1. INTRODUCTION This service manual covers the AMB scales model AMB50, 110, 210 and 310. The basic mechanics for the scales are similar to AFP/L scales, the major difference being the heating chamber, temperature sensors and drying functions. This manual describes the electronics and the software parameters to set the operating conditions and the procedures for calibration and linearity. As there have been a number of changes to the mechanics and software since the original AMB balances were introduced it is difficult to have an all inclusive manual. The basic procedures given will be the same regardless of the version of balance used however it will be necessary to treat each balance separately based on what is discovered about the balance during service. The balance is separated into 2 major areas. The base has the weighing mechanism and the electronics for the weighing functions. This includes the main microprocessor for the system and the display circuit board. The upper chamber has the weighing platform, heating elements to dry the sample and the electronics to control the heating lamps and power supplies. To solve problems it is necessary to determine the cause of any problem. In most cases the problems are related to: Weighing mechanism Damaged flexures

Stressed parts Dirt in the magnet

Software

Parameters need to be reset Upgrade software to solve program errors.

Heating System faults Lamps burned out Temperature sensor damaged Parameters lost from memory Lamp control circuits damaged

Electronic problems Parts failure on one of the circuit boards

3. FUNCTIONAL TESTS To test the balance to determine if the weighing section is working OK it is necessary to test it as a standard balance. The basic tests are repeatability, linearity and off center loading. If necessary calibrate the balance.

3.1 CALIBRATION PROCEDURE Allow the balance to warm up for the initial warm-up period before calibrating. Have ready a suitable calibration weight, it is suggested it should be Class F2 or better. The balances use the following calibration weights: AMB 50 50g weight AMB 110 100g weight AMB 210 200g weight AMB 310 200g weight Press the [Tare] key. The display will show

Press the [Func] key while the bars are displayed. . When you press the [Func] key, the display will show the following messages: Press the [Tare] to skip calibration. Or wait for calibration to proceed. Calibration of zero point - the weighing pan must be empty. Place the calibration weight on the pan, 50g, 100g or 200g as requested on the display. Calibration is being executed (please wait).

Remove the calibration weight.

Calibration is finished. Place the calibration weight on the pan to verify the value displayed. If the displayed value is not correct then repeat the calibration procedure.

3.2 REPEATABILITY Place a mass equal to about 1/3 to 2/3 capacity on the pan a number of times. The balance should repeat the reading within 0.002g.

3.3 LINEARITY Have 2 masses each about 1/3 to ½ the balance capacity. Identify one mass as Mass A and the other as Mass B. Zero the display then place mass A on the platform, note the reading. Remove mass A and place mass B on the platform, press [Tare] to zero the display. Place mass A on with Mass B, the value of Mass A will be shown and should agree with the first reading, ±0.002g.

3.4 OFF CENTRE LOADING Zero the display with nothing on the pan. Place a mass about 1/3 to ½ capacity at the front, right, left and rear sides of the pan, ½ of the way out from the centre. The readings should agree within 0.005g. If these tests are acceptable then the weighing mechanism is working OK. If there is a problem with these tests then the mechanics for the weighing mechanism must be repaired before any other test can be done.

3.5 DRYING TEST To test the balance is drying properly it is necessary to have 2 steel or brass weights of about 5 to 10 grams. Set the parameters for the balance to Mode 1, determine %moisture, 50ºC, 10 seconds strobe time. Weigh both weights on the scale. Zero the scale and then put both weights on the pan and start the test.


6

After the test is started remove one weight. The scale will compute the % moisture- % m = 100 X Mass of removed weight / total mass For example, if a 5 gram and a 10 gram weight were used and the 5 gram weight were removed after the test starts then the %moisture is- %m = 100 X 5g/15g = 33.33% After about 2 minutes the scale should stop automatically with the % moisture displayed. If the %moisture calculation is wrong then it is necessary to determine if the balance drifted or another problem was apparent. Press [Tare] to view the weight remaining on the pan. It should match the original value for the weight ±0.002g. If the displayed value is different then test again to search for drifting results from the balance. Test again at high temperatures to watch for drifting that may be worse with the higher temperature. For a long term test it is possible to select mode 7 then set the maximum time for the test. It is not uncommon for high temperatures to cause some drift in the balance. An acceptable limit is 0.010g over an hour at 150ºC. If the mechanics drift too much then the source of the drift must be investigated. It is usually due to stresses in the flexures.

4. OPERATING VOLTAGE The AMB can be set to operate at either 110 volts AC or 230 volts AC by making changes to the primary coils of the power transformer and changing the lamp supply from the control PCB located in the rear of the balance. On models with 599811.PCB, the primary transformer coils and lamp supply wires are soldered in parallel for 110 volts mains power or in series for 230 volts operation. If the 590104.PCB is fitted then the unit can be set to run at 110 or 230 volts AC by the repositioning of some links which are fitted into screw terminals located around the power transformer. To set at 230 volts AC, only the top link is fitted into the screw terminal which is marked with a solid line. The lamps are wired in parallel but a diode is fitted as standard on the lamp supply voltage to reduce it by half. To set the AMB to 110 volts AC the top transformer link must be removed then the centre and lower links must be fitted. These are marked with a dashed line. A link must also be added to a third pair of terminals to bypass the diode in the lamp supply which allows the lamps to run at the same power without the need to rewire. Please ensure that this work is verified before the main supply is switched on to avoid permanent damage to the power supply components. If wired correctly the resistance across the mains input connector with the power switch set to on should be: Approximately 500 Ohms if set for 230 volts AC operation. Approximately 125 Ohms if set for 110 volts AC operation.

4.1 HALOGEN LAMPS The lamps in the standard AMB are: 200 watt, 220/240Vac Tungsten Halogen lamps The high temperature versions use: 300 watt, 220/240Vac Tungsten Halogen lamps The 220/240 lamps are similar in appearance and size to the security lights listed in many catalogues. It is very important that 500 watt lamps are not used. 500 watt lamps are the ones normally used in security products. Do not touch the glass of the lamps with bare fingers as the oils in the fingers can degrade the glass when the lamps are hot.

5. MECHANICS The AMB balances use a mechanical design similar to the AFP balances. Please refer to the AFP Service Manual for a detailed description. It uses a force restoration mechanics including the following major sub-assemblies: Magnet Assembly Horizontal Parallelogram Coil beam assembly Vertical Force system The basic function of the mechanics described below. The unknown weight is placed upon the pan. This will transfer a force through the vertical system connected to the parallelogram to the coil beam assembly. The coil beam is a fulcrum with a force due to the weight on one end and a force generated by a coil suspended in a magnetic field at the opposite end. The electronics associated with this system consist of an optical position sensor, amplifiers for position error signal and an amplifier to drive current through the coil. The position sensor is designed within a feedback loop so that only a current sufficient to hold the coil beam at a null position is passing through the coil. When a weight is added to the pan this balance is upset and the coil beam will attempt to move away from the null position. The position sensor detects this movement and forces a current to flow through the coil to restore the coil beam to the null position. The current also is flowing through a precision resistor to generate a voltage. This voltage will vary as the weight on the pan changes. The voltage is amplified, filtered and sent to an A/D converter. The ADC changes the analogue voltage to a digital representation that can be used in the microprocessor. The microprocessor changes the values for displaying the weight, keeps track of zero and tare values and does all the other necessary work to keep the system running. In general the circuit boards are not user serviceable. If you require more information about the circuit boards contact Adam Equipment. The mechanics can be serviced by a technician that has been trained on this or other force restoration balances.

The normal service for the mechanics is to replace broken or bent flexures. This process is relatively easy but alignment of the flexures can be important for good repeatability and linearity. There are not any special tools or alignment fixtures used with these mechanics. It is best to try to maintain positions and symmetrical alignment. Extra care is required to make sure the coil is centred in the magnet assembly to avoid friction and ensure that the vertical flexures are not twisted or at an angle. 5.1 MECHANICAL ADJUSTMENTS

A BA B A B

5.2 OFF CENTRE LOADING ADJUSTMENT The adjustment of the mechanics or off centre loading can be done after the cover is removed from the balance. Remove the screws in the top of the cover to gain access. This gives access to the mechanical chamber. Using the attached figure (page 4) it is necessary to change the screws to make the readings of the weight equal as it is moved around the pan. The weight should be 1/2 capacity of the balance. The weights should be positioned at 1/2 the pan radius. The readings should match within 4 counts. Recheck linearity and calibration after adjustment.

6. MECHANICAL PROBLEMS Most mechanical problems are either due to improperly adjusted counter-weights, damaged flexures or friction in the mechanical system. The following is general guide about the repair of the mechanical system and important points to consider during repair or adjustments.

6.1 CENTRE OF GRAVITY ADJUSTMENT There are 2 types of counter-weights. The first one moves up and down. This weight is used to set the centre of gravity so that when the front or rear of the balance is raised by a small amount, the displayed weight changes as little as possible. To adjust this weight: Place a 1/2 capacity weight on the pan and note the reading. Raise the front or back of the balance by 1mm, tare the balance and place the weight back on the pan. Adjust the center of gravity weight so the reading due to the movement of the front or rear of the balance, is within 10 divisions of the level position.

6.2 ZERO WEIGHT A/D VALUE The second type of counter weights move along the horizontal axis. These weights are used to set the zero value for the A/D converter. The weights are adjusted so that the 0 weight voltage to the A/D converter (as measured at the test points AGND and Ain+1 next to the A/D) is set to the required level to enable the balance to zero. The count value to the A/D converter can be seen using the service menu, codes 001948 and 849100 if a volt meter is not available. This can be observed when setting the parameters as the “��” parameter. The value for the no weight condition is dependent upon the model tested and the revision of software used, (usually 2000-3000). To set this parameter, first make sure the pan is empty. Then adjust the horizontal counter weights so that the voltage at the test point is at the required level with no load and increases when more weight is added until full capacity is reached. At no point should the display show “��” unless the balance is overloaded. If this happens then the zero voltage can be reduced or sense resistors may have to be changed.


11

6.3 FRICTION IN THE MECHANICS Friction can cause non-repeatability of the readings. The most likely positions for friction are: Overload Stops Make sure they are free to move over the

normal operating range of the balance. Dirt in the magnet This necessitates a complete rebuild of

the system. Do not attempt if you are not certain of your ability to finish.

Rubbing wires, hair, etc. Only very careful observation can find this type of friction.

Loose Hardware Tighten all screws holding flexures. Be careful not to bend or twist a flexure.

6.4 FLEXURE DAMAGE Flexure damage can cause poor repeatability, stresses that affect the “��” value, non-linearity and poor off center loading. If the damage is severe the balance may not work at all. If damage can be seen it is necessary to replace the flexure. A bent or damaged flexure cannot be repaired by any method except replacing the flexure. Flexure damage can usually be seen a bent thin section, twist or in the most severe case the flexure will be broken. It is also possible that a stress in the flexures can cause repeatability or linearity problems. In this case it is usually not possible to see any damage. It is possible to relieve the stress by loosening the screws holding a flexure one at a time.

6.5 FLEXURE REPLACEMENT Often it is possible to replace one flexure without completely disassembling the mechanics. It is only necessary to remove the screws holding the damaged flexure. However it is very common that flexures are damaged in pairs or in the worse case all flexures in the mechanics can be bent. To replace flexures it is first necessary to identify the types of flexures used. As the balances have been improved the flexure design has had a number of detail changes.


12

To identify the flexures used refer to the flexure identification chart attached. This chart list the flexures used and the application the flexures were used in. Comparing the drawings with the flexures in the balance being repaired will identify the flexures to be used. To replace a single damaged flexure simply remove the screws securing the flexure and replace the flexure with a new one. Be very careful when securing the new flexure that it is not twisted, bent or stressed. After the flexure has been installed relieve any built up stress in the other flexures by slightly loosening the screws holding the flexures one by one. If more than one flexure is being replaced it will be necessary to install the new flexures but not tighten all the screws. The alignment of the flexures to each other and to the base is critical. However there are no tools or other mechanical aids to help the alignment. All vertical flexures should be aligned vertically to the base and to each other. The top and bottom edges of the coil flexures should be aligned horizontally so the thinnest sections are aligned. The longer vertical flexure should be vertical right to left and also front to back. A misalignment of this flexure is one of the main causes for poor linearity. The horizontal flexures need to be aligned so the thin areas are parallel and in proper alignment. The vertical flexure is then adjusted to make the horizontal beam assemblies parallel to the base. After flexure replacement it may be necessary to realign the coil inside the magnet. The coil should be centred in the air gap of the magnet. Also the overload stops should be checked to make certain the beams all have free movement. After flexure replacement it may be necessary to reset the “��” value for the A/D readings with zero weight on the pan. Also it will be necessary to reset the Off Center Loading when ever a flexure has been changed. It is usually not necessary to reset the temperature compensation.

7. PARAMETERS The details of the parameters given below are based on the software version PAS 12. Other versions of the software may have slightly different parameters or the order of the parameters may be different. Refer to the version closest to the one identified on the screen of the balance. Details of the additional information found in PAS 16E are attached (see 7.8). The parameters for the AMB Balance are set using a menu structure accessible from the keypad. There are 3 menus available. The first is used to set the basic operating conditions and is usually used only for new balances or balances that will not operate enough to show a weight value. The second menu is similar to the first except it allows you to view and modify parameters without starting over. Use this menu to recalibrate the temperature sensor. This menu is entered using the code number 8491. The third menu is entered using the code number 1948. This menu allows you to set the temperature compensation for the balance, not the temperature sensor calibration. This menu can only be accessed while the balance is operating by entering a password (001948) in response to a prompt on the display.

7.1 INITIAL PARAMETERS With the power disconnected press the [Print] and [Tare] key together then switch the power on.

The display will show “��”. Press the [Print] key to continue. If you press the [Tare] key, “��” will be displayed to tell you that you will reset the temperature coefficient if you continue. Press [Tare] a second time to return to “��”.

Display will show “ ��” This sets the default baud rate to 4800 baud. Press the [��] key to change to the other baud rates: Press the [Func] key to continue.

1=300 baud 4= 2400 baud

2= 600 baud 5= 4800 baud (default) 3= 1200 baud 6= 9600 baud

Display will show “��”, number of divisions

Enter the maximum value for the scale plus over-range using the arrow keys, and the [Func] key. [��] will select a digit, the [��] will increment the digit selected and the [Func] key will advance to the next parameter. Use the menus provided to determine the values to be entered for all parameters.

Display will show “��”, the value for the calibration weight.

Enter the value for the calibration weight as shown in the menu drawings using the same keys as before.

The display will then show “��” Temperature Sensor Calibration. Place a temperature sensor on the weighing platform before starting the procedure.

A> Press the [Func] key to show the value of the current ambient temperature at the pan, if other than 20ºC enter the new value using the arrow keys.

B> Press the [Func] key to show a value for the A/D converter from the temperature sensor. Normally this value is approximately 4000 at 20ºC.

C> Press the [Func] key to initiate the temperature test. The heaters will turn on at ½ the power and continue to run. Leave the scale to become stable at the high temperature. The scale must be left for about 15 minutes to allow the temperature to become stable.

D> Record the temperature at the pan, usually about 80ºC. E> Press the [Func] key, the display will show “��”. F> Immediately open the door and then enter the measured temperature

plus 2ºC. So if the chamber was 79ºC enter the value 81. G> Remove the temperature sensor. H> Press the [Func] key to continue.

The display will show “��”, the number of divisions from the A/D converter.

After checking the A/D value from no load (about 3000) to full capacity (up to 500,000 divisions), press the F key to proceed to the calibration section. The scale will instruct you to place a mass equal to full capacity on the pan by showing “��” where the xxx is the value of the weight. The scale will then instruct you to place a mass equal to ½ of the capacity on the pan by showing “��” where the xxx is the value of the weight. When the scale displays “��” remove all weight.


15

The scale will instruct you to place a mass equal to the calibration weight value on the pan by showing “��” the “��” where the xxx is the value of the weight. Place the weight on the pan and remove it when the scale shows “��”.

7.2 SERVICE MENU WITH 8491 CODE The Service menu will allow you to view and modify parameters as found in the initial menu. Use this menu to recalibrate the temperature sensor. To enter the service menu using code 8491 press the [Tare] key. When the bars are displayed press [Tare] and [Print] together. Using the arrow keys enter the code number 00849. Then press the [Func] key. A menu similar to the initial parameter setting menu will begin. Except in this menu the last values entered will be displayed and can be accepted without changes by pressing the [Func] key. Complete this menu as described previously.

7.3 SERVICE MENU WITH 1948 CODE This service menu will allow you to reset the temperature compensation of the balance. This is not the temperature sensor calibration. The balance temperature compensation should only be done if there has been a problem with the balance drifting badly during a drying test. To enter the service menu using code 1948 press the [Tare] key. When the bars are displayed press [Tare] and [Print] together. Using the arrow keys enter the code number 001948. Then press the [Func] key. A menu will start by showing the A/D counts as described for the “��” parameter. Press the [Func] key to continue. “�� ” begins the calibration program. When “�� ” is displayed it is possible to reset the temperature compensation of the balance. If not done properly the balance will drift badly when the temperature changes. Press the [Func] key to skip temperature compensation. Press [Print] to set temperature calibration to zero. Press [Tare] to begin temperature compensation. After pressing [Print] or [Tare] a warning message “��” will be shown. Press [Print] to continue or [Tare] to abort.


16

7.4 TEMPERATURE CORRECTION If it is necessary to correct the temperature compensation it will be necessary to have a space the balance can be tested where the temperature can be varied from ambient to 10ºC above ambient, i.e. from 20ºC to 30ºC. Begin by leaving the balance to operate at 20ºC for a minimum of 3 hours. Begin the SERVICE PARAMETER PROCEDURE as above. IMPORTANT It is possible to destroy data stored in memory using this procedure. Proceed only if you are certain that you wish to change the temperature compensation values. When “�� ” is displayed you have 3 options.

Press the [Func] key to set all temperature values to zero. Press [Tare] to set new temperature values. Press [Cal] to do a normal calibration without effecting temperature values.

7.5 TO RESET TEMPERATURE CORRECTION TO ZERO To set the parameters to zero press [Print]. A warning message is displayed “��”. Press [Tare] to abort the test or Press [Print]. Load the calibration weight when “��” is displayed. Remove the weight when “��” is displayed. The scale will now return to normal operation displaying “��” again.

7.6 SETTING TEMPERATURE CORRECTION VALUES To set the parameters press [Tare]. A warning message is displayed “��”. Press [Tare] to abort the test or Press [Print]. Load the calibration weight when “��” is displayed. Remove the weight when “��” is displayed. The scale will now return to normal operation displaying “��” again. Raise the temperature to 10ºC above the first temperature and leave the balance to operate for a minimum of 3 hours. After the soak time press the [Func] key to continue. Load the same calibration weight when “��” is displayed. Remove the weight when “��” is displayed. The display will return to the normal operation. It would be wise to measure the calibration weight on the balance and then return the temperature to ambient and let the balance rest for at least 3 hours. Weight the calibration weight again. The values should agree within 15 divisions.


17

7.7 PROCEDURE FOR SETTING TEMP. SENSOR CALIBRATION The following requires a sensor for measuring the pan temperature during the test. Refer to the Service Parameter menu for the AMB 110/210 for further details of the test. I> Have balance operating in the normal weighing mode. J> Press [Tare] and then press [Print] and [Tare] together. The display will ask

for a code number “��”. K> Using the right arrow and up arrow keys enter the code number “�� ” L> Press the [Func] key. M> Display will show “ ��”, press the [Func] key to advance to--- N> Display will show the value for the divisions, either 110090 or 210090. Press

the [Func] key to advance to – O> Display showing the value for the calibration weight, either 100000 or 200000.

Press the [Func] key to advance to --- P> Display shows “��” the temperature sensor setting program. Q> Press the [Func] key to show the value of the current ambient temperature at

the pan. if other than 20ºC enter the new value using the arrow keys. R> Press the [Func] key to show a value for the A/D converter from the

temperature sensor. Normally this value is approximately 4000 at 20ºC. S> Press the [Func] key to initiate the temperature test. The heaters will turn on

at ½ the power and continue to run. Leave the scale to become stable at the high temperature. The scale must be left for about 15 minutes to allow the temperature to become stable.

T> Record the temperature at the pan, usually about 80ºC. U> Press the [Func] key, the display will show “Open”. V> Immediately open the door and then enter the measured temperature plus

2ºC. So if the chamber was 79ºC enter the value 81. W> Remove the thermometer from the pan. X> Press the [Func] key to continue. Y> The display will show “��” then a value for the weighing A/D converter.

Normally about 5000 to 8000 with no load on the pan. Z> Press [Func] to continue. The scale will ask for a weight equal to ½ the scale

capacity (either 55g or 105g) to be loaded then removed. AA> The scale will then ask for a weight equal to scale capacity to be loaded then

taken off. The will ask for the calibration weight to be loaded then removed after calibration.

BB> The scale will return to normal. CC> Try running a sample test with the AMB scale using weights. The

temperature in the chamber should closely match the temperature measured by the sensor mounted on the pan.

7.8 CHANGES IN SOFTWARE VERSION- PAS 16E If the AMB Balance is supplied with PAS 16E version, refer to the procedure given below for setting up the following parameters. 7.8.1 Changing Languages This is a new feature available in PAS 16E Version only. To use this feature follow the procedure given below- Press the power supply switch to turn the balance on. The balance starts up by selecting the language last used. To change the language setting, switch the balance to OFF and then ON again. It displays “�!�"�”- the software version, followed by “��!�” for a few seconds. Press the [Start] key once “��!�” is being displayed. Either “��” for English or “��” for German will appear. Use the [��] key to change between the languages. Use the [Func] key to accept the setting. Next “��#�” will appear on the display screen. Use the [Tare] key to enter the setting. The balance will run through a “��!�” mode for few seconds. “��” will appear on the display.


19

7.8.2 Temperature Calibration (as per PAS 16E) (For PAS 12, to set up this parameter refer to the previous section no. 7.7) The temperature can be calibrated, when the balance is in the normal weighing mode. Through the circular opening on the top, insert the temperature sensor close to the weighing pan. Press [Tare], followed by pressing the [Print] and the [Tare] key simultaneously. On the display, a request for “codE” will be seen. Enter the correct code (“2003“) by using the arrow keys. Use [��] for numerical entry from 0 to 9 and use [��] for changing the display point. Press [Func] key for setting the programme. “St_tE” will be displayed. To check the temperature inside the weighing region, press [Func] again. The arrow keys should be used to change the temperature if is not correct. Press the [Func] key again. If 20 degree C is entered, a number close to 4000 will appear on the screen. The [Func] key is pressed again to start the Temperature Calibration. The balance will now heat up to 50% of its total power. Note: For stable result, the balance should not be moved for about 15 minutes. The temperature will be close to 80 degrees C in the weighing region. Press [Func] key. On the screen “��” will be displayed. The thermometer can be removed now. 2 degree must be added to every temperature value. For instance, if the thermometer shows 79 degree, another 2 degree should be added to enter a value of 81 degrees centigrade. The temperature calibration process is completed now.

AMB VOLTAGE CHANGE On later versions of the AMB balance a new power supply circuit board was used (type 5901xx) that allows changing the mains power supply to or from 115VAC to 230VAC using jumpers. To change the AMB Moisture Balance from 115V to 230V or 230V to 115V requires the user to change jumpers on the power supply circuit board. The Procedure follows as below. IMPORTANT SAFETY NOTE: Potentially Dangerous Voltages are used within the AMB Balances. The Unit must be isolated from the mains power supply before any work is done within the balances. 1. Unplug the balance from the mains power supply. 2. Unscrew the cover of the rear panel to gain access to the power supply circuit board. 3. Note the location of the jumpers required for operation at the voltage to be used.

115VAC ±10% 230VAC ±10%

Jumper 3 places in total Jumper 1 place

4. Place jumpers in the terminal blocks as shown in the accompanying drawings. 5. Replace the cover before applying power to the balance.
