Eaton QD5 User Manual

Security system
The security (password) system implemented on the CL-7
control is structured into four levels. This permits selective
access to the various parameters as dictated by the active
security level. Most function codes may be read (accessed)
at the View level, the base (unsecured) level. The security
level required to change or reset each parameter is listed
in Table7. The security access codes for levels 1, 2, and
3 have been programmed into the control at the factory.
These codes may be changed by the user according to
Table7. A secure password may consist of any combination
of letters, numbers, and special characters which include
the following requirements:

A minimum of five and maximum of 10 non-blank
characters.

A minimum of 5 letters

At least one upper case letter.

At least one special character (#, /, ? or !)

A letter in the first and last position.
Access into the system is accomplished by entering the
appropriate security code at FC 99.The user has the option
of overriding (inhibiting) one or more levels of security by
choosing the appropriate Security Override Code at FC 92.
Choices at FC 92 are View (no override), override Operate
level, override Modify and Operate levels, and override the
Operate, Modify, and Admin levels.
The values of the three security codes, FC 96, FC 97, and
FC 98, may be read only at the Admin level.
IMPORTANT
If the Admin security password is changed and
forgotten, it cannot be retrieved. This is to meet
international security guidelines which prohibit back-
door access to security passwords. In order to reset a
lost Admin password, the control must be returned to
the factory for reprogramming.
Remote security override
The remote security override feature allows for a temporary
override of control security through SCADA. This can be
used in cases where local operators are not provided with
passwords, but are required to make local changes using
the HMI.
Two function code settings configure and enable the feature
either through HMI or SCADA, but the feature can only be
activated by sending an analog value (Operate=1, Modify=2,
Admin=3) through SCADA to override the present security
level to the level specified. The remote override timer is set
at FC 199 to specify the length of the override in hours and
the feature is enables at FC 199.
Once the override is activated, it will continue for the
duration specified by the remote override timer and
then revert back to the previous security level. The timer
information is stored in non-volatile memory enabling the
override to continue after a power cycle unless the timer
has expired while power was off. If the timer is changed
when the override is in place, the timeout period will restart.
If the user enters a valid password from the front panel
while the remote security override is enabled, the control
will use the entered password and the remote security
override feature will be disabled.
