Programming Keys Defi ned
The Interface Module has four keys located on the front panel. These keys are used to program
functions and perform basic operations.
The function key is used to begin a process for programming a function.
When this key is pressed, the Interface Module prepares itself for the entry
of a specifi c function number.
The scroll key is used to scroll through the Interface Module’s list of
function numbers, as well as, other lists. To scroll to a particular function
number, continue to select the scroll key (after selecting the function key)
until the Interface Module displays the desired function number. The
scroll key is also used to increment selected digits on the monitor’s LED
display. Incrementing digits can be done to either select a function number
or a value for a function. To move to a specifi c digit on the display, use
the shift key. A fl ashing digit indicates it is activated to be incremented.
This key can also be used to get you quickly out of an incorrect parameter -
rather than having to restart the function entry process. For example, if an
invalid parameter was entered in the Upper End Limit function, you could
select the scroll key. This would take the monitor back to displaying the
current value, where you could re-enter a new value.
