the transformer and the set bandwidth.
26 Switching direction con-
trol
The target tap position has not been
reached.
Check the RAISE/LOWER contact con-
nections and the functionality of the tap-
changer control.
27 Lower bandwidth limit
value
Value has fallen below the lower band-
width limit value.
The bandwidth is set too low. Check the
parameter.

value
Value has exceeded the upper band-
width limit value.
The bandwidth is set too high. Check the
parameter.
29 Switching interval moni-
toring: Total tap-change
operations

change operations has been exceeded.
Check the set number of LOWER tap-
change operations and the current oper-
ating conditions of the affected grid sec-
tion.
31 Switching interval moni-
toring: Raise tap-change
operations
