18.2.2 - Check the starter configuration
The starter configuration is set at the factory. It can be
checked and modified on the starter interface using the
four navigation keys:
OK To select the menu, modify the value or register the parameters.
▲▼ To navigate in the menu or modify the values.
ESC To exit the current menu and pass to the next higher menu.
The control procedure is described below with the default
parameter settings from the factory.
BEFORE ANY INTERVENTION: Authorise and lock
access to the advanced parameters:
RW44/MENU/SAFETY
Enter user code 1000 or 1001
Selecting code 1000 gives access to the modification and
reading of all parameters. Selecting code 1001 gives limited
access to the modification and reading of the parameters.

Notes about the control values
• The parameter for the start-up current limitation can
be slightly adjusted, if required: refer to chapter 19.2.
• The starter is equipped with motor protection functions
that are not used: motor protection is controlled by
the PIC control. The starter parameter controls are
adjusted to ensure that the PIC control has priority
for the motor protection.
18.3.1 - Parameter setting
The standard machine parameter setting applies. For the
list of all parameters and their default values please refer
to the PIC III Controls IOM.
18.3.2 - Function test (quick test)
The standard machine tests apply.
The verification procedure for the standard machine must
be used. If the phases are reversed it is possible that the
starter detects the fault before the PIC control. In this case
an alarm indicating a rotation fault will appear on the
starter and not on the PIC control. The order of the phases
connected to the starter needs to be reversed.
