2.2 General Safety Information
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, observe the mounting information on
the following pages.
Observe the local installation regulations.
Improper handling of the electronics module can lead to damage to
the sensitive electronics!
Do not work with a blunt tool (screw driver, pliers, etc.) on the
housing!
Use suitable grounding (grounding wrist strap, etc.) when working on
the electronics.
The devices should have a distance of at least 15 mm to one another
in the control cabinet for proper cooling.

3.1 Block Diagram

3.2 System Description
The microprocessor-controlled measuring amplifier EMGZ492.EIP series is used in
processing, amplifying, and relaying sensor signals in suitable form to downstream
devices. The measured force values are available via ETHERNET/IP and an analog
voltage output.
The measuring amplifiers are suitable for tension measurements using all FMS force
sensors. Two force sensors A and B can be connected to the device. Both measuring
values are available as individual signal (A and B), as sum signal (A + B), as differential
signal |A – B| or as average value (A + B)/2 for the master controller.
Furthermore, device information, parameters, and system settings can be accessed via
a web browser. Offset compensation and system calibration can also be performed via
the web browser.

Operating Instructions EMGZ492.EIP
4 Quick Guide/Quick Start
In these operating instructions, commissioning of the EMGZ492.EIP amplifier is limited
to 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:
o Used units in the system
o Used outputs (0 to 10V and bus)
- 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 (see 4.5)
- Connect the amplifier to the supply voltage. The voltage supply must be in the range
of 18 to 36 VDC. (See 4.5)
- Perform offset compensation and calibration (see 5 and Fehler! Verweisquelle
konnte nicht gefunden werden.)
- Change the parameter settings as needed (see 9.2)
- Amplifier integration into the ETHERNET/IP network (see 9.5)
4.3 Mounting 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.
4.4 Force sensor Mounting
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
Two or four force sensors can be connected to the EMGZ492.EIP. When four sensors are
used, two of them have to be connected in parallel. The force sensors and amplifier are
connected using a 2x2x0.25 mm2 [AWG 23] shielded, twisted cable.

The 4 screws of the cover with the PG glands and the M12 plug must be loosened for
board access. You can slide out the board by approx. 2 cm (1 in.) and loosen the
terminal blocks for easier connection of the wires.

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.
Warning
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.

5 Calibration of the Measuring System
There are two options for performing the calibration:
- Via the web browser (see 9)
- Directly in PLC
5.1 Offset Compensation
Using offset calibration, the weight of the measuring roller and the roller bearings 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.
5.2 Calibration (Adjusting the Gain Factor)
Calibration is used for matching the gain factor with the force sensors. After calibration,
the displayed force corresponds to the force effectively affecting the material. Two
calibration methods are available. The first calibration method described here uses a
defined weight. There is also a calculation method for the gain. 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.
If the material tension in the machine cannot be replicated using the weight method
(e.g., for space reasons), the gain can be calculated using the “FMS-Calculator”. This tool
can be downloaded from the FMS homepage.
