Protected Parameter Mode - Omega CN63100 Series User Manual

PROTECTED PARAMETER MODE

The Protected Parameter Mode is accessed by pressing the P button from
the Normal Display Mode with Program Disable active. While in this mode,
the parameters can be accessed by pressing the P button. The temperature or
scaled process value (after initial setup) will be displayed in the main (top)
display. The parameter display will appear with the corresponding range and
units in the secondary (bottom) display. Each of these parameters can be
independently locked out from appearing or from being modified through the
Lockout Parameter 3-LC.
To modify values, use the Up or Down arrows while the parameter is
displayed. If locked, the parameter will not show in the Normal Display
Mode, but can be changed in the Protected Parameter Mode. The controller
responds to the new values immediately, however, the change is not
committed to non-volatile memory until the controller is returned to the
Normal Display Mode. If power loss occurred before returning to the Normal
Display Mode, the new values must be entered again.
To gain access to the Unprotected Parameter Mode (with User Input
inactive or not programmed for PLOC), continue to CodE and press the arrow
buttons until the value equals the Code as entered in parameter lockouts.
When an incorrect code value is entered, or when the D button is pressed,
"End" will momentarily appear and the controller will return to the Normal
Display Mode.
