CP1E CPU Unit Hardware User’s Manual(W479)
Check the following when replacing any faulty Units discovered during inspections.
•
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.
Precautions for Correct Use
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.
