2.1.1 Mechanical

The models having a stainless steel case are described as complying with IP67 and those with

a plastic case to IP41 of EN 60529.

2.1.1.1 The IP41 enclosure comprises of an upper and lower plastic moulding to

which are attached the printed circuit board and other mechanical components.

The main printed circuit board is attached to the rear face of the lower moulding and to

D-type connectors in such a way that the D-type socket fit into apertures in the interface plate.

The print head mechanism is attached to the printer assembly plate. The controller board is

mounted such that the component side faces away from the plate onto which it is mounted.

The display module is mounted on four pillars in the upper moulding.

The keyboard tails pass through slots in the exterior front face of the upper moulding, the

membrane assembly is self-adhesive and stuck into an aperture on the exterior front face of

the upper moulding.

2.1.1.2 The IP67 version has a stainless steel case which has a lid and base. The

transformer and printed circuit boards are fitted to an internal base plate which may be

removed from the outer base. The display and keyboard are mounted in the lid.

Cable entry to the indicator is via waterproof glands on the lower case assembly. The signal

cables utilise bayonet connectors to facilitate the removal of peripherals. Unused cable entries

have metal blanking plates. The weight input leads use the connectors furthest away from the

mains input lead.

The mains lead enters the case via a waterproof gland and sealing washers. This lead is not

fitted with a plug for safety reasons.

The lid assembly is secured to the lower case assembly by four screw locks. A self adhesive

gasket is attached to the inner face of the lid around the periphery of the keyboard to prevent

ingress of water.

2.1.2 Electrical

IP41 Versions

The mains power input is via an IEC socket with integral fuse and EMC filter. The live and

neutral connections from the output of the IEC connector are taken to the primary of the

transformer.

IP67 Versions

The mains power cable enters the machine via a waterproof gland with the live conductor

being connected to one side of the internal fuse holder whilst the neutral conductor is

connected to the EMC filter. The fused live conductor is also connected to the appropriate

terminal of the EMC filter. These conductors are in turn connected to the primary of the

mains transformer.

4

2.1.2.1 The power supply used in both versions is of the switched mode type and uses

a switching regulator operating as a fly-back converter in continuous mode.

The output from the secondary windings of the transformer is connected to the main board

and is full wave rectified. All voltages necessary for the unit are derived from the 27 volt dc

secondary.

The power supply is designed to cope with excessive currents and to detect power failure.

2.1.2.2 The digital micro-controller controls the functions of the indicator by means of

a program stored in the EPROM. Since the address space of this micro-controller is limited to

64-kbytes, the program area is arranged in banks which are segmented into 16-kbyte blocks

referred to as pages. The input and output devices are mapped into memory and selected by

one of the decode lines as required. All data transfer and micro-controller actions are

synchronised to the system clock generated by a crystal oscillator.

2.1.2.3 The non-volatile EEPROM is used to store calibration data that is recalled

when the indicator is switched on, a serial access device is used to increase security of the

data from corruption.

Serial data is transferred between the EEPROM and the micro-controller and synchronised to

the clock signal generated within the micro-controller.

2.1.2.4 The system clock oscillator is buffered to provide a clock signal to the

analogue-to-digital converter. Serial data is then transferred in and out of this converter and

synchronised by the clock signal.

The data conversion circuitry is based around a semi-conductor monolithic 20-bit converter,

which supports either 5-, 4-, or 3-pin interfacing.

This converter is operated in external dc excitation mode and communicates with the micro-

controller via a 5-wire serial bus. Neither the internal calibration systems nor the offset DAC

is used.

Whenever power is applied to the converter the device must be reset to a known condition

before correct operation can occur, the converter includes an internal power on reset function

that initialises the internal logic. The analogue input voltage from the load cell is applied to

the converter via a low pass filter and a capacitor which decouples any high frequency noise.

2.1.2.5 The auto zero tracking function automatically adjusts the zero offset of the

scale to compensate for small variations of readings from the unit. The function only operates

when the unit’s weight reading is within the gross zero division and, when the weight is

deemed steady according to the parameters entered in the service set up mode. The zero

tracker will only work within the configured balance range. Zero setting is limited to 4% of

the total capacity.

2.1.2.6 In order to prevent the weight display from flickering when the weight is right

on the edge of a division, the anti-flicker function will bias the weight upwards or downwards

by a maximum of ± 2/10 div to ensure a stable reading.

This function will only operate if the weight is deemed to be steady and will not be active

when the unit is at zero or full capacity.

5

2.1.2.7 There are two tare keys on the L226 and L225 which enable the use of semi-

automatic and preset tares.

Both allow the user to subtract a value from the current load on the load receptor, although

each one is entered separately.

Tares available are:

Preset

Semi-automatic

Retained

Cumulative and

Stored

2.1.3 Options printed circuit boards

There are two options printed circuit boards mounted directly above the main PCB.

The serial communications board provides facilities for one optically isolated RS232 serial

channel with RTS and CTS handshake lines and one optically isolated RS485 or RS422

receive and transmit channel.

The second board provides four optically isolated outputs and four optically isolated input

trips and one 4-20 mA current loop analogue output interface powered either from the

indicator or from an external current loop source.

2.1.4 The internal printer on the IP41 model uses a Citizen MD910 print head and a

CBM-909-2DNF controller board.

2.1.5 Sealing and identification

2.1.5.1 At least one of the case securing screws has a special head and is fitted with a

recessed washer to prevent ready removal without a special tool. This may be covered by an

inspector’s approval sticker where local regulations require it. Protection levels are described

in Section 2.7.

The load cell connector, on the stainless steel cased versions, is a shrouded moulding with a

tamper-resistant screw and cup. The plastic cased models have a wire seal across the long

screws on the load cell connector at the indicator.

Alternatively the combination of both indicator and load receptor(s) may be identified by

having suitable labels which bear a common serial or identification number.

2.1.5.2 Markings are positioned behind the keyboard and display overlay or are

affixed to the side of the instrument and include separate capacity and rating plates.

The capacity plate includes:

capacity,

interval,

model number and name.

6

The rating plate includes:

Maximum capacity (Max..)

Minimum capacity (Min..)

Scale interval (e= )

Accuracy classification (III)

Certification number

Manufacturer’s name and logo

Electrical data

Serial number

Model number

The location of markings on the front face is shown on a model L226 in Figure 2 and the

location of markings on the side of the instruments is shown in Figure 3 for the IP67

enclosures and Figure 4 for IP41 enclosures.

2.2 Weighing platform

The Avery H300 platform consists of a fabricated steel baseframe to which the Avery T101

load cell is bolted. A fabricated steel H-frame, with a reinforced centre area, is bolted to the

top of the load cell and a loose steel load receptor fits over this. Five stops are fitted to

prevent overloading of the load cell; one is directly under the load cell and the others between

the base and H-frames. A steel cover plate under the baseframe conceals the junction box. A

level-indicator is fitted to the baseframe and is visible without removing the cover. The level

is adjusted by means of four levelling feet below the baseframe. The platform dimensions are

500 mm x 550 mm.

2.3 Operation

The machine can be considered to operate in a number of modes described below:

Off mode

Weighing mode

Supervisor mode

Trips mode

Service mode

Filling mode

Packing run mode

Conversion factor mode

Type through mode

Product listing mode

Checkweighing mode

Counting mode

7

2.3.1 Off mode

There are three methods of entering the off mode:

If the scale has been inoperative for some time

If the standby key is depressed in any mode other than off mode

If the power fails

2.3.2 Weighing mode

There are four ways of entering weighing mode:

Pressing the standby key when the unit is in Off mode

Pressing the trips key when the unit is in Trips mode (models L115 and L116

only)

Exiting Service Set Up mode

Exiting Supervisor Set Up mode

The instrument will first perform a ‘self-test routine’ which includes checking the hardware

for the configured options. During this routine, if any error is detected in the hardware then

this error will be displayed in the form of an error message which can be cross referenced.

After ‘self-test’, the instrument will check its configuration to confirm what parameters are

required at power-up and will act on these parameters if it is in standby mode.

2.3.3 Supervisor mode

This mode is the subsection of the Service Set Up Mode in which only certain parts of the

instrument’s configuration, which do not effect its calibration or other key functions, may be

altered.

2.3.4 Trips Set Up mode

The trip outputs can be configured in Service set-up mode. The operation of the trips interface

for each different configuration is described in the users instructions.

2.3.5 Service Set Up mode

2.3.5.1 Entering. There are two methods of entering this mode:

If the following sequence occurs then the unit will enter Service Set Up mode.

(a) In any mode other than the service set up mode press the test key

(b) Whilst the display test is occurring, type in the password and the unit will enter

the service set up mode.

If the machine is configured to be totally secure, i.e. not allow any access to EEPROM data,

then a connection must be made on the main circuit board to override the security level. This

can only be achieved by a properly trained service engineer.

2.3.5.2 Exiting. Similarly there are two methods of exiting this mode:

2.3.5.2.1 For models L226, 225, 216 and 215, after entering new parameters. Depress

the “ESC” key and, following the display prompts, using the “↵” key to confirm acceptance

of information will return the instrument to the weighing mode.

8

For the L116 and 115, exiting the setting up mode is achieved by the following key sequence:

CE, ↵, 99, ↵, ↵, 99, ↵.

2.3.5.2.2 Depressing of the ‘Standby’ key, or allowing the auto shutdown condition to

be met or the power failing, will cause the unit to enter the ‘Off mode’.

2.3.6 Filling mode

Filling mode provides the operator with a display which will allow him to perform a filling

operation into a container on the load receptor. The display indicates numerically and

graphically what percentage of the filling operation has been completed. The filling operation

will work for both position and negative (emptying) weights.

Within filling mode, when the weight is such that the filling target has been reached, then the

filling display will flash, and, if configured in service mode, the bleeper will sound.

2.3.7 Packing run mode

The packing run option allows the operator to set up the L225/6 to perform a simple

automatic totalising and printing of a predetermined number of items. In use, an item is

placed on the load receptor. When the weight is deemed steady, the totals store is updated

with the net weight and a print-out is automatically initiated on any of the communications

channels configured for PRINT key operation. The serial string used is the configured string

for that serial channel. When the set number of transactions has occurred, a final printout of

the packing run is produced, and the totals stores and transaction counters used are flagged for

resetting. The final packing run string is configurable in Service set-up mode. The totals

stores used are the default stores if there is no PLU active; if a PLU is enabled then the totals

associated with that PLU are used for the packing run totalising.

Weights below the minimum packing run value will not cause the totalising/printing

operation to occur.

2.3.8 Conversion factor mode

The conversion factor option allows the operator to `scale’ the net weight by a user-entered

factor. The operator can enter the factor and select the required units which has been created

by the Supervisor previously.

The conversion factor must be configured to be limited to a maximum multiplier (or divider)

of 10; if the machine is so configured then the converted value will NOT be displayed on the

L225/6 but can appear on printouts.

2.3.9 Type through mode

Type-through mode allows the operator to use the alphanumeric keys to type in a text string,

which will then be printed out on the selected printer.

2.3.10 Product listing mode

Product listing mode allows the operator to perform a simple product listing/totalising

sequence. The facility operates in conjunction with the user fields to allow a list of items to be

printed, and a total of the items produced at the end of the listing sequence. The user fields

can be used for listing information, e.g. supplier, address, batch number, etc.

9

When product listing is active, pressing the Print key will not cause the L225/6 to prompt for

user field data entry; instead of this a description is required. If a PLU is active, then the

description associated with the PLU is used; if not then the operator is prompted to enter a

description.

2.3.11 The L226 and L225 incorporate certain battery backed totals stores for

management information. These totals can be updated automatically, if configured, or

manually by the use of the ‘ADD TO TOTALS’ and ‘SUBTRACT FROM TOTALS’ keys.

The totalising function can be used for the transaction of Sub Totals, Grand Totals, Trips

Totals and PLU Totals.

The PLU key enables the operator to display previously stored PLUs. A PLU can be enabled

either by entering a PLU number or by entering a part number associated with that PLU.

2.3.12 The Gross/Net key may be configured to toggle between gross and net

indications or to press and hold for the gross value.

2.4 Calibration

Calibration is only possible when the unit is in Service Set Up Mode and, as previously

described, this mode can be configured to be accessed only by authorised personnel. When in

Service Set Up Mode, user prompts guide the service engineer to the sequence required for

setting up the machine.

2.5 Counting mode

This mode allows the operator to configure the L215, L216, L225 and L226 to perform

counting operations. When the count is active the weight display is replaced by the count

display and the units icon changes to display the counting function.

Entry to the counting mode is achieved when the soft key labelled ‘COUNT’ is depressed.

Other soft keys enable use of various operations in the counting mode e.g.:

F1 for Sample counting

F2 for Piece Weight counting

F3 for Target counting and

F5 for updates on the status of the unit

If valid parameters are available from a previous counting operation, then these will be used

to provide a count display immediately. If no parameters are available, then the L226 and the

L225 will continue to display weight in the current units.

2.6 Checkweigher

The checkweigher option allows the operator to perform simple checkweighing, whereby the

display gives an indication of under tolerance, within tolerance and over tolerance. The L226

and the L225 can be configured in the Service Set Up mode in either of two ways:

the weight display is replaced with three large blocks indicating under, accept

or over or,

The weight display is reduced in size and small under, accept and over blocks

appear directly underneath it.

10

2.7 Safeguards and interlocks

Various levels of security are described in the manufacturer’s instructions. The highest level

is provided when an internal solder pad is open-circuit. Its location on the main printed circuit

board is shown in Figure 5. Lower levels of security become accessible by connecting the two

sides of the pad and entering a password.

2.7.1 Tare and balance are inhibited if motion is detected.

2.7.2 Security

The service engineer uses this option to assign levels of security for the L225 and L226

service set up variables.

Upon entry the display shows the message SET UP PROTECTION and the currently

configured option.

Possible levels of security are:

None - no security settings are configured; the service engineer may alter any

data within the set up mode

PROTECT CAL-INFO - set up information relating to the calibration of the

instrument may not be altered. Other machine parameters can be freely altered.

VIEW SET UP ONLY - no variables can be altered in the set up mode

DENY ACCESS - service mode is not accessible.

2.8 AUTHORISED ALTERNATIVES

L226 family will be used as the indicator only with the suffix “D” to identify the indicator

used.

Load Cell Emax Mounting Drawing VMin nmax

Avery T301 30000 kg 70714-342 Emax/9375 6000

Analogue-to-digital conversion is performed in the T301 load cells. The circuit contains a

programmable gain amplifier set to a gain of 100 and a 20 bit A/D converter and digital filter.

The effective sample rate of the A/D is 16 kHz.

Various internal registers exist to enable programming of gain, offsets and operating modes.

The processor writes to these registers only at power up and also reads the registers back so as

to ensure that the device is correctly programmed. The register values are factory set.

The load cell column gauges provide a signal which is suitably de-coupled before reaching

the A/D converter chip.

An A/D reference voltage is generated by dividing down the +/- 5 V excitation voltage using

precision resistors.

Provision is made in the T301s analogue-to-digital processing to compensate for changes in

temperature by using an integrating A/D converter controlled by the processor. The processor

uses a timer to provide both a constant ramp-up time and to measure the temperature

dependant ramp-down period.

The weight is passed onto two digital filters after being temperature compensated. After

filtering, the weight is converted from counts to divisions and also linearised in one function.

The formula is stored in EPROM but is copied into RAM at power-up. The weight is then

passed to a junction box. The junction box has a painted mild steel enclosure with cable entry

glands for load cell cables (maximum 8-off), indicator cable and mains supply cable. It has a

lid secured with four screws which gives access to the internal components.

Internally, the junction box contains two PCBs:

(i) Power supply PCB, part no. 71014-880

This contains a mains transformer, rectification and regulation circuitry to provide the +/- 9V

DC power supply to the connected T301 load cells. Connectors are provided on the PCB to

allow up to eight T301 load cells to be connected and for a cable to a Loadstar indicator to be

connected. The PCB also incorporates surge arresters and transorbs to protect the system

from damage in the event of high voltage surges due to lightening activity.

Mains power is supplied to this PCB via a mains filter which is located adjacent to the PCB.

17

(ii) T301 load cell scanning PCB, part no. 71014-875

This is a microprocessor based PCB with associated RAM, ROM, and EEPROM memory

and software. It is connected to the power supply PCB via a ribbon cable and its function is

to sequentially address the connected load cells to obtain weight values, apply corrections for

deadload, span, non-linearity and eccentric load conditions and to output a corrected total

load value to the connected Loadstar indicator. Corrections to the load cell weight values are

made in accordance with factors stored in the EEPROM memory at the time of system

calibration. The EEPROM checksum is validated at power up and the EEPROM contents are

hardware write-protected after calibration.

The scanning PCB also continuously monitors the status of the EEPROM and A-D converters

in each connected T301 load cell and flags potential error conditions to the connected

Loadstar indicator.

2.8.10.2 Having the limit of maximum capacity such that 6 kg ≤ maximum capacity ≤

200 000 kg for weighbridge applications, where the approved vmin and nmax figures for the

ticket issued.

(iv) Having the facility to summate the weight values from multiple platforms,

provided that the platforms have the same maximum capacities (Max) and

verification scale interval (e).

2.8.44 Having Class IIII, with single interval and n ≤ 1000.

2.8.45 Having the instrument modified as described below.

2.8.45.1 System description

2.8.45.1.1 Having a FIBC bag filling system mounted on a 1.5 m x 1.5 m H500 platform

as shown in Figure 6. The system capacity is 2000 kg by 0.5 kg.

2.8.45.1.2 The FIBC bag filler comprises a mainframe fabricated from rolled steel

sections and plate.

2.8.45.1.3 A fabricated carriage is suspended within the mainframe and supported by a

counterweight. The carriage runs within guide tracks on the mainframe. The carriage supports

the filling spout and bag holding forks.

2.8.45.1.4 A pneumatic cylinder, mounted in the mainframe, controls the movement of

the carriage/counterweight assembly.

2.8.45.1.5 The FIBC bag is attached to the filling spout by means of a manually operated

locking ring.

2.8.45.1.6 The bag filling system is mounted on and secured to the top plate of the H500

platform by 4 bolts.

2.8.45.1.7 The filling system incorporates the following controls:

(i) CYCLE START Starts the normal filling cycle.

(ii) HOLD CYCLE Pauses the normal filling cycle.

(iii) TOP UP Add to delivered weight if necessary.

(iv) ACCEPT WEIGHT Accepts final delivered weight, commands

indicator to print final weight, releases bag for

removal.

(v) SELECT Two position selector switch:-

MANUAL/AUTO Manual - allows manual carriage and feed

operation.

Auto - allows the normal filling cycle to operate.

25

(vi) SELECT CARRIAGE. Three position selector switch.

UP/DOWN Functions with manual selector to raise and

lower the carriage and forks.

(vii) MANUAL MAIN Functions with manual selector to open feed

FEED device to allow fast feed to clear product

remaining in the feed system.

(viii) ABORT CYCLE Aborts the filling cycle. Once operated a filling

cycle cannot be restarted. The part full bag must

be removed before a new cycle is started.

Functions as an emergency stop.

2.8.45.2 System operation

2.8.45.2.1 An empty pallet is placed on the platform. With the carriage in the lowered

start position an empty bag is placed on the pallet and the bag loops slid over the carriage

forks. The neck of the bag is clamped in position on the filling spout.

2.8.45.2.2 The start pushbutton is pressed causing the carriage pneumatics to operate

lifting the bag clear of the pallet.

2.8.45.2.3 The system causes the indicator to tare off the weight of the pallet and the bag.

2.8.45.2.4 The feed device above the filling machine opens allowing material to flow into

the bag. When the weight of the product in the bag exceeds that of the counterbalance weight

the bag slowly lowers onto the pallet. The counterweight keeps the bag in tension during the

remainder of the filling cycle.

2.8.45.2.5 When set point 1 is reached a slow fill is activated. Filling continues at the

slow fill rate until set point 2 is reached when the feed stops.

2.8.45.2.6 The operator reads the delivered weight displayed on the indicator. If

underweight, the operator presses the “Top-up” pushbutton, activating slow fill, until the

required weight is delivered.

2.8.45.2.7 When the delivered weight, displayed by the indicator, is acceptable, the

operator presses the “Accept Weight” pushbutton. The system issues a print command to the

indicator and cancels the tare.

2.8.45.2.8 The system activates the carriage pneumatics lowering the carriage forks to

release the tension on the bag loops. The bag neck clamp is released allowing the bag to be

removed from the platform.

2.8.45.3 Authorised alternatives

2.8.45.3.1 Having a powered roller conveyor mounted on the platform, inside the

mainframe, to allow transfer of the pallet and bag to a roller or belt conveyor system when the

filling cycle is complete (Figure 7).

2.8.45.3.2 Having a powered belt conveyor mounted on the platform, inside the

mainframe, to allow transfer of the FIBC bag to a roller or belt conveyor system when the

filling cycle is complete (Figure 8).

26

2.8.45.3.3 Having the standard spout with locking ring replaced with an inflatable spout

to provide a seal between the bag neck and the filling spout (Figure 9).

2.8.45.3.4 Having the standard spout with locking ring replaced with a pneumatic clamp

spout to clamp the bag neck to the filling spout (Figure 9).

2.8.45.3.5 Having a bag inflation blower fitted for use with FIBCs fitted with loose

polythene liners. In which case the carriage forks may be omitted and an additional control

added to facilitate bag inflation.

2.8.45.4 Recommended additional tests

2.8.45.4.1 Ensure that all connections to the FIBC filling system do not, and could not,

cause any interference that could affect the weighing result.

2.8.46 Having a weighbridge installation with up to 12 load cells:

The installation is arranged as two groups of six load cells, type 8701. The six load cells of

each group are connected to a Y101 corner unit, the two Y101 corner units are connected to

the indicator where the summation of the weight value is calculated and displayed.

2.8.47 Having the L116 indicator re-badged with the Salter Brecknell name and

designated the Dp 101.

2.8.48 Having the manufacturer designated as Berkel Prior.

3 TECHNICAL DATA

Accuracy Class III

Maximum capacity = Max = 60 kg

Minimum capacity = Min = 400 g

Verification scale interval = e = 20 g

Maximum tare effect = - Max.

The above data, other than the accuracy classification, may vary for the alternatives listed in

Section 2.8 to reflect the relevant capacities and verification intervals.

4 PERIPHERAL DEVICES AND INTERFACES

Having the indicator connected via a serial communications port to a printer which will be

used for tally roll record purposes and, via an opto-isolated communications port, to a

computer. In such cases a green `M’ sticker must be affixed to the tally roll printer and a red

`M’ sticker to the computer.

The computer may incorporate a VDU and associated keyboard. The VDU may be in the

form of a CRT, Dot Matrix, LCD or similar form of display as appropriate to the system.

A unique consecutive number generated by the indicator is associated with each weight sent

to the computer. Unique in this context means that it shall not be repeated within one year.

The consecutive number including, where relevant, the date can not easily be reset.

A number of weighing systems may be connected to a common computer in which case the

consecutive number must also identify the particular weighing system in use.

Data sent from the computer or associated keyboard to the indicator is limited to:

requests for data

print commands

data acknowledgement

entry of a tare

operation of set points

Commands for the above may be initiated but not acted upon while motion is detected. The

instrument must respond without noticeable delay when stable equilibrium is achieved.

A ticket must be produced for each weighing. First and second weights used to produce a

“NET” weight may both be recorded on a common ticket.

In cases where a number of similar items are assembled into lots, e.g. a pallet, then a

summary ticket may be printed with clear details of the individual items forming that load.

The ticket has all weight related data in characters not less than 2 mm high and without

slashed zeros, has the correct units of measurement, indicates the consecutive number of each

weighing, identifies the place of weighment, is clear and unambiguous and carries clearly and

prominently the statement: “A tally roll record of this weight is retained for 6 months”, or

suitable equivalent wording.

28

It is not possible to initiate a second printout for the same weighing operation, unless:

(1) the second ticket is clearly a duplicate of the first ticket e.g. multi-leaf with

different colours, headings or is marked duplicate, or

(2) the ticket is in the form of labels to be attached to the item being weighed.

When the ticket is attached securely to, and retained on, the item weighed, weight related data

produced by or from the computer carries a clear statement:

“A tally roll record of this weight is retained for 6 months and may be found

by reference to the weight ticket.”

Other data will be clearly separated from the weight data and where such data includes

conversion factors these will be stated, e.g. milk xxx kg/litre xxx litres.

Where a stored “weighed tare or first weight” is used the consecutive number of that weight

and the date of weighment are shown on the relevant documents.

The computer may have additional printer(s) or terminals connected to the system for other

purposes.

The computer may be connected to a further remote computer.

Disconnection of the tally roll power supply, data line or shortage of paper inhibits data

transmission to the computer.

Where weight information is sent to the computer solely to provide control of a process then

the consecutive number need not be generated provided the architecture of the circuit and

software is such that the information cannot be stored, printed or passed on to another

computer.

A VDU may be used to display weight only where it forms part of the text of a multi-line

display and the weight data are the same height as the text and the digits / figures are not

more than 6 mm in height.

The computer is not used to control functions affecting the operation of the weighing system

e.g., zero setting devices, barriers to control the position of a vehicle on a weighbridge etc.

All tickets and documents concerning weight data produced by or from the above system,

including remote computers, intended for purposes listed in Article 1.2(a) of the Directive

2009/23/EC are directly traceable to the tally-roll record which contains enough information

to allow cross-reference.

The ticket printer may be connected to the indicator directly in place of the tally roll printer in

which case:

(1) all relevant information (such as the unique consecutive number) is now

printed on the above ticket and the ticket shall be retained for a period of 6

months.

(2) data shall not be sent to the computer unless a ticket has been produced and

any weight related data produced by or from the computer shall carry a clear

statement: “The weight of these items may be verified by reference to the

relevant weight ticket”, or appropriate equivalent wording.

29

4.1 Having an Avery M209 peripheral device with integral data archiving facility.

The M209 is basically an Intel 386, 486 or ‘Pentium’ based PC mounted within a stainless

steel case. An LCD panel and keyboard are provided.

The stainless steel case is secured against unauthorised entry.

Weight data is securely stored in a separate partitioned area of the hard disk with sufficient

storage capacity for 2000 records a day for 6 months.

Weight data records may be viewed but cannot be altered. When the data storage area is full

the records will start again from the beginning, over-writing the previous records. At this time

the previous records are at least six months old.

This peripheral device may be used to replace a computer and associated tally record printer.

4.2 The non-automatic weighing instrument (NAWI) may be connected to any

peripheral device which is technically compatible and has a Test Certificate issued by a

Notified Body designated for EC Type Examination under Directive 90/384/EEC in any

member State and which meets the essential requirements of the Directive including the

relevant EMC requirements. Such peripherals bear a Green `M’ sticker.

However, simple recipient devices that:

- bear the CE mark for conformity to the EMC Directive 89/336/EEC;

- are not capable of transmitting any data or instructions into the NAWI other

than to release a printout or to check for correct data transmission;

- print or indicate weighing results and other data as received from the NAWI

without any modification or further processing; and

- comply with the applicable requirements of EN45501 i.e. 4.2, 4.4, 4.5, 4.6 and

4.7,

may be connected to a NAWI which transmits data in accordance with 5.3.6.3 of EN45501

without a Test Certificate having been issued. A printing device may print additional

information such as date or number, to identify the printed weighing result(s) or sets of

weighing results.

4.3 The weighing instrument may be connected to any of the following printers:

Epson TM290

Epson TM295

4.4 Having a Tulip type DC/DT 486 sx/dx computer to which one or more

weighing instruments can be connected. Each connected weighing instrument has its own

identifier which is also used to differentiate between the indelible weight records for each

instrument.

All legally relevant software is protected against intentional changes with common software

tools by the generation of a checksum during initial installation. The checksum is verified

internally every time ‘Windows’ is run. An unsuccessful checksum verification will cause

`Windows’ to terminate.

4.5 Having a computer or other logic device(s) connected to the indicator for

controlling the zero setting devices and optional devices used to control the position of

vehicles on a weighbridge for the purpose of providing driver operated weighbridge facilities.

In this case:

(i) A ticket is issued to the driver.

(ii) A weight indicating device is available to the driver.

(iii) Adequate instructions are clearly visible to the driver together with a contact

point in the event of any problems. Where the weight is below the minimum

load or above the capacity of the instrument a ticket indicating “Invalid

Weight”, or equivalent wording, is issued or printing is inhibited with

alternative instructions available to the driver.

Interlocks may be provided so that when a vehicle is not correctly positioned on the

weighbridge load receptor no ticket is issued.

If any weight data is passed to the computer then the computer linking is as described in

Section 4.

31

4.6 Having a Tulip type DS 5/xxx, DT 5/xxx, or DE 5/xxx computer to which one

or more weighing instruments can be connected. Each connected weighing instrument has its

own identifier which is also used to differentiate between the indelible weight records for

each instrument.
