ARCSARC has two analog group inputs which must be properly configured.
| Input | Description |
|---|---|
| I3P 1 | Three-phase currents, necessary when the operation mode "Light +current" is used |
| IRES 1 | Residual current (measured and calculated) |
Note: See the preprocessing function blocks in this document for the possible signal sources. The GRPOFF signal is available in the function block called Protection.
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.
1 Can be connected to GRPOFF if "Light only" or "BI controlled" operation modes are used
