Manual
SERNUM
Pressing ALT followed by the "3" key displays the serial number of the unit.
DIAG
The DIAGnostics function will display a set of diagnostic aids to help to determine
the state of the DIGIMAX DIGIMAX DIGIMAX DIGIMAX DIGIMAX
®
. You must have a knowledge of how to use hexadecimal numbers
to use the diagnostic functions.
Pressing ALT followed by the "4" key causes an equals sign ("=") to appear in the left
lower corner of the display.
If the "1" button is then pressed, a two digit HEX number appears in the display which
represents the on/off states of the inputs on terminals 4 through 10 on TB2.
The number may range from "00" (all inputs off) to "3F" (all inputs on). The number "05"
in the display would tell the operator that the RUN and ESTOP inputs are on, and therefore
the DIGIMAX DIGIMAX DIGIMAX DIGIMAX DIGIMAX
®
should be running.
This number is structured as follows:
The first digit is bits 4-7 (7654 binary).
The second digit is bits 0-3 (3210).
bit 7 = Not used
bit 6 = Not used
bit 5 = Down input
bit 4 = Up input
bit 3 = Reverse input
bit 2 = EStop input
bit 1 = Preset input
bit 0 = Run input
If the "DOWN" input (not the front panel key) is activated while running, the number
displayed should be "23" (0010 0011).
ANAOUT
Pressing the ALT key and the "5" key displays the current value of the
Analog Output at terminals 13 (+) and 12 (-) on TB1.The display shows the letter "Ao" on the
left side of the display and the current value of the Analog Output in Engineering units, which
are controlled and scaled with parameters #28 through #30. (See parameters section).
Parameter #28 determines the source of the Analog Output signal and parameters #29
and #30 determine the minimum and maximum values, respectively. If parameter #28 is set
to "3", the Analog output value is set from the keypad. Simply key in a new number between
parameter #29 (0 VDC out) and parameter #30 (10 VDC out) and press ENT. The Analog
Output will go a the new value which is proportionally between the two.
AUXOUT
Pressing the ALT key and the "6" key brings up the AUXiliary OUTput menu.
The letters "Au" appear on the left side of the display. You can see the state of one of the
six auxiliary outputs by pressing the output number (1 through 6). If you then wish to change
the state of the output, you can press either the ON (UP) key or the OFF (DN) key and then
the ENT key to change the state of the output.
LOAD/AI
The value in engineering units of the Analog Input (TB2 terminals 15 and 17)
is displayed by pressing the ALT key followed by the "7" key. An "Lo" is displayed followed
by the value. Scaling is handled by parameters #22 and #23 (see parameters section).
PRESET
The DIGIMAX DIGIMAX DIGIMAX DIGIMAX DIGIMAX
®
may be forced into PRESET speed mode by pressing the
ALT key followed by the "8" key followed by the "UP" (ON) key. To turn the PRESET off,
press ALT, then the "8" key, then the "DN" (OFF) key.
