Why does the switch trip on my SAJ Controller?
If the SAJ Controller switch trips, it could be due to an installed leakage switch or air switch overload, so replace the air switch (without leakage) or replace the air switch with a larger capacity. It could also be due to abnormal input power, so check input power and eliminate short circuit. If these steps don't work, look for technical support, as the internal instrument may have failed.
Why is the DI terminal failing on my SAJ Controller?
If the SAJ Controller DI terminal is failing, it may be due to incorrect parameter settings, so check and reset the F5 group parameters. It could also be due to an external fault, so reconnect the signal wire and clear external faults. If these steps don't work, look for technical support, as the control board may have failed.
What causes overload of buffer resistor in SAJ Controller?
If the SAJ Controller experiences overload of the buffer resistor, it is due to abnormal input voltage, so adjust input voltage to normal range.
What causes an output phase loss on a SAJ Controller?
If the SAJ Controller shows an output phase loss, it could be due to broken wires in the output cable, so check the wiring and installation.
Why my SAJ Controller pump cannot run?
If your SAJ Controller pump cannot run, it could be due to a lack of input power. Increase panel power or restart at enough light. The motor might have failed or is stuck, so replace the motor or check for mechanical fault. Also, make sure that the wiring of the motor is correct.
Why is my SAJ Controller showing over-current during acceleration?
If your SAJ Controller experiences an over-current during acceleration, it could be due to a few reasons. The acceleration might be too fast; in this case, try increasing the acceleration time. Alternatively, the input voltage might be too low, so check the input power supply and wiring. Finally, the controller itself might be under-rated, requiring a replacement with a higher-rated controller.
Why is the motor making a big noise with my SAJ Controller?
If you are experiencing a big noise from the motor connected to your SAJ Controller, the motor may have failed or is stuck, so replace the motor or check for mechanical faults. Also, the carrier frequency might be abnormal, so increase it properly.
What causes an input phase loss on a SAJ Controller?
If the SAJ Controller is showing an input phase loss, it is due to an abnormal input power source. Check the input power source and wiring.
Why is my SAJ Controller showing under voltage of DC bus?
If your SAJ Controller is showing an undervoltage of the DC bus, it is because of too-low input voltage. Check the input power supply or wiring.
What causes over-voltage during acceleration in SAJ Controller?
If the SAJ Controller shows an over-voltage during acceleration, it may be due to abnormal input voltage, so check input power. Another cause could be restarting the motor when instantaneous trip-off occurs; avoid prompt restart when trip-off.
