Connection
CAUTION
• Be sure to turn off the power of the controller before connecting/disconnecting
cables. Failure to do so may cause malfunction.
• Ensure that the orientation of the connector is correct. Otherwise the pin could break
and may lead to system malfunction.
• Part of each input/output circuit of the LK-G Series is internally common. Be sure that
no potential difference is generated between the common terminals due to the
potential difference between wires or external devices.
Refer to "Precautions for Wiring" (page 4) for details.
■ Connecting the head
Connect the connector of the head-to-controller cable to the head connector A or B on the
controller’s terminal panel. Check that a click sound is heard indicating that they are
securely fixed. When removing it, pull it out while pressing the buttons on both sides of the
connector. Up to two heads can be connected at the same time.
