Warning: Do not forget to connect the Shield pin to the reference ground.

PRECAUTION: Please read this manual carefully before you install the instrument. If you apply all

recommendations in this chapter you will increase the reliability and long term performance of your system.

4.1. Recommendations

4.1.1. Control Cabinet Design

Warning: Please follow the following warnings for designing the control cabinet which will increase the

reliability of your system.
The control cabinet should be designed therefor the A/D converters can operate safely. The panel should be
placed in a clean area, without getting direct sun light if possible, with a temperature between -10 ºC and +40
ºC, humidity not exceeding 85% non-condensing. All external cables should be installed safely to avoid
mechanical damages.
FAD-30 instruments are very low level signal measuring instruments. To avoid electrical noise, the instruments
should be separated from equipment that produces electrical noise. Preferably use a metal cabinet against
radio frequency interference, to protect against electromagnetic disturbance the cabinet shall be connected to
ground. Keep the load cell cable trays separated from others, if possible. If there is noise-generating equipment
such as heavy load switches, motor control equipment, inductive loads etc., please be careful against the EMC
interference in the cabinet. If possible protect FAD-30 instruments by a Faraday cage or install them in a
separate section or install them far a way from this kind of equipment. Install parallel reverse diodes to the DC
inductive loads like relays, solenoids etc. to minimize voltage peaks on the DC power lines.

4.1.2. Cabling

All cables coming to the control cabinet shall be shielded. Please use separate cable trays for these low signal
level cables. Distance from load cell cables, interface cables and DC power supply cables to power line cables
shall be 50 cm at minimum.

4.1.3. Mechanical Installation

After designing the control panel and installing DIN rails according to the recommendation in this chapter, place
the FAD-30 instruments on the DIN rail Be sure that the mechanical installation of the instruments is done
properly.

4.2. Electrical Connections

Warning: Please always remember that FAD-30 instruments are very low voltage measuring instruments. Your

control cabinet design and proper installation increases the reliability and the performance of the instrument.
Please do not forget that the instrument must be powered off before inserting or removing any peripheral
connector. All required electrical connections should be done as described below.

4.2.1. Power Supply and Grounding

The power supply voltage of the instrument shall be between 12 V DC and 28 V DC. The current consumption
of the power supply will be calculated by multiplying 0.2 A and the quantity of instruments. The pin configuration
of the 24 V DC power supply connector located at the bottom front of the instrument is shown below in figure

4.1.

Figure 4.1 – The pin layout of 24 V DC connector

FAD-30 Technical Manual, Rev. 1.06 December 2012 Page 10 of 48

The quality of the instrument‟s ground will determine the accuracy and the safety of your measuring system. A

Load Cell
Connector

4 wire LC connection

6 wire LC connection

Warning: Connect the load cell cable shield to the reference ground or the

shield pin of the load cell connector.

Please refer to the corresponding chapter:

FAD-30 (RS485)

see chapter 6.2

FAD-30MB (Modbus RTU)

see chapter 6.2

FAD-30PB (Profibus)

see chapter 7.2

FAD-30PN (ProfiNet)

see chapter 8.2

FAD-30EN (Ethernet and Modbus TCP)

see chapter 9.2

FAD-30CO (CANopen)

see chapter 10.2

proper ground connection is needed to minimize extraneous electrical noise effects on the measurement. A
poor ground can result in an unsafe and unstable operation. It is important that the instrument should 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 poor, prepare a special power line and
grounding. Before interfering the instrument, turn off the power and wait at least for 30 seconds.

4.2.2. Load Cell Connection

To avoid damages, the load cell wiring should be made carefully before energizing the instrument. Load cell
connection details are shown below in figure 4.2. In 4-wire installations the sense and excitation pins with the
same polarity should be short circuited at the connector side. If you have a junction box in your system, use a 6
wire cable between FAD-30 and the junction box, and short circuit these pins at junction box for better
performance.

4.2.3. Communication Interface

4.3. Commissioning

PRECAUTION: Please read this manual carefully before energizing the instrument. Perform the commissioning

operation according the procedure given in this chapter. Only trained persons are allowed for cleaning,
commissioning, checking and servicing of the instrument. The interference of untrained person may cause
some unwanted damages or injuries.
Before energizing the instrument, please make the required mechanical and electrical installations. After power
on, you have to setup your FAD-30 instrument before you can start to use the bus interface.
Install the xFace software onto your PC as described in chapter 5 Setup. The xFace software is used for setup,
calibration and testing of FAD-30xx instruments.

WARNING: Read this manual carefully before you setup and calibrate the instrument. This will increase the
performance of your weighing system by applying proper setup and calibration.

Figure 5.3 – FAD-30 Setup Parameters

For entering the parameter values enter the setup tab, adjust the parameter settings and then write this data to
the A/D Converter. After changing parameter settings the instrument always requires a re-calibration.

5.3.1. Scale Parameters

In the setup menu the scale parameters of FAD-30 can be viewed, changed or saved to the instrument. These
parameter settings are:

Increased External Resolution

For service purposes this parameter enables the 10 times higher resolution of the weight value than the defined
interval in weighing and force mode. Increased resolution must be disabled for use in normal operation (Not
available in Count Mode). Default setting: „Disable‟.

Digital Filter

Environmental noise like bounding forces, air flow, vibration, motor control instruments etc. may disturb the load
cell signal. The selection of proper filter settings determines how quickly the system will react to the load cell
signal.**Load cell signal digital filtering is done according to this parameter settings. The settings can be
changed from 0 (fastest settling) to 9 (slowest settling). Default setting: „7‟.

This parameter defines the motion detection window which determines a stable weighing. If motion detection is
not required, this parameter can be disabled. The available motion detection window values are:

Weighing and Force Mode:

Count Mode:

Power On Zero

This parameter enables automatic zeroing after powering on the instrument. The automatic zeroing is only
done if the total zero drift from the calibrated zero signal is in the defined zeroing window. This zeroing window
will be defined in the percentage of the scale capacity.

To avoid unwanted zeroing at power on this parameter should be disabled or carefully set up in applications
like silo weighing, tank weighing and automatic weighing applications. If the weight is not within the power on
zeroing range, the instrument is powered on without zeroing (Not available in Count Mode).

Zeroing Range

Zeroing of the scale is performed if the difference between load cell signal value and unloaded load cell signal
value at the calibration is in the selected percentage of the scale capacity. Zeroing can be done by zeroing
command when the scale is stable. Zeroing can be done by zeroing command when the scale is stable.
The available zeroing ranges in the percentage of the scale capacity are:

Auto Zero Tracking

AZT automatically re-adjusts the scale to zero for compensating defined small deviations around the center of
zero. AZT only works within the defined zeroing range and stops working if this range is left.To avoid unwanted
zeroing this parameter should be disabled or carefully set up in applications like silo weighing, tank weighing
and automatic weighing applications (Not available in Count Mode). The available AZT window values are;

Tare

If this function is enabled, the weight is tared when the tare command is received. Additional conditions for
taring are positive gross weight and no motion. Multi-taring is possible with FAD-30 series (Not available in
Count Mode). Default setting: „Enable‟.

Save Tare at Power Off

If this function is enabled, the tare value is stored at power off and the instrument starts up in Net mode at
power on (Not available in Count Mode). Default setting: „Enable‟.

5.3.2. Serial Interface Setup

Data Format

This parameter defines the serial communication port data format for RS232 respective RS485. The available
data formats are:

Figure 5.5 – Calibration by test weights

FAD-30 instruments have three operation modes which are:

Select the scale operation mode and the polarity. Then click the “Write to A/D Converter” button to save your

mode selection. The default calibration of FAD-30 instruments is Count Mode and 10 mV unipolar input signal
range. If you select the Count Mode, there is no scale build and instrument calibration. Each FAD-30 instrument
is adjusted for high accuracy during the production. The FAD-30 input signal ranges and their external
resolutions are shown in Table 5.1.

Table 5.1 - Count Mode, Input Signal Ranges and External Resolution

Select the input signal level and polarity for high external resolution. Write your mode selection to the
instrument by clicking “Write to A/D Converter” button. Jump to the chapter 5.4.

Scale Build

The scale capacity, the increment and the unit have to be introduced to the FAD-30 instrument before you can
perform a calibration in Weighing or Force mode.

The scale calibration can be performed by using test weights or by electronic calibration (eCal).

Calibration by Test Weights

This calibration method performs zero and span calibrations using test weights. For accurate calibration the test
weight value should not be less than 1/10 of the scale capacity.

Please note that the scale build values should be entered before you start the calibration.

Select “Full Calibration” for performing a complete scale calibration. Click the “Start” button. Unload the scale
for performing the zero calibration and click the “Yes” button. The virtual display will show the [WAIT] message

during the zero calibration. During the zero calibration the scale must be stable. Approximately 5 seconds later
the span calibration window will be displayed. Load the scale and enter the loaded test weight value, then click

the “OK” button. The scale must be stable during the span calibration. Approximately 5 seconds later the new

calibration settings are saved automatically.

If any error occurs during the calibration an error message warns you. Click the “Yes” button to reload the
previous values or click the “No” button to use the new settings.
You can adjust the zero or the span of your scale without performing a full calibration. Additionally the “span
calibration to the unloaded scale” feature is another tool of FAD-30 instruments for after-sale services.

FAD-30 Technical Manual, Rev. 1.06 December 2012 Page 16 of 48

Zero Adjustment

Figure 5.6 – eCal Calibration

If your scale has a residual zero drift you may perform a zero adjustment only. Select “Zero Adjustment” and
press the “Start” button. Then the zero calibration window will be displayed. Unload the scale and click the “OK”

button. The [WAIT] message appears on the virtual display during the zero adjustment. Approximately 5
seconds later the zero adjustment will be finalized.
Note: Zero adjustment is also performed over the bus interface. Refer to the data structure of the related bus
interface.

Span Adjustment

If your scale has a span drift, you may perform a span adjustment only. After selecting “Span Adjustment” and
pressing the “Start” button, enter the test weight value; place the test weights on the scale and press the “Yes”

button. The [WAIT] message appears on the virtual display approximately for 5 seconds while the span
calibration is being performed. After finalizing the span adjustment, the instrument will save the span
coefficients automatically.
Note: Span adjustment is also performed over the bus interface. Refer to data structure of the related bus
interface.

Span Adjustment under Load

This feature is being used to perform a span adjustment without unloading the scale. This operation is
especially used for the span adjustment for non-empty tanks to make a span adjustment without emptying the
tank. After selecting “Span Adjustment under Load” press the “Start” button. The temporary zeroing message
appears on the monitor. This means the instrument will determine the existing load as the temporary zero. If the
scale is stable press the “Yes” button. The [WAIT] message appears on the virtual display approximately for 5
seconds to determine the temporary zero. Then the span calibration window will be displayed. Load the scale
and enter the loaded test weight value, then click the “OK” button. The scale must be stable in this period.
Approximately 5 seconds later, the new calibration settings are saved automatically.
Please refer to the chapter 5.4 A/D Converter Performance Test).

Electronic Calibration (eCal)

eCal allows to perform a calibration without using test weights. FAD-30 is adjusted during production for
increased eCal accuracy. The calibration will be done based on the scale capacity, the total load cell capacity,
the load cell output and the estimated dead load. If the conditions are convenient for zero calibration, you may
perform automatic zero adjustment instead of entering an estimated dead load.

After selecting eCal calibration enter the following values as:
Total Load Cell Capacity: Enter the total load cell capacity in kg as shown in the example below.

Example: If the weighing system has 4 pcs 1000 kg load cells, then enter 4000 kg.
Average Load Cell Output: Enter the load cell output in mV/V. If the weighing system has more than one load

cell, calculate the mean value of the load cells output as indicated in the certificates of the individual load cells.
Example: If the load cell outputs are LC1: 2.0010, LC2: 1.9998, LC3:1.9986 and LC4:2.0002, the mean value

will be LC output = ( 2.0010 + 1.9998 + 1.9986 + 2.0002 ) ÷ 4 = 1.9999 mV/V.
Estimated Dead Load: Enter the estimated dead load value of the weighing system in kg. You may perform a

zero adjustment in convenient time for an exact dead load compensation.
After pressing “Save eCal Data to Converter” these data will be transferred to the instrument and eCal will be
finalized.
If the scale is empty and you want to make an automatic zero adjustment instead of entering an estimated dead
load, then press the “eCal with Zero Adjustment” button for starting the zero calibration. The display will show
the [WAIT] message during the zero adjustment for approximately 5 seconds. In this period the scale must be
unloaded and stable. The eCal calibration coefficients are saved automatically.

The scale performance test should be performed before you install the bus connection. The tests are linearity,
repeatability and eccentricity. You can follow the test at the virtual display and/or status tab which show the
measurement data, the instrument data and the software version. For convenience keys for Taring, Zeroing
and Clear are located in this tab.

5.5. Bus Interface Setup

FAD-30 instruments have a bus interface and these parameters have to be setup before the bus will be
connected. Bus communication settings are done in the Gateway tab.
Bus communication parameters and their descriptions can be found in the related instrument chapters.

5.6. Bus Addressing via Setup Switch

The bus addressing of FAD-30 instruments is done by the xFace software (Refer to chapter 5.3.1). The
alternative way for addressing is the setup switch on the front panel for addresses between 0 and 7 for RS-485,
Modbus RTU, Profibus and CANopen interfaces. This feature gives you the practical advantage for addressing
the instrument up to address 7 without requiring a PC connection.
For addressing via the setup switch, press this switch for 5 seconds. Then the status LEDs indicate the bus
address as shown in the table below. If the address is higher then 7 all LEDs are flashing. The address can be
changed by pressing the setup switch sequentially. To save and exit, press the setup switch for 5 seconds. To
return to normal operation without saving, wait 15 seconds without pressing the switch.

5.7. Back up Settings and Calibration Data

The parameter settings and the calibration coefficients can be saved to a backup file after reading these data
from the FAD-30 instrument. This backup file can be re-written to FAD-30 after opening it by xFace.
The backup feature gives a service advantage to FAD-30 instruments. We propose to burn these files to CD /
DVD and save this backup CD / DVD in the control cabinet additionally to a backup file on your PC.

Important note: The previous parameter settings and calibration coefficients in FAD-30 will get lost after
loading a backup to the instrument.

INTERFACE

FAD-30 and FAD-30MB instruments are state-of-the-art strain gauge load cell signal digitizers with RS-485
interface. These instruments are used for any type of process weighing and force measurement including tank
and silo weighing, dynamic weighing, check weighing, filling, tension /compression force measurement etc.

6.1. Front View

There are 3 status LEDs on the front panel which indicate the operational instrument status (Refer to table 6.1).
The setup switch on front panel of the instrument is used for RS-485 addressing without PC (Refer to chapter

5.6) and for diagnostics (Refer to chapter 12).
When the error LED is ON, the other two LED indicate the error type (Refer to chapter 11 for details).
Load cell connection, power supply and serial interface terminals are located at the front of the DIN rail mount
instrument (See figure 6.1).
