Modifying the Display Pairs
The Home Page, being a customized list of as many as 20 parameters, can be congured in
pairs of up to 10 via the Display Pairs d.prs prompt found in the Global Menu
gLbL
(Setup
Page). The listing in the table that follows is what one may typically nd in the Home Page
as defaults based on controller part numbers. It is important to note that some of the
prompts shown may not appear simply because the feature is not being used or is turned off.
As an example, the prompt shown in position 7 (loop 1) and position 12 (loop 2)
C.pr
will not
appear unless the Cool algorithm
C.ag
is turned on in the Setup Page under the Loop menu.
If the ninth digit of the part number is C, J, L or M (PM _ _ _ _ _ - _ [C, J, L, M] _ _ _ _ _)
the Display Pairs d.prs prompt will default to 2; otherwise, it will be equal to one.
As stated above, the user can define pairs of prompts to appear on the display every time
the Advance ‰ key is pushed. The first pair will always be as defined in the Custom Menu
and as stated, will default (factory settings) to the Active Process Value loop 1 aC.pu, and
the Active Set Point loop 1 aC.sp. If two channels are present the rst 2 pairs will be the
same in that the rst pair will represent channel 1 Active Process Value and Active Set Point
and the second being the same for channel 2. If another pair is created where the Display
Pairs d.prs prompt is equal to 3 using the default prompts, when the Advance Key ‰ is
pushed two times from the Home Page the upper display will reect the current control
mode and the bottom display would show the output power. When conguring the Custom
Menu to your liking it should be noted that if a writable value is placed on the upper display
and is paired with another read only parameter on the lower display, the arrow keys will af-
fect the setting of the upper display. Also, if 2 changeable (writable) prompts are displayed
in a Pair, i.e., Control Mode on top and Idle Set Point on the bottom, only the lower display
(Idle Set Point) can be changed.
The display can be congured to scroll customized pairs by going to the Setup Page under
the Global Menu and changing the Display Time d.ti prompt to something greater than 0 and
by changing the Display Pairs d.prs to something greater than 1. If the Display Time d.ti is
set to 2, the display will toggle every 2 seconds from the rst display pair to the second and
then the third, etc... If the control has more than one channel and one of the congured
pairs is set as instance 2, the channel indicator (LED) will change from 1 to 2 reecting the
channel of the pair being displayed. The display will continue to toggle through all of the
custom pairs at the specied time interval.
