dialog in Operate IT Operator Station, provided that function block is notdisabled.The EXTERNAL mode enables a setpoint to be provided from an external signal e.g. froma PID controllers output. Setpoints from other modes are blocked but it is still possible tochange to these modes from the dialog in Operate IT Operator StationThe value at input terminal :EXTREF in the function block is then available at the outputterminal: SP_OUT. The output terminal: SP_Ext in the function block is set true indicatingthe mode is active.Speed4.4 SetpointTerminal :Speed1 is a coefficient used to restrict the ramp speed of the setpoint. Thevalue entered is the slope of the curve required. This value will depend on the range of thesetpoint. All setpoint changes are restricted by the ramp speed in all modes exceptingLocal setpoint mode. When changing to local mode from manual mode and external modethe local modes setpoint is indicated directly. In Local mode the setpoint is only displayedin MOTFREQ01, and setpoint speed has no affect.Setpoint Speed Coefficient = Setpoint Range / Ramp Time RequiredTracking4.5 SetpointThe setpoint tracking function is enabled by terminals :Track_A and :Track_B.Track_A is used to retain the external setpoint when changing mode from External toManual.Track_B is used to retain the local setpoint when changing mode from Local to Manual. 4.6 Ready for StartReady for start means that all the interlocks are satisfied, that there are no alarms andthat the control mode is not JOG or that the control is DISABLED.Ready for start is indicated by the MOTFREQ01 displays in the Operate IT OperatorStation and by the output terminal :RFS (Ready For Start) in the function block.4.7 ReadyThe output terminal: READY has the same functionality as the terminal: RFS but themotor has to be in External 1 or External 2 mode for the output to be set. This terminal isused in sequence applications to check the status of the motor i.e. when the motor is partof a sequence or group start.4.8 Start-upAn initialisation phase begins at start of the AC800M system.The result of this becomes:The outputs are reset (to zero) except for the ManInd terminal, which is set (to 1).Manual is the default control mode at system initialisation for both the motor and thesetpoint. With additional function block logic it is possible to force the control mode toother modes at system initialisation.4.9 InterlocksThe motor control can be interlocked by signals from the process and also by signals fromthe control logic. The interlocks are divided into four groups with the followingdesignations and functions.Safety Interlocks, which interlock the object for safety purposes. The two safetyinterlocks, :IC1 and :IC2, cannot be blocked.Process Interlocks. There are 4 normal process interlocks, :IB1 to :IB4. All four interlockscan be configured to accept blocking by the operator. All four interlocks can also beconfigured as start interlocks. A start interlock will prevent the motor from starting, but willnot stop a running motor.External (Sequence) Interlocks. Interlocks on terminals :IA1 and :IA2 are used if theobject is to be interlocked against other objects such as a pump motor or a group start orother conditions in an automatic sequence. These interlocks are configurable as blockedor not when not in E1 resp. E2 mode and the interlocks are not included in the conditionsfor indication of Ready for start.Run Interlocks. The inputs :RunInt1 and :RunInt2 are intended for connection tooperation monitors to obtain tripping or alarm in the event of faults. The inputs are to beTRUE when the equipment is faultless. In order to allow the motor to reach operationalspeed, RunInt1 and RunInt2 are blocked during the time :T3 after start-up. When theJOG control mode is selected, RunInt1 and RunInt2 are blocked. When RunInt1 orRunInt2 goes to 0, MOTFREQ01 remembers this error status until the alarm isacknowledged. Input :RunInt1 has a motor tripping function whereas the input :RunInt2function can be controlled with the parameter :RunInt2F. When input :RunInt2F = TRUE,the motor is tripped. With .RunInt2F = FALSE, only an alarm is given. Alarm handling of:RunInt1 and :RunInt2 is blocked internally in the Function Block with the motor atstandstill.An interlocking is active when the input is 0 (FALSE). All Process and External interlocksare blocked when the JOG control mode is selected.Alarms4.10 MotorInput terminals :MotTemp indicates that the motor has overheated. Terminal :BearTempindicates that the motor bearings have overheated. Both inputs terminals do not trip themotor but provide and alarm to the operator.4.11 Start and StopStart and stop commands for MOTFREQ01 may originate from dialog with Operate ITOperator Station or from Function Block inputs, depending on the control mode selected(See Section 4.2 Motor Control Modes, and Table 3.1).When a start command is issued to MOTFREQ01, it is forwarded to the motor through theFunction Block output :SO1 (Start order 1, Forwards/ High). See Section 4.11.2 StartOrder Selection. The start order on the output :SO1 is a pulse with a duration which isdetermined by the input :T1.The main contactor of the motor acknowledges the start order :SO1 by setting the input:ACK1 high. The main contactor must acknowledge within the time determined by theinput :T2. The time T2 ought to be set longer than T1.If the main contactor acknowledges the start order pulse :SO1 within the time T2,MOTFREQ01 sets the start order output :SO1 high and keeps it high. The time T3 afterthe main contactor having responded, MOTFREQ01 starts supervising the motor current.The time T3 is determined by the input :T3If the main contactor does not acknowledge the start order within the time T2, the startattempt is deemed abortive. Consequently, MOTFREQ01 issues an alarm about thecontactor failure and a new attempt at starting may be made.The contactor failure alarm indication on the object display of MOTFREQ01 disappearswhen the operator acknowledges the alarm.MOTFREQ01 also issues an alarm about main contactor failure when the contactoracknowledges start orders falsely, i.e. when it sets the inputs :ACK1 high without any startorder being issued. MOTFREQ01 transmits the alarm the time T2 after the input havingbeen set.4.11.1 Start and Stop Order at Different Motor Control ModesThe table below describes the commands which can be given at the different controlmodes of MOTFREQ01.Table 3-1.

This means that if the Input :M1=0, the inputs :M2 - :M5 are not regarded etc. The signal ME interlocks the completeevaluation. ME=0 is used to prevent incorrect alarms with, for example, a total controlvoltage failure. The inputs M1 to M5 are to be TRUE when there are no errors. Theevaluation presupposes that the control circuit consists of a number of breaking contactsin series. Alarm handling of M1 to M5 is blocked internally in the Function Block with themotor at standstill.4.13 Supervision of Load ControlThe input MC is connected to the process signal for LOAD indication (Motor Current inMOTCON). This input on the function block is scalable and can be used to present themotor current or more aptly for frequency converters, the torque or power indication. Inthe function block the correct measurement range and engineering units can be entered.These will then be presented accordingly in the Faceplate and Object display in theOperate IT Operator Station.Info: Most modern AC Drives are have programmable outputs so that the correct signalcan be configured for power or torque and sent to the MC input.Window4.14 InteractionThe interaction window is available in the Control IT Control Builder. The interactionwindow is an engineering aid used to simplify configuration and blocking of signals notavailable on the faceplates.

Information flow representation1. Data flow2event start => customer => selection_product => selection_pay,delivery =>=> final_decision =>end1 See App.12 see App.21III.Functional Descriptiona. Functional partitioningThis on-line shopping system is partitioned into three functions: processing user ID, selecting computer-related products, and choosing payment & shipping patterns.b. Functional description31. Restrictions / limitationSince time is very limited, the first product does not included a report, which can be handed in the supervisor, so that this on-line store can be operated more systematically. Those customers can not receive our shopping news monthly.Now the on-line order is limited in the North America since the mailing fees would be very high if we sell products to other countries. We will improve it in the future.This on-line store can only be useful for USD and Canadian Dollars.Since the order of mainframe is very limited, now we do not keep kinds of products in our product inventory.2. Processing narrativeIn “processing user ID” function, since this system is only available for some one who is in North America, this function can not process the address which is out of USA and Canada.In “selecting computer products” function, mainframe will not ava ilable and not every brand included.3. Design constraintsThe customer can only cancel the order before “selecting payment & shipping pattern” function. Once the customers input the credit card numbers or other payments pattern, they can not drop the order. We will provide verification before they input the payments pattern so that they will know the order can not be dropped. But if the customer is not satisfied with the products, we have the full-refund policy.Any customer who wants to order products, he or she must have user ID.3 See App.3234. Supporting diagramsc. Control Description 41. Control specification. When the products ordered by a customer is out-of-stock, display “ It is out-of-stock now”. When the customer inputs other country’s address, display “ It is only available within North America”.. When the customer cancel the order or do not want to enter this web page further, go back.2. Design constraintsCustomer will not be allowed to drop the order after he or she had selected payment and mailing patterns.IV. Behavioral DescriptionThere are 3 levels of State Diagram.a. State Diagram Level 15 We have 4 states such as Reading User Input, Select Computer Component, Check User ID and Choosing Payment Pattern. Each state has an external event that causes the system to change state. From Reading User Input State, there are two options that customer can select. First, when customer selects shopping button on screen, the shopping page (Select Computer Components page) will be activated. From Select Computer Components stage, if customer selects item that he wants to buy or exit the program, the stage “Choosing Payment Pattern” will be activated. After he selects payment pattern, the software will invoke input screen again for waiting customer input. The second option is to create customer profile in database. After creating customer profile, customer can select computer that he wants to buy or exit program.4See App.4 5See App.5b. State Diagram Level 2 61. For Selecting Computer ProductsWe have 3 states: Reading User Input, Selecting Computer Products & Brands and Calculating Expense. Each state has an external event that causes the system to change state.From Reading User Input, when customer wants to buy a product, the software will invoke the shopping page. After the customer selects product & brand that he wants to buy, the software will invoke calculation expense of the product.2.For Processing Customer ID & Display InvoiceWe have 4 states: Reading User Input, Check Customer ID, Creating Customer ID and Displaying Customer Information & Item Selected. Each state has an external event that causes the system to change state. From Reading User Input, when customer wants to buy something, he has to put customer ID. If he is not a member, the software will invoke Creating Customer ID page. If he is a member and he wants to display product that he chose in the past, the software will invoke Displaying Customer Information & Item Selected Page.3. For Selecting Payment & Shipping PatternWe have 3 states: Reading User Input, Select Payment & Shipping Pattern andcalculating total expense. Each state has an external event that causes the system to change state. Form Reading User Input, when customer selected products and brands already, he has to select payment and mail pattern to pay his products. After that, the software will invokeTotal Amount Page that customer can understand how much he has to pay for the product.c. State Diagram Level 371. For Display Customer IDWe have 4 states such as Reading User Input, Display Information, Update Information, and Customer checks order. Each state has an external event that causes the system to change state. From Reading User Input, when customer selects the product that he wants, before he submits the process, the confirmation page will show him to confirm the product that he selected. In this level, he can also select the button display ordered product that will show him about the list of product that he bought, total price and type of shipping.6 See App.67 See App.745V. validation and CriteriaOne of the requirements in this software is interactive web site: which means "ZERO MAINTENACE" in web site and company database both. The customer ID is produced indatabase automatically and obtained when the customer wants to get it. And when the customer summit, the data is updated automatically.T esting for Maria’s on -line computer storeCase testing: White box tests are done by Jin-Tak and NarumonPDL:1 Do until finish shopping2 Input product & brand3 If the quantity of product is null4 then display “out -of –store” go back 25 else update cart store6 calculate sum of prices7 if products are not correct8 then go back 29 else input payment & mail pattern 1011 12 13 14 15 16 17V(G)=6E-N+2=6P+1=6Basis set:Path 1: 1 2 3 5 6 7 9 10 15 16 17 18 19Path 2: 1 2 3 4 2 3 5 6 7 9 10 15 16 17 18 19Path 3: 1 2 3 5 6 7 8 2 3 5 6 7 9 10 15 16 17 18 19Path 4: 1 2 3 5 6 7 9 10 11 12 14 17 18 19Path 5: 1 2 3 5 6 7 9 10 11 12 13 19Black Box Testing:For function “Selecting Computer Product”Does it calculate the sum of prices correctly?Does the cart store show the correct information?For function “Selecting payment & shipping pattern”If the products are not what customers want, can they go back shopping?For function “Purchase items”Can we identify the customer-ID correctly?Can we build customer-ID correctly?Does the “ Display customer information and items” show the information correctly?67VI.

Product description1.1 Applicationz The Compur Monitox plus warns the user when a toxic gas is present or oxygen deficiency occurs.z It should be worn near the breathing zone.z The display shows the actual gas concentration in ppm, ppb or %/Vol.z The Compur Monitox plus is not designed to monitor process gas streams or permantlyhigh concentrations.z Wear the instrument near the breathing zone using the clip or neck chain.z The filter cap should be protected from dripping water and exposure to excessive dust.z The Monitox comes with a steel clip and neck chain. A suspender and belt clip are optional.Move switch in “TEST”position : Electronics, batteries,speaker, LED and Display will be tested.Move switch in “ON”position: Now you can test the Monitoxusing the optional gas generator. Depending on the gasgenerator model, the black switch pin is operatedautomatically or must be held down manually.The gas generator produces a test gas for 10 seconds.The test gas concentration is slightly above the alarmthreshold. After 10 s the gas production stops automaticallyand the green LED of the generator goes off.Within these 10 seconds the Monitox should give an alarm.1.3 EarphoneFor use in a loud environment the optional earphone can be connected to jack (9).1.4 StorageShort term: Switch in position “OFF”.More than 1 month: Remove sensor and battery pack.2. CalibrationMove switch in position “TEST”.Press the button marked “Cal”, using the supplied pushpin.The display will show “000”flashing until the zero has been adjusted. This procedure must be done in a clean atmosphere. Now the display will alternate between “GCAL” and “ICAL”. To start a current calibration push the cal button while “ICAL” is active, to start a gas calibration push it when “GCAL” is active.2.1 Gas calibration- Place Monitox plus gas adapter (part # 569747) securely on the filter cap.- Connect span gas.NOTE: If using HCN, Cl2 or other corrosive gases, use non-porus tubing such asTygon lined with teflon or polypropylene.- Open gas cylinder. The recommended flow is 250 ml / min, for Phosgene: 500 ml / min.-Now push the “CAL” button while “GCAL” is active. The display flashes “GCAL”.- When “GCAL” is steady, a stable measured value has been reached.- Close the gas cylinder.- Push “Cal” button.- Now the display shows the most recently used span gas concentration. Confirm by pushing “Cal” or alter by pushing and holding “Cal”.- Your operation will be confirmed by the unit displaying “Stor”.- The Monitox will now perform another self test and then show the actual gas concentration. - Move switch to “ON” position.2.2 Current calibrationThis procedure must only be done when using new sensors. You can find the sensor specific current on the sensor label.Push the “Cal” button while “ICAL” is active on the display.Now the display shows the current of the sensor that has most recently been used. If the current on the display is correct, confirm it by moving the switch to “ON”, or alter by pushing and holding the “Cal” button.2.3 Oxygen sensorThe calibration procedure is the same as above, but you can use fresh air as span gas. Fresh air always contains 20,9 % oxygen. Zero can be adjusted with pure Nitrogen (GCAL) or electronically (ICAL).3. Alarm thresholdsCompur Monitors recommends to strictly observe the local regulations for the alarm thresholds. Open the instrument. Use proper safety measures for handling CMOS components.Place switch in “TEST” position.Following the normal self test which occurs when powering on, push button “A1”. The display will now show the active alarm threshold and an arrow. To increase the threshold push and hold “A1”. To decrease the threshold push and hold ”A2”. If the desired alarm threshold appears on the display release the button and thus save the new value. Now move the switch into position “ON”.Follow the same procedures for setting the alarm threshold for A2.4. Maintenance4.1 Filter cap replacementCarefully turn the old filter cap 90° counter clockwise. Insert the new filter cap. Turn 90° clockwise. Make sure to use only filter caps for the relevant gas!4.2 Sensor replacementRemove filter cap. Pull sensor out. Some sensors are shipped with a plug that short circuits the contacts. Remove this. Check best before date of the sensor. Note the output current, which is on the sensor label. Perform a current calibration.4.3 Battery replacementOpen the instrument. Disconnect and remove the battery pack. Remove battery pack cover. Replace the batteries. Observe the proper polarity, as is illustrated on the battery pack cover. Close, connect and mount the battery pack. Perform a functional test.5.
