4.5.4 Position transmitter equipment
NOTICE
Damage to the on-load tap-changer and motor-drive unit!
Damage to on-load tap-changer and motor-drive unit due to incorrect use of
position transmitter equipment.
► Only circuits stated in the chapter Technical data for position transmitter
equipment [►Section 14.3, Page 380] may be connected to the position
transmitter module connections.
► The switchover point of the position transmitter equipment in the motor-
drive unit is not the same as the switchover point of the diverter switch
operation. This depends on the type of diverter switch. This fact should
be noted when project planning the locking circuits between the motor-
drive unit and external equipment (e.g. transformer circuit breaker).
► Therefore, the "Tap changer in operation" position transit contact shown
in the connection diagram should be used for external monitoring, locking
and control purposes instead of the position transmitter equipment.
The position transmitter equipment is used to indicate the operating position
of the on-load tap-changer/de-energized tap-changer when idle.
The remote displays are available in various versions.
The position transmitter module for connection by the customer is located on
the terminal rail [►Section 4.5.3, Page 32].
For more information about the position transmitter equipment, see Techni-
cal data for position transmitter equipment [►Section 14.3, Page 380].
