Reference Section: Operating Mode (oPER)
8.3
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
7.1 Change Setpoint 1 (oPER > SP1)
Set the desired value for Setpoint 2.
Confirm the value.
8.4
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.
