The Controller Link Unit is a Network device. If the Unit is damaged, it will
effect the entire Network, so always ensure repairs are undertaken immedi-
ately. We recommend that you have a spare Controller Link Unit on hand so
that repairs may be conducted quickly.
Observe the following precautions when replacing the Unit.
• Always turn OFF the power before replacing the Unit.
• Check that the new Unit is not faulty.
• If you suspect that a poor connection is the cause of a malfunction, clean
the connectors using a clean, soft cloth and industrial-grade alcohol.
Remove any lint or threads left from the cloth, and remount the Unit.
• When returning a faulty Unit for repairs, always attach a detailed fault
report to the Unit and return to you nearest OMRON outlet as listed at the
back of this manual.
1. In order to prevent faulty operation be sure to turn off the power to all nodes
before replacing the Unit.
Relay Terminal Blocks (CJ1W-TB101) can be used on any node but the
end nodes to enable replacing the Controller Link Unit with the communi-
cations cable connected and turn OFF the power to only the Unit being re-
placed. Refer to Appendix C Using the Relay Terminal Block for details.
2. When replacing the Unit, do not reconnect that node to the Network before
carrying out the procedures listed below. In particular, a node with a small
address will become the polling node and communicate the initial network
parameter status to other nodes, so there is the chance that network pa-
rameters in the entire Network will be damaged.
