What to do if Keyboard without display after power on SAJ Controller?
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 PDS23-2SR75 Controller 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 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 Controller 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 PDS23-2SR75 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 PDS23-2SR75 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 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 PDS23-2SR75 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 Controller 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.
