Page 4: Safety Instructions
Operating Manual EMGZ 321 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
In any case the power supply must be disconnected from the main supply before opening the housing. Proper function of the FMS tension controllers is only guaranteed with the recommended application of the components. In case of other arrangement, heavy malfunction can be the result. -
Page 6: System Description
Operating Manual EMGZ 321 2 System Description 2.1 Functional Description The EMGZ321 is a double channel strain gauge amplifier for a single measuring point. The material tension can be measured on both sides of the measuring roller independently. The 2 force sensors of the measuring point measure the tension force in the material and transmit the measuring value as a mV signal to the electronic unit EMGZ321. -
