The thyro-AX controller is a component which may only be used to control and regulate electric energies in industrial alternating or three-phase networks. The Power Unit is suited for single phase loads.
The Ethernet bus module can connect up to 8 power controllers of type Thyro-A, type Thyro-AX 1A and type Thyro-S with a master. Several bus modules can be used on one system.
The electronics of the control device is supplied by a seperate connection with 230V~/110V~.
The connection is made at terminals X4.1 and X4.3. Terminals X4.1 and X4.2 along with X4.3 and X4.4 are internally bridged for alternative connection option.
Power supply and load:
Make sure that the load (IR-heater) is connected to the Terminal T1 and N.
The Controller Power supply 230V~/400V~ should be connected to the Terminal L1. On Terminal X1.1 connect N or the other middle phase. When connecting to a phase a 2A slow acting fuse is required, at N the connection can be made directly.
Terminals X1.1 and X1.2 are internally bridged.
Terminals X22.1...X22.4 are used for the communication to the bus module.
Make sure that the connection of the external 24V power supply is made at the terminals X11.1(+) and X11.2(-).Ground to X11.3.
Connecting the Power Controller to X1-X8 of the Bus Module:
Switch off the main Power Supply including the external 24V Power source.
Connect the interfaces X1 to X8 of the bus Module to the system interfaces of the Power controller.
Make sure a shielded four wire cable is connected at the terminals X22.1...X22.4 of the power controller to X1.1...X1.4 of the bus module.
Bus Module connection to the Master (PLC):
One of the Ethernet ports at Terminal X202 has to be connected to the PLC or to a switch.
To connect to Thyro-Ax module, A standard patch cable (straight) is required for direct connecting with a Thyro-Ax Module. For a connection via switch, a cross-over cable is required.
3.2.1 Bus module connecting terminals overview[edit | edit source]
With the touch display all the parameters could be changed. By pressing the icon Menu at the bottom of the display you will reach the parameter list.
Select a specific parameter by choosing it, another list will show up where changing the parameter values is possible.
By pressing at the upper part of the display. It will show over several screens the current Values.
The Thyro-Ax is equipped with a variety of functions, so it can be fitted to the desired application.
For optimal adaptation to different applications or varying electrical loads the appropriate operating mode can be selected by the User.
Following modes could be selected:
Full Wave Mode Takt
Phase Angle Firing Var (Only Thyro-AX 1A and 3A)
SST ramp in operating mode Takt
Quick Takt Mode Qtm (Only Thyro-AX 1A)
Switch Mode Switch
Select the Quick Takt Mode QTM operating mode, because of its high control dynamics.
The load monitoring is a function to identify a breakdown or wire break of one or more resistors connected in parallel series.
Therefore the values of load resistance characteristic have to be in the device.
Values Set:
Several ways to adjust the Load resistence (R_Max):
TeachIn function (preferred): the load characteristic will be measured automatically.
Preparations for the TeachIn:
Connect with the Thyro-Tool and adjust the monitoring and R auto wait like shown in the picture below.
Activate Rmin, Rmax, Ipeak max and Temperature unit max
The R auto wait is the measuring time for the TeachIn. Set to 120s. Within 120s the temperature is high enough for a stable resistor.
If a heater is not working anymore or has a wire break following message in Thyro-Tool AX Software and in PVSS will appear and the display screen will turn red.
Make sure the bridge is installed between the terminals X2.2 and X2.1. In case of missing connection the pulse inhabitation is activated, which means the current does not flow anymore.
By missing connection the touch display turns red and in the data logger "pulse on" is listed.
The Parameter Settings can be done either by the touch display or by using the Thyro-Tool-AX Software.
Use the Ethernet port to establish a connection between a PC and the Thyristor controller.
The parameters can be also transferred from one device to another of the same type by using a USB stick.
Write parameter from device to USB-stick:
Plug in a USB-stick.
A message will show up and asks to disable the Output--> pulse inhabitation will be activated (means no current flow).
Agree with OK, the display turns red.
Select write parameter to download file from Device--> USB-stick.
After parameter are downloaded, the message "DONE" will be shown.
Unplug the USB-stick, agree the message to activate the output with OK. Device will turn to normal operation again.
Read parameter from USB-stick to Device:
Plug in a USB-stick.
A message will show up and asks to disable the Output--> pulse inhabitation will be activated (means no current flow).
Agree with OK, the display turns red.
Select read parameter to download file from USB-stick--> Device.
Agree the message "Save to EEPROM" after downloading the parameter.
unplug the USB-stick, agree the message to activate the output with OK. Device will turn to normal operation again.
The supply voltage is not always displaying the value (e.g.400V) in PVSS but shows up after switching on the thyristor. That is related to the fact that
the Thyro-AX is measuring The voltage on the load side and then determined by the modulation of the supply voltage. Since the accuracy increases with increasing modulation of the line voltage, the supply voltage is not displayed at low power levels.
Set the rotary switch "Protocol" to 0 for profinet.
Set the rotary switch "Slots" to the number of Power controller (up to 8) which are connected to the bus module.
For changing the number of the used slots, the rotary switch must be turned first to 0 and then you have 2 sec. time to set a new number after leaving the position 0.
The Software Tyhro-Tool AX is for parameterization and visualization of connected devices of series Thyro-AX. You can use it for setting the parameter instead of the touch display.
By using the Software a remote maintenance is easier and we have the maximum control over the devices.
To Establish a connection to the device, a direct connection or a line connection to the machine Network is required.
If the controller shows "frequency tolerance exceeded" error and the heaters goes off due to that error, increasing the frequency tolerance range would be a solution.
5. Select the controller and type in the field Link the address of the frequency tolerance range parameter 0_0_75_0_3, change the correspondent value from default value 5 to e.g. 10 and send then save the new configuration to the controller
