4.3. Browser Passwords & Lockout
After 5 unsuccessful attempts to log on, the controller locks out Ethernet and Keypad access.
Locked out users will see an
Alarmed
status message in place of
Password Incorrect
.
Browser & modem resets at 7:00AM or when AC power OFF/ON.
Therefore, the maximum lockout time is 24 hours and the minimum is less than a minute.
This feature blocks scripting attacks on controllers and cannot be disabled.
There is no limit on the number of keypad password attempts.
Changing all passwords from their default values is strongly recommended.
Passwords can be reset to the factory default by logging on as the
Reset Pswrds
user and entering a factory
provided password.
Refer to Browser Manual for more information.
4.4. LCD Keypad Passwords
Passwords are defaulted OFF for keypad users.
The
System/Password
menu item does not display unless
System/Configure
has turned passwords ON.
Once passwords are turned ON, only the administrator can access
System/Configure
to turn Passwords OFF
If passwords are ON, you are prompted with the required password level;
Admin / Configure /
Operate
when
you attempt to execute a command which reconfigures the controller.
Passwords are not required to view the current status.

Keypad-LCD access cannot change User Type or ID.
NOTE:
If you are going to use keypad passwords, your first action should be to change the admin and all other
passwords, since leaving any password at its default value, bypasses password protection. After changing all
the passwords, turn keypad passwords ON using the keypad or the browser interface.
