PARAMETERS AND HOW TO ACCESS THEM

Parameters are settings, that determine how the controller will operate. For example, alarm setpoints are parameters that set the points at which alarms will occur. For ease of access, the parameters are arranged in lists as shown in the navigation diagram on Pages 2-10 and 2-11. The lists are:

Home list	Autotune list	Output list
Probe list	PID list	Communications
Care list	Motor list	list
User list	Setpoint list	Information list
Alarm list	Input list	Access list.

Each list has a ‘List Header’ display.

List header displays

List name

Always displays LiST

Figure 2-5 Typical list header display

A list header can be recognized by the fact that it always shows ‘LiSt’ in the lower readout. The upper readout is the name of the list. In the above example, ‘AL’ indicates that it is the Alarm list header. List header displays are read- only.

To step through the list headers, press . Depending upon how your controller has been configured, a single press may momentarily flash the display units. If this is the case, a double press will be necessary to take you to the first list

header. Keep pressing to step through the list headers, eventually returning you to the Home display.

To step through the parameters within a particular list, press . When you reach the end of the list, you will return to the list header. From within a list you
