10-1-2 Module Replacement Precautions
Check the following after replacing any faulty Module.
• Do not replace a Module until the power is turned OFF.
• Check the new Module to make sure that there are no errors.
• If a faulty Module is being returned for repair, describe the problem in as
much detail as possible, enclose this description with the Module, and
return the Module to your OMRON representative.
• For poor contact, take a clean cotton cloth, soak the cloth in industrial
alcohol, and carefully wipe the contacts clean. Be sure to remove any lint
prior to remounting the Module.
Note (1) When replacing a Coordinator Module or Motion Control Module, be sure
that not only the user program but also all other data required for opera-
tion is transferred to or set in the new Coordinator Module before starting
operation, including DM Area and System Setup settings. If data area and
other data are not correct for the user program, unexpected operation or
accidents may occur.
(2) The System Setup is stored in the parameter area within the Coordinator
Module or Motion Control Module. Be sure to transfer these settings to
the new Coordinator Module or Motion Control Module when replacing a
Module.
(3) After replacing a Motion Control Module, always set the required settings.
(4) In some cases, parameter data used in the Motion Control Modules is ac-
tually stored in the Coordinator Module’s DM Area, so be sure to transfer
the DM Area settings when replacing a Coordinator Module.
4 Installation and
wiring Check that each Module is
connected and locked to the
next Module securely. No looseness Press the connectors together
completely and lock them with the
sliding latches.
Check that cable connectors
are fully inserted and locked. No looseness Correct any improperly installed
connectors.
Check for loose screws in
external wiring. No looseness Tighten loose screws with a Phil-
lips-head screwdriver.
Check crimp connectors in
external wiring. Adequate spacing between
connectors Check visually and adjust if neces-
sary.
Check for damaged external
wiring cables. No damage Check visually and replace cables if
necessary.
