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 the 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.

8

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

(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 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. 3.6 Having an Avery Y805 Trips Unit. The Y805 is used to interface Trips facilities to the E11xx series of indicators between opto-isolated outputs and high AC/DC loads. The unit has up to four input and four output modules which can be individually configured for site applications. 3.7 Having an overhead track weighing device.

The carriage supports the filling spout and bag holding forks. 3.23.1.4 A pneumatic cylinder, mounted in the mainframe, controls the movement of the carriage/counterweight assembly. 3.23.1.5 The FIBC bag is attached to the filling spout by means of a manually operated locking ring. 3.23.1.6 The bag filling system is mounted on and secured to the top plate of the H500 platform by 4 bolts. 3.23.1.7 The filling system incorporates the following controls: (i) CYCLE START Starts the normal filling cycle. (ii) HOLD CYCLE Pauses the normal filling cycle

12

(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

MANUAL/AUTO Two position selector switch: Manual - allows manual carriage and feed operation. Auto - allows the normal filling cycle to operate.

(vi) SELECT CARRIAGE.

UP/DOWN Three position selector switch. Functions with manual selector to raise and lower the carriage and forks.

(vii) MANUAL MAIN

FEED Functions with manual selector to open 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.

3.23.2 System operation 3.23.2.1 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. 3.23.2.2 The start pushbutton is pressed causing the carriage pneumatics to operate lifting the bag clear of the pallet. 3.23.2.3 The system causes the indicator to tare off the weight of the pallet and the bag. 3.23.2.4 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. 3.23.2.5 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. 3.23.2.6 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. 3.23.2.7 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. 3.23.2.8 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.

4 PERIPHERAL DEVICES 4.1 The weighing system may be connected to any peripheral devices that have been issued with a test certificate by a Notified Body responsible for type approval under Directive 90/384/EEC in any Member State and bears the CE marking of conformity to the relevant directives; or Peripheral devices without a test certificate under the following conditions:

− it bears the CE marking for conformity to the EMC Directive 89/336/EEC;

− it is not capable of transmitting any data or instruction into the weighing instrument, other than to release a printout, checking for correct data transmission or validation;

− it prints weighing results and other data as received from the weighing instrument without any modification or further processing;

− it complies with the applicable requirements of EN45501, i.e. 4.2, 4.4, 4.6 and 4.7.

4.2 Data storage device (DSD) A data storage device (DSD) having a Test Certificate (TC) may be connected to The weighing system if at conformity assessment for putting into service for an Article 1.2(a) application, it is checked that the requirements 6.1, 6.2, 6.4, 6.5 and 6.6 of WELMEC 2.5, Issue 2, 2000 are met. The DSD must have sufficient capacity to meet national requirements and the needs of the user. 4.3 Internal DSD (electronic tallyroll) The “SRAM” expansion board may be used to store data for each transaction and shall include the date, time, transaction ID and the net weight. There is storage capacity to hold a minimum of 4 months data (72,000-transaction records @ 600 records/day for 120 days).

For each trade weight that is taken. The following is recorded:

• conseq. no, plus scale id (scales 1 – 8)

• weight, plus units of weight, plus g/t/n identification

• time and date

The conseq no is normally a 6 digit numeric code starting at 000001 and rolling around to start again after 999999. This is allocated to each trade weight by the indicator. The load receptor ID is stored in the tally memory and is included in the information printed on tickets or sent to PCs. The user is able to print the transaction log either in full or in part starting from a particular transaction ID.

The markings and inscriptions shall fulfil the requirements of Paragraph 1 of Annex IV of the Directive 90/384/EEC. 6.2 Access to the configuration and calibration facility is password protected as detailed in GB-1162. Alternatively, access can be via a push button located on the main PCB which is accessed by removing the front cover of the enclosure. The enclosure can be sealed using a wire and lead seal. N.B. only one of these methods will be present on an instrument. Components that may not be dismantled or adjusted by the user, and load cell junction boxes where applicable, will be secured by either a wire and lead seal or tamper evident label and securing mark. The securing mark may be either:

− a mark of the manufacturer and/or manufacturer’s representative, or

− an official mark of a verification officer.

16

7 ALTERNATIVES 7.1 The indicator may bear the following alternative manufacturers name and model:

− Salter Brecknell Dp11xx

7.2 The indicator may be mounted on a simple fold away stand, a swivel mounted stand or an extended stand for wall mounting applications. 7.3 Having the model E11xx replaced by the model E12xx as described in Test Certificate No. GB-1170. 7.3.1 The E12xx series may be used for “direct sales to the public” if the pre-set tare device and “Select” function key are inactive. 7.4 Having an alternative software version (“768C App Basic” and "V1.4.12 axleLog") which permits the instrument to be connected to a PC and set into a "non-approved" mode for dynamic axle weighing. The indicator weight display will be blanked and the display will indicate "non-approved mode" when the instrument is in the non-approved axle weighing mode. The PC is used to switch between the approved NAWI mode and the non-approved mode. If the PC is not present the indicator cannot be switched into the non-approved mode. If the indicator has been switched in to the non-approved mode, and the PC is disconnected while the system is powered, the indicator will continue to display "non-approved mode", and indicator weight display will remain blanked. When re-powered without the PC connected, the instrument will always default to the approved NAWI mode.

7.5 The Avery 8701 load cell approved under this type approval certificate is technically compatible and freely interchangeable with the Avery T302, T302i and T302x load cells. Any weighing instrument verified under this approval may incorporate a mix of 8701, T302, T302i and T302x load cells. 7.6 Having the E11xx or E12xx series indicator and label printer connected to a PW100 weigh price labelling system. The instrument has been configured to function as a manual weigh-price labeller where the operator places the item on the load receptor, the instrument determines stability and prints a label automatically, and the operator then takes the label, removes the item, and affixes the label to the product. 7.7 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.

17

7.8 Having an application where there are two computers connected to the indicator serial ports, Com1 and Com2 respectively. The in-built trips functionality is configured to link both Com1 and Com2 to trigger Com3. Com3 is in turn linked to the internal DSD (electronic tallyroll). Note: In this configuration, an “SRAM” expansion board must be fitted for the DSD functionality, and a digital expansion board must be fitted to provide two extra serial ports in addition to the single port provided as standard by the indicator. In this configuration, the system works as follows:

(i) A PC requests a weight on Com1 (or Com2).

(ii) The Indicator sends the current weight with the current consecutive (Conseq) number to the PC and then increments the conseq number.

(iii) The Indicator ‘Alarms’ function then triggers an output on Com3. This output goes nowhere but results in the current weight being sent to the archive store with the current Conseq number (which is now +1 from the number sent to the PC).

(iv) The Conseq number is then incremented again.

The result is that the archive store (DSD) always holds a Conseq number which is one greater (+1) than the Conseq number sent to the PC. Therefore if the PC records a weight against Conseq number 1 then the corresponding Conseq number would be 2 in the archive store, etc. This offset of 1 in the Conseq numbers must therefore always be taken into account when comparing the recorded data on the PC to the corresponding record in the DSD. Records should be clearly marked to warn of this offset to avoid any potential confusion. The table below illustrates the sequence:-

Sequence Indicator Conseq number

Conseq number sent to PC

Conseq number sent to internal DSD

First Weight sent to PC

1 1 -

Indicator advances Conseq number

2 - -

Com3 triggers First Weight to be stored in DSD

2 - 2


3 - -

Second Weight sent to PC

3 3 -


4 - -

Com3 triggers second weight to be stored in DSD

4 - 4
