What does it mean if the green ON/ READY LED is not lit on the Advanced Energy Thyro-PX Controller?
If the green ON/ READY LED is not lit on the Advanced Energy Controller, the auxiliary 230 VAC or 24 VDC supply is faulty.
What to do if my Advanced Energy Controller has no load current?
If your Advanced Energy Controller shows no load current, verify the following: * The supply voltage of the A70 control device is within the range of 90 VAC to 265 VAC, or X3.1 and X3.2 are at 24 VDC. * The setpoint is available and active. Check the total setpoint (effective total) using the display or software, or measure the setpoint on X52.2 and X52.5. * Parameters of the control characteristic of the respective analog input are correct. * For 1PX and 2PX units, verify that the reference phase is connected. Also, check if parameters Iemax, Uemax, and Pmax are set too small, or if controller parameters Ti or Kp are set too large. For type 1PX, check if the load is broken or disconnected.
Why are no LEDs lit on my Advanced Energy Thyro-PX?
If no LEDs are lit on your Advanced Energy Controller, it could be due to several reasons. First, check for a missing customer-supplied power supply for the A70 control device. Then, ensure that the voltage at terminal X1.1 and X1.2 of the A70 control device is within the range of 90 VAC to 265 VAC, or that X3.1 and X3.2 are at 24 VDC. Also, verify that fuses F2 and F3 on the A1, A3, and A5 controller cards are not open and that the semiconductor load fuses are not open. For transformer loads, the phase angle of the first half-wave might need to be optimized. Begin with a phase angle (phase angle 1) = 60 degrees, and slowly increase until the inrush current is minimized. Check for missing power supply.
What causes the thyristors to be set to full scale on my Advanced Energy Thyro-PX Controller?
If the thyristors on your Advanced Energy Controller are set to full scale, check the control characteristic of the respective analog inputs. Also, controller parameters Ti and Kp might be set too small, or parameters Iemax, Uemax, and Pmax may be set too large, or the load current may be too small. If no load is connected, the voltage will be higher than 0 V. A load must be connected to troubleshoot this condition. Additionally, check the thyristor resistance between L1 and T1, L2 and T2, L3 and T3. If the resistance is greater than 100 ?, the thyristor is not damaged.
How to troubleshoot other malfunctions in Advanced Energy Thyro-PX?
To troubleshoot other malfunctions in your Advanced Energy Controller: * Evaluate the fault log entries using the Thyro?Touch display or the Thyro-Tool Pro software. * Check the parameters. * Check the wiring of the unit. * Check the number of controlled phases (parameters). * Eliminate the fault indicated by the fault relay. * Visually verify correct operation by replacing the loads with appropriately rated incandescent lamps.
