7 Programming
It is possible to access the programming menus at any
time, including while the soft starter is running. All
changes take effect immediately.
7.1 Access Control
Critical parameters (parameter group 15 and higher) are
protected by a four-digit security access code, preventing
unauthorised users from viewing or modifying parameter
settings.
When a user attempts to enter a restricted parameter
group, the LCP prompts for an access code. The access
code is requested once for the programming session, and
authorisation continues until the user closes the menu.
To enter the access code, press [Back] and [OK] to select a
digit, and [
▲
] and [
▼
] to change the value. When all four
digits match the access code, press [OK]. The LCP will
display an acknowledgement message before continuing.
To change the access code, use
15-1 Access Code
.

NOTE
The protection simulation and output simulation are also
protected by the security access code. The counters and
thermal model reset can be viewed without entering an
access code, but an access code must be entered in order
to reset.
The default access code is 0000.
