Static Sensor Calibration
Static calibration is performed to reset or restore sensor calibration values after a
hardware, software or factory configuration change. The previous dynamic cali-
bration results are shown on the Static Sensor Calibration screen to allow the
user to re-enter the values manually or perform a Restore operation to reset the
minimum and maximum range values for the previous calibration results.
Sensors should only be calibrated by qualified personnel and always against
devices known to be accurate. Refer to the information for the Calibrate Sensors
screen in the Additional Menus Operating Procedures section of this manual.
Password Control
The CCS system manager will assign user numbers, passwords, screen read and
write access levels and screen access requirements for all users. A user is defined as
an individual or group of individuals who will be using the system. Each user of the
CCS can be assigned a numeric password to define their operating privileges. The
system manager's password will initially be assigned by M&M technicians upon sys-
tem configuration and may be changed by the system manager if desired. All other
users will be assigned a six digit password, which has an associated read and write
access level. A user must enter the numeric password to log onto the system to
obtain access beyond the basic system default access levels. Once a user is finished
performing the task required, he may then logoff manually. If the logoff option is not
selected, logoff will occur automatically after a 10 minute period of no keypad activity.
Adding/Deleting Users
The system manager is able to add or delete users from the CCS by accessing
the Add Delete User screen. A user is added by defining a password, read
access level and write access level. The higher the access level the more privi-
leges the individual will have on the system. Access levels will range from 0 to 9,
with the system manager being assigned 9 for full access. The read and write
features will each have their own access level with the left number being the read
access level and the right number being the write access level. The read access
level defines the access level at which a user may view a screen. The write
access level defines the access level at which a user may change data on a
screen. When a user is deleted this information is removed from the list. The
maximum number of users is 10. When the system is set to Factory Configura-
tion, User 01 is given a password of 999999 with full access. This should be
changed after the password system is setup.
Screen Access Levels
The system manager can assign read and write access levels to groups of
screens on the CCS by choosing the Screen Access Level menu selection. The
specific screens available for protection will vary depending on the system config-
uration. Some examples of screens which might be considered for limited access
are control, setpoint, calibration and initialization screens. Access for screens
such as set date and time and set log rate may be less restricted.
