Sequence of Operation:
• Set 3 and Set 1 Open – Pump in Standby (VFD powered, motor is off, no flow), regardless of PWM signal
• Set 3 and Set 1 Closed – increasing PWM signal
- 0 to 5% pump at max speed or head
- 5 to 85% speed decreased linearly with % change
- 85% to 93% pump on standby
NOTE: Min speed user adjustable to meet min flow requirements at 3 V)
- 93% to 0% pump on standby
• Set 3 and Set 1 Closed – decreasing PWM signal
- 95% to 15% - speed decreases linearly with % change
- 15% to 7% - pump runs on min speed
- 7% to 0% - pump standby
MODE 4 – PWM Heating
SET2 (PWMout) Status
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
