REM620 Application Manual

Four user categories have been predefined for the LHMI and the WHMI, each with different rights and default passwords.

The default passwords in the protection relay delivered from the factory can be changed with Administrator user rights.

If the relay-specific Administrator password is forgotten, ABB can provide a one-time reliable key to access the protection relay. For support, contact ABB. The recovery of the Administrator password takes a few days.

Note: User authorization is disabled by default for LHMI but WHMI always uses authorization.
