53 Reference Section: Operating Mode (oPER)
6.2 Change Setpoint 1 (oPER > SP1)
Select the Change Setpoint 1 (
SP1
) parameter. This function allows Setpoint 1 to be changed
while remaining in Run Mode. Pressing the ENTER button after changing a Setpoint while in
RUN Mode returns you to RUN Mode with no interruption in monitoring, control, or
communications operations. If remote Setpoint is enabled, Setpoint 1 cannot be changed
here and the display will flash.
Set the desired value for Setpoint 1. When changing the setpoints from the operating mode
menu, the left arrow decreases the value with acceleration and the right arrow increases the
value with acceleration. This is different from the decimal place switching numeric change
control in other places as changes made here are usually limited.
Confirm the value.
6.3 Change Setpoint 2 (oPER > SP2)
Select the Change Setpoint 2 ( SP2 ) parameter. This function allows Setpoint 2 to be changed
while remaining in RUN Mode. The current value for Setpoint 2 flashes in the main display.
Setpoint 2 is only used for Alarms and as the cooling Setpoint in Heat/Cool Control Mode. See
6.2 Change Setpoint 1 (oPER > SP1) for additional information.
Set the desired value for Setpoint 2.
Confirm the value.
6.4 Manual Mode (oPER > MANL)
Select the Manual Operating Mode ( MANL ). This mode allows for control output levels or the
process input value to be manually changed.
Navigate to the desired Manual Operating Mode. The choices are as follows:
•
M.CNt – Manually vary the control output(s)
•
M.INP – Manually simulate change in the process input
Select the desired Manual Operating Mode.
Vary the Output or Input manually with the left and right arrows.
For M.CNt , the % On value is displayed instead of the process input value. With analog
outputs, the % On value specifies the output current or voltage as a percentage of the total
scaled range. With DC Pulse and Relay outputs, the % On value controls the width of the PWM
(pulse-width modulated) signal.
For
M.INP
, the process input value continues to be displayed but the value can be changed up
or down using the RIGHT and LEFT buttons, respectively. This is a “simulated value” and it can
be used to test out Alarm configurations, retransmission scaling, etc.
Exit Manual Mode and return to Run Mode.
6.5 Pause Mode (oPER > PAUS)
Select the Pause Operating Mode ( PAUS ) to pause the controller and hold the process input
at its current value. If in a Multi-Ramp/Soak program, the timer for the current Ramp or Soak
segment is paused as well. The current process value display will flash while in pause mode.
