OMMISSIONING
PRECAUTION: Please read this manual carefully before energizing the indicator. Perform the commissioning operation according the procedure given here. Use trained personnel for cleaning, commissioning, checking and service of the indicator. The interference of untrained personnel may cause some unwanted damages or injures.
Note:
In this manual the term “Digital Load Cell“ will be refered to “DLC“.
4.1 Mechanical Installation
First of all please determine the place where your indicator can operate safely. This place should be clean, not getting direct sun light if possible, with a temperature between -10 ºC and +40 ºC, humidity not exceeding 85% non-condensing. Take care to the housing dimensions and the suggested panel hole dimensions given in chapter 3.5. All the cables should be installed safely to avoid mechanical damages.
To avoid electrical noise protect your indicator which has very low input signal level from the equipment that produces electrical noise, especially in panel mounting.
4.1.1 Jumpers
There are three jumpers on the instrument’s main board/weighing board for calibration and for switching on/off.
To change the position of this jumpers, open the housing and perform the necessary changes before energizing the indicator.
J8 On/Off Switch
(always short circuit at the Panel type)

Figure 4.2 The pin layout of the DC connector
The quality of the instrument’s ground will determine the accuracy and the safety of your indicator. A poor ground can result in an unsafe condition if an electrical short cuircuit happens. A good ground connection is needed to minimize extraneous electrical noise pulses. It is important that the instrument does not share power lines with noise-generating equipment such as heavy load switching, motor control equipments, inductive loads, etc. If the condition of the power line in the plant is bad, prepare a special power line and grounding.
If you have to service the indicator, turn off the power and wait at least for 30 seconds before interfering.
All connectors are at the rear side of the housings of desk and panel types. The stainless steel housings must be opened to make the required connections. These connections must be done as described below.
FT-12 Technical Manual, Rev. 1.35 November 2010
Page 10 of 44
4.2.2 Standard Load Cell Connection
The load cell wiring should be made carefully before energizing to avoid damages to the weight indicator and the load cells. The input resistance of the load cells that you want to connect should be more than 58
Ω.
The sense pins of the instrument should be connected. In 4-wire installations the sense and excitation pins with the same polarity should be short circuited at the connector side.

6.2 Application Programmes
Besides basic weighing the FT-12 indicator can be used in different common applications such as check weighing (over/under), peak hold, dynamic weighing (animal weighing) and automatic filling.
The status LEDs located at the left side of the display and the digital I/O have different meanings according to the selected application mode. The meanings and the structure of the digital I/O are given in chapter 10.
6.2.1 Basic Weighing
This is the convenient application mode for general weighing applications. The FT-12 weighing indicator can be used in both single range and dual range scales. In the basic weighing mode the weight data can be printed on a label, together with header and footer.
FT-12 has also the capability of totalizing sequential weights, 99 preset tare memories, 99 alphanumerical ID memories and 9 groups of setpoint memory
– each setpoint group has 3 outputs. If an alphanumeric header of an ID and/or an alphanumeric ID data has been downloaded to FT-12, the alphanumeric name of this ID can also be printed together with an alphanumeric ID header. Please see the “Memory Operations” in chapter 7 and the print examples in chapter 9.2.
6.2.2 Check Weighing
This application mode is used to compare the weight of the load placed on the pan with the predefined target plus/minus tolerance values. FT-12 can store 9 set point groups, each includes three different set points. In this way the target and tolerance values for 9 different items can be stored within FT-12 and the selection of these items can simply be done by keys.

The nominal target value and tolerance data will be entered as given below:
WT (Target weight) = SP1 Tolerance T1 = SP2 Tolerance T2 = SP3
If only one tolerance is needed, so T1 is the right choice (T2 has to be adjusted to a high value respective it has to be ignored).
In the check weighing mode the weight value must be above a threshold value (parameter [101]) for activating the outputs. When the weight exceeds the threshold value, the weight monitoring process starts automatically.
The keys are locked and the weighing result is annunciated to the status LEDs and/or digital outputs.

6.2.3 Peak Hold
The peak hold mode is generally used in compression, tension and tearing test applications. The force is monitored and the maximum value is hold on the display. First the threshold value (parameter [101]), the ending rate (parameter [102]) and the alarm value (parameter [104]) should be defined in the setup mode (see chapter
6.3.6). The peak hold process starts by pressing the <Start> key. The output no.2 activates which means the peak hold process is running. Until the force reaches the threshold value (parameter [101]), the message [LoAd] and the applied force are shown on the display sequentially. In this period the force is not monitored to hold the peak value. After reaching the threshold value the [LoAd ] message will disappear, the force is now being monitored and the maximum force value is displayed. If the force decreases more than the rate entered as the ending rate (parameter [102]) the peak hold process ends. Output no.2 deactivates again. Now output no. 3 activates, which means the peak hold process has finalized. The [PEAK ] message and the peak value are shown on the display continuously. If the auto print function has been activated (parameter [046] = “1”) the test result will be automatically printed. The <Reset> key can be used to stop the process. If the force exceeds the value entered as alarm value (parameter [104]) the process automatically stops and the [ ovEr] message
FT-12 Technical Manual, Rev. 1.35 November 2010
Page 15 of 44
appears on the display. An alarm condition can be stopped by pressing the <Reset> key. Starting or resetting the peak hold process can be also be done by a digital input.
6.2.4 Dynamic Weighing
The dynamic weighing mode generally is used for weighing unstable objects like animals. First the threshold value (parameter [101]) and the time parameter (parameter [103]) should be defined in the setup mode (see chapter 6.2.6).
If the weight value is above the threshold value, dynamic weighing will be started by pressing the <Start> key or applying a digital start input. The [------] message is shown on the display. After the pre-defined time delay
(minimum 5 s) the [End ] message and then the weight value are shown on the display. If the auto print function has been activated (parameter [046] = “1”) the weighing result will be automatically printed. The dynamic weighing process can be stopped by pressing the <Reset> key or by activating the digital input no.3.
6.2.5 Filling
The filling mode is used for automatic filling applications in gross or in net. FT-12 can store 9 setpoint groups with three different setpoints for each. By this the target weights, the coarse feeding values and the fine feeding values for 9 different items can be stored within FT-12 and the selection of any items is simply done by keys.
Target weight, coarse and the fine feeding values will be entered as setpoints as shown below.

SP2 = Fine feeding value If the actual weight value gets closer to the target value than the value defined here, the filling turns into fine feeding.
SP3 = Preact value If the actual weight value gets closer to the target value than the value defined here, the filling ends.
The threshold value (parameter [101]) is used for the tare control. If the weight is higher than this threshold value the filling process starts by pressing the <Start> key or by applying a digital start input. If available and after taring the coarse feeding output (output no.1) and the fine feeding output (output no.2) activate. After reaching the fine feeding value (SP1-SP2) the coarse feeding output (output no.1) deactivates. After reaching the preact value (SP1-
SP3) the fine feeding output (output no.2) deactivates. Now the “End Of Filling” output
(output no.3) activates which indicates the end of the filling process. If the auto print function has been enabled
(parameter [0
46] = “1”) the weighing result will be automatically printed. After unloading the scale the “End Of
Filling” output (output no.3) deactivates again and the indicator becomes ready for the next filling cycle.

6.5 Scale Calibration
[3--] Calibration Block
[30-] Calibration
[300 ] Gravity
This parameter should be used in the scale that will be verified in two stages by gravity adjustment (in legal metrologic applications). This parameter should not be touched in other applications.
If you enter a value in this parameter before calib ration (as six decimal digits, e.g. enter “798564” for
“9.798564”), this value will be assumed as the reference gravity acceleration where the initial calibration has been performed. After the initial calibration this parameter will be automatically set to
“0”.
If the value of this parameter is “0” this means no gravity adjustment has been performed after the initial calibration.
In the second stage of the verification the gravity acceleration of the place where the weighing indicator will be used should be entered (as six decimal digits, e.g. enter “800065” for “9.800065”).
Exit setup by saving the changes without entering the calibration (parameter [301]).
[301 ] Calibration with Test Weights
Begin the calibration by pressing <Enter>.
Unload the scale when the displays shows [ZEro.CA] message and press <Enter>.
The display will show the
[WAıt ] message during the zero calibration. In this period the scale must be unloaded and stable.
Approximately 10 seconds later the display will show [LoAd ] and then [ XXXXXX ].
The value shown on the display is the weight that should be used for the span calibration. If the value of the test weight which will be used is different from the value shown on the display, type the new value by
<Tare> and <Zero> keys, place the test weights on the scale and press <Enter>. Any test weight should be at least 10% of the scale capacity or higher.
The display will show the
[WAıt ] message during the span calibration. Approximately 10 seconds later the display will show the [SAvE ] message. You can save the calibration by pressing <Enter> or quit without saving by pressing the <F> key.
[31-] Adjustment
In this sub-block you can only perform zero adjustment or span adjustment without doing a full calibration.
[310 ] Zero Adjustment
This parameter is only used for refreshing the zero level of the scale to prevent wrong weighings due to zero drifts. Begin the zero adjustment by pressing <Enter>. Unload the scale when the displays shows the [ZEro.CA] message and press <Enter> again.
The display will show the
[WAıt ] message during the zero adjustment. In this period the scale must be unloaded and stable. Approximately 10 seconds later the display will show the [SAvE ] message. You can confirm the “Save zero adjustment” by pressing <Enter> or cancel it by pressing the <F> key.
[311 ] Span Adjustment
This parameter lets you perform the span adjustment. By pressing the <Enter> key [XXXXXX] appears on the display. The displayed value is the weight that should be used for the span adjustment. If the value of the test weight that will be used is different from the value shown on the display, then type the new value by <Tare> and <Zero> keys, place the test weights on the scale and press <Enter>.
The display will show the
[WAıt ] message during the span adjustment. Approximately 10 seconds later the display will show the [SAvE ] message.
You can confirm the “Save span adjustment” by pressing
<Enter> or cancel it by pressing the <F> key.
[312 ] Span Adjustment Under Load
This parameter is being used to perform span adjustment of a scale without lifting the load from it. This operation is especially used for span adjustment of filled tanks. You can make span adjustment without removing the load in the tank.
When you press the <Enter> key the [P.ZEro ] message appears on the display. This means the scale will take the current load as a temporary zero. After getting ready for this level, which means temporary zero adjustment, the <Enter> key should be pressed. The display wi ll show the [WAıt ] message during the temporary zero adjustment. After this step the display will show [LoAd ] for a certain period and then [
XXXXXX ]. The value shown on the display is the weight that should be used for the span adjustment. If the value of the test weight which will be used is different from the value shown on the display, type the new value by <Tare> and <Zero> keys, place the test weight on the scale and press <Enter>. The display

PERATIONS
7.1 ID Memory
FT-12 has two ID codes and the capability to assign clear-text names to them for print out. There are also 99 ID memories which can be shared between the two IDs in any way. The IDs can either be entered via related keys or can be downloaded via serial port in host mode (e.g. by using the FLINTEC IndFace software).
To call any ID from the memory you have to press the <F> key and then the <ID1> or <ID2> key.
Now the [ıd --] is prompted. Enter the ID code (from 1 to 99) and confirm with <Enter>.
After selecting the desired ID, the indicator will return to the weighing mode. If you want to return to the weighing mode without calling any ID, you can simply press the <F> key while the [ıd --] is prompted.
After calling any ID from the memory, you can print the alphanumeric ID code on the printout. (see parameter
[043] and [044]). If you download ID headers to FT-12, the alphanumeric ID headers can be printed instead of the default ID headers.
7.2 Preset Tare Memory
99 numerical tare values can be stored within FT-12 and can be recalled at any time as preset tare.
To store a numerical tare value into the memory you have to press the <M> key first, then the [MeMorY] is prompted on the display. You need to press the <PT> key. The [PtN 1] message will appear on the display which means that you have reached the 1 st
code of the preset tare memory. You can directly enter the code number of the desired preset tare or you can search for the preset tare code by <
>
and
<
>
keys.
After finding the desired code you can access it by pressing <Enter>. The preset tare value is now shown on the display. Enter the the new preset tare value with numerical keys, then confirm with <Enter>. Now you come to the next tare code. Pressing the <F> key will be enough to return to the weighing mode.
For taring with any preset tare value from the memory you have to press the <F> key first, then the <PT> key.
Now the [Pt --] code is prompted on the display. You should type the related preset tare code (from 1 to 99) with numerical keys and confirm with <Enter>. The chosen preset tare value will be shown on the display for a short period, then the indicator tares the scale and the net weight is shown on the display.
You can return to the weighing mode without selecting any preset tare code by pressing the <F> key.
If the selected tare code is empty, the [EMPtY] message will appear on the display. If the tare value is zero or greater than the scale capacity, the [Err Pt] message appears on the display. The messages can be confirmed by pressing <Enter> and new values can be entered.
7.3 Setpoint Memory
FT-12 has 9 setpoint groups with 3 setpoint values for each. The setpoints can only be used by selecting from the memory. Therefore the setpoints have to be stored to the memory first.
First you need to press the <M> key to store the setpoints to FT-12. If you press the <SP> key while the
[MeMorY] message is shown on the display the [SPN xx] will be displayed. Here the first digit is the group number; the second digit is the setpoint number in that group. For example [SPN 12] means the 2 nd
setpoint of the 1 st
group. Here you can search between setpoints by <
>
and
<
>
keys and confirm the desired setpoint with <Enter>. The selected setpoint number and the setpoint value will be shown on the display sequentially.
After entering the new setpoint value with numerical keys, you can confirm the entered value and go to the next setpoint by pressing <Enter>. By pressing the <F> key you return to the weighing mode without making any changes.
To call a setpoint group from the memory, you have to press the <F> and <SP> keys sequentially.
The [SP -] message will appear on the display. Here you have to enter the setpoint group number (from 1 to
9) and confirm it with <Enter>. The setpoints in the group will be shown on the display sequentially with setpoint numbers and the indicator will return to the weighing mode. You can also return to the weighing mode without selecting a setpoint group by pressing the <F> key.

ECORDS
If the alibi memory is installed and activated, the indicator keeps the latest 149 764 weighing records in this memory. The recorded data can be viewed on the indicator’s display or exported via serial port.
To find a definite record you have to enter parameter [802]. After reaching the desired record, the recorded data can be viewed in the display. If needed you can print this record together with the following 9 records by pressing the <Print> key. If you press the <Print> key in parameter [803], all recorded data will be sent via serial port. The <F> key cancels the print job.
Empty fields will be printed as “------“ , corrupted records as “xxxxx” . For the records for which weighing results cannot be given, the message “no rec” will be shown on the display.
If the alibi memory is activated, the alibi record number is also found on the print out data.
After installing the alibi board or changing the main board “Error 41” or “Error 42” will be shown on the display after power on because the activation of the alibi memory is required.
If the calibration jumper is short circuited, you can activate the alibi board by pressing the <Enter> key after power on. Otherwise the alibi errors will disappear by pressing the <Enter> key, but you cannot export any data
(Error “43” will be shown after pressing the <Print> key ).

9.2.3 Continuous Output Mode
The continuous output mode allows for a fast and continuous data export to connected peripheral devices. The output data structure is described in Appendix 2.
9.2.4 Host Mode
The indicator can communicate with a PC in host mode. You can upload or download data to the indicator by adjusting the related interface parameters within the FLINTEC IndFace software or using the command sets described in Appendix 3. This mode is convenient for process control applications which need not only the weight data, but also require some uploads / downloads and status control.
9.2.5 Print Mode
In the print mode you can select the print formats (parameter group [04-], see chapter 9.2.6). This format
– preferably the single line
– is convenient to use as weight data interface in legal for trade applications which require recording to the Alibi memory. The print mode is not available for more than one interface (see also overview in chapter 9.1).

The Ethernet setup can be done by using the Ether X PC software.
Note: For older instruments the configuration will be done by the Ethernet Device Installer PC software, see separate document on the Flintec Product-CD.
Setup by Ether X Software:
Step 1: Install the Ether X software from the Flintec Product-CD to any PC on the network
Step 2: Start the Ether X software
Step 3:
After pressing the “Search” button the software lists the FT-1x devices on the network as shown in the figure below
Step 4: The IP addr ess of any device may be changed after clicking the “Assign IP” button
Step 5:
Click the “Details“ button to open the parameter window as shown below.
The parameter window presents information like
Firmware Version of Ethernet option board and it helps to edit resources like Host Name, Gateway, DNS server etc.
After changing any parameter, enter the password and click the “Save Settings” button.
The default Password is “123456”.
The “Load Defaults” button resets the device to the default settings.
Frequently Asked Questions (FAQ)
Question: The Ether X could not reach the FT-1x instrument.
Answer:
1. Check the local network connection
2. Check if the IP address of the indicator is convenient for your network
3. Check the PC Ethernet output with other network instruments
4. Check the existence of the Ethernet related parameters in the instrument setup (see chapter 8.3.3). If you cannot not see these parameters in the setup, please check the proper installation of the Ethernet board.
5. Change the Ethernet option board.
FT-12 Technical Manual, Rev. 1.35 November 2010
Page 28 of 44
Question: The Ether X software could reach the FT-
1x instrument, but you can’t communicate with the instrument.
Answer:
The port number of the indicator is not convenient for port numbers of your application software. Check the port number of the indicator by using the Ether X software.
Question: How can I check the communication?
Answer:
You can use any communication program like HyperTerminal which is supplied with your
Windows operating system (Microsoft).
Example: HyperTerminal
1. Open the HyperTerminal and choose a name for the connection.
Press OK.
2. Then enter the Ethernet address of the indicator and the port number as shown at the left. Also you need to set the connection type to “TCP/IP (WinSock)”.
3. To test the connection now, you can set the Ethernet output of the indicator to “continuous” (refer to chapter 8.3.3).
With an active HyperTerminal you should now be able to follow the data stream.

Error Check Calculating:
CSUM = 0
– (Slave_Add + Function + … + Last_data)
(STX and CSUM are neglected while calculating CSUM)
Tool for counting:
0 1 2 3 4 5 6 7 8 9 A B C D E F
Example:
@|01|10|0008|0001|02||0006|DE|<Cr>
To get the check sum (here FA) you have to sum following numbers first:
01+10+00+08+00+01+02+00+06 = 22
Now you have to subtracte 22 from 00:
00 - 22 = DE
(Calculation examples: 00
– 10 = F0 ; 00 – 11 = EF)

NOTE: The points you should paid attention to while loading and reading setpoints are:
To write any value to FT-1x the value should be loaded into the buffer (address 000B). Afterwards send command “6” to address 0008 to make FT-1x to use the value at address 000B.
To read a value from FT-
1x you should send command “7” to address 0008 to make FT-1x to load the value into the buffer. Afterwards you can read the value at address 000B.
The commands “6” and “7” which are sent to address 0008 let you write or read all setpoints

Modbus exception codes
1 : Function code is not supported
2 : Address is out of range (start and end)
3 : Invalid value feed or wrong byte number
4 : Operation error
Explanation (Setpoint, Preset tare):
The reading and writing of the setpoints or the writing of the preset tare is done in two steps.
Read operation (Setpoints):
1. Step : Load the actual setpoint values to the buffer.
Sending the control command 0007 to address [0008] (40 009) stores the actual setpoint values in the buffer address [000B], [000D] and [000F] (Register 40 012, 40 014, 40 016).
2. Step : Read the buffer memory. Reading address [000B], [000D], [000F] (Register 40 012, 40 014, 40 016) replies the actual corresponding setpoint value.
Write Operation:
1. Step : Load the value to the assigned buffer memory. Sending the designated value to address [000B],
[000D] or [000F] (Register 40 012, 40 014 or 40 016) loads the value into the selected buffer memory.
2. Step : Apply the values from the buffer memory. Sending the control command 0006 (setpoints) to address
0008 (Register 40 009) activates the value(s) from the buffer memory.
Attention: Step 2 activates all 3 setpoint buffer values All 3 setpoint values have to be loaded to their buffer memory (step 1) before they can be applied (Step 2).
Terminal [hex] - Examples:
Performing direct read and write operations (Modbus High-
Low) with the instrument address set to “01”. Empty spaces in the example commands are only for a good pattern recognition; Use the commands without spaces.

Data byte count
Data bytes:
Value 1500 in hex
CRC checksum
Calculate check sums:
1. Load a 16
–bit register with FFFF hex (all 1’s). Call this the CRC register.
2. Exclusive OR the first 8
–bit byte of the message with the low–order byte of the 16–bit CRC register, putting the result in the CRC register.
3. Shift the CRC register one bit to the right (toward the LSB), fill a zero into the MSB. Extract and examine the
LSB.
4. (If the LSB was 0): Repeat Step 3 (another shift). (If the LSB was 1): Exclusive OR the CRC register with the polynominal value A001 hex (1010 0000 0000 0001).
5. Repeat Steps 3 and 4 until 8 shifts have been performed. When this is done, a complete 8
–bit byte will have been processed.
6. Repeat Steps 2 through 5 for the next 8
–bit byte of the message. Continue doing this until all bytes have been processed.
7. The final contents of the CRC register is the CRC value.
8. When the CRC is placed into the message, its upper and lower bytes must be swapped as described below.
