Mode 3 and 4 is used for PWM control and feedback according to IEC 60469-1. The difference between these
two modes is in response to PWM-in signal. Mode 3 stops the pump when signal is missing or at 0 % while Mode
4 applies full power.
Terminal
designation
SET1 / RUN
PWM-in (PWM input)
Signal frequency: 100 Hz – 10000 Hz (1000 Hz nominal)
Signal load: 5 mA (4 – 6 mA, internally limited)
Signal amplitude: 3.3 – 24 V (threshold at approx. 3V)
COM / 0V
Common ground for signals
SET2 / MAX
PWM-out (PWM output)
Signal frequency: 75 Hz (±1 Hz)
Signal drive: Open drain, (100 ohm, 20 mA internal current limit)
Signal amplitude: 0 – 24 V
Signal polarity: Active high (0% - pulled to COM, 100% -open)
SET3 / FB
FB (10.5 V) output, can be used to supply SET1 and SET2 bias.
