1.0 Principle The Weigh Feeder consists of a conveyor belt whose material load is continuously weighed with a measuring device. The mass flow is calculated from the product of Belt Load (Loadcell value) and belt speed (Tacho frequency). The amount of material being conveyed is controlled by controlling the belt speed. This is done by generating the setpoint and control signals to control a suitable drive controller. Belt speed is monitored to ensure that the required speed is being achieved by the drive controller. In addition to controlling the material flowrate, the system can also control a Pre-feeder to control the material bed-height 1.1 TUC-6 Weigh Feeder System, Overview: The unit is operated using the TUC-6 keypad and the 2 line * 16 digit VFD display. The display values are called using fixed keys or displayed through pull-down selection. The Configuration of the system is determined by the parameter values. To do this, a selection is made from the fixed values in the configuration menus or a parameter is entered using the front keypad. 1.2 System Features - Fail safe EEPROM memory for configuration parameters - Battery buffered RAM for working data - Date/Time in battery buffered Real Time Clock - Integrated keyboard and display - Data memory even with replacement of interface cards - Upto 24 inputs / 20 outputs - 2 Impulse outputs - Analog to Digital and Digital to Analog signal interfaces - Curve correction - Zero correction - Inbuilt PLC for easy adaptation to different control schemes - Alphanumeric Text displays for Fault diagnosis



2.0 Functions 2.1 Modes of operation The system can operate in any one of the following 5 modes, i) Interlock - Gravimetric Mode In this mode, the system operates through External setpoint in the form of analog 4-20 mA signal or setpoint through the serial interface. Start/Stop to the system is either through external digital Inputs or through the serial Interface. ii) Interlock - Volumetric Mode In this mode, the system operation is un-regulated (Volumetric). Setpoint in this mode is from an external 4-20 mA signal and Start/Stop to the system is through external digital Inputs. iii) De-Interlock - Gravimetric mode. In this mode, the system operates through setpoint entered through the TUC keypad. System Start/Stop is through the keys provided on the keypad. iv) De-Interlock - Volumetric mode. In this mode, the system operation is un-regulated (Volumetric). Setpoint and Start/Stop is from the TUC keypad. v) Local Mode. In this mode, Setpoint & Start/Stop commands to the system are from the Local Control station. In this mode, system operation is un-regulated (Volumetric) i.e. the setpoint from the Local control station directly varies the belt speed. 2.2 Belt off-track monitoring



Off-track running of the belt can be monitored via an external signal from the Belt tracking sensors to the control unit. 2.3 Zero setting Belt related influences on the belt load can be compensated by means of zero correction. To do this, the correction process is started with the belt running idle. The zero correction value, with which the belt load is set off, is calculated automatically after the zero correction process. The zero correction is initiated from the front keypad. 2.4 Linearisation of belt load If the load on the measuring cell is not linear in the whole range, the load can be laniaries by entering upto ten correction points. 2.5 Programmable Scale Control To achieve optimum adjustment of the dosing control as per the customer's requirements, a PLC is built into the Controller. This enables digital signals within the control unit and to the process to be freely defined. Standard PLC programs are implemented internally for standard configurations. These may be called directly and used or modified to suit diverse application needs. 2.6 Error Messages Faults/Errors caused by incorrect operations are displayed in clear text in the control display. Faults are also made available at the output in the form of potential free contacts. 2.7 Scale types 2.7.1 Directly extracting weigh feeder Material is extracted directly from a hopper, without a pre-feeding device. 2.7.2 Weigh Feeder with pre-feed regulation As a result of variation of belt speed, required for output regulation, a varying bed-height of material may occur on the conveyor belt. If a constant bed-height of material is



required or in the event of unfavorable material properties which do not permit direct extraction, pre-feed regulation is necessary. For this purpose, an output setpoint can be generated to control a pre-feed device. This output value is coupled to the flow regulator i.e changes in flow setpoint automatically adjusts the pre-feed device. 2.7.3 Flow metering device With flow metering devices no speed tachometer is available. Regulation of mass flow is realized by regulation of material load. In this mode, system operation is with fixed internal tachometer. 2.7.4 Batch operation By specifying a target quantity, it is possible to proportion individual batches. In this mode, proportioning is done as per the prescribed setpoint. After the target quantity of material has been conveyed, an alarm or automatic belt stop command can be generated. 2.7.5 Measuring Mode It is possible to bypass feed regulation and operate the unit only in measuring mode, for equipments like Belt Weighers. 3.0 Interfaces 3.1 Computer Interface It is possible to enable remote monitoring and control of the system, by connecting the unit to a master controller through the serial interface. Modbus RTU and Profibus protocol options are supported through use of optional modules. 3.2 Pulse Output Two pulse outputs are available from the system corresponding to the quantity being conveyed. The resolution & pulse width of the Totaliser pulses are configurable. 3.3 Analog outputs



Analog outputs are available for display and/or measurement tasks. Upto 4 analog current outputs can be generated from the system. Each individual output can be selected to various measurement/control variables, such as Feeder setpoint, Pre-feeder setpoint, Material Feedrate, Belt loading, Belt Speed. 3.4 Digital I/O A maximum of 24 inputs and 20 outputs are available for controlling the weigh feeder and other plant interlocks. Outputs are available corresponding to various status and fault conditions in the system.

2.5 Batch Operation The Feeder can be selected for Batch mode operation. In this mode, a fixed quantity of material can be delivered by the Feeder and an alarm generated or the system stopped, if required. The quantity setpoint values are entered in SET2 menu. Two Setpoint parameters, 'Q1' & 'Q2', are provided in the system. Selection between 'Q1' and 'Q2' is through marker 'M024'. Each Quantity setpoint (Qx) is associated with a corresponding Dribble value (qx). When operating in the Batch mode, an alarm is generated after delivering 'Q-q' quantity of material. 'q' is usually the amount of material overfed by the feeder after it is stopped. Conditions: - Weigh feeder configured for Batch mode operation Operation : When the feeder is started in Batch mode, Totaliser, S1 is cleared if greater than 'Q'. Totaliser, S1 increments upto 'Q-q' and "Quantity Over!" is displayed. Marker 'M059' is set. This marker can be used in SPSS to stop the feeder if requried. Pressing 'CL' key clears the alarm display and resets 'M059' marker if set. 2.6 Error Acknowledgment 'CL' key is used to acknowledge errors. Display The Error text message is displayed in line 2. All Error texts are characterised with "!" in the last column Note: If an error is already in the display, further errors will not be displayed until this error has been acknowledged.

1.0 Programmable Logic Controller 1.1 Description TUC-6 has an inbuilt PLC, that is used to control the Digital Inputs, Digital Outputs and Internal Memory Flags (Markers). The Programmable control system processes the instructions from the control program, SPSS. The Input data and Output data for the control program are physically in the TUC RAM, logically in the so called "process images". The instructions in the control program with the variables "A E M T" always refer to the process image in RAM. The programmable control system continuously operates on the control program in the following sequence, -Transfer hardware inputs to the TUC RAM -Execute instructions in the control program (SPSS) -Transfer output process image to the Hardware Outputs Several variable types are used in the PLC program. "A" stands for outputs, "E" for inputs, "M" for marker and "T" for timers. Addition of "N" (UN or ON) means that the associated variable is scanned for signal status "0" ; otherwise the scanning of variables is for signal status "1". 1.2 PLC Operation The programmable control system consists of a 1_bit_wide BIT accumulator. Instructions in the PLC can be classified into two types; one type operating on the result of previous instruction (Result Instruction) and second changing the accumulator value (Command instruction).



The control program is always started with accumulator = "1". ' Command ' instructions change the accumulator value till a ' Result ' instruction is encountered. After execution of all ' Result ' instructions, accumulator is again made ' 1 ' and the sequence is continued Example: 000 *SPSS01 ;Comment Line 001 UM 045 ;Command Instruction - Accumulator = '1' 002 UM 068 ;Command Instruction - 'AND' result of above instruction with M068 value 003 UNE 050 ;Command Instruction - 'AND' result of above instr. with 'NOT'of E050 input. 004 =A 008 ;Result Instruction 005 UE 000 ;Command Instruction - Accumulator = '1' : : 1.3 Instructions Instruction Meaning Command Result UE xxx AND operation with INPUT Y N UA xxx AND operation with OUTPUT Y N UM xxx AND operation with MARKER Y N UT xxx AND operation with TIMER Y N UNExxx AND + NOT operation with Input Y N UNAxxx AND + NOT operation with Output Y N UNMxxx AND + NOT operation with Marker Y N UNTxxx AND + NOT operation with Timer Y N OE xxx OR operation with INPUT Y N OA xxx OR operation with OUTPUT Y N OM xxx OR operation with MARKER Y N OT xxx OR operation with TIMER Y N ONExxx OR + NOT operation with Input Y N ONAxxx OR + NOT operation with Output Y N

The differentiation between inputs and outputs is done by the "signal direction" on which these variables are based. Inputs are signals from "outside" to the control program, and outputs are signals from the control program to the external system. Thus inputs can only be read, while outputs can be allocated. Inputs and Outputs are available outside the TUC-6 system with the help of digital I/O card. Markers are internal variables and serve as memory within the control system. They are available outside the control system when they have been copied onto outputs. Markers are classified into Input Markers and Output Markers. Input markers are used to control the software execution while Output markers are derived as a result of the software execution. 1.5 Timers Ten ON-delay timers are available in the system for timing functions.



Instruction "LT xxx" loads timer "xxx" if the result of previous instruction is "1". Instruction "SIT yyy" starts the previously loaded timer with time "yyy". Timers continue to run till the input condition is "1" or till the set time is over, which ever is earlier. After completion of set time, the respective Timer "Txxx" bit status is made "1". Timers are reset (Txxx is made "0") with "RT xxx" instruction. Instruction "RT xxx", if executed while timer is running, stops the timer. 2.0 Programming Functions 2.1 General The Programmable Logic Controller in TUC-6 serve to adjust the scale to the plant control logic.
