computer asks for the values.
The data available are:
•
Speed adjust
•
Pump/controller operating condition
•
Cycle time
•
Pump life
•
Pump temperature
•
Pump current
•
Pump voltage
•
Controller output frequency
•
Cycle number
•
R1 condition
•
R2 condition
•
Life time and cycle # zeroing
•
Configuration parameter readings
•
