What to do if the Advanced Energy Thyro-PX 3PX Controller has no LEDs lit?
- K
  karen22Aug 20, 2025
  If no LEDs are lit on the Advanced Energy Controller, it could be due to several reasons: * The customer-supplied power supply for the A70 control device might be missing. Verify 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. * Check that fuses F2 and F3 on the A1, A3, and A5 controller cards are not open. * Also, ensure that the semiconductor load fuses are not open. * For transformer loads, the phase angle of the first half-wave might need optimization. Start with a phase angle (phase angle 1) = 60 degrees and slowly increase it until the inrush current is minimized.

  If the red LIMIT LED is lit on the Advanced Energy Controller, it indicates that the unit is unable to supply enough power to match the setpoint due to a limiting condition. To resolve this: 1. Disable the output. 2. Verify that the limitation setting is correct. 3. Verify that the unit load and load connections are correct.

What to do if there is no load current in my Advanced Energy Controller?
- C
  Cameron WilliamsAug 26, 2025
  If there is no load current in the Advanced Energy Controller, ensure that 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. Also, confirm that the setpoint is available and active. You can check the total setpoint (effective total) using the display or software, or measure the setpoint on X52.2 and X52.5.

Why are the thyristors set to full scale on my Advanced Energy Thyro-PX 3PX?
- A
  Alex JacobsonAug 28, 2025
  Several factors can cause the thyristors to be set to full scale on the Advanced Energy Controller. Consider the following: * Check the control characteristic of the respective analog inputs. * The controller parameters Ti and Kp might be set too small. * Parameters Iemax, Uemax, and Pmax might be set too large, or the load current might 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. * 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.

- R
  Regina LopezAug 29, 2025
  To troubleshoot other malfunctions in the Advanced Energy Controller: * Evaluate the fault log entries with the Thyro-Touch display or the Thyro-Tool Pro PC 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.
