4.Installation and Commissioning

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“.

4.1Mechanical 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 3.4. 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)

J2 Calibration

(short circuit for calibration)

Only for FT-11(D) & FT-12

J17 short circuit for on/off key function

Figure 4.1 FT-11(D) Main board

4.2.Electrical Connections

4.2.1.Power Supply and Grounding

FT-11(D) is available with 230 V AC power supply or 24 V DC or 12 V DC power inlet. The 230 V AC indicators are supplied with a power cable; the DC indicators are supplied with a special connector for the power inlet. Prepare your power voltage according to your instrument’s power inlet. The DC connector pin configuration can be found in Figure 4.2 below.

	Definition	Pin no.	Pin no.
		for desk and panel type	for stainless steel housing
	12 V / 24 V	1	3
	0 V	2	2
	Housing Gnd	3	1

Desk / Panel	Figure 4.2 The pin layout of the DC 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-11(D) Technical Manual, Rev. 1.35 November 2010

Page 10 of 52

4.2.2.Standard Load Cell Connection (for FT-11 only)

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.

	COM B	7	3
	Shielding	Connector body	4

4.3.Commissioning

After making the required installations and connections to your indicator, turn the power on and perform following steps:

Get familiar with the instrument’s setup mode (see chapter 6.1)For FT-11D only: Define the digital load cells (see chapter 6.2)Define the configuration parameters (see chapter 6.3)*

Define the scale parameters (see chapter 6.4)Calibrate the scale (see chapter 6.5)

* Note: Most of the parameters can be skipped for later setup. Please take care for the parameters which may be locked by the J2 calibration jumper in legal for trade applications (see Appendix 1: Setup and Calibration Menu of the instrument).

If you want to use the Flintec IndFace Software (for FT-11 only) then you have to set up the instrument’s standard serial interface to host mode (see chapter 9.2) before you adjust all the configuration parameters.

After checking the performance of your weighing instrument you can begin to use the indicator.

If there are peripheral connections, first you should turn the power off; make the peripheral connections, perform the required safety checks and energize the indicator. Then set the related parameters and check if the peripheral devices are operating properly.

If required perform following additional steps:

Set up the serial interfaces (see chapter 8.2)Printer setup (see chapter 8.2)

Set up other optional inputs and outputs (see chapter 8.3ff and 9)

The calibration jumper (see chapter 4.1) should be short circuit to change the legal metrological parameters in the service mode (there is black box on the top right corner of the grey coloured boxes in the calibration menu flowcharts, see Appendix 1).

The Setup and Calibration menu consists of main blocks which are displayed as [X-- ] and sub-blocks.

By using < > and < > keys you can reach previous or next main blocks. After reaching the desired main block you can get in by pressing the <Enter> key. As you enter the block you will reach the first sub-block in that main block. The sub-block address will be seen on the display as [X0- ].

You can also search between the sub-blocks by using < > and < > keys and reach the first parameter of the displayed sub-block by pressing the <Enter> key. The number of the parameter is displayed as [XY0 ]. Again

you can search between parameters by < > and < > keys.

For entering numerical values in the parameters press the <Tare> key to select the digit and press the <Zero> key to change the value.

6.1.3.Exiting the Setup and Calibration Menu

Whatever parameter block you are in – if you press the <F> key, you will get out of the active sub-block and reach the next sub-block. If you press the <F> key again you will get out of the active block and reach the next main block. If you press the <F> key once again, the [SAvE ] message appears on the display.

Here you can press

the <Enter> key to save the changes into the memory or

you can press the <Tare> key to store the changes temporarily until the power goes off oryou can press the <F> key to abort any changes.

The [Waıt] message will be displayed for a few seconds and afterwards the weighing mode will restart automatically. Especially for legal metrological usage, please don’t forget to turn the power off and remove the calibration jumper before you start the operation.

6.2.Defining the Digital Load cells (for FT-11D only)

6.2.1.Digital Load Cell Addressing

The parameter group [22-] is used for defining and addressing the DLCs.

[22-] DLC Configuration Block

In this section the DLCs are introduced to the indicator.

[220 X] DLC Type

0 = RC3D

This parameter must be set to “0” for type RC3D digital load cell.

[221 XX] Quantity of DLC

Enter the quantity of DLCs used in the scale. The quantity can be selected between 1 and 16.

[222 ] DLC Addressing

The following diagram shows the addressing principles of the DLCs in a weighbridge / truck scale. The numbers in the diagram show the DLC addressing principle for easy eccentricity adjustment.

					1	3	5	7	9
	Entrance										Exit
					2	4	6	8	10
		Figure 6.1				The addressing principles of the DLC’s in a weighbridge / truck scale
For addressing of DLCs, press the <Tare> key.
The messages			[222 YY] and [ XXXXXX ] will be displayed alternately.
Here:			“YY”			DLC number /address
			“X”			Last 6 digits of the DLC’s serial number

If you press <Enter> the next load cell will be shown, the <F> key is used to return the parameter group [20-].

You can enter the S/N, by pressing the <Tare> key. The serial numbering system of the indicator is 9 digits. First you will see the first 3 digits of the S/N. Enter this digits by pressing the <Tare> and <Zero> keys. If the serial number of the DLC is less than 9 digits, the unused digits on the left must be set to “0”. For example, if the serial number is “1234567” then “001234567” must be entered. After entering the first 3 digits, the following 6 digits are entered by pressing <Enter>.

Important hint: When addressing the connected Type RC3D load cells, the load cells should always be loaded. If the load cells are unloaded, FT-11D may show a DLC input error.

After entering all serial numbers sequentialy, the display goes to parameter group [20-]. This means all load cells are addressed and ready to work in the scale.

For replacing any load cell, you have to re-address the new load cell in parameter [222]. After installing the new load cell, turn on the indicator. Enter parameter [222] and then access the load cell address of the replaced DLC. Enter the serial number of the new load cell as described in the previous paragraph.

Note: It is always assumed that the RS485 load cell bus system is correctly terminated, please see the manual of the installed junction box.

6.2.2.Eccentricity Adjustment

The eccentricity adjustment must be done in parameter group [32-] before the calibration of the scale. The adjustment can be done for each load cell independently or for sectional pairs. The selection is done by parameter [320]. After selection of the adjustment method , the adjustment is performed automatically as described in parameter [321].

[32-] DLC Eccentricity Adjustment Block

In this parameter group the eccentricity correction is performed automatically or manually. This adjustment must be performed automatically before calibration.

[320 X] Adjustment Method

The scale eccentricity can be adjusted in corners (each DLC individually) or in sectional pairs. 0 = Independent DLC (factory default) 1 = Sectional pair

[321 ] Auto Adjustment

After entering parameter [321] by pressing the <Tare> key, you will see [Zero CA] on the display. Unload the scale and press the <Enter> key. Do not interfere the scale during the period the [Waıt] message is displayed. Next the instrument will display [321 01]. Place a weight of at least 10% of the DLC capacity as close as possible to the independent load cell or sectional pair 1. Then press <Enter>. After some period [321 02] appears on the display. Apply the same load to the other places in sequence.

After loading all load cells / sections the message [322 ] will be shown on the display. This means the eccentricity error correction is performed automatically.

[322 ] Manual Adjustment

If needed the eccentricity error can get modified manually. You can change the error correction coefficients of the DLCs in this parameter. For entering this parameter press the <Tare> key. You can change the load cell number by the <Enter> key. For changing the coefficient of any DLC select the number of the DLC and press the <Tare> key to view and edit the coefficient. Use <Tare> and <Zero> keys for changing the value and then press the <Enter> key.

To exit this parameter press the <F> key and save the changes you applied by pressing <Enter>. The <F> key is used to quit without saving the manual corrections.

[323 X] Service mode: Set Shift Coefficients manually to 1

This parameter allows you to view the weighbridge’s performance with disabled eccentricity correction for service purposes. Using this function does not change any stored coefficient but all coefficients are “temporarily” set to value 1.

0 = Normal operation (factory default)

1 = Service mode

Attention: After the eccentricity adjustment a scale calibration has to be done.
