2.2.2 Connecting Visual KV Series Expansion Units
• Connect a basic unit and an expansion unit with an expansion cable.
• An expansion cable approximately 60 mm long is provided as standard.
• When extending the expansion cable, use long expansion cables (300 mm)
(OP-35361).
• Up to two expansion cables (300 mm) can be connected to one basic unit.
• The READY/ERROR LED is lit during normal communication, flashes when an
abnormality occurs, and is not lit when the power is not supplied correctly. If this
LED is not lit, check whether the expansion cables are correctly connected.
Be sure to turn off the power before connecting or disconnecting expansion
cables. If they are connected or disconnected while the power is on, the units
may be damaged or fail.
Note: Keep noise sources such as power cables and electromagnetic switches away
from expansion cables (300 mm) as much as possible.
