4Quick Guide/Quick Start
In these operating instructions, commissioning of the measuring amplifier is limited to
the description of the installation procedure, offset compensation, and system
calibration.
4.1 Preparations for Parameterization
-Read the operating instructions of the selected force sensor carefully.
-Check your requirements on the system, such as:
oUsed units in the system
oUsed outputs (current or power)
-Filter settings for actual force value and analog output
-Create the connection diagram for your specific system layout (see chapter
“Electrical Connection”)
4.2 Mounting Sequence
-Mount the force sensors (mounting details can be obtained from the mounting
instructions of the force sensors)
-Connect the force sensors to the amplifier
-Connect the amplifier to the supply voltage. The voltage supply must be in the range
of 18 to 36 VDC
-Perform offset compensation and calibration
-Change the parameter settings as needed
4.3 Installation and Electrical Connections
Warning
To improve natural convection and keep heating of the amplifiers as
low as possible, the devices installed in a cabinet should have a
minimum distance of 15 mm.
Warning
The function of the measuring amplifier is only ensured with the
components in the specified layout to one another. Otherwise,
severe malfunctions may occur. Thus, the mounting information on
the following pages must be followed
Warning
The local installation regulations ensure the safety of electrical
systems. They are not considered in these operating instructions.
However, they must be met.

Operating Instruction EMGZ310, EMGZ310.ComACT
21.10.2020 9
4.4 Force sensor installation
The force sensors are mounted in line with the mounting instructions of the respective
products. The mounting instructions are included with the force sensors.
4.5 Electrical Connections
One or two force sensors can be connected to the amplifier. When two sensors are used,
they are connected in parallel internally. The force sensors and amplifier are connected
using a 2 x 2 x 0.25 mm2[AWG 23] shielded, twisted cable.

Warning
Poor grounding can result in electric shocks for persons,
malfunctions of the overall system or damage to the measuring
amplifier! Proper grounding must always be ensured.
Note
Cable shielding may only be connected to one side of the measuring
amplifier. On the side of the force sensor, shielding must remain
open.

5Operation and configuration
5.1 Power up the EMGZ 310
-Connect the first force sensor
-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, swap the two
signal wires of this force sensor
-If applicable, connect the second force sensor. Check whether applying a force in
measuring direction on the second sensor results in a positive output signal. If not,
swap the two signal lines of this force sensor.

6Calibration of the Measuring System
6.1 Offset Compensation
Using offset compensation, the weight of the measuring roller is compensated and the
measuring system “zeroed”.
Offset compensation must always be executed prior to the actual calibration. The
measuring roller must not be loaded during the procedure.
-Press and hold the two buttons + (>0< + PARA) at the same time for
longer than 3 seconds. The value for offset compensation is calculated automatically
and stored in the amplifier.
6.2 Calibration (Adjusting the Gain Factor)
Calibration is used for matching the gain factor with the force sensors. After calibration,
the displayed force corresponds the effective material tension of the web / filament.
Two calibration methods are possible. The first calibration method described here uses
a defined weight. There is also a calculation method for the gain factor. The weight-
based calibration method is simple and delivers more accurate results as it replicates
the material profile (see the figure below) and considers the actual circumstances in the
machine.

6.2.1 Calibrating in force mode
Note
If there is no input during 30 sec. while you perform the calibration
procedure, the display will automatically switch back to the initial
screen without saving the previous inputs.
-Insert a rope into the machine. Simulate the exact web path in the machine.
-Load the rope with a defined weight
-Press and hold the two buttons + (CAL + PARA) at the same time for
longer than 3 seconds.
-Enter the system force (Sys_F). The system force is made up of the nominal force of
the connected force sensors. If e.g. two force sensors with a nominal force of 500 N
each are connected, the system force is 2 x 500 N = 1000 N. The nominal force of
FMS force sensors is indicated on the type label.
-You can modify the value with .

7Parameter list
Parameter
Name Description
Output This parameter determines the current output signal of
the amplifier. The voltage output (± 10 V) is also available
in parallel
Selection 0 to 20 mA; 4 to 20 mA
Default 4 to 20 mA
Filter The amplifier provides a low
-
pass filter to prevent noise
overlaying the output signal. The parameter Filter stores
the cut off frequency of the filter. The lower the cut off
frequency, the more sluggish will the output as well as
the display be. The filter stabilizes the output signal in
case of highly fluctuating tension values. A correctly
tuned filter will "straighten" the displayed value.
Unit Hz
Min. 0,1
Max. 999,9
Default 10,0
Unit This parameter determines the unit used in the system.
The label on the force sensor shows always the nominal
force in N.
NOTE: By changing the unit to lb (pounds) the entire
system will change from metric to imperial units.
NOTE: If the system is set to voltage mode [VoltGauge],
this parameter is disabled
Selection N; kN; lb; g; kg
Default N

Operating Instruction EMGZ310, EMGZ310.ComACT
21.10.2020 17
Sys_F The system force indicates which measuring force
capacity is installed in the measuring roller. E.g., if two
500 N force sensors are installed in the roller, 1‘000 N
must be entered. In the case of a one-sided
measurement, hence is one 500 N force sensor is used,
500 N must be entered. If force measuring rollers with
pulleys are used (e.g., RMGZ series), the nominal force of
the force measuring roller must be specified (in the
example 500 N as well)
NOTE: For force values larger than the available 9’999
please change the unit. E.g. for a system force of
12’000N change the unit to kN and enter 12kN as
system force.
NOTE: If the system is set to voltage mode [VoltGauge],
this parameter is disabled
Unit N; kN; lb; g; kg (selected in "unit")
Min. 1
Max. 9999
Default 1000
F@mOut This parameter determines the tension value (N, kN, lb, g,
kg) that is indicated at the maximum output of the
amplifier (10 V or 20mA).
NOTE: If lb (pound) is selected, the system switches from
metric to imperial measuring units.
Selection N; kN; lb; g; kg (selected in "unit"
Min. 1
Max. 100000
Default 1000
Offset The values determined with the “Offset Compensation”
procedure are stored in the form of a digital value in this
parameter. The value is used for compensating for the
roller weight.
Min. -9999
Max. 9999
Default 0
Gain The values determined with the “Calibration” procedure
are stored in the form of a digital value in this parameter.
Min. 0.001
Max. 20.000
Specified value 1.000

Operating Instruction EMGZ310, EMGZ310.ComACT
21.10.2020 18
Mode The Device Mode determines the functionality of the
amplifier. If set to Volt Gauge, force values will be
displayed only in Volt (V) or mA. Force units will not be
available anymore.

8FMS ComACT AppTM
If you have purchased an EMGZ310.ComACT measuring amplifier you are able to
display actual readings and configure the amplifier via the FMS-ComACT 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.
Figure 7: EMGZ310.ComACT with serial number EMGZ310_Typenschild.jpg
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-ComACT 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.
8.1 Configuration via the App
The procedures of offset compensation and calibration are always identical to an
amplifier without Bluetooth connectivity. Instead of using the operating panel of the
amplifier, you can use here any mobile device for input and configuration.
