Connection / Wiring
Please refer to the "Practice Guide of Web Tension Measurement and Control" for wiring instructions
and the selection of the most suitable mounting location of the amplifier.
Very important:
Connect the shield of the sensor cable single sided on the amplifier side to protection
earth (PE) with low resistance. Connect GND separately from the shield with PE.
Additional recommendation: Connect the 0 V of the 24 V circuitry at a defined place prefably in close
proximity of the PE. If this reference point is to be operated in the "floating point" mode, then the voltage
between 0 V and PE should not exceed 50 Vpp.
The four terminal blocks with five
terminals each can be separatly
plugged in, simplifying trouble
shooting in case of faults.
