NOTATION CONVENTIONS FOR THE MENUS
Because of the number of features available in this control, information is included that
may not apply to your specific control. All usable features are included in this book, but
may not be used in your process. To increase clarity the following conventions are used:
1. Certain features, menu items, and functions shown in this book may or may not appear
on your control, depending on other menu item selections. At various places in the menus
there are notes identifying menu items that “control” or “direct” other menu items. If you
are looking for a particular menu item and can’t find it, check the menu item that is its
“control” for proper setting.
2. The “#” symbol is used in two ways. It is used inside a group of characters to indicate
which set point function (S P 1 or S P 2 ) is being affected. It is also used before a group of
characters of a menu item to indicate that there may be more than one selection or value
for that menu item. This is used for certain repeated items such as in the Ramp/Soak
Program section.
DISPLAY CONVENTIONS
The instrument front has two four digit displays, eleven indicators, and six keys. The
diagram on page 12 shows the location of the displays and descriptors.
During normal operation the top four digit display indicates the temperature that is being
read by the sensor. The bottom display indicates the set point. When you are
programming the instrument, the bottom display indicates the Menu Item being
programmed and the top display the value selected for that Menu Item. Error messages
use both the top and bottom displays to indicate a particular error.
Each character can only be displayed with seven light segments. Alphabet characters may
look peculiar when seen presented this way. The following is an example of the ‘seven
segment alphabet’ as used in the instrument:
A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
A b C d E F G H I J K L m n O P Q r S t U V U X Y Z
0 1 2 3 4 5 6 7 8 9
0 1 2 3 4 5 6 7 8 9
Notice that some characters are in upper case while others are in lower case. Some look
the same (e.g. G [G] and 9 [9 ]) and must be interpreted by context. Others are close (e.g.
B [b ] and 6 [6 ]), but different. Usually, the context of the term or value will help you
determine the correct character.
