2.3. Electrical connection
2.3.1. Connection notes
-
In order to avoid electrical noise to the input signal, the signal line should be away from the power line.
-
If the AC power supply is connected to the I/O terminals or DC supply terminals, the tension controller will be burn out.
-
Connect the tension sensor according to the wiring diagram, pay more attention to the wiring of tension sensor if two tension sensors are connected otherwise the measurement value will be incorrect.
-
When one tension sensor is used, make sure to short-circuit the unused tension signal terminals.
