[3] Check the wires and terminals for looseness and other problems. -
Page 49: Unusual Check
• If fluctuations do not occur during manual operation, this is generally caused by high control gain set by the LE-30CTN tension controller. In this case, please adjust the control gain factor refer to Sec. 5.5. • Check that the output set for the OFF status of the [RUN] input signal is After replacement of the optimum for the reel diameter of the replaced material. -
Page 50: Cleaning
• Check that the voltage is approximately 5 VDC between the terminals [RED] and [BLK]. If no voltage is output, disconnect the wire, and check the voltage. No voltage is output after disconnecting the wire, the LE-30CTN tension controller is defective. If voltage is output after disconnecting the wire, the external wiring or the tension detector is defective. -
