1. Max Speed Reference
2. Wake-up Speed
3. Minimum/Sleep Speed
4. Terminal 53 Low Ref./Feedb. Value
5. Analog value corresponding to Sleep Speed
6. Analog value corresponding to Wake-up Speed
7. Terminal 53 High Ref./Feedb. Value
Note: if Sleep Mode is disabled, when the analog value is below Sleep Speed the pump will run at Sleep
Speed.
Example of settings for analog input 53 (4-20 mA):
Max Speed Reference = 50 (Hz)
Minimum/Sleep Speed = 20 (Hz)
Wake-up Speed = 25 (Hz)
Terminal 53 Low Ref./Feedb. Value = 0
Terminal 53 High Ref./Feedb. Value = 50
The analog value corresponding to Sleep Speed is:
Signal range*(Min Speed/Max Speed) + zeropoint 16 * (20 / 50) + 4 = 10,4 (mA)
The analog value corresponding to Wake-up Speed is:
Signal range*(Wake-up Speed/Max Speed) + zeropoint 16 * (25 / 50) + 4 = 12 (mA)
