  • Page 42 Section 2 1MRS758755 A REC615 and RER615 overview Audit trail is a chronological record of system activities that allows the reconstruction and examination of the sequence of system and security-related events and changes in the protection relay. Both audit trail events and process related events can be examined and analyzed in a consistent method with the help of Event List in LHMI and WHMI and Event Viewer in PCM600.
  • Page 43 Section 2 1MRS758755 A REC615 and RER615 overview PCM600 Event Viewer can be used to view the audit trail events and process related events. Audit trail events are visible through dedicated Security events view. Since only the administrator has the right to read audit trail, authorization must be used in PCM600.

The type is selected by setting jumpers X19, X20, X21 and X26. The jumpers are set to EIA-232 by default.
  • Page 782 Section 13 1MRS758755 A Protection relay's physical connections To ensure fail-safe operation, the bus is to be biased at one end using the pull-up and pull-down resistors on the communication module. In the 4-wire connection, the pull- up and pull-down resistors are selected by setting jumpers X5, X6, X8, X9 to enabled position.
