Normal Display Mode; Front Panel Program Disable - Omega CN63100 Series User Manual

NORMAL DISPLAY MODE

In the Normal Display Mode, the temperature or scaled process value is
displayed in the main (top) display. By successively pressing the D button,
the parameters listed below can be viewed 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. If all four displays
are locked out, the display blanks after pressing the D button. To gain access
to the next modes, press the P button from any parameter.
To modify values in % Output Power (for Manual Control) or Setpoint, use
the Up or Down arrows while the parameter is displayed and not locked. If
locked, these parameters can be changed in the Protected Parameter Mode. The
controller responds to the new values immediately, however, the change is not
committed to permanent memory until 10 seconds after the last key press.
