PWM OUTPUT

PWM output signals flow and error information from the pump according to the bottom table.
PWM‐out
0 % PWM output interface in short circuit
2.5 % Pump in standby and ready
5 % Normal operation, no flow
5..75 % Normal operation, flow indication
75 % Normal operation, maximum nominal flow
80 % Error is present, performance might be reduced
85 % Error is present, pump is still functional, but might be stopped
90 % Error is present, pump is stopped
95 % Error is present, pump is stopped, permanent failure, will not restart
100% PWM output interface is open circuit or pump is not powered
