Digital Input Configuration Page
Inputs 3 and 4 can be ordered as digital inputs. The digital input accepts a contact closure or a dc voltage input,
and performs some function based upon the digital event input status. For example, when the digital event input is
low, switch to a different auto set point value. If the digital event input goes back high, switch back to the original
control auto set point value. See Features chapter.
You can see and change all of the parameters on the Digital Input Configuration page. Only those that apply to
the function selected will be relevant. For example, you can set all of the Acknowledge Alarm parameters even
though you have Switch to Digital Set Point enabled. Only parameters relating to Switch to Digital Set Point have
any effect on the controller. If you change the function to Acknowledge Alarms, those alarm related parameters
previously entered are used.
Note: You must click Submit to send the new values to the Series PD.
