2604 Controller Operation3.3. THE AUTO MANUAL BUTTONThe controller has two basic modes of operation:• Automatic Mode in which the output is automatically adjusted to maintain the processvalue 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 Selectbutton 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 loop summary page asshown in Figure 3-3 (LP1). The middle readout will default to the Working Setpoint in astandard controller.When the controller is in MANUAL, ‘MAN’ will be displayed on the loop summary page asshown in Figure 3-3 (LP2). The middle readout will default to Output Power in a standardcontroller.If the loop summary page is not being displayed, pressing the AUTO/MAN button will selectthe first available loop summary. Subsequent presses will change between Auto and Manualfor the selected loop as above.3.4. THE RUN/HOLD BUTTONIf the controller is configured as a programmer this button has three functions:• To put the programmer into RUN mode. This causes the working setpoint to follow theprofile set in the program being used.• To put the programmer into HOLD mode. This stops the program from running andmaintains the setpoint at the current level..• To put the programmer into RESET mode. This resets the programmer to the controllersetpoint, the working setpoint can be changed manually using the Raise/Lower buttons.If the controller is in reset or hold mode, press the RUN/HOLD button. The program beginsto run, and the RUN LED illuminates.If the controller is in run mode, press the RUN/HOLD button. The program will hold at itscurrent conditions, and the HOLD LED illuminates.If the controller is in run or hold mode, press the RUN/HOLD button and hold it pressed fortwo seconds. The program will reset, and the RUN and HOLD LEDs will extinguish.This button operates all programmer loops simultaneously.See also Chapter 4, ‘Programmer Operation’.User Guide Part No HA026491 Issue 3.0 Apr-02 3-5
