14.5 MODE 2 – Digital switched enable / disable, external analogue 0-10Vdc speed or head control
Application:
Using an external 0-10Vdc signal to control the speed or head of the pump and a separate signal to
enable/disable the motor. Pump starts on low speed or head.
Sequence of Operation:
• Set 3 and Set 1 Open – Pump in Standby (VFD powered, motor is off, no flow), regardless of 0-10Vdc signal
• Set 3 and Set 1 Closed – increasing 0-10Vdc signal
- 0 to 0.5 V pump runs at min speed (25% of max speed) or min head (15% of max head)
NOTE: Min speed user adjustable to meet min flow requirements
- 0.5 to 10 V speed increases linearly to V
• Set 3 and Set 1 Closed – decreasing of 0-10Vdc signal
- 10 to 0.5 V speed decreases linearly to V
- 0.5 to 0 V pump runs at med speed (Standby when Set 3 and Set 1 open)
Summary:
• Enable / disable separate signal from 0-10Vdc
- Mode 1 – Pump starts and stops on medium speed (or head)
- Mode 2 – Pump starts and stops on low speed (or head), adjustable
• Enable / disable and 0-10Vdc external control the same signal
- Mode 1 – Pump starts and stops on minimum speed (or head)
