3 Practical Use The CC...-L / CCE..-L controller regulates the load alternator function sequences as well as the collection and evaluation of measured data. The individual values measured are output automatically to the built-in printer with the date and time of measurement and the calculated results. A modern, touch-screen display shows all function sequences and also serves as the user interface for operating the controller. User guidance prompts in plain English will guide you through the simple operation of the device. You can choose the following languages: - German - English - Spanish - French All of the function sequences are displayed and can be activated by pressing the corresponding field on the right hand side of the touch screen e. g. The number in this corresponding field is match marking to the number in front of the function sequence. The corresponding touch fields are not in the same line to the function sequences on the touch screen. Operators errors are virtually impossible! The controller recognizes the position of the load alternator at all times; if you select a function that cannot or should not be performed from a certain position, an error message is displayed and the function is not performed. This prevents damage to the mass comparator that could otherwise have been caused by operator error. You can choose the following measurement sequences: x A B B A - cycle 6 x A B B A - cycles 0-99 x A B B A - cycles With the -position load alternator, you can compare: - weights: N - - weights: N - / N - / N - - Combinations: N - / - / N - / - / N - / - The reset key is to stop the measurement also the emergency interrupt key. As soon as you press the reset key, the load alternator is stopped and remains in the position it was in when you pressed reset. Any measurement sequence running at the time is stop. The display indicates that the function was interrupted. You can also press reset to stop a measurement sequence after you have selected the continuous function.

4 Manual operation with the cursor buttons There are four cursor buttons on the front side. With this cursor buttons you can easy operate the load alternator, in it s basic movements. That means turning right and left, lifting or lowering the platform. This is helpful for loading the platform from the front side and other applications. The cursor buttons are only active if the main menu appears on the display. See page no. 5 Movement vertically: Movement horizontally: Four control light identify the current position and the activity of the load alternator. All lights on means that the platform is in the upper position. Movement in all directions is possible. A blinking control light identifies the actually operation relating to the direction of movement. A non active control light means that a movement in this direction is not possible. To start the movement by your choice, press the cursor button. Horizontal movement: - short press turn 90 degrees, - long press ( sec.) turn 80 degrees, Vertical movement: - short press move - from the top toward to centre, or - from the centre to the lower position, or - raise from the lower to the centre, or - raise from the centre to the upper position - long press move - direct from the upper to the lower, - from the lower to the upper position. Note: Two control lights on the printer indicate the capacity of the paper A green light means: enough paper A red light means: paper roll come to end If the paper roll in the printer runs out in the middle of a measuring sequence, the printer switches off. The individual values measured and the results calculated after the printer shuts off are stored in memory. For example: with 6 x A B B A selected, the memory can store data from up to 6 complete measurements. When the memory is full, this is indicated by a crossed-out printer symbol in the display. The load alternator continues according to the selected function sequence. Subsequent measurement data are not stored. To retain the data stored in memory: - Do not interrupt the measurement sequence - Do not press reset - Do not turn off the controller Place a new roll of paper in the printer (see "Maintenance") The stored data are output to the printer.

10 Setting the Delay Time Before Taken Values (XX) : Set number of A B B A - cycles ( 0 ) : Set number of Pre - Cycles ( 00 ) : Delay time before taken values ( 0 ) : More Configurations.. This setting defines a period of time before measured values are transmitted after the mass comparator has been loaded. This time begins as soon as the mass comparator is loaded and the load alternator motor shuts off. Because of, once the mass comparator has been loaded and the stability symbol g is displayed, the weight value may drift slightly until the weight value is recognized as a stable value in order to be transmitted. This time may differ from location to location and must be determined before performing the actual measurement. The factory setting is 0.

11 : Scale - Timeout ( OFF ) : Results via AUX: ( values only ) : Swap keys. (OFF) : More Configurations.. Setting the Scale - Timeout This setting defines the time at which a measurement is to be automatically aborted in the event of an error, for example, if the stability symbol g is not displayed after the mass comparator has been loaded. This may happen if there is any interference due to vibration transferred to the surface on which the mass comparator rests, turbulent air currents or changes in the climatic conditions. Another source of this error is if the wrong substitution weight (F key on the display panel of the mass comparator) was selected for the weight to be measured. An additional source of this error is if the wrong number of weights was selected in the menu Type of comparisons before beginning the measurement; for example using weights when have actually been selected or visa versa. Scale - Timeout ( ON ) = waiting time hour Scale - Timeout ( OFF ) = waiting time infinity To change between ON / OFF press the numeric key.

24 Data Interface ( Aux ) General: The individual measurements printed out during the measurement process are also available as an ASCII string at the data interface (Aux) and can be received by the PC for further processing, The measurements are always output in a couple of a combined data string. Two different formats selectable. (refer configurations page 5 and results via AUX on page ). Results via AUX:. ( values only ) = data output of measurements values only. ( values and time ) = data output of measurements values with numbers of ABBA - cycles and time. Values only The measurements are always output in a couple of a combined data string comprising the measurements A and B or B and A (separated by a space). The number of characters to be transferred is always. The data output is as follows: Measurement A, space, measurement B and CR (carriage return no CR/LF). A line feed signal (LF) must be generated each time after data is received from the PC so that the next measured values to be received appear in a new line. Otherwise, the new values will overwrite the former values. Data output example: CCE000S-L Measurement A: , Measurement B: Data string: CR ± sign for measurement A (one space if sign is + ) - 0 measurement value A with decimal point space ± sign for measurement B (one space if sign is + ) - measurement value B with decimal point carriage return The Data string is characters long and to partition as follows. character = measurement A (B) character = measurement B (A) An example for receiving data on PC from the mass comparator and sorted in an excel file. PC receive: PC Comparator measurement: measurement A measurement B generated:. Measurement A: 0,000, B: 0, ,000 0,00056 LF. Measurement B: 0,000 59, A: 0, ,0006 0,00059 LF. Measurement A: 0,000 5, B: 0, ,0005 0,00057 LF. Measurement B: 0,000 59, A: 0,000 0,000 0,00059 LF 5. A: B:

25 values and times This means that the data string consists of the transaction counter (number of the ABBA cycle), time of value A, value A, time of value B and value B, or these data for B and A, respectively. The calculations of the differences and the final result does not belong to the output. The controller ( control unit ) recognizes different numbers of characters for the measured values so that the data string is correctly sorted with one setting on all automatic mass comparators model. The Data string is characters long and to partition as follows. The partition of the data string is follows: characters = number characters = space 8 characters = time measurement A (B) 0 characters = measurement A (B) characters = space 8 characters = time measurement B (A) 0 characters = measurement B (A) characters = space An example for receiving data on PC from the mass comparator and sorted in an excel file. PC receive: PC Comparator measurement: number measurement measurement time A value A time B value B generated:. Measurement A: 0,00056 B: 0,000 :56:9 0,000 :58: 0,00056 LF. Measurement B: 0,00056 A: 0,0006 5:0:09 0,0006 5:00:6 0,00056 LF. Measurement A: 0,0005 B: 0, :0:0 0,0005 5:05:55 0,00057 LF. Measurement B: 0,00059 A: 0,000 5:09: 0,000 5:07:9 0,00059 LF 5. Measurement A: 0,0008 B: 0, ::6 0,0008 5::9 0,00060 LF 6. Measurement B: A: Connecting cable to PC The two data protocols for the transfer require a semi duplex interface with transmit and receiver lines. As no handshake is required, the relevant handshake lines must be bridged.

26 Programming for external operation with PC Introduction The load alternator can be operated from a PC via the AUX port. Measurement procedures can be freely programmed as required. As the data protocol runs in 7 bit / ASCII format, any terminal program on the PC is suitable for testing the functions. Interface parameters: 9600 Baud EVEN Parity start bit 7 data bits stop bit no handshake, local echo must be switched off Linking the PC to the control unit Switch on the control unit of the load alternator. Make sure that the main menu is displayed on the controller; if necessary key to the Sartorius logo. To link the PC to the control unit, send a CR ( Carriage Return only no CR/LF ) at intervals until the alternator responds with ready for operation??. The control unit display will bring up the message System controlled externally. This message will remain on the display as long as the external control condition persists. The built-in printer is disabled. On the PC monitor, two question marks?? will be displayed indicating the system s readiness to receive commands. If further data (parameters, confirmations) are required, this will be indicated by the appearance of a single question mark?. All command codes consist of a single letter or numeral. (No Carriage Return CR must be sent). The alternator sends back the character it receives (echo) by way of confirmation. Once the command has been executed,?? will be displayed on the screen. External control commands Vertical movements Locating top starting position. Lowering the centering position (middle position). a) Lowering to mass comparator: If load changer centred. Queries with?. - 0 confirms to lowering. b) Locating centering position: If load changer in weighing position. Executes command immediately it is entered. D (Down) Lowering to mass comparator. Executes command immediately it is entered. a) Lowering from the top starting position. b) Lowering from the centering position. Horizontal movements H Rotate 80 clockwise. Rotate 80 counter-clockwise. (CC50000S: Change the horizontal end position). 9 Rotate 90 clockwise. (CC50000S: Change the horizontal end/centre position). N Rotate 90 counter-clockwise.

A R V (All 6 comparisons) Mass comparison all 6 combinations. Only possible when weights are used. When required, entry before measurement starts. (READ) Take weight value from the mass comparator display. Possible only when weighing is in progress and the weight is shown with the stability symbol g. The weight is transferred after a delay, determined by the evaluation time entered. Note! The controller reports error and then stops the system if no correct weight is available. (Version) indicates the comparator model and the software version. Error messages NA (not available) Function not available from current position. SE (scale error) No correct weight available, control blocked. PE (position error) No response from position switch: alternator blocked. The measurements are sent to the PC as a couple of values an ASCII string. The measurements A and B are separated by: a space (hexadecimal 0), and end with: CR (hexadecimal 0D) A line feed signal (LF) must be generated each time after data is received from the PC so that the next measured values to be received appear in a new line. Otherwise, the new values sent will overwrite the former values. 7

30 Maintenance Replacing the Paper Roll Turn on the controller. Lift up the printer cover. Locate the small lever to the right of the paper transport roll and move it towards the front. Insert the start of the paper roll with the inside towards the front into the retainer behind the paper transport roll and move the lever back to its original position. The paper is drawn in automatically. Press the grey push button to transport more paper, if is necessary. Lift back the printer cover. Order no.: 69 C 000 (set of 5 roll thermo paper) Note: If the paper roll in the printer runs out in the middle of a measuring sequence, the printer switches off. The individual values measured and the results calculated after the printer shuts off are stored in memory. With 6 x A B B A selected, for example, the memory can store data from up to 6 complete measurement. When the memory is full, this is indicated by a crossed-out printer symbol in the display. The load alternator continues according to the selected function sequence. Subsequent measurement data are not stored. To retain the data stored in memory: - Do not interrupt the measurement sequence - Do not press reset - Do not turn off the controller Place a new roll of paper in the printer as described above. When you return the lever to its original position, the stored data are printed automatically.
