The active operation mode can be read from the monitored data OPR_MODE_STS.
Command exclusion
An active operation mode change using three inputs (
PARALLEL
,
AUTO
,
MSTR_TRIGG
and setting group change either by input or via menu) is needed when the active
operation mode must be changed automatically, that is, there is a logic which drives
these three inputs based on the status information from the circuit breakers.
The common Local/Remote (L/R) exclusion concerns the manual raise and lower
commands of OL5ATCC, that is, it internally provides the exclusion mechanism to
prevent remote commands (from SCADA) when the protection relay is in local mode
and vice versa.
9.10.5.4 Manual voltage regulation
The manual raising and lowering commands can be given via the configuration
inputs
LOWER_LOCAL
and
RAISE_LOCAL
, via the HMI of the protection relay or via

The master role is set on rising edge and internally kept until another parallel transformer
assumes the master role, or the operation mode is changed.
