Safety
1.1
Explanation of safety labels
The following safety labels relating to the operation of the
analog signal transfer unit for remote tap position indication
are used in these Operating Instructions.
These labels must be observed at all times!
ATTENTION!
Refers to a potentially hazardous situation that may result in damage to
the product or adjacent equipment.
NOTE
NOTE!
Risk of damage to the motor drive
unit, on-load tap-changer and
transformer!
The signal transfer unit may only be
used with the on-load tap-changer
specified in the order.
It is the responsibility of the user to
make sure that the signal transfer
unit is used for the specified application only.
For safety reasons, any unauthorised
work, i.e. installation, alteration, commissioning or modification of the signal transfer unit is forbidden without
first consulting MR.
Contains important information and
special notes.
1.2
Safety instructions
• All warnings and safety instructions must be observed
at all times!
Failure to follow the safety instructions may lead to
accidents and severe personal injury.
• Please read these operating instructions before
commissioning the equipment!
Read the Operating Instructions before commissioning the
analog tap position indicator. As the operator, you are responsible for ensuring that users of the equipment have
fully understood the operating and safety instructions.
• Train your staff!
Before asking staff to work with the analog tap position
indicator, provide training regarding general and special
safety instructions and accident prevention regulations.
• Only suitably qualified personnel should work with the
analog tap position indicator.
The analog tap position indicator is designed exclusively
for application in electrical or energy systems and facilities
operated by appropriately trained staff,
i.e. staff who are familiar with the installation, assembly,
commissioning and operation of such products.

Configuration / Types
Configuration / Types
For transformers where the transformer ratios are modified
through on-load tap-changers with remote-controlled motor
drives, the operating positions of the on-load tap-changer
have to be displayed in the control room.
Tap position indicator instruments with square or rectangular
design for constant current analysis require no additional
power supply unit.
The devices can be mounted with the two screw spindles provided. Insert the screw spindle into the bracket from the rear
of the device (plastic handle facing backwards) and turn it
sideways
• to the first recess (for control panel thickness up to 20 mm)
• to the second recess (for control panel thickness 20 - 40
mm).
Fold in the screw spindle and push the device into the control
panel cutout. Turn the screw spindle until it latches (90° angle
relative to the device) and tighten it manually or with a small
screwdriver.
NOTE
Before tightening the screw spindle
carefully move it back and forth in
order to ensure free movement.
NOTE
In a high-density installation the
screw spindles can be mounted between the devices, since they are diagonally offset.
The power supply unit is designed for top hat rail mounting
according to DIN EN 50022.

Principle and configuration
Principle and configuration
The tap position indicator instrument displays the current position of the motor drive or the on-load tap-changer at any
location, usually in the control room.
3.3
3.1
Terminals 17 (+) and 18 (-) (generally terminals X1:211 (-) and
X1:212 (+)) are connected with the output signal of the measuring transducer in the motor drive unit.
Principle
Each motor drive position corresponds to a contact area on the
position transmitter board that is contacted by the slider. The
contact areas are connected with the position transmitter module (resistor type) via the position transmitter cable.
In the position transmitter module a modified resistance value
is transferred to the input of a measuring transducer in the
motor drive unit, depending on the position. This measuring
transducer converts the resistor input signal into a constant
current signal (e.g. 4...20 mA). The input signal of the measuring transducer is generally specified with 10 ohm per step, the
output signal can be variable, usually 4...20 mA. The display
instrument is adapted to the output signal and therefore
indicates the motor drive position, depending on the constant
current signal.
3.2
Configuration
A resistor-type position transmitter position transmitter is
required in the motor drive unit. The resistor contact range (10
ohm per step) must match the number of required positions.
The motor drive unit also features a measuring transducer that
converts the resistor signal into a constant current signal
(4...20 mA).

Settings and adjustment
The tap position indicator instrument are preset and only
require fine-tuning
via the adjusting screw.
Fine-tuning
• Check the connection
• Move the motor drive unit into the minimum switching position
• Set the position indicator to the centre of the minimum
scale value using the adjusting screw
• Move the motor drive unit into the maximum switching
position
• Check the display and readjust if necessary
The output signal of the measuring transducer is connected
with the display instrument via a signal line.
