5.8 Access Codes
There are three levels of access code protection. If the Master password is used in the Webmaster,
then any set point can be changed. If the Calibration Level password is used, then sensor
calibrations will be allowed, but other changes will not. If the Read Only password is used the user
will be able to look at any menu, but will not be allowed to make any changes.
In order to change the access code for each level of access, use the Next key to move the cursor to
the space next to Present, and use the Arrow keys to make the characters match the present access
code (you have to know the present code to change it). Press the Enter key to move the cursor next
to New, then use the Arrow keys to make the characters match your new access code and press
Enter.
The default user name is "webmaster" and the default passwords are "2001" for full access, "2002"
for calibration only, and "2003" for read only. These defaults can and should be changed to assure
security.
6.0 OPERATION – Using PC
These units control continuously as long as power is applied. This section describes how to set up
the controller utilizing a PC. See Section # for instructions utilizing the controller keypad and
display.
When you first access the controller, the Conductivity Input page will be displayed in the main
frame of the browser, and the Name of the controller and Alarm Status will be displayed in the top
frame. Links to each main menu page are located along the left side of the screen.
The menus are organized by inputs and outputs. Each input has menus for calibration, selecting
units of measure, etc. as required. Each output has menus for defining the set points, maximum on-
time, method of control, etc.
Keep in mind when the controller is powered, it will be responding to default set points. As set
points are changed, the controller will start using the new set points immediately. If it is
undesirable for the controller to activate valves and pumps during the set up process, either
disconnect them, or go to the “Hand-Off-Auto” menu for each output and force them “Off”..
