If your Flotronic Water Pump isn't running, first, restore power to the main control unit and press the Reset button. If the problem persists, check the air supply to the pump. Also, the pump itself may have failed; in this case, strip and assess the pump in accordance with the pump IOM.
What to do if the Fault LED is flashing on my Flotronic Water Pump?
If the Fault LED is flashing on your Flotronic Water Pump, it could be due to several reasons. First, diaphragm failure might be the cause, so strip the pump and check for diaphragm failure or the presence of liquid in the air chamber. Second, check the sensor cable for damage and ensure sensors are plugged into the main control unit. For the sensors, you can perform a sensor check on page 10 to confirm their function. Finally, it could be a Main Control Unit fault. In this case, perform a full system check to establish a definite fault with the unit and not a legitimate liquid sensing.
How to troubleshoot a Flotronic One-Nut when the Power LED is off?
If the Power LED is not illuminated and your Flotronic Water Pump system isn't functioning, check the power supply lead for damage and confirm the unit is receiving power.
What to do if Flotronic Water Pump doesn't stop when fault LED is flashing?
If your Flotronic Water Pump doesn't stop when the fault LED is flashing, check the solenoid cable for damage and ensure the solenoid valve isn't faulty. Also, verify the solenoid valve complies with the requirements stated in the Technical section of this manual.

The Flotronic 'One-Nut' Pumps Diaphragm Leak Detection System is designed to monitor Flotronic Double Diaphragm pumps for diaphragm failure, which could lead to contamination of the pumped product, the pump's internal air control systems, or the surrounding area. The system aims to prevent such contamination by detecting leaks and stopping the pump's operation.
The leak detection system consists of two capacitive sensors and a main control unit. The sensors are mounted on the pump, one per air chamber, and continuously monitor the air chambers for the presence of foreign material other than air. These capacitive sensors detect changes in a self-generated capacitive field, allowing them to function correctly with most pumped substances, regardless of whether the media is conductive or transparent. A key feature of these sensors is their ability to sense through a protective PTFE housing, preventing direct contact with aggressive pumped media while still detecting leaks.
Upon sensing a diaphragm failure, the main control unit activates a customer-supplied solenoid valve in the pump's air supply line, stopping the pump. A flashing red LED on the main control unit indicates the fault. The system latches into an alarm condition until the failure is cleared and the unit is reset by pressing the front panel-mounted Reset button. If the pumped media is still contaminating the sensors, the unit cannot be reset until the fault is rectified. In the event of a power failure to the main unit, the pump defaults to an "off" state and remains stopped until power is restored and the Reset button is pressed. The main control unit also alarms and sets to a fail condition if the sensors are not connected or if they fail to operate within their normal parameters.
The system includes a volt-free relay connection that can be wired for either normally open or normally closed configurations upon an alarm state. This connection can be used to monitor the unit's state (running or fault) or to control other equipment dependent on the pump's status. To fully comply with the 3A standard, a solenoid valve must be connected to the main control unit to stop the pump upon detecting a failure. This solenoid valve should be fitted to the air pipe supplying the pump.
