tap position, operation command signals, various status signals, alarm signals, etc., for connection with other intelligent devices (LED) The network port can also be used with another YK-6 controller port to connect to run in parallel functions Prompt： The maximum number of controllers that can parallel connection and using network ports is 5.5 When sampling the voltage input, connect the potential transformer PT, the access range is AC 0-500V Prompt： Only the realization of automatic voltage regulator control access to the sampling voltage 5.6 Ground mark " " must be reliably grounded 6.Controller interface and parameter settings The controller uses 4.3-inch LCD touch 6.1 Turn on the main interface Power on the controller after the main interface appears Setting Search Alone Manual 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 the interface does not display this mark mark is displayed and flashes, otherwise Prompt: In all the settings and query interface are blocked → N, N → 1, STOP instruction operation, only in the main interface can be instruction operation 6.2 User interface Setting Search Alone Manual Run ID: Displayed while the tap switch is running Displayed displayed when N→1 6.3 Query Interface After touching the mark when 1→N, on the home screen, the query interface is displayed Prohibit operation Parameter Log Prohibit operation 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 工作状态 Working status

controller 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

Page up Page down There are a maximum of 10,000 log records Users can query records of operations or failures for a long time as needed 6.6 Parameter Setting Interface After to touching the displayed on the home screen, the parameter setting interface is Parameter Setting Working model Instruction selection Time setting Net parameter Prohibit operation Disable operation identification: " " mark appears during all parameter setting, and latch → 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 Working Mode Selection Alone Parallel master Parallel slave Prohibit operation Confirm 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 Communication address Prohibit operation Confirm 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 Instruction selection Manual Auto Remote Prohibit operation 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 Confirm Setting value Setting parameter Unit Range Step size Content Setting voltage Precision of voltage regulation Delay Prohibit operation 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 Setting Search Alone Auto Setting voltage Actual voltage 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 Setting Search Parallel unit Parallel master Manual Out of step 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 Prompt: After the mark is displayed, all → N, N → 1, and STOP instructions are operated, and the controller sends an out-of-step alarm signal Synchronization corrections need to be set up to be manually corrected individually 6.13 Participate in parallel

selection "parallel main" also need to participate in the parallel number of slaves to choose from Prompt: It is also necessary to reset the command selection after returning from the "slave slave" operation mode to other operating modes 6.14 Time setting interface Year Month Day Time Prohibit operation Confirm 6.15 Network Parameters Interface Prohibit operation In the TCP / IP settings, the IP address is the IP address of the controller If you need to access the unit by IP address, set the corresponding address 7 Operating and maintenance 7.1 The user to install the correct wiring and the corresponding parameter settings can be put into use after the controller 7.2 controller in use, should always be kept clean, there should be no conductive dust covering the body and the terminal
