In Installations where two or more drives are programmed to perform the same job, and one installation works fine but the other one is encountering difficulty, the EPM allows the drive programming to be targeted or eliminated as a potential cause of the problem. Simply by switching EPMs between the working and non-working units, you can determine the cause of the failure.
