ABB Switzerland Ltd REG 316*4 1MRB520049-Uen / Rev. C
7-20
Either the 316VC61a or 316VC61b unit or the complete equip-
ment has to be replaced in the case of error messages con-
cerning the main or logic processors.
Should the diagnostic function report an error in the A/D proces-
sor (type 316EA62) although none is fitted, the message can be
ignored. If one is fitted, however, it must be replaced.
An entry is made in the event list every time the protection is re-
started.
