Observe the following precautions when replacing a WT30 Terminal found to
be faulty during inspection or by other means.
• After replacement make sure there are no errors with the new WT30 Ter-
minal.
• When a WT30 Terminal is being returned for repair, attach a sheet of
paper detailing the problem and return the WT30 Terminal to your
OMRON representative.
• If there is a faulty contact, try wiping the contact with a clean, all-cotton
cloth dampened with alcohol.
OFF the power supplies before removing the faulty WT30 Terminal.
The procedure for replacing I/O Slave Stations registered in the scan list is
explained here. When replacing I/O Slave Stations that are not registered in
the scan list, registration at the Serial Master Station is not required. Before
replacing the I/O Slave Station, set the node number, frequency channel, and
function setting switch. Then, either cycle the Serial Master Station power or
change the mode setting switch.
1. Before turning ON the power, set the function setting switch to the same
setting used before replacement.
