What to do about over-voltage at constant running speed with SAJ Controller?
If you are experiencing over-voltage at constant running speed with your SAJ Controller, install a proper input AC reactor, as the cause is an abnormal input voltage.
Why is my SAJ PDS23 Plus showing a motor overload?
A motor overload on your SAJ Controller can occur if the input voltage is too low, so check the input power supply or wiring. Alternatively, the controller may be under-rated for the motor; in this case, consider replacing it with a higher-rated controller.
How to fix an overheating SAJ PDS23 Plus?
If your SAJ Controller is overheating, there are several things you can check. First, refer to the over-current remedy, as an instantaneous over-current could be the cause. Ensure there is no output short circuit by re-wiring the output. Check the cooling fans; replace them if they've stopped or are damaged, and clear any obstructions in the ventilation channel. If the ambient temperature is too high, try to decrease it. Inspect and tighten any loose cables or terminals. If these steps don't resolve the issue, it may be due to an abnormal power circuit.
What to do if there's over-current during acceleration with my SAJ PDS23 Plus Controller?
If you're experiencing over-current during acceleration with your SAJ Controller, it could be due to a few reasons. The acceleration may be too fast, so try increasing the acceleration time. Also, check the input power supply or wiring, as the input voltage might be too low. If neither of these resolves the issue, the controller might be under-rated, and you should replace it with a higher-rated one.
Why am I getting over-current at constant running speed on my SAJ Controller?
If your SAJ Controller is showing over-current at a constant running speed, it could be due to a sudden change of load, so check the load. Another possibility is that the input voltage is too low, so check the input power supply or wiring. It could also be that the controller is under-rated, requiring a replacement with a higher-rated controller.
What causes over-current during deceleration in an SAJ PDS23 Plus?
Over-current during deceleration in your SAJ Controller can be caused by deceleration that is too fast; increase the deceleration time to resolve this. If the load is too heavy and has large inertia, add proper braking units. The controller may also be under-rated, so consider replacing it with a higher-rated controller.
What should I do if my SAJ PDS23 Plus shows a tank level fault before auto start?
If your SAJ solar controller displays a tank level fault before auto-start, it means the high-level limit has been reached. Wait until the water level comes below the low-level limit, and then the controller will start the pump again.
Why does the DC switch trip when I power on my SAJ controller?
If the DC switch trips when you power on your SAJ controller, there might be a short circuit. Check the internal circuit of the controller.
How do I fix a communication fault on my SAJ PDS23 Plus?
To address a communication fault on your SAJ Controller, verify that the baud rate setting is correct. Check communication devices and cables if there is a long-time communication interruption.
Why am I seeing an under voltage of DC bus error on my SAJ Controller?
If you're encountering an under voltage of DC bus error on your SAJ Controller, it's likely due to an input voltage that is too low. Check the input power supply or wiring to ensure it's within the correct range.
