A: System Description:
Joint control is the air compressor air compressor to run my company KY02S an important function of the controller. Air compressor used in the formation of a multiple supply network, gas cylinders to the same place. Air compressor controller address sequentially numbered starting from 1, the network allows a maximum of 16 air compressor controller, Unit 1 is set to host the rest of the air compressor is set to slave, the master control to set load-line pressure unloading pressure, the number of online and on-line control of Taiwan, the delay time. The host starts, automatically enter the online control mode.Comparison of gas pressure and the pressure line control settings, select the network to send control commands in the air compressor, air compressor control network in the start-stop machine automatically stable air pressure, balance the network of the air compressor running time. Coordinated control can start and stop frequently to avoid air compressor, damage equipment and reduce the impact on the power grid to save energy.
II: System Settings:
1: Host settings: state of the device is stopped, press "↓" key to enter the following interface. Select User Preferences.Press "→" key to enter the preset mode of operation, set the communication is: linkage. Communication code set: 0001,return to the user interface parameters, select the linkage parameters preset, press the "→" into the linkage parameters, the linkage status set to: host, the linkage is set to start and stop: the order of rotation time, the number of linked machines, the linkage pressure limit, upper pressure limit linkage, linkage delay time set according to the actual situation. Note (linkage and linkage pressure limit Pressure limit value should be loaded in the gas pressure and gas pressure between unloading)
2: From the machine settings: state of the device is stopped, press "↓" key to enter the screen shown above. Select User Preferences. Press "→" key to enter the preset mode of operation, set the communication is: linkage. Communication code from 0002-0016, (note that two devices are not allowed in the network encoding the same). Back to the user interface parameters, select the linkage parameters preset, press the "→" into the linkage parameters, the linkage status to: from machine. Linkage from the machine start and stop, rotation time, the number of linked machines, the pressure limit of linkage, linkage pressure limit, so do not set the delay time interaction.
Three: Network Connection:
Joint control network requires the use of good communication cable shielding effect of the air compressor to run the network controller's communication port A, B parallel, to avoid routing over Cheng Zhongyi strong electrical interference. Signal line and power line got all different channels. Network diagram as shown below:
Four: Run the linkage control:
Set up a network user to confirm the linkage of the air compressor control parameters, connect the communication line, start the host, the system automatically enters the linkage control state. Host interaction parameters set by the user to send control commands to control the network from the machine stops, loading and unloading, holiday and so on. Stop when the user presses the host linkage control stop button to stop the control linkage. Network stopped, shut down from the machine need to manually press the stop button.
V: For example:
A user has an existing air compressor to the same four gas cylinders, pressure tank to maintain hope in between 0.6MPa to 0.85MPa. Linkage set as follows:
1: debug each, respectively, to enable normal operation of the compressor. In air compressor control panel display device has stopped into the user parameter entry, select the preset pressure and temperature. Interface into the preset pressure and temperature, pressure, respectively, upper and lower set pressure. In this example we will limit the pressure0.85MPa. Pressure limit is set to 0.6MPa. Practical application of models based on user selected, and the gas consumption set is different.
2: enter the user parameter option. Select the preset mode of operation, setting the interface into the operating mode, set the communication mode for the interaction, communication code set 001,002,003,004, respectively. Select the communication code set to 001 air compressor, into the transport parameter setting interface, linkage status to the host,the linkage pressure limit is set to 0.82MPa, joint pressure limit is set to 0.63MPa, the rotation time is set for two hours, setting up several joint for the 004, the linkage is set to 0040 seconds delay time. Completion of the host settings.002,003,004, respectively, into the communication code to set the number of the linkage of air compressor set interface, set the linkage status is from the machine to complete from the machine's settings. Then cut off all power controller for a few seconds, then power.
3: According to the compressor location, a good shielding effect for the four communication lines. Four, respectively, the display panel and air compressor for the A and B label the terminals connected in parallel. Complete the network installation setup.
5: Start the communication code to the host 001, the system automatically enters the joint operation. Host interaction according to their own supply pressure and minimum pressure and maximum pressure linkage compared to select the air compressor to take the network to send control commands. Tank in order to maintain stable pressure.
6: stop the network: the user presses the stop button on the host, the host stops. Will no longer host the next crew on the network to send control commands.
A user has two existing air compressor to the same gas tank, hoping to maintain the pressure in the tank between 0.6MPa to 0.8MPa. Gas consumption according to the user, usually only one air compressor work, a backup, when a continuous work 5 hours later, another startup, when a machine fails, another machine to work, the linkage setup as follows:
1: debug each, respectively, to enable normal operation of the compressor. In air compressor control panel display device has stopped into the user parameter entry, select the preset pressure and temperature. Interface into the preset pressure and temperature, pressure, respectively, upper and lower set pressure. In this case we limit the pressure of 0.8MPa.Pressure limit is set to 0.6MPa. Prac
