Getting Started 2704 Controller
3.5. THE AUTO MANUAL BUTTON
The controller has two basic modes of operation:
• Automatic Mode in which the control output is automatically adjusted to maintain the
process value at the setpoint .
• Manual Mode in which you can adjust the output independently of the setpoint.
The Auto/Manual button can only be operated from the loop view. Press the Loop Select
button to select the loop view, then press AUTO/MAN to toggle between auto and manual.
When the controller is in AUTO, ‘AUT’ will be displayed on the page (see Figure 3-4). The
middle readout will default to the Working Setpoint in a standard controller.
When the controller is in MANUAL, ‘MAN’ will be displayed on the page (see Figure 3-5).
The middle readout will default to Output Power in a standard controller.
If the loop summary page is not being viewed when the AUTO/MAN button is pressed, the
display will change to the first available loop summary. Subsequent presses will change
between Auto and Manual for the selected loop as above.
If the output is configured as On/Off, the output will be Off when the target output < 0.9 and
On when the target output is > +1.0.
