FRONT PANEL KEYS
The F1 key is pressed to exit (or escape) directly to the start of the
Display Loop. While in the Display Loop, the F1 key can be pressed to
activate its programmed function.
The Loop key is pressed to advance to the next parameter, to activate
a changed selection/value, and when held for three seconds, enter the
Hidden Loop.
The Arrow keys are used to scroll through parameter selections/
values and in the Configuration Loop they are used to scroll to the
appropriate Parameter Module.

DISPLAY LOOP
Note: Setpoint and Output Power are the only parameters visible in the Display Loop with Factory Settings. The remaining parameters can
be selected for the Display Loop within Module 3.
Parameter availability is model and programming dependent.
DISPLAY LOOP
At power up, all display segments light, and then the programmed input type
and the controller’s software version will flash. Then the Temperature/Process
Value is shown in the top display, and the Setpoint Value is shown in the bottom
display. This is the Display Loop. If the Setpoint is hidden or locked, the Display
Loop will default to Output Power. If Output Power is also hidden or locked out,
the bottom display is blank. During programming, the F1 key can be pressed to
return the controller to this point. (Only in the Display Loop will the F1 key
perform the user
F1In
function programmed in Input Module
1I
.)
When the A is pressed the controller advances to the next parameter in the
Display Loop. Except for Setpoint and % Output Power, the bottom display
alternates between the parameter name and its selection/value. The arrow keys
are pressed to change the selection/value for the shown parameter. The new
selection/value is activated when the A is pressed. Display Loop parameters
may be locked out or hidden in Lockout Module
3-LC.
Some parameters are
model and programming dependent.
