Transformator switching relay | Type TSRD
With TSRD the both three-phase transformers and combinations of three individual single-phase transformers can be switched-on in a three-phase network without inrush currents arising. The required application is selected using DIP-switches.
Note in safety
Potential separation does not occur during switching of the TSRD as additional RC elements are connected between the
input and the output thyristor clips. To bypass the thyristors, a bypass contactor must be connected in parallel to the TSRD.
General
The required application is selected using DIP-switches. In the case of applications N and L the transformer core type must
be selected at TP1 (transformer type) The TSRD has a Message Display Output (Message 1). Depending on the DIP-switch
selections four different conditions can be displayed. The DIP-switches should be set only when the power is off.

7/8 Applications
7 8 Application type:
OFF OFF D, Three-phase transformer, delta or star cong. without MP
ON OFF S, Three-phase transformer, star conguration with MP
OFF ON N, 3 Single phase transformer between phase and N
ON ON L, 3 Single phase transformer between two phases
Setting premagnetisation on the trimming potentiometer depending on transformer type
On the trimmer potentiometer TP1 the transformer core type of the single-phase transformer being used
for application N or L must be set. For applications D and S the trimmer function does not apply.
> Toroidal core transformers set to position R
> Coil form (shell) transformers (stack-core transformers): Set to position P (factory setting)
> The correct position for stack-core transformers (P) can vary between the „10- and 2 o’clock „ position.
> Strip-wound cut core transformers: Potentiometer setting between the „P“ and „R“ settings
Messages
The LED „Message Display 1“ (yellow) is illuminated, when the relay contact between the
terminals 23 and 24 is closed. The Message Display1 can be applied for various functions.
Fully-On message: The relay contact is closed, as soon as the connected transformer has been
fully switched-on by the TSRD when the premagnetisation (remnance setting) is completed.
OK message: The relay contact is closed after power is supplied to the TSRD and initialisation is
complete . On malfunction the contact is opened.
Error message: On malfunction the contact is closed.
Bypass contactor: The relay contact is used to control a bypass contactor, used to bridge the control elements.
OK-LED
The LED OK (green) is illuminated when the TSRD is in the ‘OK’ status. Malfunctions are indicated by different ashing
rates.
Flashing rate Interference
continuous OK state
10 Hz A remote-on signal has been applied, and no automatic resetting after malfunction (DIP1=Off)
5 Hz Three-phase network is counter-clockwise, and switching-on only for clockwise phasesequence (DIP2=Off)
1 Hz The supply voltage is outside the limiting voltage values (-20/+15% of U
rated)
10 Hz Internal error
Additional information
> Bypass-contactor: To protect the safety coil it is recommended to connect an RC-element parallel to the coil.
> Fuse: The need in the data sheet under „Current“ dened limits are met. If this is not possible, the TSRD should accor-
ding to the circuit example (see last page) are connected.
