12-3-3 Handling when Replacing Units
Networks are constructed from a Master Unit and Slave Units. If a Unit is mal-
functioning, the entire network will be affected. The malfunctioning Unit must
be replaced quickly. To restore network functions as quickly as possible, it is
recommended that spare Units are kept on hand ready to replace malfunc-
tioning Units immediately.
Precautions When
Replacing Units
Heed the following precautions when replacing nodes after a periodic inspec-
tion has revealed a problem.
Check that the new Unit does not have errors after replacement.
If returning malfunctioning devices for repair, attach a detailed description of
the malfunction to the device and send the device to the OMRON representa-
tive listed at the end of this manual or to your OMRON representative.
If contacts are defective, wipe them with a clean pure cotton cloth that has
been soaked in industrial alcohol.
