7 Programming

You can 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 authori-

sation continues until the user closes the menu.

To enter the access code, use the B

BACK

and O

buttons to

select a digit, and the

Ⴃ

and

Ⴍ

buttons to change the value.

When all four digits match your access code, press O

. The

LCP will display an acknowledgement message before

continuing.

To change the access code, use par. 15-1.

Enter Access Code

SUPERVISOR

NOTE

The protection simulation and output simulation are also

protected by the security access code. The co

unters and

thermal model reset can be viewed without entering an

access code, but an access code must b

e entered in order to

reset.

The default access code is 0000.

You can lock the menus to prevent users from altering

parameter settings. The adjustment lock can be set to allow

Read & Write, Read Only or No Access using Par. 15-2.

If a user attempts to change a parameter value or access the

Main Menu when the adjustment lock is active, an error

message is displayed:

Access Denied

Adj Lock is On
