13-1-2 Unit Replacement Precautions
Check the following when replacing any faulty Unit.
• Do not replace a Unit until the power is turned OFF.
• Check the new Unit to make sure that there are no errors.
• If a faulty Unit is being returned for repair, describe the problem in as
much detail as possible, enclose this description with the Unit, and return
the Unit 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 Unit.
Note
When replacing a CPU Unit, be sure that not only the user program but also
all other data required for operation is transferred to or set in the new CPU
Unit before starting operation, including DM Area and HR Area settings. If
data area and other data are not correct for the user program, unexpected
accidents may occur.
