Signal Output Options
VPWM voltage speed control is an optional function for this series. FG / RDH / RDL / LD outputs depend on the complete part number.
| Signal | Direction | Function | Description |
|---|---|---|---|
| VPWM | Control Input | DC voltage speed control | EC series speed is set by an external DC control voltage, commonly 0-5 V or 0-10 V. The control line must share ground with the fan supply negative; input range, wire colour, impedance and minimum speed follow the complete part-number approval sheet. |
| FG / TACH | Status Output | Reports speed as a pulse train | Typically an open-collector/open-drain output with an external 4.7–10 kΩ pull-up; usually 2 pulses per revolution, RPM = FG Hz × 60 ÷ 2. Pull up to the host logic supply, never directly to the fan supply. |
| RDH / RDL | Alarm Output | Locked-Rotor Alarm Rotation Detector / Locked-rotor Alarm | RD is a locked-rotor status output — it does not indicate reverse rotation. RDH goes high when the fan is locked or stopped; RDL goes low. Usually an open-collector output; start-up delay and actual levels follow the complete part-number approval sheet. |
| LD | Alarm Output | Life Detection Life / Low-Speed Detection | Detects speed decay or fan ageing: the output goes low when speed falls to roughly 70% of rated. LD is not the same function as the RD locked-rotor alarm and is available on selected models only. |
Signal notes:RDH and RDL are two output polarities of the same locked-rotor alarm; LD is life/low-speed detection. The three are not interchangeable, and wire colour must never be used to identify a function. VPWM describes the EC series DC voltage speed-control capability — the actual model, wire colours and control range follow the approval sheet.
Typical signal diagrams
FG / TACH
Tachometer Pulse Output
A continuous pulse train lets the host calculate speed. Usually an open-collector output; pulses per revolution, pull-up voltage and resistor must be confirmed per model.
VPWM
DC voltage speed control input
The external DC control voltage is applied to the VPWM lead and shares ground with the supply negative; speed rises from minimum to maximum with the control voltage. Wire colour and range follow the approval sheet.
LD
Life Detection life / low-speed detection output
The output goes low when speed falls to roughly 70% of rated, indicating performance decay; LD differs from the RD locked-rotor alarm.
RDH / RDL
Two output polarities of the locked-rotor alarm
RDH is high on lock; RDL is low on lock. They differ only in polarity and both indicate whether the fan is locked or stopped; start-up delay and electrical ratings follow the complete part-number approval sheet.
How to read these diagrams:These are MAX FLOW function concept diagrams, not fixed electrical parameters for every series. Before design, obtain the wire colours, ratings, pull-up conditions, output polarity and failure states for the complete part number.
