Function Keys User Inputs
The two user inputs are individually programmable to perform specific meter control functions. While in the Display Mode or Program Mode, the function is
executed the instant the user input transitions to the active state. The front panel function keys, ! and @, are also individually programmable to perform specific
control functions. While in the Display Mode, the primary function is executed the instant the key is pressed. Holding the function key for three seconds executes a
secondary function. It is possible to program a secondary function without a primary function.
In most cases, if more than one user input and/or function key is programmed for the same function, the maintained (level trigger) actions will be performed while
at least one of those user inputs or function keys are activated. The momentary (edge trigger) actions will be performed every time any of those user inputs or function
keys transition to the active state.
Note: In the following explanations, not all selections are available for both user inputs and front panel function keys. Displays are shown with each selection. Those
selections showing both displays are available for both. If a display is not shown, it is not available for that selection. USEr-n will represent both user inputs. Fn will
represent both function keys and second function keys.
USER INPUT ACTIVE STATE
Lo Hi
Select the desired active state for the User Inputs. Select Lo for
sink input, active low. Select Hi for source input, active high.
NO FUNCTION
No function is performed if activated. This is the
factory setting for all user inputs and function keys.
PROGRAMMING MODE LOCK-OUT
Programming Mode is locked-out, as long as activated (maintained
action). A security code can be configured to allow programming
access during lock-out.
INTEGRAL ACTION LOCK
Integral Action of the PID computation is disabled as
long as activated (USr = maintained action; Fn = toggle).
AUTO/MANUAL MODE
Places the controller in manual (user) mode as long as
activated (USr = maintained action; Fn = toggle). The
output is “bumpless” when transferring to/from either
operating mode.
SETPOINT SELECTION
When activated (USr = maintained action; Fn =
toggle), the controller uses Setpoint 2 (SP2) as the active
setpoint value.
PID PARAMETER SELECTION
When activated (USr = maintained action; Fn =
toggle), the controller uses the Alternate P, I, D, and filter
values for control. The controller initiates a “bumpless”
transfer during each transfer in an effort to minimize any
output power fluctuation.
SETPOINT RAMPING DISABLE
When activated (USr = maintained action), setpoint
ramping is terminated and unit will operate at the target
setpoint. When user input is released, setpoint ramping
will resume at the next setpoint change.
When Function key is pressed (Fn = toggle), setpoint
ramping is terminated and unit will operate at the target
setpoint. A second press of the function key resumes
setpoint ramping at the next setpoint change.
SELECT MAXIMUM DISPLAY
The Maximum display appears on Line 2 as long as activated
(maintained). When the user input is released, the previously selected
display is returned. The D or P keys override and disable the active
user input. The Maximum continues to function independent of the
selected display.
