Preface

Instruction for use of manual

This manual is for reference by the operators and installers of XK3190-C602 indicator during their operation or installation and testing. Chapter 1 and chapter 2 of this manual introduce the technological features and parameters of the indicator in a general manner. Chapter 3 and chapter

4 describe the installation, parameter setting and calibration methods which can be referred to by installers and repairmen as well as by on-site operators who need to adjust the working modes and parameters of the indicator. Chapter 5 gives out the details of on-site operation methods when the indicator is used to control quantitative scale. Chapter 6 explains the ways and working procedures of the indicator when it is used to control quantitative scale, which can assist installers and operators in understanding the setting of each parameter. Chapter 7 covers the on-site operation methods of indicator when it is used to control catchweigher. Chapter 8 focuses on the ways and working procedures of the indicator when it is used to control catchweigher, which can help installers and operators understand the setting of each parameter. The annexes provide information for error prompt message, communication format, and general problems.

During use of this manual, you may browse it first, and then select the contents related to your current task while omitting the part not concerned. After you have got a general understanding of the indicator, you can read it once again carefully.

The following glossaries are used in the manual:

Parameters are short for configuration parameters. The configuration parameters of quantitative scale include the data setting of timing constant, batching value, and lead, while that of catchweigher includes the data setting of timing constant and catch weight limit. Configuration parameter 2 stands for the second set of parameters. Please note that only

嫐SET 2嬪parameter can be separately configured as 5 sets, while

嫐SET 1嬪can only have 1 set.

Lead During the feeding of quantitative scale, the weight of material on the load carrier is less than the weight of material delivered by the feeder since part of the delivered material is still in the

X K 3 1 9 0 C 602 air and has not reached to the load carrier. To obtain the predetermined material weight, it is necessary to turn off the feeder in advance. The weight involved in the leading is called a lead. For

C602, “self-correction of lead” function can be activated to ensure the accuracy of final weight.

Gradual feed When the feeding to quantitative scale is finished, the material weight is less than the predetermined weight and the difference is beyond the tolerance, the indicator can start slow feeding repeatedly and shortly to make the loaded weight approach to the predetermined value.

Add signal is short for “adding input signal is allowed”. Only when the add signal is valid can the

C602 output feeding control signal.

Discharge signal is short for “discharge input signal is allowed”. Only when discharge signal is valid can C602 output discharge control signal.

Zero zone is the weight limit in additive scale which is used to judge whether the material in hopper is completely discharged.

1. During discharging, it is deemed completed when the indicator shows the gross weight is below zero zone.

2. The indicator can print and totalize only when the material weight is above zero zone.

For catchweigher, the self-control catchweigher can start weighing process only when the weight signal is above zero zone and can print and sum when the calculation result of material weight is above zero zone.

Additive scale is the quantitative scale used for batching control of added material weight in load carrier (like hopper etc), for example, the hopper-type quantitative packing scale.

Subtracting scale is the quantitative scale used for batching control of subtracted material in the load carrier (like hopper). It is also called weight loss scale.

Negative scale is the indicator to measure the weight removed from the load carrier. Subtracting scale works as negative scale during feeding.

Channel is the range of object weight. C602 indicator can be divided into 5 weight ranges, also called 5 channels. Each channel has 1 corresponding switch output signal.

Out-of-tolerance treatment When it is valid and the materials fed by quantitative scale is less than the lower limit of batching value (subtracting tolerance of batching value), while there is no gradual feed function, or when the fed material is more than the upper limit of set value (additive tolerance of batching value), the quantitative scale will stop running, waiting for manual treatment.

When the weight meets the tolerance requirement, the quantitative scale will resume the interrupted work.

Peak holding When the catchweigher captures an object weight, it will be displayed until the weight of next object is captured. The main display or auxiliary display can be selected to show

X K 3 1 9 0 C 602 the captured object weight.

Initial zero-setting is the first zero-setting operation after startup. It can be set as automatic zero-setting upon startup (initial) or manual zero-setting. If zero-setting upon startup is prohibited, the indicator maintains the zero point at shutdown. The initial zero-setting range can be selected and generally ±10%Max is set. If the variation of zero point of scale exceeds the initial zero-setting range, initial zero-setting cannot be carried out. The zero-setting range

(generally ±2%Max) is based on the zero point determined during initial zero-setting.

Main display The 6-digit 0.56 LED digital tube in upper part of display window and the indicators on both sides are main display of C602 indicator, which is used to display major contents such as weight and set value etc..

Auxiliary display The 6-digit 0.4 LED digital tube in lower part of display window is auxiliary display of C602 indicator, which is used to display accumulative value, summation, date, time, operation procedure etc.. Parameters are prompted during parameter setting and error signal is displayed in case of error prompt.

Attention: the indicator shall have sound and reliable earthing protection so as to ensure the operation stability and safety of operator.

Installation method of indicator

Unscrew two M4 fastening screws on both sides at back of the indicator, remove the binding, insert the indicator into the installation hole, insert the binding again and fasten it with M4 screws.

Disassembly and assembly of indicator

When changing analogue output mode or RS422/RS485 upper and lower resistance or the terminating resistance, the indicator should be opened to adjust the position of corresponding jumper at the main board or power panel. Please carry out the disassembly and assembly of the indicator according to following method to avoid any damage.

Attention: many elements in the indicator are sensitive to static electricity. Please get rid of charge in human body before disassembling the indicator by touching wall or other earthed object so as to protect the indicator against damage by static electricity.

Disassembly method: remove all screws in back panel of indicator, remove the back panel, carefully draw out the upper power panel and the lower main board to adjust corresponding jumper.

Assembly method: carefully insert the main board and power panel into the slots in the housing. When it is about to be fully inserted, and encounters significant resistance, as if blocked by something, at this time, do not insert it forcedly, instead, shake the circuit board and carefully insert it. If fails, check whether the contact pin of connector is deformed and whether there is any abnormity in double socket in the display panel. When circuit board is inserted to its place, mount the back panel and fasten all screws. Please note that the screws in the four corners are self-tapping screws and the rest are M3 * 6 SL screws.

III. Connection between load cell and indicator

1. 7-pin electrical male plug are adopted for connection of load cell. Figure 3-5 shows the meanings of each pin.

2. When junction box is used to connect several load cells or extend the cable of load cell, six-wire connecting method must be adopted. When 1 load cell is used and the cable is not extended, four-wire system can be adopted. Under this condition, it is necessary to short connect the EX+ and SEN+ with EX- and SEN- respectively.

3. The load cell and indicator should be reliably connected and the shielded line of load cell should be reliably connected with GND terminal. The connecting line can not be plugged in and out when the indicator is powered on in order to prevent any damage to the indicator or load cell by static electricity

4. The load cell and indicator are both static sensitive equipments, so anti-static measures must be taken during the use. It is strictly forbidden to carry out welding operation or other operations with high current on the weighing platform. In the stormy season, lightening prevention measures must be taken reliably to prevent any damage to load cell and indicator caused by lightening stroke, and to guarantee the personal security of operators and safe running of weighing devices and relative equipments.

IV. Printer interface

1. Parallel printer interface adopts the standard 25-pin D type jack socket. Figure 3-6 shows the meaning of each pin. The indicator can be connected to printer by standard parallel interface printer cable. The 13th pin is +5V output which can be used to connect micro printer with peak current below 2A.

(Fig. 3-7) for the meaning of each pin. Busy means the printer is busy.

Setting of printer

Correctly set the parameters 7, 8, and 9 (see table 4-3 in chapter four) of SET 1 according to the printer model and printing language (Chinese or English). If the printer not listed in the table is to be used, try to select the model with similar printing command format with those listed in the table.

Selection of micro printer

It is suggested to adopt the mirco printer with Chinese library, available for printing at least 16

English charanters in 1 line. When micro printer without Chinese character database is used, only

English printing mode is available for selection.

The micro printer shall support the following commands:

Switch to Chinese printing: ESC 8 n (0x1b, 0x38, n)

Reverse printing: ESC C n (0x1b, 0x63, n)

Our company can select the micro printer for customers, which has been verified in the C602.

V. Scoreboard display interface

The scoreboard display interface is the 20mA current loop interface which is capable of driving various scoreboards.

Please refer to appendix C for the data format and oscillograph of scoreboard display interface.

In the figure, DP+ and DP- are the 20mA current loop interface of scoreboard.

Figure 3 7 Serial Communication and Scoreboard Display Interface

VI. Serial communication interface (1)

Serial communication interface (1) is RS232C interface which is capable of transmitting AD switch code or weight data to the PC at high speed, the data rate is equal to AD switching speed.

The function of serial interface (1) can be set by SET 1 parameter 6A and its baud rate can be set by SET 1 parameter 5A. Refer to appendix D for data format.

Serial interface (1) can also be used as the drive interface to connect the serial interface printer. The XOFF/XON flow control protocol can be adopted and Busy signal can be used to control the transmission of printing data.

VII. Serial communication interface (2)

Serial communication interface (2) can transmit data to PC as well as receive control command issued by the PC and set parameter. Serial communication (2) can communicate with

PC by selecting continuous send or command response. The function of serial interface (2) can be set by SET 1 parameter 6B and its baud rate can be set by parameter 5B.

The factory setting of serial communication interface (2) is RS232C, and it can be automatically set as RS422/485 interface. The jumper JP4 chooses different positions based on the selection of RS232 or RS422/484. See figure 3-5 for the connection of communication interface,

X K 3 1 9 0 C 602 in which the right RxD and TxD are RS-232 (2) interface while the TXD0, TXD1, XD0, and

RXD1 are RS422/485 interface. Only one of the two can be selected in operation. If terminating resistance and pull-up resistance or pull-down resistance needs to be connected, open the housing, draw out main panel, and short jumper JP3 in main panel. When 1-2 are shorted, the pull-down resistance is valid, when the 3-4 are shorted, terminating resistance is valid, and when 5-6 are shorted, the pull-up resistance is valid. If RS485 communication mode is used, please short TXD0 and RXD0, TXD1 and RXD1 terminals respectively. Parameter SET 1 6B must select 2. At this time, the communication interface is working in command response mode to prevent the conflict of bus. The range of common-mode voltage of RS422/RS485 mode is 3±7V.

1. Continuous send mode

When SET 1 parameter 6B is set as 1, continuous send mode is active. See table 3-1 for data format. All data are ASCII code, each byte is made up of ten bits, with the first bit as the start bit and the tenth bit as the stop bit, the bits in between are data bits, no check bit is available.

The transmitted data are the current weight value (gross weight or net weight) measured by the indicator, each frame has 9 bytes. See table 3-1 for format.

For instance, if the indicator measures a gross weight of 50.00 (kg), it will send data as follows:

“G 50.00”;

If the indicator measures a net weight of 0.040 (kg), it will send data as follows:

“N 0.040”.

2. Command response mode

When SET 1 parameter 6B is set as 0 or 2, the serial interface 2 works in command response mode. If serial interface 2 works in continuous send mode, when the PC sends correct command to the indicator in command response mode, the indicator will automatically switch to command response mode. If the PC does not send read in EEPROM command, C602 will still work in continuous send mode after next startup. With regard to response mode, the PC sends

“setting the communication mode into continuous send mode”, the indicator will switch to continuous send mode.

Please refer to appendix E for the communication format of command response mode.

VIII. Control interface and indicating lamp

See figure 3-8 for optical isolation switching value interface. O0 ~ O7 are the switch output signal terminals for the 8 open collectors, with each terminal absorbs current 100mA at maximum and the total current shall not exceed 200mA. I0 ~ I7 are the 8 Switch input signal terminals. 0V and +12V are the connecting terminals for 12V external isolation power supply, with maximum capacity of power supply of 200mA. The output terminal can be directly connected with the cable terminal of relay box which is supplied with the C602 indicator to transform the output mode of C602 into relay output. The signal input terminal of indicator can connect with +12 ~ +24V voltage as compared with 0V terminal, it can also be shorted with

+12V to be effective signal. Attention: the 0V terminal on back panel is isolated from the indicator housing and weighing load cell interface GND terminal. The input and output status indicating lamps on the indicator panel display the actual status of input and output terminals.

Attention: among the input and output terminals, it is prohibited to short 0V terminal and +12V terminal. Or else, severe damage will be done to the indicator.

IX. Analog output

C602 indicator can choose from three Analog output modes: 0 ~ 5V, 0 ~ 10V voltage signal output and 4 ~ 20mA current signal output. The current loop is provided by internal power supply and the current signal can be adjusted to 0 ~ 20mA. The selection of output mode can be done in the jumper JP1 ~ JP3 in power panel, see figure 3-9 for details. In the figure, the jumper position is in conformity with these in power panel and X stands for the position of short circuit ring. The factory setting of current loop is 4-20mA. The output value can be gross weight or net weight by setting SET 1 parameter 1F. The analog output switch is controlled by SET 1 parameter 1E.

Figure 3-9 Setting of Analog Output

Calibration method of Analog output

The zero point value and full range value of analog quantity are proportional to the corresponding DA code (see table 4-3, explanation for SET 1 parameter 11 and 12). Calculation and calibration of parameter 11 and 12 can be done by using the tolerance of Analog output.

Attention: in voltage output mode, short circuit of Analog output terminal is strictly prohibited, so does the connection of load of 4-20mA current output. Or else, damage will be caused to the Analog output circuit.

X. Detection of input and output hardware

When the main display is in the display internal code mode (select 1 for parameter A of

[ AB] in SET 0 ), the detection can be done to check the condition of input and output

[DISP ] terminals. When I0 input terminal signal is effective, the corresponding O0 will have control signal output. For the same reason, the I1 corresponds to O1……I7 corresponds to O7.

Attention: when external equipment is connected, try to avoid using this method to detect input and output circuit so as to prevent any accident.

Under the displaying status of internal code, the indicating lamp for net weight reflects the working status of ARM single-chip computer oscillator in main panel. When the indicating lamp is on, it means that the external quartz resonator is operating normally while the off status of indicating lamp means that the internal RC oscillator within single-chip computer is working.

Data Query and Removal

Method to Save Weighing Data

[ AB]

Set Parameter B in Parameter 9 of SET 1 as 1, the quantitative scale will

[Auto P] automatically save the actual weight of each quantitative cycle. If it is set to 2, then the quantitative scale will automatically save the finishing time and actual weight of each quantitative cycle. The accumulation can’t be performed manually.

Inquiry Method

Press Setting 8 Input 8 Input 8 Input inquire the total accumulated times

8 Input inquiry the total accumulated weight . Press button 6 or 5 during the query.

If the option at right side of lower line shows ’1’, press button Input to print the accumulated times and accumulated weight. If the option shows ‘2’, press button Input to print all weighing records. Press button Exit to end printing weighing record halfway.

The communication port 2 of PC can also be used to read the weighing record.

Accumulated Value Removal

Press button Input after the accumulated value is displayed and the indicator will

[ 0] indicate , which means whether to remove the accumulated data. Press button 5

[dEL ]

8 Input to clear and press Input directly not to clear.

The communication port 2 of PC can also be used to clear the weighing record.

VII. Operation /Stop

Press the button Operation on the indicator panel to start the cycle.

If the button Stop is pressed, the indicator will enter the status of ‘pre-stop’ and the light of

‘stop’ and ‘operation’ will be ON at same time. It will be stopped after the cycle is completed. If the button Stop is pressed once again under the status of ‘pre-stop’, it will enter the ‘pause’ status.

Then the indicator will stop action, all outputs will be shut down and the signal lamp ‘function’ and ‘stop’ will all be OFF. If the button Operation is pressed again, the indicator will be restored

X K 3 1 9 0 C 602 to the running status and continue its work. If the button Stop is pressed repeatedly, the indicator will be switched over between ‘pre-stop’ and ‘pause’; Press button Setting under

‘pause’ status to enter the status of stop, and the status before ‘pause’ will not be saved.

The valid signal (i.e. add voltage of 12V~24V or short connected to ‘+12V’) are input to terminal ‘function’ I1 ,’stop’ I2 on the rear panel, which has same function as button

Operation or Stop .The signal ‘function’ and ‘stop’ will only work at the moment when connected.

Attention: The button Stop , input signal ‘stop’ and its function cannot be used as ‘emergent stop’ of the system.

VIII. One Time Operation

Input the valid signal (i.e. add voltage of 12V~24V or short connected to ‘+12V’) to the terminal ‘material feed’ on the rear panel temporarily. The indicator will start to run after the step of material feeding, and material feeding is started after the signal is valid. The indicator will stop running until the material feeding is finished and it will wait for ‘discharge’ terminal to input the valid signal. After the signal ‘material discharging’ is valid, the indicator will continue to run. The output control signal O5 will be valid after the discharge signal is activated. The discharging action will be finished after the .hopper weight is back to zero zone and the indicator will wait for the new ‘material feeding’ signal. The indicator at these two signal input terminals can be used to realize the synchronized operation with the exterior device or the manually controlled function of the device.

IX. Running after Power Down

If the power is lost during the operation of

quantitative scale

, C602 will memorize the status of program step before the power loss. The indicator will enter the status of pause after the power supply is back. Press button Operation , the indicator will continue the same work before the power loss (but there will be errors in the weight printing data and weighing record in this cycle). If the work before the power loss needs to be ended, the button Setting should be pressed.

X. Buffer Area of Key Command

There is a buffer area of key command with length of 4 in C602. When the key command

X K 3 1 9 0 C 602 with long duration is executed (for example, print the weighing record), the button pressed during the command execution period will be stored in the buffer area of key command. The new key command will be responded only when the current key command is executed.

Notes to working process of additive quantitative scale:

1. The Add Signal is needed before material feeding;

2. The Discharge Signal is needed during material discharging;

3. The condition that the weight should be less than zero value should be satisfied during the process of closing the material discharging.

X K 3 1 9 0 C 602

4. If the Add Signal and Discharge Signal are always valid, the indicator will automatically execute the procedure repeatedly.

Table 6-2 describes the working process of

quantitative scale subtraction by program step.

II. Subtracting scale

X K 3 1 9 0 C 602

Subtracting scale is to control the material (i.e. the material feed) weight discharged by the control hopper. Please refer to Fig 6-2 for the function and the meaning of setting parameters during the process and the sequence order for controlling the input and output:

Figure 6-2 Working Sequence Drawing of Subtracting Quantitative Scale

The parameter instruction in the Figure t0 Measurement delay of material feed t1 Quick feed over delay t2 Slow feed over delay The instrument during the three periods will not judge the weight d1 Quantitative value of feed q1 Quick feed lead of material 1; a1 Slow feed lead of material o1 Allowance of material b2:Min. remaining weight of material; A2:Charging weight of material

Note to working process of subtracting quantitative scale:

1. The Add Signal is needed before material feeding;

2. The Discharge Signal is needed during material discharging;

3. If the Add Signal and Discharge Signal are always valid, the indicator will automatically

X K 3 1 9 0 C 602 execute the procedure repeatedly.

4. If the remaining material weight is less than the min. weight (i.e.d1+d2) of one time material feeding weight plus material in the hopper, the instrument will be stopped to do the material feeding and wait for the Add Signal (it means material charging is allowed, that is, feed material to the hopper); The output control signal of material discharging of the instrument will be valid after there is an Add Signal and it will start to judge the weight. If the material weight in the hopper is added to the weight confirmed by the parameter A2, the material discharging will be stopped and the material feeding cycle which is just stopped will continue.

For example: the batching value of material 1 is 50 kg, the batching value of material 2 is

150kg and the min. remaining weight b2 is 20kg. If the remaining weight in the hopper is less than

70 kg when the cycle is started, the material should be added to the hopper up to over150kg to start the material feeding.

Table 6-2 describes the working process of the quantitative scale subtraction by program step.

Chapter 8 Application Examples of Batching scale

I. Self Control Mode

If belt weighing scale is provided at the control site, the user has to choose three different cargoes of different weights through the belt. The weights of these three cargos are respectively

5kg, 10kg and 15kg and it will be delivered through the belt every 10 seconds. The interval for the cargo to be on and off the weighing platform is about 2 seconds and cargo will be remained at the weighing platform for about 4 seconds. We can set the parameter in SET 2 as follows (suppose that it is 2 decimal digits during calibration)

Fig 8-1 Time Sequence of Catchweigher in Self-control Mode

Brief introduction of control procedure of batching scale in self-control mode (Please refer to the sequence order figure):

(1) The instrument starts to run and it will judge whether the weight is higher than zero zone. If it is higher, then enter t0 delay to wait for the cargo to be completely loaded to the weighing platform;

(2) Time t0 is over and the instrument will start to calculate the average weight of cargo with time interval of t1. The value calculated will be the reference for batching scale signal;

(3) Time t1 is over and the instrument will enter the t2 delay to wait for the cargo to leave the weighing platform;

(4) Time t2 is over and the instrument will send the sorted channel signal to make the cargo enter the corresponding channel;

(5) Sending signal is finished and the instrument will judge whether the weight is back to the zero zone again. Only when the zero zone is entered, would the next cycle be started.

External Control mode

Suppose high speed batching scale is provided at site: Industrial control PLC will combine with the instrument to sort out the cargos quickly. PLC will control the cargo to the weighing platform. A signal will be triggered to the instrument after the cargo is loaded to make the weighing platform calculate the weight. The weight scope of the users’ qualified product is 9.90kg

~ 10.10kg and the channel signal, which can be controlled by PLC to deliver to different channels, will be sent according to the weight scope. The time for one cycle is about 3~5 seconds. The instrument should be used together with PLC. We can set the parameter in SET 2 according to table 8-3 (suppose that there are 2 decimal digits during calibration):

Please refer to Table E-2 for meanings and communication formats of all orders for communication command, among which address represents the address represented by character

A~Z; XH, XL are respectively 4 high bits and four low bits of hexadecimal digits for check sum represented by A~F. In example column, 02H and 03H are respectively start signal and end signal represented in hexadecimal system, the bits between them are ASCII character string, with the last two bits being check sum.

XK3190-C602 communication (2) has eight groups of (non-byte) communication command buffer areas; if all buffer areas are full, later commands may be lost, so continuous command transmission speed of PC should not be too fast.

If there is no data or the data is sent out, return to original command.

Note 5 of Table E-2: Parameter code is same as Note 2. Two ends of data character string are separated by a space respectively, parameter length is limited within 8 characters, parameter value should be in effective range specified in the specifications, or unexpected problem may occur. After all data requiring modification are sent, at last one write command will be sent, which is the command with parameter code WR and without parameter value.

Note 6 of Table E-2: parameter code is same as Note 3, and parameter limitation is same as Note 5. After all data requiring modification are sent, at last one write command will be sent, which is the command with parameter code WR and without parameter value.

Note 7 of Table E-2: the parameter is 1 ASCII character 0, 1 or ?, 1 represents entering remote control state,

0 represents exiting remote control state, ? represents inquiring remote control state. After PC has sent the command of converting to remote control state, if C602 is in stop state, remote control state will be entered; if

C602 is in operation state, this command will be omitted; the returned command parameter is 0.

Note 8 of Table E-2: See Table E-6 for the meaning of NN parameter. Parameter value is represented by 3 digits of integer, indicating 8 digits of binary data. 8 digits of binary data of input and output signal state are relevant to all signals. See E-7 for the content of signal light state.

Annex G Troubleshooting of General Problems

When the instrument work abnormally, if there is any error prompt, please handle it according to A-1 “Explanation of Error Prompt Information”. If the working procedure is abnormal, auxiliary display can be set to work step state ( SET 0 quantitative scale parameter

7B = 4, catchweigher parameter 17B = 4), to observe at which step the action stops. Analyze what conditions for entering next step is not met according to description table of relative procedure step, and then execute corresponding adjustment.

Handling methods of general problems are listed in Table G-1.

Table G-1 Troubleshooting of General Problems

Problem

After power-on, the instrument doesn’t work, the buzzer doesn’t sound.

Reason

The power is off

JP2 jumper wire on main board is in ISP position.

Instrument abnormal

During setting, weighing parameter certain parameters cannot be displayed.

Wiring of transducer is wrong.

Incentive power terminal of four-wire connection is not short connected to corresponding incentive feedback terminal.

Weighing platform or the transducer has problems.

Incentive power load of transducer is too large, making incentive voltage decrease.

This parameter value is wrong, display range. exceeding

Handling method

Check power source

Change JP2 jumper wire on main board or turn K2 switch to RUN position

Check wiring transducer

In case of four-wire connection, EX+ and

SEN+ terminal EX-and

SEN- terminals should be short connected.

Check whether output signals of weighing platform and transducer are normal

The load current of incentive power should not be more than

80mA.

Press 7 8 keys to move flashing position to the parameter, press 5 or 6 to change the parameter.
