Parameter settings can only be made at the service or factory access level.
ü The system is operational.
ü BoosterControl Advanced has been connected correctly.
ü Date and time have been set. (ðSection8.3.2,Page34)
1. Log in to BoosterControl Advanced at service or factory access level.
(ðSection6.6,Page31)
2. Set the parameters for the suction side. (ðSection8.5.1,Page45)
3. Set the frequency inverter parameters. (ðSection8.4.6,Page44)
4. Note dry running protection settings. (ðSection8.5.1,Page45)
5. Set the following parameters:
