10 A Weighing mode scrolls across the bottom row and the current weighing mode appears in the top row. Use the and buttons to select Normal or Batch, and then press. If you selected Batch, continue to 5.2B now. Refer to Appendix A for more information on Batching features. If you selected Normal, skip to 5.2C now. In Normal (default) mode the large display will show the gross or net weight, and does not perform any batch calculations. In Batch mode the large display will show the batch or gross weight, and SP 1 and SP 2 function as dedicated batch control setpoints. B C Batching direction scrolls across the bottom row and the current selection appears in the top row. Use the and buttons to select either Negative (for emptying operations), or Positive (for filling operations), and then press. Averaging samples scrolls across the bottom row and the currently selected averaging appears in the top row. Using the and buttons, alter the number of input samples that the controller will average, and then press. The GS125 has input signal averaging, optimising stable measurement. If the change in input exceeds the Averaging window value it will not average, ensuring fast response when there are large differences between readings. Increasing the number of Averaging samples will stabilise measurement, but it will also slow down response rates. A typical value is 4. Input signal in counts Input exceeds averaging window Number of samples Sampling Averaging window in displayed counts D E Averaging window scrolls across the bottom row and the currently selected averaging window value appears in the top row. Using the and buttons, alter the signal averaging window. Then press. If your input signal contains large noise spikes, you can increase the size of the averaging window to ensure that these are still averaged. However, increasing the window size too far will reduce the ability of the controller to respond quickly to real changes in input signal. Setting the Averaging window to its default of 0 will give continuous averaging as per the selected averaging samples. A typical value is 10% of your system capacity. Zero maintenance scrolls across the bottom row and Skip appears in the top row. Use the and buttons to select either Skip or Enter, and press.

11 If you selected Enter, continue to 5.2F now. Refer to Appendix B for more information on Zero Maintenance features. If you selected Skip, skip to 5.2J now. F Auto zero scrolls across the bottom row and the current selection appears in the top row. Use the and buttons to select On or Off, and press. If you selected On, continue to 5.2G now. If you selected Off, skip to 5.2I now. If Auto zero mode is On, the controller s offset will be automatically adjusted so that the instrument reads zero when it senses that the scale is not loaded. G H I J Capture band scrolls across the bottom row and the selected capture band appears. Adjust this value using the and buttons, and then press. This is referenced to the current zero value, and is the maximum number of display counts that the controller will zero within. Capture band can be set from 1 to 254 counts, and should always be set to less than the smallest weight to be measured. Motion band scrolls across the bottom row and the selected motion band appears. Adjust this value using the and buttons, and then press. This provides a rate of change limit setting, to determine the number of counts/second allowed within the Capture band. Motion band can be set from 0 to 255 counts. A typical value is 1 or 2 counts/sec. Zero band scrolls across the bottom row and the selected zero band appears. Adjust this value using the and buttons, and then press. This provides a limit for the number of counts of zero offset allowed to accumulate, relative to the calibrated zero setting. If the accumulated zero offset becomes greater than this window, then the controller displays the current loadcell value and does not zero. The suggested limit for the Zero band is 2% of the calibrated span. Calibration technique scrolls across the bottom row and Skip appears in the top row. Use the and buttons to select: Auto, mv/v, Zero, E_Cal, Cal Set, Remote or Skip, and then press. For Auto, complete steps 5.2K N. For mv/v, complete steps 5.2O Q. For Zero, complete step 5.2R. For E_Cal, complete steps 5.2S T. For Cal Set, complete step 5.2U. For Remote, complete step 5.2V.

12 Calibration technique 5.2J Skip Auto Uses zero and span values to calculate the scale and offset. This is the most accurate calibration method, but requires known low and high input signals, usually supplied by test weights. Zero and span calibration procedures are performed separately. Back to AnlgIP 5.1C Calibrate zero 5.2K No Yes Remove weight L Calibrate span M No Yes mv/v Uses values from the loadcell manufacturer s test certificate. Zero Allows manual adjustment of the calibrated zero offset E_Cal Allows viewing/editing of the electronic calibration values for zero offset and scale factor. Can be used to copy a calibration to another unit, or to 'trim' the existing calibration. Cal Set Select and switch between calibration sets, to save and restore a previous calibration.

30 When the GS125 is in Batch mode (as selected in 5.2A), SP 1 and SP 2 function as designated as batch control setpoints, and a number of their parameters are configured automatically by the controller. Because of this, certain steps will be skipped if your controller is in Batch mode. B SP value scrolls across the bottom row and the current value for the selected setpoint appears in the top row. Using the and buttons, adjust the display value at which the selected setpoint will activate, and then press. If you are editing SP 1 in Normal mode, skip to 6.2D now. If you are editing SP 1 in Batch mode, skip to 6.2G now. Otherwise; continue to 6.2C now.

If you are editing SP 2 in Batch mode, skip to 6.2G now. Otherwise; If you set Trail SP 1 to On, skip to 6.2E now. If you set Trail SP 1 to Off, continue to 6.2D now. A setpoint with Trail SP1 enabled will track the setpoint value of SP 1, with the setpoint value of the tracking setpoint becoming an offset value. D E F SP source scrolls across the bottom row and the activation source for the selected setpoint appears in the top row. Use the and buttons to choose Net/Batch, Live, or Sum, and then press. Where Net/Batch is indicated, the option that will be displayed is controlled by the weighing mode selected in 5.2A. Normal mode = Net, Batch mode = Batch. SP activation scrolls across the bottom row and the current selection appears in the top row. Using the and buttons, select the relay activation to operate Above or Below the setpoint value, and then press. Above: Relay turns on above the setpoint value and off below it. Below: Relay turns on below the setpoint value and off above it. Hysteresis value scrolls across the bottom row and the hysteresis value for the selected setpoint appears in the top row. Use the and buttons to

31 adjust this value if required, and then press. The Hysteresis value defines the separation band between setpoint activation and deactivation. If Above is selected in 6.2E, then the Hysteresis value determines how far the input must fall below the SP value to deactivate the setpoint. If Below is selected in 6.2E, then the Hysteresis value determines how far the input must rise above the SP value to deactivate the setpoint. Hysteresis band Energised Above Hysteresis band Energised Below G H I Make delay scrolls across the bottom row and the current make delay time for the selected setpoint appears in the top row. This is the time delay between setpoint activation, and when the relay turns on. Adjust this value in 0.1 second increments using the and buttons, and then press. User access? scrolls across the bottom row and the direct access permission setting for the selected setpoint appears in the top row. Use the and to select either Off or On, and then press. When enabled, this option allows the selected setpoint's value to be edited directly after pressing the button, without needing to enter a PIN number or go through all of the other options. Each setpoint can individually have this option enabled or disabled. See Section 7. Edit setpoint scrolls across the bottom row and Skip appears in the top row. You are now back at 6.2A. To edit another setpoint, follow the instructions from 6.2A I again. If you do not wish to edit another setpoint, press now to skip to 6.3. 6.3 - Edit F2 PIN number A B Edit F1 PIN scrolls across bottom row and Skip appears in the top row. Use the and buttons to select Skip or Enter, and then press. If you selected Enter, continue to 6.3B now. If you selected Skip, the display will return to normal operating mode. Enter new F2 PIN scrolls across bottom row, and the current F2 PIN number (default 2010) appears in the top row. Use the and buttons to adjust your F2 menu entry PIN number as desired, and then press. The display will now return to normal operating mode.

32 7 SETPOINT EASY ACCESS If none of the setpoints have their easy access option enabled (see 6.2H) then this feature will be disabled and the button will not respond to a short button press. A Begin by pressing the button for less than 3 seconds. B C The name of the first access-enabled setpoint will appear in the bottom row and the current value for that setpoint will appear in the top row. Using the and buttons, adjust the selected value. Then press to accept and continue. The name of the next access-enabled setpoint will appear on the display, along with its setpoint value. Repeat step 7B. The easy access menu will proceed through all access-enabled setpoints in this fashion. Pressing for the last enabled setpoint will exit and return to the operational display. 8 RESET PIN NUMBERS If you have forgotten your PIN number(s), follow the procedure below to reset both the F1 and F2 PINs to their factory default of 2010. A Press, and at the same time. (This key combination can be difficult to execute and you may need several tries to get it right.) B When successful, a factory identification text will scroll across the display, followed by PIN RESET TO DEFAULT C Reset the default PIN numbers if required by following the instructions in 5.7 (for the F1 menu) and 6.3 (for the F2 menu), entering 2010 whenever you are prompted for your current PIN.

33 A APPENDIX A - BATCHING To access batching features, the controller's Weighing Mode must be set to Batch (see 5.2A). It is then possible to Batch or Reset Batch from the button or input pins (see 5.4 to configure). Batch - This function is used to display the live weight of the system but take regular 'batches' of product without continually changing the setpoint. When the Batch function is activated the display will tare and SP 1 and SP 2 will turn on. Batch Reset - This resets the batch value to zero and halts any batching operations. Batching Direction - This parameter is set in 5.2B, and is based on whether product is being added to or discharged from the weighing system. Positive Direction is when the weight increases as product is added to the weighing system. Set Batching Direction to Positive. Eg. Setting a setpoint value of 50Kg for SP 1 and 5Kg for SP 2 and enabling batching mode (Pos direction) will allow the user to fill a container to 50Kg with a potential speed change at 45Kg (50Kg 5Kg). The cycle is initiated when the Batch function is triggered. The display will tare, and when 45Kg net weight is shown, SP 2 will drop out. If product continues to feed, at 50Kg SP1 will drop out, halting the fill. If Flash Gross is enabled (see 5.3F) the gross weight will be displayed (Eg. Now 1050Kg, if the starting gross weight was 1000Kg). The user can then trigger the batch function again to call another 50kg batch. Negative Direction is when the weight decreases as product is removed from the weighing system. Set Batching Direction to Negative. Eg. Setting a setpoint value of 50Kg for SP 1 and 5Kg for SP 2 and enabling batching mode (Neg direction) will allow the user to fill a container to 50Kg with a potential speed change at 45Kg (50Kg 5Kg). The cycle is initiated when the Batch function is triggered. The display will tare, and when 45Kg net weight is discharged, SP 2 will drop out. If product continues to be discharged, at 50Kg SP1 will drop out, halting the product flow. If Flash Gross is enabled (see 5.3F) the gross weight will be displayed (Eg. Now 950Kg, if the starting gross weight was 1000Kg). The user can then trigger the batch function again to call another 50kg batch. In this mode if there is not enough product to drop a batch then the instrument will advise the operator by showing the message Low Product. If gross > SP 1, the Batch Value is reset to zero and the display flashes Batch. SP 1 is turned on (and SP 2 if set up). If gross < SP 1, batching is not started.

34 B APPENDIX B - ZERO MAINTENANCE The Zero Maintenance feature is used to automatically compensate for slow drift in loadcell output due to factors such as temperature change, rain and dust accumulation over time. When Auto Zero is enabled (see 5.2F), the controller display will zero automatically if changes to the loadcell are within the user specified Capture Band, Motion Band and Zero Band parameters (see 5.2G-I). Capture Band (5.2G) - This is the maximum number of display counts that the controller will automatically zero within. The Capture Band is referenced to the current zero value. If the input value on the loadcell is not within the Capture Band setting then the controller displays the current loadcell value and does not zero. Capture Band can be set from 1 to 254 counts, and should always be set to less than the smallest weight to be measured. Setting the Capture Band to 0 will turn the auto zero feature off. Motion Band (5.2H) - This provides a rate of change limit setting, to determine the number of counts/second allowed within the Capture Band. If the count change is within the Capture Band, but the speed of the count change is more than the selected Motion Band, then the controller displays the current loadcell value and does not zero. The Motion Band can be set from 0 to 255 counts. Typical value is 1 or 2 counts/sec. Zero Band (5.2I) - This provides a limit for the number of counts of zero offset allowed to accumulate, relative to the calibrated zero setting. If the accumulated zero offset becomes greater than this window, then the controller displays the current loadcell value and does not zero. The suggested limit for the Zero Band is 2% of the calibrated span. If the controller fails to zero, check for mechanical or electrical faults.

35 C APPENDIX C - INPUT FUNCTIONS A number of user programmable functions are accessible from the button and input pins (see 5.4). Note that availability of the Tare/Batch feature is subject to your selection in 5.2A. User programmable input functions Function Btn/Pin & Activation Description Time Hold Continuous Freezes the display value. Lock Continuous Locks the control panel. Tare ½ sec Tares display value (flashes Tare). Batch (see App. A) 2+ sec Resets tare to zero (flashes Tr Rst and then shows gross). ½ sec Performs a batch operation If a batch is already in progress, no function will be performed. If you have just powered up following a power loss during batching, the controller will resume without resetting the batch value. 2+ sec Resets the batch value to zero and flashes Bt Rst. Any current batching operations will be halted. Zero ½ sec Zeroes the weight if the zero offset (i.e. the difference between the current no load weight and the calibration no load value) is within the Zero Band (see Appendix B). If the offset is less than the limit set in Zero Band (see 5.2J), the zero value is updated and the display flashes Zero. If the offset is greater than the limit set in Zero Band, the zero value is not updated and the display scrolls Outside Of Zero Band! 2+ sec Resets the zero offset value to the original calibration offset value. Display flashes Rs Zer and then shows gross. Peak ½ sec Displays the peak value for 2 seconds. 2+ sec Sets the peak value to the current input value (flashes Pk Rst). Continuous Displays the peak value continuously.

36 User programmable input functions Function Btn/Pin & Activation Description Time Peak Rst Continuous Sets the peak value to the current input value (flashes Pk Rst). Print ½ sec When the GS125 is in Ranger A serial mode (see 5.6A), triggering the Print function will send a Ranger A output string. The Output Mode (5.6D) should be set to Pulsed in order to send a single Ranger A output string. When the GS125 is in Print serial mode (see 5.6A), triggering the Print function will print a Weigh Ticket (see Appendix D.5 for more information). StartLED Continuous The green Start light on the traffic light annunciator will turn on when this input is active. Only available for models with a traffic light annunciator character installed. StopLED Continuous The red Stop light on the traffic light annunciator will turn on when this input is active. Only available for models with a traffic light annunciator character installed.

37 D APPENDIX D - SERIAL MODES D.1 - Custom ASCII mode Custom ASCII is a simple, custom protocol that allows connection to various PC configuration tools. ('Custom ASCII' differs from the 'Modbus (ASCII)' protocol used by some devices.) Custom ASCII command strings must be constructed in this order: <Start> <Controller Address> <Read/Write Command> <Register Address> <Separator Character> <Data Value> <Message Terminator> Start - Use 'S' for the start character of a command string (not case sensitive). This must be the first character in the string. Controller Address - Use an ASCII number from '1' to '255' for the controller address. If the character following the start character is not an ASCII number, then address '0' is assumed. All controllers respond to address '0'. Read/Write Command - Use ASCII 'R' for read, 'U' for unformatted read, or 'W' for write (not case sensitive). Any other character aborts the operation. In Custom ASCII mode, data is normally read as formatted data (which includes decimals and any text characters that may be selected to show units). However it is also possible to read unformatted data by using a 'U' in the read command. There is no unformatted write command, as when writing to fixed point registers, any decimal point and text characters are ignored. Register Address - The register address for the read/write operation will be an ASCII number from '1' to '65535'. This character must be specified for a write command, but may be omitted for a read command, (in which case the controller will respond with the data value currently on the display). Separator Character - The separator character can be either a space or a comma, and is used to separate the register address from the data value. Data Value - Must be an ASCII number. The absolute limits for this number are 1000000 to + 1000000, but note that not all registers will accept this range. Message Terminator - This is the last character, and must be either a '$' (dollar) or an '*' (asterisk). Neither of these characters should be used elsewhere in the

38 message string. If '$' is used, a 50ms minimum delay is inserted before a reply is sent. If '*' is used, a 2ms minimum delay is inserted before a reply is sent. Custom ASCII Read/Write Examples Example Description SR$ Read display value from all controllers, 50ms delay. S15R$ Read display value from controller address 15, 50ms delay. S3U40* Read unformatted data in channel 4 from controller address 3, 2ms delay. S2W2 10000$ Write 10000 to the display register of controller address 2, 50ms delay. SWT CHAN_1$ Write ASCII text string Chan_1 to channel 1 text register, 50ms delay. Controller Response - After the controller has completed a read or write instruction, it responds by sending a carriage return/line feed (CR/LF) back to the host. If the instruction was a read command, the CR/LF follows the last character in the ASCII string. If it was a write command, CR/LF is the only response sent back. The host must wait for this before sending further commands to the controller. If the controller encounters an error, it will respond with a null (0x00) CR/LF. Custom ASCII Registers - Active for models with relay output installed 16 Bit Unsigned Address Function 239 Alarm status (SP1=Bit 0, SP2=Bit 1, SP3=Bit 2) 181 183 Hysteresis (SP1=181, SP2=182, SP3 =183) 197 199 Make delay (SP1=197, SP2=198, SP 3=199) 32 Bit Signed Address Function 257 Tared/Batch weight (net) 9 mv 305 Live weight (gross) 69 Tare value 57 Peak 59 Valley 111 Setpoint 1 113 Setpoint 2 115 Setpoint 3 381 D/A scale low value 405 D/A scale high value

39 D.2 - Modbus (RTU) mode Modbus (RTU) is an industry standard RTU slave mode that allows connection to a wide range of devices. Modbus registers are all holding registers, and should be accessed via function codes 3, 6 and 16. Register addresses are displayed in the Modicon 6-digit addressing format. I.e. Register 65=400065 (subtract 1 for direct addressing). Modbus (RTU) Registers - Active for models with relay output installed 16 Bit Unsigned Address Function 400239 Alarm status (SP1=Bit 0, SP2=Bit 1, SP3=Bit 2) 404181 404183 404197 404199 Hysteresis (SP1=404181, SP2= 404182, SP3=404183) Make delay (SP1=404197, SP2= 404198, SP3=404199) 32 Bit Signed (2 x 16 Bit) LSW MSW Function 400257 400258 Tared/Batch weight (net) 400009 400010 mv 400305 400306 Live weight (gross) 400069 400070 Tare value 400057 400058 Peak 400059 400060 Valley 400111 400112 Setpoint 1 400113 400114 Setpoint 2 400115 400116 Setpoint 3 400381 400382 D/A scale low value 400405 400406 D/A scale high value D.3 - Gedge mode This serial mode is used to drive Gedge displays. Depending on your output format selected in 5.7C, the Gedge output string will be constructed as shown: C1= <STX> <Displayed Weight> <ETX> C2= <STX> <Displayed Weight> <D2> <D3> <D4> <D5> <D6> <D7> <ETX> C3= <STX> <Gross Weight> <Tare Weight> < Net Weight> <D2> <D3> <D4> <D5> <D6> <D7> <ETX>

40 Gedge Command Strings STX Start of transmission ( $02 ) ETX End of transmission ( $03 ) CR/LF Carriage return and Line feed ( $0D $0A ) Weight 8 ASCII alpha/numerics: <Space or minus sign> <Space> <6 digits> (E.g. " 002387") or <Space or minus sign> <6 digits and decimal> (E.g. " 002.387") D2 Displayed weight identity. G: Gross. N: Net. T: Tare. D3 M: Scale is in motion. S: Scale is still. D4 I: In scale. O: Over scale. U: Under scale. D5 Z: Gross is zero. ASCII Space: Gross is not zero. D6 E: Stored tare is not zero. ASCII Space: Stored tare is zero. D7 P: Print key operation. ASCII Space: No print key operation. D.4 - Ranger A mode Ranger A is a continuous output, used to drive remote displays and other instruments in the Rinstrum range. (Ranger is a trade name belonging to Rinstrum Pty Ltd.) Ranger A output strings are constructed as shown: <Start> <Sign> <Output Value> <Status> <End> Start - STX character (ASCII 02) Sign - Output value sign (space for + and dash for -) Output Value - Seven character ASCII string containing the current output value and decimal point. (If there is no decimal point, then the first character is a space. Leading zero blanking applies.) Status - Single character output value status. 'U'=Under, 'O'=Over, 'E'=Error. End - ETX character (ASCII 03)

41 D.5 - Print mode This mode outputs a Weigh Ticket (as shown) to the serial port when the Print function is triggered from the button or rear input pins (see 5.4). The weigh ticket shows the peak value of the selected Serial Data Source (as set in 5.6C), and the Units (selected in 5.6E). Note that changing the display units in 5.6E does not perform any conversion calculations. You will need to scale the instrument to match the printed units. A date and time will also be printed on the Weigh Ticket. Please see 5.7A F to set the date and time. D.6 - Summing mode When Summing is enabled, the value shown on the display will be the sum of the strain gauge input, and the input value from the serial port. Care should be taken in Summing mode to ensure that both weighing instruments are outputting the same measurement scale. Last Resort in Summing mode The last resort option can be used when trying to connect the GS125 with an instrument which is not included in the device type list, or one which is using a custom output string. It allows the user to define key characters in the output string, which enables the GS125 to accurately extract the weight value from the string. Start of string character / 2nd character / 3rd character Many output strings contain a fixed start character at the beginning of the string. You may choose to either specify this start character, or select Ignore
