REX610 Technical Manual

PREVPTOC has one analog group input which must be properly configured.

Table 1. Analog inputs
Input Description
I3P Three-phase currents
Note: See the preprocessing function blocks in this document for the possible signal sources.

Improper analog channel configuration causes a validation error if the analog channels are not completely configured or they do not match with certain settings. For troubleshooting, check the contents of this chapter and also the preprocessing blocks in this document. The configuration can be written to the protection relay once the mismatch is corrected.
