What to do if Keyboard without display after power on SAJ PDS23-4T004?
To solve the keyboard without display after power on problem: * Use a multimeter to measure the input voltage of the controller; check the voltage is normal. * Check if the machine has a burning smell; if there is a burning smell, please contact the agent to replace the controller.
Why does my SAJ PDS23-4T004 show an E001 IGBT module fault?
An IGBT module fault (E001) in your SAJ Controller can occur due to several reasons. It may be caused by: * Too short acceleration time: Increase acceleration time. * Damaged IGBT module: Ask for support. * Malfunction caused by interference: Inspect external equipment and eliminate interference. * Improperly grounding: Check grounding wire.
What to do if SAJ PDS23-4T004 Controller displays E002 over-current during acceleration?
If your SAJ Controller shows an E002 error (Over-current during acceleration), it could be due to: * Too fast acceleration: Increase acceleration time. * Too low input voltage: Check the input power supply or wiring. * Lower-rating controller: Replace with higher-rating controller.
Why does my SAJ PDS23-4T004 show E004 over-current at constant running speed?
If your SAJ Controller displays error E004, indicating over-current at constant running speed, there are several potential causes: * Sudden change of load: Check the load. * Too low input voltage: Check the input power supply or wiring. * Lower-rating controller: Replace with higher-rating controller.
What causes E003 over-current during deceleration in my SAJ Controller?
The E003 error on your SAJ Controller, indicating over-current during deceleration, may be caused by: * Too-fast deceleration: Increase deceleration time. * Too-heavy and large-inertia load: Add proper braking units. * Lower-rating controller: Replace with higher-rating controller.
What to do if DC switch trip when power on SAJ Controller?
To solve the DC switch trip when power on problem: * A multimeter can be used to check the internal circuit of the controller, if there is a short circuit, the machine has been damaged. * Check if the machine has a burning smell; if there is a burning smell, please contact the agent to replace the controller.
What does E020 well level fault mean on my SAJ Controller?
If your SAJ Controller displays the E020 error, indicating a Well Level Fault, it's likely caused by: * Dry well or slow water recovery: Wait for water to recover or reinstall the pump.
What does E021 tank level fault before auto start mean on my SAJ PDS23-4T004 Controller?
If your SAJ Controller displays error E021, indicating a Tank Level Fault before auto start, it means: * High level limit is reached: Wait until water level comes below the low level limit, and then the PDS23 Solar controller will start the pump again.
What causes the E007 over-voltage at constant running speed error on my SAJ PDS23-4T004 Controller?
If you're seeing an E007 error on your SAJ Controller, which indicates over-voltage at constant running speed, it's likely caused by: * Abnormal input voltage: Install proper input AC reactor.
What to do if SAJ PDS23-4T004 displays E010 controller overload?
If your SAJ Controller is showing an E010 error (Controller overload), it may be due to: * Too fast acceleration: Increase acceleration time. * Avoid prompt restart when trip-off.
