Page 4: Safety Instructions
Operation Manual EMGZ490A 1 Safety Instructions All safety related regulations, local codes and instructions that appear in the manual or on equipment must be observed to ensure personal safety and to prevent damage to the equipment connected to it. If equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired. -
Page 5: List Of Safety Instructions
There is the possibility of a system overload, if such a service is nonetheless used. The consequence is a connection interruption between EMGZ490A and PLC. The interruption usually lasts between 3-5 seconds. Afterwards, a new connection is automatically established again. -
Page 6: Product Description
The measured force values are accessible via the PROFINET bus and on an analog voltage output. The amplifiers are suitable for tension measurement with all FMS force sensors. Either one or two sensors can be connected to one amplifier. -
Page 7: Quick Installation Guide
Operation Manual EMGZ490A 3 Quick Installation Guide The set-up of the EMGZ490A and force sensors is limited to only the installation procedure, offset compensation and the calibration. 3.1 Preparations for Set-up 1. Read the Operation Manual of your force measuring sensors 2. -

Page 10: Calibration Of The Measuring System
The second method is based on a calculation method in conjunction with the FMS Calculator. This Calculator can be down loaded from the FMS web page. FMS recommends using the method with the weight (see Fig. 3) since it delivers the most accurate results. -
Page 11: Calibration Procedure
Operation Manual EMGZ490A 4.3 Calibration Procedure 1. Activate web interface (ref. to chapter 8.1) and call web page „Offset/Calibration over the web browser” (see chapter 8.3). 2. Connect volt meter to the voltage output (Fig. 2, terminal 13/14) 3. Connect first force sensor to the amplifier (see Fig. 2). -
Page 12: Gain
It replaces the binary value (first digit). This calculation method is also used by the FMS Calculator tool. Thus it is possible to use the gain value calculated by the FMS Calculator directly in the calibration. The gain value is then In this entered in the parameter set of the amplifier (see chapter 8.2 “Parameter Setting”). -
Page 13: Limit Violations
Test Rules: The FMS force sensors deliver at the rated nominal force at the output 9mV. The maximum load at the mechanical hard stop is 12.4mV. The amplifier checks the overload in the positive measuring direction (red point) as well as in the negative direction. -
Page 14: Description Of Signal-Leds
Fig. 4: Signal LEDs 5 Integration in a PROFINET-network The force measuring amplifiers of the EMGZ490A series were design to work in an PROFINET-network whereas the amplifier acts as an IO-device (Slave) and die IO- Controller (or PLC) as a master. -
Page 15: Tcp/Ip Configuration
The IP-address is assigned to each device via the PLC. The device must have an IP-address of 0.0.0.0 after power up to enable the assignment of the final IP-address. This is the case after each EMGZ490A restart. Static IP-address: A static IP-address is required to enable the PLC accessing a web interface. -
Page 16: Configuration
Operation Manual EMGZ490A 6 Configuration The configuration of the EMGZ490A can be performed either over a web interface or over PROFINET. In both case the same parameters are configured. 6.1 Description of Parameters PROFINET Filter Use: The amplifier provides a low-pass filter for PROFINET data to prevent noise and interferences being overlaid to the PROFINET output. - Page 17 Operation Manual EMGZ490A Tension at Max. Output Use: This parameter defines what force value (N, kN, lb, g, kg) corresponds to the maximum output of the amplifier (10V). Note: By changing the units to lb the whole unit system will change from metric to imperial units.

Page 27: Web Interface
Using the web interface requires knowledge of the IP address. Your IT system administrator can provide information about the assigned addresses. After entering the IP address in your web browser the home page of EMGZ490A will appear (see Fig. 10). Caution The web interface may only be used in the test mode since data communication can interfere with the PLC. - Page 28 Operation Manual EMGZ490A The web page Current Reading shows the actual values of the amplifier. The first line “Tension” shows the tension at the input in the configured unit of measure. In the second line “Output” indicates the output voltage shown in Volt.
