OPERATION
Controller Display
The 5000 Controller default normal operation screen is shown in Figure 10. The first
three lines of the display are fully user programmable. Live moisture concentration
and system values such as cell temperature, pressure, and flow rate may be displayed.
The fourth line displays system messages and alarm/error information only. Refer to
Display Flags and Labels in Page 4-2 for more information on changing the format of
the controller display.
System Security and Passwords
The 5000 Controller has four system security levels, Levels 0 through 3. A password
must be entered before certain menus and system values can be accessed. Factory de-
fault passwords are listed later in this section, and may be removed from this manual
at the user's discretion. Note that higher levels passwords can access any lower level
function. With the exception of Level 3 security, default passwords can be altered or
eliminated by changing the software configuration. Refer to Page 4-3, Passwords for
more information on altering system security.
Level 0 Security (Operator Level)
No password is required for the following functions:
• Initiate an auto-calibration cycle with no span adjustment.
• View upper and lower levels for concentration alarm.
• View upper and lower range limits for 4 to 20 mA analog outputs 1 and 2.
• Manually select high or low range setting for analog output 1.
