Password security

NOTE:
NOTE
3–40
Password security is an optional feature of the 339 which can be setup using the EnerVista
3 Series Setup software. The password system has been designed to facilitate a hierarchy
for centralized management. This is accomplished through a Master level access
password which can be used for resetting lower level access passwords and higher level
privileged operations. In cases where operational security is required as well as a central
administrative authority then the use of the password system is highly encouraged. The
feature robustness of this system requires it to be managed exclusively through the
EnerVista 3 Series Setup software. This section describes how to perform the initial setup.
For more details on the password security feature, refer to Chapter 6 - Password Security.
1. 339 devices shipped from the factory are initially set with security disabled. If the
password security feature is to be used, the user must first change the Master
Password from the initial Null setting, this can only be done over communications, not
from the front panel keypad. The new Master Password must be 8 to 10 characters in
length, and must have minimum 2 letters and 2 numbers. The letters are case
sensitive. Set Change Master Password to Yes to enable password security. After
entering a valid Master Password, enter the new Master Password again to confirm,
then select Change Password.
To disable password security, Set Change Master Password to Yes and then click Disable
Password.
2. Now that the Master Password has been programmed, enter it again to log in to the
Master Access level. The Master Level permits setup of the Remote and Local
Passwords. If the Master Password has been lost, contact the factory.
3. With Master Level access, the user may disable password security altogether, or
change the Master Password.
4. The Master Access level allows programming of the Remote Setpoint and Remote
Control passwords. These passwords are initially set to a Null value, and can only be
set or changed from a remote user over RS485 or Ethernet communications. Remote
Passwords must be 3 to 10 characters in length.
