6. Description and Principle of Operation
The LVRSys™ regulator concept is based on a linear regulator. By coupling and uncoupling two transformers with a selected transfer ratio, the output voltage can be regulated in several (e.g. 9) steps. The maximum control range depends on the version (e.g. from ±6% up to ±20%).
The transformers are controlled by thyristors. The stages of the transformers are determined by the thyristors' switching settings.
Step Transformer 1.5%/2.5%
Transformer 4.5%/7.5%
-6% -1.5% -4.5%
-4.5% 0% -4.5%
-3% +1.5% -4.5%
-1.5% -1.5% 0%
0% 0% 0%
+1.5% +1.5% 0%
+3% -1.5% +4.5%
+4.5% 0% +4.5%
+6% +1.5% +4.5%
Table 6-1 Generation of the voltage levels in steps
The control signals for the thyristors are generated by driver circuits that switch them intelligently. By monitoring the magnetic flux in the transformers, the transformers can be switched without voltage dips, current increases or generating harmonics.
The step change required is output by the controller. The controller can determine the step based on the bus bar voltage or the output currents.
All three phases are regulated independently of one another. This helps improve the symmetry of the grids.
The safety contactor activates automatically in the event of a failure. This ensures that the transformers are shorted and as such the low-voltage grid will operate unregulated.

Figure 6-2 Example of 3% voltage reduction
In the example shown in Figure 6-2, the output voltage is reduced by 3% compared with the input voltage. The transformer 4.5% TR converts the primary voltage, which is switched by thyristors, in a negative direction and subtracts 10.35 V (4.5% of 230 V) from the output voltage. The transformer 1.5% TR converts the primary voltage in a positive direction and adds 3.45 V (1.5% of 230 V) to the output voltage.

10.13.2.4 CSV configuration of the IEC 60870-5-104 Slave
The LVRSys IEC 60870-5-104 Slave can be configurd by using a CSV file. When starting the system, the CSV file will be loaded and the IEC 60870-5-104 slave is then ready for use.
In the standard lvrsys_t104_target.csv all possible configurations are described. The desirec changes must be made directly in the file, using the following steps:
Get CSV-File lvrsys_t104_target.csv from A. Eberle Support-Team.
Adjust CSV-File as desired with Notepad or MS Excel.
Save CSV-File as lvrsys_t104_target.csv (MS-DOS File if MS Excel is used) on a FAT32
formatted USB stick.
Connect USB stick to LVRSys™.

0 T104 Station CA is the IP address of the allowed station (ASDU)
Default is 1 (Each station allowed).
0 T104 TCP/IP Port Address of the 1st. instance of the T104
Default is 2404.
0 Timeout (T104 Timeout. Param.)

0 T104 IP Bind (enabled only in redundant systems)
LVRSys IEC 60870-5-104 slave can be linked in the first instance to a system IP. This is useful if redundancy systems are used to communicate or there is an additional connection via other networks such as WLAN or UMTS. LVRSys IEC 60870-5-104 slave reads only the first instance.
In redundant systems with different IP addresses and the same port address
T104 IP Bind must be activated.
0 T104 redundancy
Figure 10-22 parameter overview IEC 60870-5-104
10.13.2.6 Redundancy System
0 LVRSys IEC 60870-5-104 slave can use five IEC 60870-5-104 connections simultaneously.
0 Each instance has ist own IEC 60870-5-104 process images and messages.

We take care of it.
LVRSys IEC 60870-5-104 slave does not hold any events or messages in the queue. When the connection is available again messages will be transmitted and the process informations renewed.
If there is no connection the LVRSys IEC 60870-5-104 slave will not renew process
information and collect any messages. Once the connection is available again,
the LVRSys IEC 60870-5-104 slave renews process information and transmits new
messages.
The redundant instances are always connected to the set IP addresses! If no IP
address is set, the instances connect to all networks (IP = 0.0.0.0).
In redundant systems with different IP addresses and the same port address the
T104 IP Bind must be enabled. Otherwise the first instance will connect with all
the networks and the other instances cannot connect.

11.8 Lightning protection
The lightning and surge protection is in all systems coordinated according to EN 61643-11 type 1 + type. 2
Figure 11-7 LIghtning protection Type 1 DV M TNC 255 FM (951305)
In case of persistent lightning strikes, the use of lightning protection module turns red. The LVRSys goes to automatic bypass mode and disconnects the electronics from the grid. To remedy the error follow the steps:
Take LVRSys out of operation (See sec. 9.2).
Replace Lightning exchange (DV MOD Art. 255 951 001).
Put LVRSys only after instruction in operation (See sec.9.1).
