2 Quick Installation Guide
In a Plug & Play configuration the set-up of the EMGZ310 and force sensor is limited to
only the offset compensation and the calibration.
2.1 Preparations for Set-up
1. Read the Operation Manual of your force measuring sensors
2. Check your requirements such as:
− Desired output configuration ±10V or 0/4… 20mA
− Devise Mode (Force Gauge or Volt Gauge)
− Cut off frequency of low-pass filter
3. Draw the wiring diagram for your configuration (ref. to 2.6 “Wiring the
Amplifier“)
2.2 Installation Procedure
1. Mount your force maesuring sensors to the machine
2. Wire the Force Measuring Sensor(s) (ref. to Fig. 1 and 2)
3. Connect the amplifier to the power supply.
4. The power supply voltage must be in the range 18 to 36V DC.
5. Perform offset compensation and calibration (ref. to chapters 3.4 to 3.7)
6. If required, do additional settings (ref. to 4 “ Parameterization”)
2.3 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.
2.4 Installation and wiring
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.

Fig. 1: Block diagram EMGZ 310 E310001e
2.6 Wiring the Amplifier
One or two force sensors can be connected to the measuring amplifier. When
using two force sensors, 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.
Fig. 2: Wiring of EMGZ 310 E310002e
Operating Manual EMGZ 310
10.01.2017 9
Caution
Bad earth connection may cause electric shock to persons, malfunction of the
total system or damage of the control unit. It is vital to ensure a proper earth
ground connection.
Note
The shield should be connected only to the electronic unit. On the force sensor
side the shield should stay open.
Note
Sensor cables must be installed separate from power lines.
2.7 Modify the wiring
For an easy and quick exchange of an amplifier it is possible to exchenge the
single terminal blocks as assembly. You neither have to disconnect the wiring,
nore do you have to open the housing of the device.
Make sure that the amplifier is disconnected from the power supply.
Insert a screw driver with a small blade in
between the terminal block and the housing on
the top end of the block
Using the screw driver as a lever will loosen the
block from the housing. It will slide downwards
The block is now disconnected. You can slide it
out the device.
Insert the block on the desired position. Push
the block fully into the slot. You will hear a
“click” sound as the block interlocks

3 Configuring the Amplifier
3.1 Power up the EMGZ 310
1. Connect the first force sensor (see Fig.2 Wiring Diagram EMGZ310)
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 this force sensor in the terminal block (terminals 6/7).
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 this
force sensor in the terminal block (terminals 6/7).
3.2 Operating the EMGZ310 over the Operating Panel
The EMGZ310 amplifier can go in 4 different states:
Operation State: Amplifier operating
Offset Compensation: Automatic procedure to offset the roller weight
Calibration State: Procedure to calculate the amplifier gain
Parameterisation State: Set or change parameters
When using the operating panel, the user can toggle between these modes by
pressing a key or a combination of keys.
3.3 Operating Panel
The keys on the operation panel have the following functions:

3.4 Change the Device Mode
The EMGZ310 amplifier has two Device Modes:
● Display of Force Gauge: Tension data are displayed in a force unit
● Display of Voltage Gauge: Tension data are displayed in Volt (V)
1. Press the PARA key for longer than 3 seconds, to enter the
parameter-selection mode. The display changes to
2. Scroll down the parameter list with the keys until you see on the LCD
3. Press the key to enter the Parameter Chang Mode
4. Select V for Voltage Gauge or kgkNN for Force Gauge
5. Confirm the parameter change with the key
6. Leave the Parametrisation by holding the key for longer than 3 sec.
Caution
Each change of the Device Mode requires a re-calibration of the system
3.5 Offset Compensation
With the Offset Compensation the roller weight is compensated. It is always
performed before the calibration. The Force Measuring Sensor should not be
loaded while the Offset Compensation is performed.
1. Start offset compensation by pressing the two keys >0< + PARA at
the same time for longer than 3 seconds.
2. The offset compensation is done automatically.(see state diagram Fig.4)

3.6 Calibration
By calibrating (setting the Gain), amplifier
and force sensors are adjust so that the
display gives the actual tension value. There
are two methods of calibrating the system.
The first method uses a defined weight
attached at a rope (see Fig. 5). The second
method is based on a calculation process in
conjunction with the FMS Calculator tool. The
method with the calibration weight is
preferred since it simulates the real material
path in the machine and delivers the most
accurate results.
If the material tension cannot be simulated
in the machine by the weight method (e.g.
because of space restrictions), the gain can
be calculated with the FMS Calculator tool.
This Calculator can be down loaded from the FMS web page.

3.7 Calibration Procedure in the Force Gauge Mode
Note
If you do not press any key on the operating panel the display will automatically
switch to the intitial screen. You have to repeat any previously performed steps.
Execute the single steps uninterrupted and prepare any required material in advance.
1. Load a rope with a defined weight corresponding to your calibration force on the
roller. The roller configuration must correspond to the real configuration in the
machine (wrap angle, distance of the rollers etc.).
2. Enter calibration mode by pressing the two keys Cal and PARA at
the same time for longer than 3 seconds. The display changes to
3. The System Force [Sys_F] determines the measuring capability of your measuring
roller. E.g. if two 500 N sensors are installed, enter 1000N. If only one 500N
sensor is used, enter 500N (see chapter 4.3 “Descriptions of Parameter”, [Sys_F]).
4. Use the keys to enter the system force. The LCD shows:
5. Press the key to confirm your input.

7. Press the key to confirm your input. The display changes t
8. The parameter [F@mOut] determines the force corresponding to the
maximum amplifier output (10V or 20mA) (see chapter 4.3)
9. Enter the value of [F@mOut] with the keys and confirm your
input with the key. The calibration procedure has been completed successfully.

5 Configuration via FMS ComACTTM app
If you have purchased an EMGZ310.ComACT measuring amplifier you are able to
display actual readings and configure the amplifier via the FMS ComACTTM app.
You can identify the type of amp on the type label. The EMGZ310.ComACT has
also the last 4 digits of its serial number printed on the front housing.
Only a single mobile device at a time can connect to an amplifier.
As soon as the connection between amp and mobile device is setup, the display of
the amp will start flashing.
The FMS ComACTTM app is meant as an operation aid to display actual readings
and to help configure the amplifier. The settings are only stored in the amplifier
and not in the mobile device.
