User's Manual Part 6

ProScale M150, M250 and all products with General Purpose LCD Digital Displays 32 of 32
Programming
Several functions of the digital display are user programmable. The following instructions
describe what features are available and how to change the system’s factory defaults to
customize the display for your application.
The keys pictured have multiple functions. Timing, which is how long a key is depressed,
and the combination of the keys pressed is important. This manual uses the term
‘”
momentarily
” to describe a key press of typically less than 1 second. Whereas
“press
and hold
” is used imply a key press of typically longer than 1.5 seconds. As an example;
when using a PC keyboard to type a CAPITAL letter you would “
press and hold
” the
SHIFT key and “
momentarily
depress the appropriate letter key.
The “
function
” associated with the key(s) pressed is executed on the key
RELEASE
, not
the key
DEPRESS
. This is important since some keys execute different functions based
on how long they are depressed. These key operations, once tried, quickly become
intuitive.
To enter programming mode,
press and hold
the
MODE
key and then
momentarily
press
the
0
(zero) key. The
MODE
key must be held for approximately 1 second before the
depression of the
0
(zero) key.
Once you are in the Programming Mode,
momentarily
pressing the
MODE
key will
advance through the Programming Parameter list.
To step backwards in the Programming Parameter list
press and hold
the
ON/OFF
key
and
momentarily
press the
MODE
key.
Momentarily
pressing the
+
(plus) key while displaying a Programming Parameter will
increase the parameter setting.
Momentarily
pressing the
-
(minus) key while displaying a Programming Parameter will
decrease the parameter setting.
Momentarily
pressing the
0
(zero) key while displaying a Programming Parameter will
revert the parameter to its factory default setting.
CAUTION: The Limit Mode
(See Programming Parameters 14,15 16 17)
functionality is
still active even while the display is in programming mode. Changing LIMITS may result
in the Limit/Monitor Signal hardware output becoming active immediately.
To exit programming mode,
press and hold
the
MODE
key and then
momentarily
press
the
0
(zero) key.
NOTE
: The display will automatically exit programming mode after 60 seconds of no key
activity.
