8 Commissioning/Shutdown
Ensure that the following requirements are met prior to commissioning:
▪ The pump has been vented and primed with the fluid to be handled.
▪ Flow through the pump is in the design direction specified in order to avoid
generator operation of the frequency inverter.
▪ A sudden start-up of the motor or pump set does not result in personal injury or
damage to machinery.
▪ No capacitive loads, for example for reactive current compensation, are
connected to the outputs of the device.
▪ The mains voltage is in the range approved for the frequency inverter.
▪ The frequency inverter has been properly connected to the power supply
(ðSection7.4,Page33) .
▪ All enable and start commands that can start the frequency inverter are
deactivated (refer to digital inputs, DI-EN Digital Enable Input and DI1 System
Start).
▪ No voltage is applied to the power supply module of the frequency inverter.
▪ The frequency inverter and/or the pump set must not be loaded above the
permissible nominal power.
▪ The flow rate estimation function activated at the factory is required for many
pump-related functions such as starting and stopping pumps. It is therefore
recommended that the flow rate estimation function be left on.
8.1 Commissioning wizard
The commissioning wizard guides you through the most important commissioning
parameters such as the motor parameters and parameters for basic applications
including open-loop control mode, discharge pressure control, and differential
pressure control.
After the frequency inverter has been switched on for the first time, the
commissioning staff sets the language to be used on the control panel.
The system then prompts the operator to start the commissioning wizard. The
commissioning wizard guides the operator through the following settings:
▪ Setting of date and time
▪ Entry of motor data
▪ Selection of the application:
– Open-loop control mode
– Discharge pressure control
– Differential pressure control
The individual parameters can then be set for the individual applications. Press the
OK key to confirm the entry and the ESC key to cancel it.
Commissioning wizard
The commissioning wizard can be restarted by the Commissioning Wizard parameter
(3-1-5). In a first step, the default factory settings are reloaded. All the relevant
application parameters must be configured again using the commissioning wizard.
Multiple pump
configuration
After a pump system is started for the first time, a detection routine is started to
determine whether the system is a multiple pump system. For specific parameters
such as "Role in Multiple Pump System", the relevant data must be entered
separately at each frequency inverter in the system. The commissioning wizard is
therefore called up at every frequency inverter when the system is started for the
first time.
If a multiple pump system is identified, the user is prompted to specify the
corresponding parameters after having entered the motor data.
If the commissioning wizard is later started again via parameter 3-1-5, it is only run at
the frequency inverter where the start was initiated.
