to connect to run in parallel functions

5.5 When sampling the voltage input, connect the potential transformer PT, the access range is AC 0-500V

5.6 Ground mark " " must be reliably grounded

6.Controller interface and parameter settings

The controller uses 4.3-inch LCD touch

The maximum number of controllers that can parallel

connection and using network ports is 2

Prompt：

6.1 Turn on the main interface

Power on the controller after the main interface appears

System fault: When controller detects a fault in local electric mechanism,

mark is displayed and flashes, otherwise the mark is not displayed on the interface Communication failure: When controller has a problem with local electric mechanism

communication connection, the mark is displayed and flashes, otherwise the interface does not display this mark

Prompt:

In all the settings and query interface are blocked 1 → N, N → 1, STOP

6.2 User interface

Run ID: Displayed while the tap switch is running Displayed when 1→N, displayed when N→1

6.3 Query Interface

After touching the mark on the home screen, the query interface is displayed

6.4 Real-time parameter display interface

When the “Parameter” icon is touched on the query interface, the real-time parameter display interface is displayed

参数 Parameter

Working status: There are three kinds of status: local, stop, and remote

Instruction selection: There are three states: manual, automatic, and remote

Lock state: There are two states, unlock and lock (For external access blocking signal detection)

Running status: There are two kinds of status, they are in place and running

Control status: There are two kinds of status: ready and fault

Fault type: There are three types of status, namely, open/closed, power failure, and self-test failure

Communication address: The communication address between this controller and the local ZDK controller It is set to "1" at the factory

6.5 Log Display Interface

When the "Log" icon is touched on the query interface, the log display interface

6.6 Parameter Setting Interface

After to touching the on the home screen, the parameter setting interface is displayed

Disable operation identification: " " mark appears during all parameter setting, and latch 1 → N, N → 1, STOP instruction operation

6.7 Working Mode Selection Interface

The operating mode selection interface is displayed after touching the "operation mode" mark under the parameter setting interface

In this interface, the "Alone" mode is the default setting of the controller When parallel control is required, "parallel master" or "parallel slave" is selected

6.8 Communication Address Setting Interface

When the “parallel slave” icon is touched under the operation mode selection interface, the communication address setting interface is displayed

In parallel operation, when the controller is set to "parallel master", the controller

communication address defaults to 01; when the controller is set to "parallel slave",

the communication address needs to be reset, and all slave address codes participating

in the parallel connection must not be repeated

6.9 instruction selection interface

When the “Instruction Select” icon is touched under the parameter setting

interface, the command selection interface is displayed

The "Manual" mode under this interface is the controller default setting

6.10 Automatic Mode Parameter Setting Interface

The automatic mode parameter setting interface is displayed after touching the

"automatic" mark on the instruction selection interface

Only the setting value field needs to be set in this interface

Delay time setting: Set according to the required operating frequency of the switch in the range of 5-180S; set the delay time, it must be more than 10 seconds Under the premise of guaranteeing the power supply quality, set the delay time as long

as possible This can avoid frequent tap changer operation and extend the life of the switch

Setting voltage and voltage regulation accuracy settings:

Connect a sampling voltage of 100V; adjust the output voltage of the regulator so that the output voltage deviates from the ±2.5% voltage value of the 100V sampling voltage, that is:

Lower limit voltage = setting voltage - setting voltage × pressure regulation accuracy;

The upper limit voltage = setting voltage + setting voltage × precision of voltage regulation;

Example: setting voltage is 100V, voltage regulation accuracy is set to 2.5%; Then: the lower limit voltage = 100V-100V × 2.5% = 97.5V;

The upper limit voltage = 100V + 100V × 2.5% = 102.5V;

When the sampling voltage is lower than the set lower limit voltage, the controller itself issues a "1→N" command;

When the sampling voltage is higher than the set upper limit voltage, the controller itself issues an "N→1" command;

After the delay time set by the controller is delayed (for example, 10 seconds delay), the switch shall switch to the corresponding 1→N or N→1 direction synchronously, and adjust the voltage to “set voltage”=“actual” The output voltage" realizes the automatic control of the output voltage of the transformer system

6.11 Auto-adjusting the main interface

When the YK-6 controller operates in the auto-regulation mode, a real-time

histogram will appear below the number of tap positions Both sides of the histogram

display the real-time values of the setting voltage and the actual voltage when the

sampling voltage is within the setting range The bar graph is green when there is no

need to regulate the voltage, and it is red when it is out of the setting range When the

sampling voltage exceeds the setting range and the corresponding delay time is

performed, the pressure adjustment command is automatically issued

6.12 Parallel Voltage Regulator Main Interface

When the YK-6 controller is operating in the shunt regulator mode, the

mark is displayed on the left side of the screen

When the controller participating in the parallel connection loses

synchronization, the mark is displayed at the bottom right of the interface

6.13 Participate in parallel interface

After touching the mark on the main interface of the parallel voltage regulator, the participating parallel interface is displayed
