1.10 The equipment may be configured as a Non-Preset System (Fig 1.2) or as a Preset System(Fig 1.3). The Non-Preset System may be configured as a combination display, i.e. to displayVolume & Weight on the same display.

1.11 More control of the loading process can be achieved by linking Masterload to an office computersystem. Data collected from Masterload is transferred automatically to the office where a receipt canbe printed.

1.12 The ability of Masterload to control a Preset Valve ensures that batch delivery is to a programmableflow profile with a highly accurate cut-off, within +0.05/-0 litres of target (Fig 1.4).

1.13 Masterload can take additional information from 4 external transducers. In this way, differentialpressure, two pressure measurements and density may be monitored.

1.14 Transducers used to pass this information to Masterload, will provide a 4-20 mA signal.

3 PULSE TRANSMITTER UNIT

3.1 The electronic pulse transmitter is mounted directly onto the Avery--Hardoll bulkmeter capsule withinan O ringed weatherproof enclosure.

3.2 In construction, the transmitter consists of a PCB and chopping disc that rotates with the meteroutput shaft. As the disc rotates three light beams (channels) are interrupted to produce a series of pulses (or trains). One revolution of the meter produces 227 pulses from each channel which are fedto the Masterload Display Unit via a screened cable.

3.3 As the transmitter is factory--set, there is no requirement to adjust the pulses since each channelproduces a square wave of 50% +/--10% duty cycle (mark--to--space ratio).

4 POWER SUPPLY UNIT

4.1 The Power Supply Unit is a flameproof enclosure which provides an Intrinsically Safe 10V dc supplyfrom either a 110V or 240V a.c. mains supply. The unit should be mounted in a convenient position

where access can be achieved, this will aid both installation and any future maintenance requirement.

4.2 The components of the Power Supply Unit are housed in a flame-proof (EEx d) cast aluminium boxsealed to IP65 specification. Cable entry is via safety authority approved brass glands screwed intothe base of the box. (Fig 2.4).

4.3 The Power Supply Unit main components are:

Power supply PCB incorporating a maximum of 11 solid state relays (SSRs), together with amicroprocessor circuit.

One barrier block comprising seven independent barrier stages.

4.4 A cable separation sheet is fitted over the lower section of the power supply PCB to separateIntrinsically Safe wiring from the Non-Intrinsically Safe input supply.

FIG 2.3 COMBINED DISPLAY


15/104

TP 0027


4.5 There are a number of versions of PCB fitted to the Power Supply Unit, these are determined by thesystem requirements e.g. Preset/Non-Preset, Analog Interface, etc. and either 110V or 240V. Whenordering a system, the intended input must be stated to ensure that the correct board is factory-fittedto the Power Supply Unit. A 1A anti-surge fuse (FS1) is mounted on the PCB to protect the powersupply input.

FIG 2.4 POWER SUPPLY UNIT COMPONENTS

PCBBARRIER BLOCK

SEPARATION SHEET

ANALOGUEINTERFACEBOARD

4.6 The PCB has the ability to generate a power fail signal should power loss to the system occur. The

signal is routed to the microprocessor housed in the Display Unit, requesting all system data to bestored in a Non-Volatile Memory (NVR). The master or primary Display Unit will continue to displaydata for 15 minutes whilst any repeater or additional display units will lose their displayed information.

4.7 A barrier block is mounted on insulated pillars in front of the Power Supply PCB to provideIntrinsically Safe connections between the Power Supply Unit and Display Unit. As the PulseTransmitter is supplied from the Display Unit, this too becomes an intrinsically safe enclosure.

4.8 The Barrier is an Intrinsically Safe encapsulated module. It incorporates components manufacturedand approved to safety authority specification to limit excess current and voltage from reaching unitsmounted in a CATEGORY 2 (ZONE 1) HAZARDOUS AREA.

4.9 The Solid State Relays (SSR) are controlled by an Intrinsically Safe data link between the Displayand Power Supply Units.

4.10 The power switched by the SSR is derived from an input permissive feed which is usually suppliedby an external interlock circuit and may be 110V or 240V a.c.. If the permissive feed is removedduring a delivery the transaction will be suspended.

4.11 The SSRs are numbered SSR1 to SSR11. SSR1 and SSR2 will operate a preset valve. SSR3 maybe used to operate a pump demand signal. SSR4-11 are used to control external devices (e.g.additives).

4.12 On a Non-preset system, only one relay (SSR3) is fitted to the Power Supply Unit. This will generatea pump demand signal, unless the Masterload system alarms, in which case this demand signal willbe removed.

4.13 When an interface to a densitometer or D.P. gauge is required, a small interface board is also fitted.This analogue interface board simply plugs into the power supply board and may be added at anytime.


16/104

TP 0027


4.14 If an external interlock is not required, the PSU may be configured to use the existing supply voltagefor uninterrupted valve control.

5 DISPLAY UNIT

5.1 The Display Unit provides a readout of information shown on liquid crystal displays (LCD) mounted on

a display PCB. Push buttons on the front panel of the unit allow the operator to set loadingparameters. Incoming and outgoing signals are routed through a microprocessor PCB.

5.2 The display PCB, microprocessor PCB and associated cables are housed in a cast aluminium boxformed in two halves and secured together by four cap head screws. The box is sealed to IP65specification. (Fig 2.5).

5.3 A toughened glass facia fitted to the front half of the Display Unit is held in place by a rubbersurround, together with its associated Dial Mask.

5.4 The Display Unit is Intrinsically Safe and may be mounted where convenient. For mounting andwiring details refer to Chapter 4, Installation.

5.5 The display PCB is held in place on the front half of the Display Unit by a narrow groove in the rubbersurround.

5.6 The display PCB contains the driver circuitry for push buttons and LCDs. It is connected to theprocessor board by a short ribbon cable.

5.7 The display unit comes in various forms, preset, non-preset, temperature or non temperature reading,and a variety of different units of measure.

5.14 Non-preset systems have only one push button for a simple Reset operation.


18/104

TP 0027


5.15 Preset systems have three push buttons:

Reset - for Zeroing the batch display

Preset - for selecting a preset quantity

Stop/Run - for controlling product flow operations.

5.16 The microprocessor PCB is mounted at the rear of the Display Unit. The microprocessor logiccircuitry receives an Intrinsically Safe 10V DC input from the Power Supply Unit. Signals receivedfrom the Pulse Transmitter are monitored by the microprocessor and organised to give the requiredvolume.

5.17 The microprocessor also transmits control signals to the solid state relays in the Power Supply Unitand receives data via the push buttons (and temperature probe if fitted).

5.18 The Masterload II system uses a number of locations within its memory to control and configure itsoperation. Each memory location is called a Flag. Flags are divided into High and Low securitylevels depending on their relevance. A set-up push button mounted on the microprocessor PCB willaccess these flags after a sealed blanking plug on the underside of the Display Unit has beenremoved. Operation of the set-up button enables all of the data settings (Flags) in themicroprocessor software program to be reviewed and altered. Low security (Flags) can be altered byusing either the set-up button or the reset button on the front of the Display Unit using a specialpasscode entry mode. Flags are described in more detail in paragraph 7 of this Chapter.

5.19 Should the system suffer power loss, all totaliser, calibration factors and set-up data are retained foran indefinite period using a special memory device called a non-volatile random access memory(NVR) on the processor board. The NVR requires no power for data retention.

5.20 The Masterload II system uses a sophisticated communication protocol which enables an interface toa computer or SCADA system. This will enable the facility of controlled loading operations and thecollection of all loading activity data.

5.21 Information available using the data link includes: Batch Quantity (uncompensated) Tote

Batch Quantity (temperature compensated) Weight Pressure Temperature

Differential pressure Error codes

6 REMOTE DISPLAY UNITS

6.1 Remote Display Units may be installed in addition to the main Display Unit. This gives the facility forfixing a display in a more convenient location.

6.2 The software is configured by flag setting on the main Display Unit and by links on the Display PCB,the next unit in the system can be made to either repeat the information displayed on the previousunit or display supplementary information, such as temperature compensated volume or weight.

6.3 Remote Display Units may be fitted with pushbuttons to match the functionality of the main display.

6.4 The maximum cable length between displays is 50 metres.

7 FLAGS AND ERROR MESSAGES

7.1 By programming various Flags within the microprocessor software Masterload may be configured tomeet current and future requirements.

7.2 The software contains various entry points called Flags.

7.3 Each Flag has a two digit identity number in the range 00 to 90.

7.4 Each flag is accompanied by a simple message, displayed in the Tote window, to indicate its function.

7.5 The Flags are given two levels of security in the Masterload software:

Low Security Flags numbered 01 to 13 High Security Flags numbered 20 to 90

7.6 Flags may be accessed by 2 modes:

Low Security Entry

High Security Entry

7.7 Low Security mode can be accessed by pressing the RESET push button on the Display Unit front forten seconds. This will enable the Low Security Flags to be changed and the High Security Flags tobe viewed. This Low Security Entry Mode will only be available once a four digit passcode is entered.The passcode is programmed into Masterload during commissioning.

7.8 The Low Security Flags contain information for:

System Configuration and Units of Display (Non Resettable) - for reference only Temperature Display Format and Alarms

Density Correction Factor

Preset Flow (profile and form).

7.9 High Security mode may be accessed via a SET-UP push for on / push for off button. This modegives complete access to all Flags both high and low security.

7.10 The SET-UP button is only accessible from underneath the Display Unit and involves breaking a leadsecurity seal and removing a blanking plug.

7.11 The High Security Flags contain information for:

Mode of Operation (calibration, diagnostics) Data Communication Configuration

Class of Calibration (1, 2, 3 or 4) Temperature Correction

Calibration Factors Low Security Passcode

Datum shift Display Configuration

Peripheral Interface Configuration

7.12 Flag 00 is unalterable and contains factory pre-set data defining the system (i.e. single, double ortriple capsule, readout in litres/gallons etc. and issue of program software in use.)

7.13 Flag 20 is used to enter the low security entry passcode. For example, if a flag value of 1234 is set,then when this passcode is entered, access to low security mode is enabled. Flag 20 set to 0000allows access to low security flags without passcode entry. If a flag value of 9999 is set, access forflag setting is denied; this can only be overruled by breaking the security seal and removing the

blanking plug underneath the Display Unit to gain access to the SET UP button.


21/104

TP 0027


7.14 The microprocessor has the ability to sense any faults that may occur during product delivery. Errorcodes will be transmitted from the microprocessor to the Display Unit and displayed in the Flow Ratewindow. Error messages will be displayed in the TOTE window. These messages and the necessarycorrective actions are explained in Chapter 6. If an error is detected, the deadman supply feed will beremoved.

7.15 Flag details and set-up procedures are explained in Chapter 5 Commissioning and Chapter 6Operation.

D1 0 Normal operation (i.e. not set for automatic calibration).1 The meter is set to be calibrated automatically by the Masterload Autocal system

(ref. Manual TP0038).

D2 0 Normal operation (i.e. not set for transmitter mark/space test).1 The totaliser display is used as a transmitter pulse monitor. Three ratios are shown giving

the high (i.e. mark) portion of the pulse from each transmitter channel. If any channel ispermanently low, the display will indicate Lo similarly, a permanent high will be shown asHi. Three examples are shown below.

a) No flow Hi Lo Lob) Correct setting during flow 50 48 49c) A channel 1 fault. Hi 50 48

This test is designed as a quick test for the service engineer to monitor the transmitteroutput pulses by using the passcode entry (i.e. without breaking the setup button securityseal). If no buttons are pressed and no pulses are seen by the meter (i.e. the flow hasstopped) then the meter will revert to normal mode after a period of 30 secs.Refer to Flag 22 for a permanent test facility.

D3 0 Local mode ( LINKED Flag 70)The system is set to function in a stand-alone situation without control from Flowmaster.

D1-D4 The first stage flow rate for the operation of a preset valve. This is useful for minimising therisk of static discharge when filling an empty tank. Typically, a Figure of 10% of themaximum flow rate is used. This setting is only available in tens of units(i.e. the least significant digit is fixed at 0)

Example: 0250Flag 11 (LINKED Flag 60 )

D1-D4 The first stage volume for the operation of a preset valve. This is used with Flag 10 andshould match the volume required to cover the filling nozzle. As above, this setting is onlyavailable in tens of units.Example: 0180


D1-D4 The maximum flow rate for the preset valve, with the least significant digit fixed at 0.Example: 3450


D1-D3 The flow deceleration rate (i.e. the reduction of flowrate/sec.) when controlled by a presetvalve. Typically set to 150.

D5-D6 The volume allowed to pass through the control loop pipework (at 2-4 lpm.) during the finalstage of a preset delivery (range 0-9.9). Refer to the Preset Valve Manual (TP0020) formore details. This is typically set to 1.0 litres.

8 HIGH SECURITY FLAGS

Flag 20

D1 This digit is inaccessible except when used with an Electronic Repeater System(ref. TP0002).

D3-D6 A four digit passcode (0-9999) used to gain entry to the Flag settings (refer to Ch2).When set to 9999 the passcode entry is disabled.

Flag 21

This Flag is used to set the calibration class (i.e. the number of calibration points to be used) and themaximum (100%) flow rate to be used for the calibration process. The more calibration pointsselected the more accurate is subsequent measurement. However, the greater the number of points,

the longer the calibration process takes.

D1 1 Calibration class 1 (8 calibration points at 5%, 10%, 15%, 20%, 50%, 75%, 100% of themax. flow rate (D3-D6)).

2 Calibration class 2 (4 calibration points at 10%, 20%, 75%, 100% of the max. flowrate (D3-D6)).

3 Calibration class 3 (2 calibration points at 20% and 100% of the max. flow rate (D3-D6)).4 Calibration class 4 (1 calibration point at 100% of the max. flow rate (D3-D6)).

D3-D6 A four digit (0-9999) maximum flow rate setting for calibration. The above calibrationpoints are calculated using this as the 100% Figure. When calibrating the meter, it isimportant to establish that this flow rate is obtainable.

Flag 22

This Flag provides test facilities and calibration settings.

D1 0 Normal setting.1 This setting mimics the actions of the mark/space test of Flag 07, However, unlike Flag 07,

the test does not time-out.2 This setting isused during calibration (ref. Ch.5) toallowthe meter to display volume that isuncalibrated (i.e. raw data). Any calibration Figures previously entered are unused andstored away. During this mode, any preset valve control is disabled.

3 Verification mode. Calibration factors are used by the meter and the display shows units in1/100s. During this mode, any preset valve control is disabled.

4 Self test. This provides an aid to fault finding. Masterload will automatically cycle throughthe following tests: Displays, Relays, Office and Program. To stop the test and manuallystep through, hold the Reset button until the display stops cycling. By toggling the Resetbutton the test is now under manual control.To test the office link, short Tx to Rx and Tx to Rx.

5 Soak cycle. This provides a continuous cycle for preset systems. Any preset valve

connected to the meter will continuously cycle through a delivery sequence.Flag 23

This Flag is used as a test display where the batch display shows the current temperature.

Flag 30-37 (LINKED Flag 21 )

The meter calibration factors are entered here. Only those factors relating to the class selected underFlag 21 are available. These are indicated by an x in the Flag table (above).

Flag 40

Flag 40 is used to set the maximum flow rate for the system. In practice, this is linked to the metersize. The operator will be unable to enter a Figure that is greater than the maximum specified flowrate for the meter (e.g. 1500Lpm. for a AH single capsule meter). Once this flow rate is exceeded themeter will automatically shut down any valves and the error message too fast will be displayed.When setting Flag 21, it is essential that the maximum calibration flow rate is not set to a Figure higherthan Flag 40.

A setting of 0000 will disable this feature.

Flag 50

If the meter is to be used on products other than distillate an offset (providing a datum shift incalibration) may be entered as a viscosity correction. For most applications this figure is usually kept

at 0.00%. In some cases, where meters are mounted vertically, it may be necessary to enter a datumshift to assist calibration.


Flag 51 is used for temperature compensation and works in conjunction with Flag 52. When the tablesof Flag 52 are followed, the required reference temperature must be entered.

D1 0 Uncompensated volume.1 Temperature compensation to 15 C reference.2 Temperature compensation to 20

C reference.3 Temperature compensation to 31.5

D1 0 No preset control.1 Control by an Avery-Hardoll solenoid preset valve.2 A two stage valve control. The first stage will shut down the flow at a volume given by

Flag 13 (by-pass volume). This setting will allow a bypass volume of 0-990 litres. Thefigures given in Flag 13 will represent decalitres (the decimal point will not be displayed).

3 Preset valve control for systems fitted with slow acting valves. This is an ideal setting for8 valves. (Refer to the technical information sheet TIS 148).

4 This is a crude method of preset deliveries for vehicle systems.

D2 This is usually set to 0. If a minimum preset quantity is required to prevent small deliveriestaking place, this bit may be set to a Figure (0-9) representing the number of 100 litres.Example: Setting 2 would prevent deliveries of less than 200 litres.When used in conjunction with the large valve setting (D1=3), this provides a second stageshutdown flowrate. (Refer to the technical information sheet TIS 148).

D3 0 No interlock sensing.1 There are three interlock senses available (Earth connection, Overspill and loading Arm

position).

D5-6 This is used as a crude pump controlled preset. A two digit timer (in seconds) can beprogrammed to turn off the gantry pump from a no flow situation after a set delay. This willonly operate on preset systems where the Run button is pressed to initiate the start of delivery.


D1 0 This is the setting for vehicle use.1 Setting for a gantry system. The gantry pump is controlled (via SSR3) by the run button.

D2 0 This is used when Masterload is stand-alone ( local mode ) and not connected to anyexternal devices (e.g. Office).

1 This is the setting for systemmode if Masterload is intended to be connected to peripheralequipment (e.g. Office). Baud rate is 1200.2 If Masterload is intended to be switched between local and system modes (e.g. during a

communications fault) it is desirable that this rearrangement can be made via low security(i.e. without the need to break the security seal). Using this setting enables Flag 07 (D3) tobe set up. Baud rate is 1200.

3 As selection 1 with baud rate as 9600.4 As selection 2 with baud rate as 9600.5 Communication link to a local ticket printer (refer to end of section).

D3 (LINKED Flag 80 )SSR4 may be used to issue calibrated volume pulses to an external system. Usually this

output will provide pulses at the voltage level used by the system. Thus a 240 volt systemwill provide 240 volt pulses.

It is possible to feed different voltage levels via SSR4 by using the interlock input. It is notpossible to use this facility with additive injection in use (Flag 80).

0 No pulse output.1 A pulse output from SSR4 representing 1 pulse per unit of volume displayed.

(Pulse width 6mS).2 A pulse output from SSR4 representing 10 pulses per unit of volume displayed.

(Pulse width 600 S).3 A pulse output from SSR4 representing 1 pulse per 10 units displayed.

D4 Masterload has an in-built safety feature to warn the operator of leaks and to act as ananti-theft device. If a flow rate of less than 1% of the maximum flow rate (Flag 40) isdetected for more than 30 seconds, the message too slo will be displayed and any valves

will be shut. Once this is detected thesystemremains inoperative (i.e. no button response)for at least 1 minute.

0 Disable the low flow message.1 Enable the low flow message.

D5 This is used to establish the communication link from Masterload to an office or external

device.0 Data is sent from Masterload on request from the office.1 Data is sent from Masterload on a periodic basis (once every second).

D6 0 This is the setting for gantry use.1 For vehicle use only.

This is the delivery time out in seconds (typically 30 secs.). and regulates the time period after flowhas ceased before the preset valve is automatically shut off.

NOTE:

When the flag is set to 0, there is no time out.

Flag 90

Flag 90 is used to format the display. Display information has been split into two groups:

Prime Defines the standard display data.Secondary Defines extra data that is the available.Both Prime and Secondary data may be set to give:

Uncompensated VolumeCompensated VolumeWeight

If Flag 51 is set to 0, then the compensated volume will be the same as the uncompensated value.If set to display weight, the correct density must be entered via Flag 05 or by densitometer.Masterload will always use the value of Flag 05 even if Flag 54, D1=0.

D1 3 This format is useful for displaying volume and weight on the same display unit.The flow rate is given in US Gallons/min.

4 This mode is intended to display compensated and uncompensated volume (i.e. Nett andGross) on the same batch display. The Reset button is used to toggle between these twostates and a curser on the LCD display points to the appropriate Nett or Gross legend onthe dial mask.

Flag 99

Flag 99 is used to view details from previous transactions. This facility is generally known asTransaction Storage .

Masterload is capable of storing details from 40 transactions. This can be useful if running in systemmode and the controlling computer suffers some form of crash. Transactions can still proceed instand-alone (local) mode and details of past deliveries may be recalled using this facility.

Assessing Transaction Storagea) Press and hold the Reset button to gain entry to the passcode (refer to Chapter 2).b) Enter the passcode to gain access to the Set Up data..c) Select Flag 99.d) The display will show d-1 (the last recorded delivery) together with the delivery details:.
