Password for Web User Interface Programming
Problem
Cause/Solution
I have lost the login password of the Web
user interface for the Administrator or User
account.
• Reset the password from the unit. The passwords for both
Administrator and User will be reset (® see 1.2 Reset
(Page 33) or 4.8.10 Reset & Restart (Page 180)).
For security reasons, it is recommended that the
passwords are set again immediately (® see
4.4.2 Administrator Password or 4.4.3 User
Password).
