2.2 BASIC OPERATION
Switch on the power to the controller. It runs through a self-test sequence for about three
seconds and then shows the temperature, or process value, in the upper readout and the
setpoint in the lower readout. This is called the Home display. It is the one that you will use
most often.
Figure 2-3 Home display
On this display you can adjust the setpoint by pressing the or buttons. Two
seconds after releasing either button, the display blinks to show that the controller has
accepted the new value.
Note: You can get back to the Home display at any time by pressing and together.
Alternatively you will always be returned to the Home display if no button is pressed for 45
seconds, or whenever the power is turned on. If, however, a flashing alarm message is present
the controller reverts to the Home display after 10 seconds.
2.2.1 Alarms
If the controller detects an alarm condition, it flashes an alarm message in the Home display.
For a list of all the alarm messages, their meaning and what to do about them, see Alarms at
the end of this chapter.
