1 Safety Instructions
1.1 Description conditions
a) High danger of health injury or loss of life
Danger
This symbol refers to high risk for persons to get health injury or loss of life. It has
to be followed strictly.
b) Risk of damage of machines
Caution
This symbol refers to informations, that, if ignored, could cause heavy mecanical
damage. This warning has to be followed absolutely.
c) Note for proper function
Note
This symbol refers to an important information about proper use. If not followed,
malfunction can be the result.
1.2 List of safety instructions
Proper function of the Tension Measuring Amplifier is only guaranteed with the
recommended application of the components. In case of other arrangement,
heavy malfunction can be the result. Therefore, the installation instructions on the
following pages must be followed strictly.
Local installation regulations are to preserve safety of electric equipment. They
are not taken into consideration by this operating manual. However, they have to
be followed strictly.
Bad earth connection may cause electric shock to persons, malfunction of the
total system or damage of the electronic unit! It is vital to ensure that proper
earth connection is done.
Improper handling of the electronic boards may cause damage to the fragile
equipment! Don’t use rough tools such as screwdrivers or pliers! Operators
handling the electronic boards must wear a well earthed bracelet in order to
discharge static electricity.
2 Product Description
2.1 Product Range
The tension measuring amplifier series EMGZ309 is available in two versions:

Operation Manual EMGZ 309.EIP
20.12.2018 5
• EMGZ309._ with standard analogue outputs
• EMGZ309._.EIP with analogue outputs and integrated EtherNet/IP interface
Both versions are available in three different housing / mounting options:
• EMGZ309.R rail mount housing
• EMGZ309.S panel mount housing
• EMGZ309.W wall mount housing
For mechanical dimensions refer to charter 10.

2.3 System Description EMGZ309
The digital tension measuring amplifiers EMGZ309 are suitable for tension
measurement with all FMS force sensors. The amplifier can handle 1 or 2 force
sensors. Three different analogue output modes can be selected (0…20mA,
4…20mA or 0…10 VDC). As a plug & play unit the setup through the operating
panel is straightforward and quickly accomplished. Alternatively, more advanced
users can access all the internal parameters through a laptop or local PC via a web
browser. That allows a fine tuning of the amplifier even to the most demanding
system requirements.

2.4 System Description EMGZ309._.EIP
The amplifier EMGZ321._.EIP offers in addition to his standard features the
possibility to be used as an EtherNet/IP device in a corresponding network.
EtherNet/IP bases on the Ethernet TCP/IP and the UDP technology as well as on
the CIP (Common Industrial Protocol). The amplifier can be embedded in a
standard Ethernet infrastructure. The EMGZ309.EIP offers a EtherNET/IP data
transfer rate with ≥2ms. It allows the measurement of web tension and its
transmission over Ethernet to a controller in real time. Configuration of the
amplifier takes place either over the EtherNet/IP, a web browser or over the
operating panel.

3 Quick Installation Guide
In a Plug & Play configuration the set-up of the EMGZ309 and force sensor is limited
to only the offset compensation and the calibration.
3.1 Preparations for Set-up
1. Read the Operation Manual of your force measuring sensors
2. Check your requirements such as:
– Display unit of nominal force
– additional output configuration 0…10V or 0/4… 20mA on display
3. Draw the wiring diagram for your configuration (ref. to 3.5 “Wiring the Amplifier“)
4. If required, determine special parameters (ref. to 8.2 “Parameter List”)
3.2 Installation Procedure
1. Mount your force maesuring sensors to the machine frame
2. Wire the Force Measuring Sensor(s) (ref. to Fig. 4)
3. Connect the amplifier to the power supply. The power supply voltage must be in
the range 18 to 36V DC.
4. Perform offset compensation and calibration (ref. to chapter 4.5 to 4.9)
5. If required, do additional settings (ref. to 8“ Parameterization over Operating
Panel”)
6. Integration of amplifier in an Ethernet network and PLC (see chapters 5.3 and 6)
3.3 Installation and Wiring
Caution
In order to improve the natural convection and keep the temperature of the
amplifiers that are mounted in a cabinet, to a minimum, a distance of at least
15mm (0.6”) between the devices must be kept.

Caution
Proper function of the Tension Measuring Amplifier is only guaranteed with the
recommended application of the components. In case of other arrangement, heavy
malfunction can be the result. Therefore, the installation instructions on the
following pages must be followed strictly.
Caution
Local installation regulations are to preserve safety of electric equipment. They are
not taken into consideration by this operating manual. However, they have to be
followed strictly.
3.4 Mounting the Force Sensors
Mounting of the force sensors is done according to the FMS Installation manual
which is delivered together with the force sensors.
3.5 Wiring the Amplifier
One or two force sensors can be connected to the measuring amplifier. When
using two force sensors, the sensors are internally connected in parallel. The
output signal of the measuring amplifier will then correspond to the average value
of the two sensors. The connection between force sensors and measuring
amplifier has to be done using a 2x2x0.25mm2[AWG 23] shielded twisted-pair
cable

Ethernet connectors EMGZ_309_BA_Manual.ai
Caution
Bad earth ground connection may cause electric shock to persons, malfunction of
the total system or damage of the electronic unit! It is vital to ensure that proper
earth connection is done. The cable must be installed separate from power lines
Note
The shield should be connected only to the electronic unit. On the force sensor side
the shield should stay open.

4 Configuring the Amplifier
The amplifier EMGZ309._.EIP can be configured over the operation panel (chapter
8), over a PC (web interface, chapter 9) or over EtherNet/IP. The basic
configuration is performed over the operation panel.
4.1 Power up the EMGZ 309._.EIP
1. Connect the first force sensor (see Fig. 4 Wiring Diagram EMGZ309)
2. Check whether applying a force in measuring direction (in the direction of the red
point) on the first sensor results in a positive output signal. If not, exchange the
two signal wires of the corresponding force sensor (terminals 12/13).
3. If applicable, connect the second force sensor.
4. Check whether applying a force in measuring direction on the second sensor
results in a positive output signal. If not, exchange the two signal wires of the
corresponding force sensor in the terminal block (terminals 22/23)
