Local access protection and user account administration
8.23.1
General advice on using PINs
The 3RW55 and 3RW55 Failsafe soft starters have 2 functions with a PIN each for protecting
against unauthorized access:
• Local access protection (Page 237)
• User account administration (Page 240) (user login and log off (Page 242))
You have the option of combining both versions.
Pins for local access protection and user account administration
Note that each function uses a separate PIN:
• HMI PIN for local access protection
• HMI User PIN for user accounts
Combination of local access protection and user account administration
When using local access protection and user account administration, note the sequence of PIN
entry on the 3RW5 HMI High Feature. Enter the HMI PIN first and then the HMI User PIN in order
to unlock locked menus.
If the HMI PIN and the HMI User PIN are identical, there is no need to enter the HMI User PIN on
the 3RW5 HMI High Feature.
8.23.2
Local access protection (PIN)
Operating principle
With the PIN, you can protect the 3RW5 HMI High Feature from unauthorized access. The menus
of the 3RW5 HMI High Feature can still be viewed with local access protection activated. It is not
possible to issue a control command or to set a parameter. If you issue a control command or
change a parameter when local access protection is enabled, you will automatically receive an
entry prompt for the current PIN beforehand.
The PIN remains even after the power supply has been interrupted. You can reset the local access
protection to the factory setting with the master RESET key on the rear of the 3RW5 HMI High
Feature (Page 280). Protect the master RESET key from unauthorized access.
Setting on the 3RW5 HMI High Feature
• Menu: "Security > Local access protection"
