Menu Structure
Displaying Setpoints
To view setpoints or operating conditions press the ‘Prev Menu’ or ‘Next Menu’ key until menu of
interest appears. (Remember pressing a key in the Category group goes to the first menu of that
group) To view additional setpoints or conditions under the menu selected press the ‘Prev Item’ or
‘Next Item’ key.
Changing Setpoints
Setpoints / values that can be modified are under the control and alarm categories. Once the menu is
selected, the setpoint / value can be changed by pressing the ‘+ incr.’ or ‘- decr.’ key. The display
screen will change and in place of the date and time the term “Enter Password:” will be displayed. The
operator must enter the appropriate password by pressing the correct four keys in sequence. The
display will indicate “Password Verified:” or “Invalid Password:” in place of the time and date. When
the correct password is entered, the term”<Change Values Mode>“ is displayed in place of the time
and date. The first value on the display that can be changed will flash on and off. Pressing the
‘Next/Prev Menu’ or ‘Next/Prev Item’ keys will select the next setpoint / value on the screen that can
be changed. Pressing the ‘+ incr.’ or ‘- decr.’ key will change the numeric value or select the next
option. When the correct value or option is flashing, press the ‘enter =‘ key to store it into memory.
Pressing the “Enter” key a second time or pressing “Clear”. Screens and menus cannot be changed
while in the Change Values Mode. (The term “Enter Password” will not be displayed unless there has
not been any keypad activity for five minutes.)
Display Screen
The display screen is divided into lines and fields. The top line will indicate the menu number and a
menu description on the left side, and the time and date on the right side. The time and date will be
replaced with directions when modifying setpoints and values.
The first line normally will have two fields except when viewing alarms then there is a third field. Line
2 and line 3 have two fields. Different menus will have varying amounts of information and not all the
fields will be used.
When selecting new menus using the 'next menu' and 'prev menu' keys, the display is considered
screen one. If additional screens are available, there will be an arrow pointing down in the last block in
the right hand screen corner. To obtain additional information available under a specific menu, press
the 'next item' and 'prev item' keys. This will toggle between the available screens displaying the
various setpoints and values. Most menus will have only one screen. The range of information that
can be displayed in a field is extensive and the next section will show all possible field names,
setpoints and values.
