3.1. Overview

The type FAD-40 A/D Converter Series consists of powerful and economic state-of-the-art instruments for static
and dynamic weighing applications plus force and torque measurements including digital I/O control.
Each instrument of the series converts the analogue low level signal from a load cell or a strain gauge sensor to
a digital high-resolution and high-accuracy signal and transmits the digital data to an external PLC or PC
system. As a special feature the instruments can switch between unipolar and bipolar input range without
affecting the external resolution. Digital I/O ports give further possibilities to extend the bus system with I/O
control in the cabinet and fast response setpoint output from the weighing instrument.
The type FAD-40 A/D Converter Series comprises various instruments for different industrial bus systems:

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-40 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-40 instruments by a Faraday cage or install them in a
separate section or install them far away 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-40 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-40 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 connectors

FAD-40 Technical Manual, Rev.2.0; July 2016 Page 9 of 56

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

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 equipment, 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-40 and the junction box, and short circuit these pins at junction box for better
performance.

Figure 4.2 – Load cell connection

When you use a junction box and one or more load cells with 4 wires you have to short-circuit the excitation
(Exc) and sense wires (Sen) the same polarity as show on the figure 4.21.

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-40 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-40 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 by Key (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-40 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. RS-485 Serial Interface Setup

Data Format

This parameter defines the serial communication port data format for RS-485. The available data formats are:

NOTE: xFace automatically connects to the instrument whatever the data format is. After xFace is
disconnected, the instrument returns to operate with the last saved data format.
WARNING: Disable this interface if it is not used to increase the interfacing performance.
