Pro Series Common Questions

A-LS:

Q: What does the A-LS alarm code mean on my Pro Series System?
A: If your pump is displaying an A-LS alarm code, this means that the weak light alarm has been triggered. This occurs when the solar input wattage is too low.

Q: Why would the solar input wattage be too low?
A: The weak light alarm indicates that the solar input wattage is too low for the pump to operate properly. This can be caused by shading or obstructions blocking sunlight from reaching the panels, or there may be a loose connection.

Q: How can I resolve the weak light alarm?
A: To resolve the weak light alarm, first check your solar panels for any shade or obstructions that may be blocking sunlight. Next, check to ensure that all connections between the pump and solar panels are secure and properly connected. Adding additional solar panels may also increase the wattage input and resolve the issue.

A-LL:

Q: What does the A-LL alarm code mean on my Pro Series System?
A: If your Pro Series system is displaying an A-LL alarm, this means that the underload alarm has been triggered. This alarm indicates that the water pumping source, such as a well or stock tank, is low or empty.

Q: How is the underload alarm detected?
A: The underload alarm is detected after 60 seconds of low water flow or no water flow. The pump will then enter a "rest" mode for 120 seconds (2 mins) before attempting to pump again.

Q: How can I resolve the underload alarm?
A: To resolve the underload alarm, check your water well or stock tank to ensure that it is not low on water. If the water source is empty, wait for at least 120 seconds for the pump to attempt to pump again. Once the water source is refilled, the pump should operate normally. If the underload alarm continues to occur, contact our support line at [phone].

A-tF:

Q: What does the A-tF alarm code mean on my Pro Series System?
A: If your system is displaying an A-tF alarm, this means that your well or stock tank is full.

Q: How is the tank full alarm detected?
A: The hooked up tank full sensor has been tripped, indicating that the tank is full.

Q: How can I resolve the tank full alarm?
A: The water in the tank or well needs to be depleted a bit for the float switch to return to the off position.

Q: What should be done if the tank full alarm continues even when the water level is low?
A: If the tank full alarm continues even when the water level is low, perform test 9 on page 46 of your manual. Reach out to us at [phone] or create a ticket here.

SPO:

Q: What is the SPO fault code on my Pro Series system?
A: The SPO fault code refers to an "output phase loss" fault.

Q: What does the output phase loss fault indicate?

A: The output phase loss fault in a Pro Series system indicates that there is a loss of one or more of the three output phases from the pump. This can be due to a damaged wire or a splice issue.

Q: How can the output phase loss fault be resolved?

A: To resolve the output phase loss fault, the pump wires should be checked for any splice issues or wire damage. The wire resistances should also be checked. Additionally, the wiring to the controller should be inspected to ensure proper connections. Please see pgs. 27-31 in your Pro Series user manual for wiring and connections of the Pro controller. To order an additional splice kit, give us a call or text at [phone], or create a ticket here.
