proportion:

3000:2.0007=750:X

Where X is the value of the signal expressed in mV/V corresponding

to the theoretical value of the weight of the empty tank. The value

should be about 0.5 mV/V.

Proceed to the calibration described in the following paragraph,

or you can exit the configuration menu by saving the data entered.

The instrument should indicate the value corresponding to the weight

of the empty tank (for example 756.8).

Re-access the configuration menu and enter the weight value read

in the dEad L parameter and enter the value 756.8.

Quit the configuration menu by saving the data.

For greater accuracy, prepare some sample weights or the pre-

weighed material on a certified system and calibrate as described

in the next paragraph.

Installation

Mounting Install the instrument in a location where it will not be subjected to excessive heat, humidity or vibration. For best results, avoid direct sunlight on the front of the instrument. The unit should be installed at eye level so as to allow viewing the display and access to the front panel keys.

Cable Types and sizes

Use a 6 x 0.5 mm

2 shielded cable for the load

cell/s connection. Use a 3 x 0.34 mm2 shielded

cable for the RS-232 connection, and a 2 x 0.34 mm

2 shielded cable for the RS-485 connection.

Power and Wiring Considerations The instrument is powered from an external 24 Vdc source. The instrument can be operated from a computer, therefore, a “clean” power source is required for reliable operation. The incoming power should come from a source that is isolated from other process equipment. Cables carrying primary and switched power should be routed away from load cell and other signal cables to avoid electrical interference. Relays, motor starters and other inductive devices connected to the equipment must have reliable and effective arc suppression. Always connect the shield lead where indicated on the drawing, and on one end only. High voltage devices such as megohmmeters, etc. should never be used to check the wiring connections. Plastic insulating tape should not be used on load cell connections.

Environmental Considerations Heavy electrical equipment should not be installed close to the weighing equipment. Excessive vibration will affect the accuracy of the weigh system and depending on the severity can cause damage to electrical and electronic components. The atmosphere should be dust free and not contain any corrosive gasses or materials which could adversely affect the equipment.

Hazardous areas If the weighing system will be installed in a hazardous area, please refer to the drawing shown on page 42.

NOTES: WELDING on or in the vicinity of the equipment

is strictly prohibited. STATIC loads, caused by thunderstorms, must be prevented from developing by using reliable lightning conductors. ENSURE that the cooling of the equipment is not obstructed.

Introduction

This manual provides general information on the installation, configuration, calibration, and

operation of the Precise 400 Series Digital / Analog Transmitters. There are two models within this series, the Model 400 which features a four-button keyboard, 6-digit Red LED display, and four status LED’s. The Model 450 is a blind unit which can only be configured and calibrated remotely via the serial port. Both models are packaged in ABS Plastic DIN-Rail mounted enclosures.

All units include the following features:

• Drives up to six 350 ohm load cells

• Supports 4 and 6 wire connections

• RS-232, RS-422, or RS-485 outputs

• (2) Logic inputs

• (2) Logic outputs (setpoints)

• Isolated analog output 4/20mA, 0-5 Vdc or 0-10Vdc output utilizing a 16 bit DAC

The Precise 400 Series Transmitters have three different modes of operation:

Operating mode

In this mode the unit displays gross weight, net weight, or peak force readings as required.

Setup mode

This mode is used for configuration and calibration of the unit.

Test mode

The test mode enables you to test the inputs, outputs, and analog output.

Front panel key functions — Operating Mode (Model 400)

The “SET” key enables you to enter values for Setpoints 1 and 2. Press the “SET” key, Set 1 appears on the display. Press the “PRG” key to view the current value. To change the current value, press the “O” key to select a digit, then use the “UP” or “DOWN” keys to increment or decrement the value. Repeat this procedure for the remaining digits, then press the “PRG” key to enter the new value. To change the value for Setpoint 2, press the “SET” key again and repeat the above procedure or press the “O” key to exit.

The “FUN” key is used to switch the unit from Gross mode to Net mode, or Peak Hold mode. To switch to Peak Hold mode, press and hold the “FUN” key until a ‘P’ appears on the display.

Operating Mode (cont’d)

The “O” key is used to zero the unit in Gross mode, tare the unit in Net mode, and reset the value to zero in Peak Hold mode.

The “PRG” key is used to send the data to the RS-232 serial port for use with a computer.

Front panel key functions — Setup Mode

In setup mode three of the front panel keys are used as directional keys to scroll through the various menus. A label on the lower half of each key identifies the direction provided by the key. The “SET” and “FUN” keys are used to navigate through the main menu and sub-menus. They are also used to increment or decrement the numerical value of a selected digit. The “O” key is used to move through certain sub-menu parameters, or to select a specific digit when numerical values are displayed. It is also used to return to the main menu from any of the sub-menus. The “PRG” key switches the unit to the “Basic Configuration” mode. It is also used to enter the sub-menus, and store parameter changes. The “PRG” key when used in conjunction with the “SET” key switches the unit to the “Complete Configuration” mode. It is also used to enter the sub-menus, and store parameter changes.

Status LED’s (Model 400 only)

There are four status LED’s on the front of the unit, one for Motion, one for Net mode, and one for each of the outputs.

Enabling/Disabling front panel keys.

In order to prevent any access to the instrument by non-authorized personnel, a procedure to lock the front panel keys is also available.

Each key can be locked individually. The 1/0 selection establish the lock/unlock condition for each single key.

See page 6 for more details.

Enabling the “blind” function

This function allows to disable the visualization of the display. A dash running counterclockwise on the display’s perimeter is displayed instead of the weight value.

See page 6 for more details.

Main Power Connections

Use terminal 8 for the (+) input, and terminal 9 for the (-) input. The supply voltage must be 24 Vdc + 15%. The external power supply must have a minimum rating of 5 watts.

Transducer/s Connections

Attach cable from transducer/s to transmitter (terminals 13 through 18). If using a 4-conductor cable, (no remote sensing) jumpers must be installed between the + Excitation and + Sense leads (terminals 14 to 15) and between the — Excitation and — Sense leads (terminals 13 to 16) as shown below in Figure 1.

Logic Input Connections

Use terminal 4 for Input (1), and terminal 5 for Input (2). Terminal 6 is the common for both inputs. These are powered inputs, which require an input voltage of 24 Vdc to activate them. See Figure 1 for additional information.

Input (1) is used to zero the unit in Gross mode, tare the unit in Net mode, and reset the peak value when operating in Peak Hold mode.

Logic Input Connections (cont’d)

Input (2) functions as a “send data” command, closing the input causes the weight data to be sent to the RS-232 serial port.

Logic Output Connections

Use terminal 1 for Output (1) and terminal 2 for Output (2). Terminal 3 is the common for both outputs. The outputs utilize solid-state relays with a maximum load rating of 24 Vdc @ 100mA

Analog Output Connections

Use terminal 10 for the 4/20mA output (300 Ohm load max), or terminal 11 for a 0 to 5 Vdc or 0 to 10 Vdc output (10K Ohm load max). Terminal 12 is used as the common for either output.

Serial Output Connections

The transmitters serial port supports RS-232, RS-422 or RS-485 communications. Serial parameter selections can be found on page 19. A detailed description of the serial data formats is provided on pages 21 through 25. Wiring connections are shown on pages 26 through 27.

Configuration Methods

The Precise 400 Series Digital / Analog Transmitters can be configured by using the front panel keys (Model 400) to navigate through a series of menus, or by sending configuration and calibration data to the RS-232 port with

INOVATION an MS Windows based program

included with the unit. INOVATION simplifies the configuration and calibration procedure.

Configuration Procedures

There are two procedures available for setup of

the Precise 400 Series Transmitters, “Basic Configuration” or “Complete Configuration”.

The “Basic Configuration” procedure allows you to change selective parameters, whereas, the “Complete Configuration” procedure allows you to change all of the parameters.

For example, if the transmitter requires calibration only, the “Basic Configuration” procedure is recommended.

The following pages provide a detailed explanation of both configuration procedures.

Basic Configuration via the Front Panel

To perform a “Basic Configuration”, press and hold the “PRG” key until the display shows CAPAC. Use either the “UP” or “DOWN” keys to navigate through the eight basic configuration sub-menus shown below.

Basic Configuration (cont’d)

To set one of the following parameters, CAPAC, SENSIT, NET, DEAD L, DSPDIV, or ANALOG, press the “PRG” key to view the default or previously selected value for that parameter. To change the value, press the “O” key to select a digit, then use the “UP” or “DOWN” keys to increment or decrement the value of the selected digit. When the desired value appears on the display, press the “PRG” key to store the new value. Press either the “UP” or “DOWN” keys to move to the next parameter.

The SIGNAL parameter enables you to view the actual input signal from the transducer/s. Press the “O” key to move to the next parameter.

The CALIBR parameter is used to calibrate the transmitter. The unit can be calibrated using either the data sheet or dead load procedure.

The data sheet calibration procedure allows the transmitter to be calibrated without a transducer simulator or test weights. This procedure is based on the capacity and certified, full scale mV/V output (sensitivity) of the transducer/s.

To perform a data sheet calibration, enter the total scale capacity, sensitivity, net weight, dead load weight, and display resolution, then press the “O” key. The display will indicate STORE ?, press the “PRG” key to save the changes and return to the operating mode.

See page 9 for a detailed explanation of the calibration procedure using test weights. The ANALOG parameter is used to enter the full scale weight value that you want the analog output to represent. The default is net weight value.

To exit from the setup procedure, press the “O” key when any one of the following parameters are displayed CAPAC, SENSIT, … ANALOG. The display will indicate STORE ?, press the “PRG” key to save the changes and return to the operating mode.

Basic Configuration Menu (cont’d)

The Precise 400 Series Transmitters can be calibrated via the front panel keys (Model 400),

or with the INOVATION configuration utility. Both methods consist of the following steps.

• Zero calibration

• Apply a known load (test weight)

• Edit weight value

• Span calibration

• Optional linearization (See page 15)

2-point calibration via the front panel keys

To calibrate the transmitter with the front panel keys, proceed as follows: 1. With the unit in “Basic Configuration” mode and the message “CALIBR” displayed, press the “PRG” key (CAL will be blinking on the display). 2. With the system unloaded, press the “O” key to perform the ZERO calibration.

3. Apply a known load not less than 10% of the net weight value and press the “UP” key.

4. Enter the actual weight value using the “O” key to select each digit, then use the “UP” or “DOWN” keys to increment or decrement the value of the selected digit.

5. Press the “PRG” key to enter the setting (CAL will be blinking on the display).

6. Press the “PRG” key, (the display indicates CALIBR), press either the “UP” or “DOWN” keys to move to the next parameter.

7. If no additional parameter changes are required, press the “O” key (the display indicates STORE ?), press the “PRG” key to save the changes and return to the operating mode. Should it be necessary to erase either of the previous calibration entries, proceed as follows:

When the message CAL is blinking on the display, to erase the zero calibration, press and hold the “FUN” key, and then press the “O” key. Release both keys, the previous zero calibration entry has been erased. To erase the span calibration, press and hold the “FUN” key, and then press the “SET” key. Release both keys, the previous span calibration entry has been erased. End the procedure as described above (points 6 and 7).

NOTE: Input signal from the transducer/s must be stable when entering the zero and span values.

Configuration using INOVATION

To configure the Precise 400 Series Digital /

Analog Transmitters with the INOVATION program, proceed as follows:

1. Install INOVATION on an IBM-compatible computer running Windows 95, 98, Me or XP.

2. Minimum system requirements are 8MB of extended memory and at least 5MB of available hard drive space.

3. Remove power from both units, and connect the PC’s serial port to the RS-232 terminals on the transmitter. Refer to page 27 for wiring.

4. Apply power to the PC and the transmitter,

then start the INOVATION program.

5. Switch the transmitter into remote mode by removing the upper left cover and moving jumper (J1) to the remote control position as shown below. The Model 400 can also be switched into remote mode by going into complete configuration and then selecting ‘Remote’ from the serial menu. See page 19.

Pins 1 — 2 = Remote Control Pins 2 — 3 = Default Setting

When viewing either model from a computer, the current weight value will be displayed under the icon representing the unit being configured. If ERROR appears under the transmitters icon, re-check all of the wiring connections, verify that the unit is in remote mode, and make sure the icon being displayed matches the address of the transmitter to be configured. Double-clicking on the transmitters icon will bring

you to the INOVATION Main Setup Screen.

Configuration using INOVATION (cont’d)

On this screen you can switch the display among net, gross and peak reading, set the se-rial address, enter values for the two setpoints, check the two logic inputs status and the software release of the instrument.

Click on the SETUP button, seven file folders will appear on the lower half of the screen. The first file folder labeled “Parameters” will be open.

The top section in this folder is for entering the total scale capacity, sensitivity, net weight, and dead load weight values (required parameters for performing a data sheet calibration)

The data sheet calibration procedure allows the transmitter to be calibrated without a transducer simulator or test weights. This procedure is based on the capacity and certified, full scale mV/V output (sensitivity) of the transducer/s.

To perform a data sheet calibration, enter the above values, then click on the SEND button for that group of parameters.

The next section in this file folder is used to select the display resolution. It consists of a drop down menu and a SEND button.

The Precise units allow to count by 1’s up to 60,000 counts, Yet, for values greater than 10,000, the units automatically select a lower resolution to ensure greater stability. After se-lecting the desired resolution, press the SEND button for this parameter. Do not press any of the other SEND buttons in this folder or the unit will revert back to a default setting of x2, x5, etc.

Changes to the display resolution should only be done after the unit has already been calibrated using the data sheet or dead load procedure.

The bottom parameter selection in this file folder is labeled “Operating Mode”. It enables the unit to retain the mode of operation in the event of a power loss. When the power is re-applied, the transmitter automatically returns to the mode that it was operating in prior to the power loss.

Changes to the Operating Mode cause an automatic power off — power on sequence of the instrument when the configuration will be saved. This allows the new Operating Mode to take effect.

The second file folder enables you to calibrate the unit with a transducer simulator or actual weight, (recommended method of calibration).

Inside this 2nd file folder, once the zero calibration has been performed, the program asks the operator if the new zero has to modify the “Data sheet” calibration.

Figure 2

If the operator answers “Yes”, the “Dead load” value inside the first file folder will change automatically according to the new zero. If the operator answers “No”, the “Dead load” value inside the first file folder will remain set to the previous value.

The third file folder contains the parameter selections for digital filtering, zero tracking, etc.

The fourth file folder contains the parameter selections for configuring the inputs and outputs

The fifth file folder contains the parameter selections for the serial output.

The sixth folder contains the parameter selections for the analog output,

The seventh folder provides a means for testing the outputs and analog output

The Main Setup Screen and file folders 1 through 6 all have SEND buttons on them for downloading the various parameter changes.

When configuration and calibration has been completed, the data can be saved on a PC or floppy disk or downloaded (sent) to the transmitter. This method of configuring and calibrating is very beneficial when several transmitters with similar configurations are being set up, or when a transmitter has to be replaced.

To exit INOVATION, click on the Exit Setup icon. Now click on Option in the upper left corner of the screen, from the drop down menu select EXIT, a “Save Changes” window will appear, click on OK. This will return you to the Configuration Utility Screen, click on QUIT. Figure 2 shows an example of one of the

INOVATION configuration screens.

Page 12: Precise DAT400 (3)

Figure 2.1

The Inovation software also allows the operator to create new configurations,

save new files and open existing files wi-thout having any instrument connec-ted to the computer.

Thanks to this feature, the download of a given configuration to the instrument can be performed at any time.

To perform the operation mentioned above click on the “Edit” menu at the left end upper corner (See figure 2.1), then enable the function “Edit Configuration Offline”. The message “Edit” will appear on the display, showing this particular condition.

Another useful function concern the possibility to print out a report in which all the parameters of a given configuration are included. The “Print” command can be performed by clicking on “Print Configuration”.

Besides, the command “Report Notes” allows the operator to include a heading in the report, in order to identify the plant, the customer name or any other useful information.

An example of a printed report is given on the right side of this page:

NOTE: Prior to calibration, the transmitter must be configured, thus giving it a set of operating parameters. The unit can be calibrated using the 2-point method or the optional multi-point (linearity compensation) method. See page 15 for a detailed description of the multi-point calibration procedure.

2-Point calibration via the front panel keys

To calibrate the transmitter using the front panel keys, proceed as follows: 1. With the unit in “Complete Configuration” mode, press either the “UP” or “DOWN” keys until CALIBR is shown on the display. 2. Press the “PRG” key (CAL will be blinking on the display). 3. With the system unloaded, press the “O” key. 4. Apply a known weight not less than 10% of the net weight value and press the “UP” key.

5. Enter the actual weight value using the “O” key to select each digit, then use the “UP” or “DOWN” keys to increment or decrement the value of the digit. Press the “PRG” key to enter the setting (CAL will be blinking on the display). 6. Press the “PRG” key, (the display indicates CALIBR), press either the “UP” or “DOWN keys to move to the next parameter. 7. If no additional parameter changes are required, press the “O” key (the display indicates STORE ?), press the “PRG” key to save the changes and return to the operating mode. Should it be necessary to erase either of the previous calibration entries, proceed as follows: To erase the zero calibration, press and hold the “FUN” key, and then press the “O” key. Release both keys, the previous zero calibration entry has been erased. To erase the span calibration, press and hold the “FUN” key, and then press the “SET” key. Release both keys, the previous span calibration entry has been erased.

Complete Configuration Menu (cont’d)

The Model 400 features a 10-point linearization option (available only with the front panel keys). Any number of points up to 10 may be used, however, the last point must always be the full scale value of the weighing system. Example: A one point linearization correction would require a total of two points, one point within the range, and one point for full scale.

Prior to performing the linearization correction, at least the zero of the unit must have already been calibrated, while the full scale value is not mandatory. The unit must be in CALIBR mode, and you should have known weights available equal to the points being set.

Multi-point Calibration via Front Panel Keys

1. With the unit in either “Basic or Complete Configuration” mode, press the “PRG” key (CAL will be blinking on the display). 2. Press and hold the “SET” key until Lin P1 is blinking on the display. 3. Apply a known weight for the first linearization point, and press the “PRG” key. 4. Enter the actual weight value using the “O” key to select each digit, then use the “UP” and “DOWN” keys to increment or decrement the value of the selected digit.

5. Press the “PRG” key. The unit will increment to the next linearization point (Lin P2). 6. Repeat steps 3 through 5 for additional points. 7. If all 10 points will be linearized, follow the 1st. procedure. For linearization correction using less than 10 points, follow the 2nd. procedure.

1st Procedure (10-point linearization) 7a. Enter the weight value for linearization point Lin P9, and press the “PRG” key (CAL will be blinking on the display). Press the “PRG” key again, (the display indicates CALIBR). 7b. Press the “O” key (the display will indicate STORE ?), press the “PRG” to save the changes and return to the operating mode.

2nd. Procedure (less than 10-point linearization) 7a. The last linearization point must be the full scale value. Press the “O” key, (CAL will be blinking on the display). 7b. Press the “PRG” key (the display will show CALIBR). Press the “O” key (the display will indicate STORE ?). 7c. Press the “PRG” key to save the changes and return to the operating mode.

Baud Rates

2400, 9600, 19200, 38400, and 115200

Data Formats

All serial characters are in ASCII format, and consist of the following. 1 Start Bit, 7 or 8 Data Bits, 1 or 2 Stop Bit, Parity No, Even or Odd. The above data depend on the selection made in the “SERIAL” menu (see Table 3 on page 28)

Transmission of the serial data can be initiated in several ways as described below.

Automatic mode

The “Automatic” mode is used to interface with printers or other data acquisition devices. The serial data is transmitted automatically, upon stabilization whenever the weight value has increased or decreased more than 20 divisions. This function is not performable when the “MOTION” parameter is set to 0 (weight stability check disabled).

Continuous mode

The “Continuous” mode is used to interface with computers, remote displays, or other types of devices that require constant data updating.

Demand mode

The “Demand” mode is used to interface with printers and requires a manual print command from the front panel keys (Model 400) or a remote contact closure to initiate the output. In the above modes, the transmitter sends serial data using the format shown below:

Serial Communication

STX <status> <net weight> <gross weight> <peak value> ETX <chksum> EOT

STX (start of text) = 02h ETX (end of text) = 03h EOT (end of transmission) = 04h

NOTE: The brackets “<“ “>“ are not sent, they are only shown for clarification. The checksum control value is obtained by performing the XOR operation. It is expressed with 2 Hexadecimal digits. Example: 25 = 1D The result of the above calculation equals 1 character, which can be a numerical value of 0 to 9 or A to F (Hexadecimal)

“S” “M” “O” “E”

= 1 ASCII character consisting of the following: = Stable = Motion = Overload = Error = 6 ASCII characters = 6 ASCII characters = 6 ASCII characters = 2 ASCII characters (STX & ETX are not included in the checksum)

<status>

<net weight> <gross weight > <peak value> <checksum>

Page 22: Precise DAT400 (3)

22

Serial Communication (cont’d)

After receiving the request, the transmitter responds with the following data string.

Slave mode

The slave mode is used for interfacing with distributed control systems (DCS) or programmable logic controllers (PLC). This mode requires a data request from the master to initiate the output.

In this mode the host sends serial data to the transmitter using the formats shown below:

<addr> <gross weight> <net weight> <peak value> ETX <chksum> EOT <status>

In case of an error, the transmitter will respond with the following data string.

<addr> NAK EOT

<addr> serial address + 80h Example: address 1 would be 1 + 80h = 81h ETX (end of text) = 03h EOT (end of transmission) = 04h

“N”

“S” “M” “O” “E”

= 1 ASCII character consisting of the following: = Stable = Motion = Overload = Error = 6 ASCII characters = 6 ASCII characters = 6 ASCII characters = 2 ASCII characters (<Addr> & ETX are not included in the checksum)

<status>

<net weight> <gross weight > <peak value> <checksum>

Character strings

NOTE: The brackets “<“ ”>“ are not sent, they are only shown for clarification.

The checksum control value is obtained by performing the XOR operation.

It is expressed with 2 Hexadecimal digits. Example: 25 = 1D

The result of the above calculation equals 1 character, which can be a numerical value of 0 to 9 or A to F (Hexadecimal)

Programming the set-points

<addr> <s2> ETX <chksum> EOT <s1> “S”

Command from the host

<s1> <s2>

= 6 ASCII characters for set-point 1 = 6 ASCII characters for set-point 2

In case of an error, the transmitter will respond with the following data string.

<addr> NAK EOT

The programmed values are stored in RAM, however, they are not retained if the power is removed. There is no limit on the number of times that these commands can be performed.

The transmitter responds with the following data string:

<addr> ACK EOT

<addr> “N” EOT

Page 23: Precise DAT400 (3)

23

This command is used to store the programmed set-point values in Eeprom. This command can be performed up to 100,000 times.

Store set-point values in Eeprom

In case of an error, the transmitter will respond with the following data string.

<addr> NAK EOT

<addr> EOT “M”

The transmitter responds with the following data string:

<addr> “M” EOT

Request set-point values

In case of an error, the transmitter will respond with the following data string.

<addr> NAK EOT

<addr> EOT “R”

Command from the host

The transmitter responds with the following data string:

<addr> <s2> ETX <chksum> EOT <s1> “R”

“Net mode” / ”Gross mode” switch command

This command performs the same function of the “FUN” key.

Switch to Gross weight mode

Command from the host

<addr> “L” “C” EOT

The transmitter responds with the following data string:

<addr> “L” “C” ACK EOT

In case of an error, the transmitter will respond with the following data string.

<addr> NAK EOT

Page 24: Precise DAT400 (3)

24

Modbus mode The Modbus mode is used to communicate with Modicon Programmable Controllers using a unique message structure that the controllers can understand regardless of the type of networks being used. Please refer to the tables on pages 31 through 41 for information regarding the MODBUS RTU Protocol Specifications. Modbus® and Modicon® are registered trademarks of the Schneider Automation Group.

Switch to Net weight mode

Command from the host

<addr> “N” “C” EOT

The transmitter responds with the following data string:

<addr> “N” “C” ACK EOT

In case of an error, the transmitter will respond with the following data string.

<addr> NAK EOT

Zero / Tare / Peak reset command

This command performs the same function of the “0” key and/or logic input (1). It’s used to zero the unit when in Gross mode, tare the unit when in Net mode, and reset the value to zero when operating in Peak Hold mode.

Command from the host

<addr> “A” “A” EOT

The transmitter responds with the following data string:

<addr> “A” “A” ACK EOT

In case of an error, the transmitter will respond with the following data string.

<addr> NAK EOT

Page 25: Precise DAT400 (3)

Print mode

This protocol enables the communication with a printer. The data on the printed report are the follo-wing: NET, GROSS and TARE (+ PEAK, if enabled).

The print command takes place by pressing the PRG key or by activating the remote input #2. (*) The printed report is issued only if the following conditions are met:

• Gross weight positive

• Net weight positive

• Stable weight (**)

• BLIND function disabled (***)

(*) In case the PRG key is locked (see page 6) the print command can take place through the remote input #2 only.

(**) The weight stability condition is controlled only if the “MOTION” parameter (see page 16) is set

to a value ≠ 0. If MOTION = 0 the printed report is issued even if the weight is unstable..

(***)In case the BLIND function is enabled (see page 6) the print command can take place through the remote input #2 only, not via the PRG key.

Between one printout and the next one the weight must change for at least 20 counts.

NOTES: 1. The hysteresis setting must be less than it’s respective setpoint value. Entering a hysteresis setting greater than the setpoint value will automatically be replaced with a default setting of (2) counts. 2. Hysteresis settings of within 10 counts of their respective setpoint values are possible, however, much smaller values are normally sufficient. 3. A large hysteresis setting (4,990 counts) could be used as follows: Setpoint 1 is used to fill a vessel with 5,000 lbs. of product, and setpoint 2 will be used as a high weight alarm. When the weight in the vessel reaches 5,000 lbs., relay # 1 de-energizes stopping the flow, feed, etc. The product is drawn from the vessel as required, when the weight in the vessel reaches 10 lbs., setpoint # 1’s relay re-energizes and automatically refills the vessel to 5,000 lbs.

MODBUS RTU PROTOCOL SPECIFICATIONS

3. LIST OF FUNCTIONS SUPPORTED

The Modbus protocol writes directly into the memory of the instrument.

Use caution when sending data to the instrument: The data being sent must be within the specified ranges given in the tables on the following pages.

Some of the data is written into the E2prom’s memory (refer to the column in the tables “Stored in E2prom”) for additional information. This memory can only be written to 100,000 times, therefore, you should avoid writing continuously into this memory.

To confirm the storage of a new value in the E2prom, perform the MAKE — BACKUP function. If this function is not performed, all of the newly stored data will be lost when power is removed from the instrument.

The “Set point” setting does not require the MAKE — BACKUP function to be performed.

The set point values are expressed as number of divisions This means that any set point value (temporary or permanent) has to be multiplied by the “Display division” data, in order to obtain the actual value of the set point. E.G. Assuming that the “display division” value is 0.2; if the PLC asks for a set point value and get the data “3949” from the instrument, this means that the actual value of the set point is 789.8 (3949 x 0.2 = 789.8)

Even the other weight values are given as number of divisions, except for the “Net weight” and “Gross weight”.

“Net weight” and “Gross weight” (Modbus addresses 40006 and 40007) are given as absolute values Note: The numeric values on the following pages for (addresses, codes, and data) are represented as decimal values. The addresses given in the following tables refer to the standards provided in the Modicon Modbus Protocol Reference Guide PI-MBUS-300 Rev J.

2. DATA FORMAT

• Start Bit : 1

• Data Bits : 8, the Least Significant Bit (LSB) is sent first.

The response time for most data requests is within 20 milliseconds. Exceptions:

• E2prom Backup command (Maximum time = 350 milliseconds)

• Writing of the following registers: Load cell/s total capacity, load cell/s sensitivity, Net weight, Tare weight, and Filter (Maximum time = 550 milliseconds).

4. INSTRUMENT RESPONSE TIME

4.1 RESPONSE TIME WHEN CONNECTING SEVERAL SLAVES

Single twisted pair

Query Master to slave 01 Response time slave 01 Response slave 01 20 mSec delay Query Master to slave 02

Double twisted pair

Query Master to slave 01 Response time slave 01 Response slave 01 delay Query Master to slave 02

With a baud rate of 19200 Time = 15 to 20 milliseconds

Each single function is explained in detail on pages 34, 35 and 36 of the operator’s manual.

Each function is composed by a Query (request master instrument) and a Response (answer instrument master). Queries and responses are composed by a sequence of data that

are briefly explained here below (***), please note that the code “0x” before any value indicates that the value is represented as hexadecimal value.

Besides, all the Modbus addresses (the ones mentioned in the left end column on pages 38 and 39) have to be represented as hexadecimal values, but, only for these addresses, there is an im-portant rule to be taken into consideration:

Before converting the address into an hexadecimal value, the 1st digit on the left has not to

be considered and the remaining 4 digits have to be decremented by “1”.

1st Example:

To represent the address 40150 (“display division” on page 38) as hexadecimal value, exclude the digit “4” (remains “0150”), then decrement by 1 the number “0150”. The result is “0149”, now perform the conversion into hexadecimal. The result is “00 95”. This is the value to be used in the query.

2nd Example:

To represent the address 40102 (“load cells sensitivity” on page 38) as hexadecimal value, exclude the digit “4” (remains “0102”), then decrement by 1 the number “0102”. The result is “0101”, now per-form the conversion into hexadecimal. The result is “00 65”. This is the value to be used in the query. (***)

Address: is the number of the instrument’s address, represented as hexadecimal value (in this case do not decrement by 1 the number).

Function: is the number of the function to be performed (see the table above) 1st Output address: is the address number where the reading of the outputs status has to start

Number of outputs: is the number of the outputs to be read 1st Input address: is the address number where the reading of the inputs has to start

Number of inputs: is the number of the inputs to be read Number of bytes: represents the number of bytes which compose a data 2 byte CRC: “Cyclical Redundancy Check”. It’s an algorithm used as checksum. Total byte: Total number of bytes transmitted. This data is not included in the strings.

6 BROADCAST MODE

The communication strings are controlled by the CRC (Cyclical Redundancy Check). If a communication error occurs, the slave unit doesn’t answer. The master unit controls a timeout when waiting for the response from the slave. If the slave doesn’t answer during this timeout, it means that a communication error has occurred.

The Modbus address 40008 is composed by 2 bytes. The conversion of these 2 bytes from hex into binary gives the meaning of each single bit described in this table.

E.g.

if the bytes in the address 40008 are 24 85, the conversion into binary gives the sequence of bits

100100 10000101. The digit at the right hand side matches with the 1st bit (Net weight polarity), therefore the values given in the above mentioned example are equi-valent to:

Net weight polarity = 1 = negative Gross weight polarity = 0 = positive Weight stability = 1 = yes Millivolt polarity = 0 = positive Underload condition = 0 = no Overload condition = 0 = no Off range condition = 0 = no Preset tare condition = 1 = yes Input 1 status = 0 = de-activated Input 2 status = 0 = de-activated Relay output 1 status = 1 = activated Relay output 2 status = 0 = de-activated Scale unloaded = 0 = no Keyboard status = 1 = locked

PrecisePrecisePrecisePrecise™ 24 Volt Power Supply

Installation

• Make sure the installation complies with local regulations and electrical codes.

• Connect AC voltage to the terminals marked “L” and “N”.

• The DC voltage is available on the terminals marked “+” and “-”. The second set of terminals are used when powering two transmitters from a single power supply (See notes).

• A red LED is illuminated when the power supply is “ON”.

Notes: The power supply should be used to power two transmitters only when a single load cell is connected to each transmitter. For multiple load cell applications it is recommended that an individual power supply be used for each transmitter. This enables the power supply to compensate for any fluctuations in the incoming line voltage. Recent field experiences have shown that voltage drops of greater than 10% can cause the transmitters to drift and become unstable.
