Calibration Methods

The Calibrating procedure (setting the Gain), adjusts the controller and force sensors
so that the output gives you the actual tension value. There are two methods of
calibrating the system. The first method uses a defined weight. 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. 12) since it delivers the most accurate results.

Calibration Procedure
1.
The calibration of the sensors must be performed with the PLC
2.
Load a rope on the roller with the weight corresponding to your calibration force.
The roller configuration must correspond to the real material path in the machine
(wrap angle, distances between the rollers etc.).
3.
The RTM MP-system will deliver tension raw data via the corresponding output
4.
Enter the force data in your PLC and calibrate it matching your controlling needs.

Relay Output for Lost Communication
The relay output on the receiver EMGZ482.MP.R is deactivated, if the communication
link between receiver and transmitter is lost. For the technical specification of the
relay output see chapter 8“Technical Data”, Table EMGZ482R.MP.
