Then three levels of flow are required for the self-learning of three parameters:
Flow
NORMAL FLOW
MINIMUM FLOW
ZERO FLOW
STARTING
...WIZARD
ATTENTION: if the number
of pumps is 2 or 3
unit), this parameter is also
required:
W = inverter address
- First set the MASTER inverter
with the value W = MS
- Then leave the MASTER
inverter OFF (out of service)
- Then set the SLAVE1 inverter
with the value W = S1
- Then leave the SLAVE1
inverter OFF (out of service)
- Then set the SLAVE2 inverter
with the value W = S2
- Then put into service the
MASTER and SLAVE1 inverters
and the unit will operate
automatically.
Self-learning of the parameter
Correct rotation direction of the motor (models M/T)
Shutdown frequency
