5.
Initial setup of the Local Setpoint and Local Control passwords requires the Master
Access level. If Overwrite Local Passwords is set to YES, Local passwords can be
changed remotely only (over RS485 or Ethernet). If Overwrite Local Passwords is set to
NO, Local passwords can be changed locally only (over USB or keypad). If changing
Local Passwords is permitted locally, the keypad user can only change the Local
Passwords if they have been changed from the initial NULL value to a valid one. Local
Passwords must be 3 to 10 characters in length.
6.
If any Remote password has never been set, that level will not be attainable except
when logged in as the Master Level. The same logic applies to the Local passwords.
7.
When passwords have been set, the user will be prompted to enter the appropriate
password depending on the interface being used (remote or local), and the nature of
the change being made (setpoint or control). If the correct password is entered, the
user is now logged into that access level over that interface only. The access level
turns off after a period of 5 minutes of inactivity, if control power is cycled, or if the
user enters an incorrect password.
