Sequence of Operation:
• Set 3 and Set 1 Open – Pump in Standby (VFD powered, motor is o, no ow), regardless of PWM signal
• Set 3 and Set 1 Closed – increasing PWM signal
- 0 to 12% pump standby
- 12% to 15% pump runs at min speed (20% of max speed) or min head (10% of max head)
NOTE: Min speed user adjustable to meet min ow requirements at 3 V)
- 15% to 95% speed (or head) increases linearly with % change
• 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 3 – PWM Solar
