ABB ret650 - Connection between TR8 ATCC and TCMYLTC

Via a mA input signal
12.3.4.3 Connection between TR8ATCC and TCMYLTC
The two function blocks Automatic voltage control for tap changer, TR8ATCC and
Tap changer control and supervision, 6 binary inputs TCMYLTC are connected to
each other according to figure
153 below.
(Rmk. In case
of parallel
control, this
signal shall
also be
connected to
HORIZx input
of the parallel
transformer

Figure 153: Connection between TR8ATCC and TCMYLTC
The TR8ATCC function blocks have an output signal ATCCOUT, which is
connected to input YLTCIN on TCMYLTC. The data set sent from ATCCOUT to
YLTCIN contains 5 binary signals, one “word” containing 10 binary signals and 1
analog signal. For TR8ATCC data is also sent from output ATCCOUT to other
TR8ATCC function input HORIZx, when the master-follower or circulating current
mode is used.
