WARNING
This information indicates particular danger to life and
health. Disregarding such a warning can lead to serious or
fatal injury.
CAUTION
This information indicates particular danger to the equip-
ment or other property of the user. Serious or fatal injury
cannot be excluded.
NOTE
These notes give important information on a certain
subject.
CAUTION
Installation, electrical connection and commissioning of
the electronic voltage regulator may only be carried out
by qualified, skilled personnel and only in accordance with
these operating instructions.
It is the responsibility of the user to make sure that the
electronic voltage regulator is used for the specific
application only. For safety reasons, any unauthorized and
improperly executed works, i.e. installation, modification,
alteration of the equipment, electrical connection, or
commissioning of the equipment, are forbidden without
first consulting MR!
The trouble-free operation of the drive, the on-load tap-
changer, and the transformer may be put at risk.
1.2
Specified application
The electronic voltage regulator TAPCON® 230 VC serves for
automatic control of transformers with a motor-driven on-
load tap-changer. The motor-drive mechanism receives the
corresponding control commands from the voltage regulator.
With these commands, the on-load tap-changer moves to
the next position and the transformer’s voltage value is
adapted to the preset desired voltage level.
To allow individual adaptation of the control system to the
various field service conditions encountered, influencing
variables such as time delay, bandwidth, and even line-
dependent and load-dependent parameters can be pro-
grammed for compensation of voltage-dependent and/or
current-dependent limits. As a special feature, the voltage
regulator is also capable of controlling parallel transformer
operation.
WARNING
All relevant fire protection regulations must be strictly
observed
