ibility of adverse effects on the diesel-generator units. Failures in the indication equipment should not result in diesel-generator unit failure or bypass of the diesel-generator unit, and the bypass indication should not reduce the required independence between redundant diesel-generator units. 2.5. The indication system should include a capability of ensuring its operable status during normal plant operation to the extent that the indicating and annunciating function can be verified. 6. Regulatory Guide 1.9, positions C.1.6 through C.1.8 contain further guidance that should also be addressed regarding status and anomalous conditions indication and alarms for diesel-generators.60 3C.
