Reference Section: Operating Mode (oPER) 

Operating Mode is used to activate the unit’s monitoring and controlling func

tions. It also allows 

shortcut access to the Setpoint parameters while still running. Use Operating Mode to set the following 
parameters and perform the following functions: 

8. 

Reference Section: Operating Mode (oPER) ....................................................................................... 69

8.1

 

Normal Run Mode (oPER > RUN) 

 

Select Normal Run Mode (

RUN

). The ENTER button starts the unit operating according to the 

current input, output, and communications settings. Run Mode will automatically be entered 
and activated at unit power-on if the Power on Confirmation (

6.7.1 Power On Confirmation 

(INIt > SFty > PwoN)

) parameter is set to 

dSbL

. The process value is displayed in the main 

display, and if the unit uses dual displays, the current Setpoint value is displayed in the 
secondary display. With the unit remaining active, the 

oPER

 menu selections can be navigated 

to using the LEFT and RIGHT buttons. 

8.2

 

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 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.
