in the „RCC“-mode (see par. 53), depending
on the metering rate 2 parameter setting and
state, the actual value of target PF is defined
by setting of the „remote controlled target
PF“ (par. 80) and by actual state of the
„remote controlled PF serial number“ (par.
81)

when the metering rate 2 parameter enabled
(value "1" or "E") and the "RCC"-mode (par.
53) enabled, PF control is carried out by the
„remote controlled target PF“ when the
metering rate 2 just active only (i. e. when
digital input activated or active power export
occurs ); for metering rate 1, the PF is
controlled by the target PF for metering rate
1 (par. 01), regardless to the „remote
controlled target PF“ value

Alarm No. 15 is activated when no response
from the NRC86 unit occurs during approx. 20
seconds. The alarm actuation function is
intended mainly for the „I/O“-mode.
