Fluid-o-Tech FEE2EWR1 TMFE2 Variable Speed Controller for TMFR Rotary Vane Pump-Motor Units
The Fluid-o-Tech FEE2EWR1 is the 230VAC TMFE2 series driver module designed specifically to power and control TMFR and TSFR series rotary vane pump-motor units. This compact yet capable controller serves as the essential brain behind the TMFR's brushless electromagnetic motor, delivering smooth, reliable speed regulation across a wide operating range. Running on a single-phase 230VAC supply (±10%) at 50/60 Hz, it outputs a trapezoidal three-phase signal to the pump motor, enabling variable speed operation from 500 to 3,500 RPM. Without this controller, the TMFR pump-motor unit simply cannot operate — it is required in all configurations, whether or not variable speed control is actively being used.
What makes the FEE2EWR1 particularly versatile is its support for six distinct operating modes, giving engineers and system integrators the flexibility to match the controller's behavior precisely to the demands of their application. Control options include preset speed via DIP switch, analog voltage input (0–5V), analog current input, and opto-coupled digital on/off — with combinations available to suit complex automated systems. Built-in protections cover over-voltage, over-current, rotor blockage, and hardware faults, with both auto-resettable and permanent fault signals. CE certified and compliant with relevant EMC and safety standards, the FEE2EWR1 is a purpose-built, high-quality industrial component backed by Fluid-o-Tech's global engineering reputation.

Frequently Asked Questions
Q: Is the FEE2EWR1 controller required even when I'm not using variable speed control on my TMFR pump?
Yes. The FEE2EWR1 — or its equivalent TMFE2 series controller — must be present and connected at all times for the TMFR or TSFR pump-motor unit to function at all. The controller is integral to motor operation regardless of whether speed is being varied or held at a fixed preset.
Q: How long should I wait before servicing the FEE2EWR1 after disconnecting power?
A minimum of three (3) minutes must elapse after disconnecting the power supply before performing any service on the unit. Internal capacitors retain dangerously high voltage even after power is removed, and this waiting period is a mandatory safety requirement.
Q: Can the FEE2EWR1 be driven with a control signal voltage higher than 5VDC, such as 12V or 24V?
Yes, but a series resistor must be added to the control connection when using signal voltages above 5VDC. Consult the TMFE2 instruction manual for the appropriate resistor value based on the voltage being applied to ensure proper signal conditioning and to avoid damaging the controller input circuit.
Q: What should I do if the TMFR pump is expected to go through many on/off power cycles per day?
Operation with frequent on/off power cycling directly to the main supply is not recommended because the NTC inrush current limiter becomes less effective when cycled rapidly (it requires a cool-down off-time of greater than 100 seconds between cycles). For frequent on/off control, use the opto-coupled digital on/off input rather than switching mains power to the controller.
Q: Can I use a third-party replacement controller module instead of the genuine Fluid-o-Tech FEE2EWR1?
Fluid-o-Tech explicitly states that repairs and replacements must use genuine Fluid-o-Tech spare parts. Using unauthorized parts or third-party controllers can void UL approvals, compromise Safety Integrated functions, risk personal injury, and cause property damage. Always use the genuine FEE2EWR1 to maintain compliance and warranty coverage.
