Manual
The proper operation of the
DIGIMAX DIGIMAX
DIGIMAX DIGIMAX DIGIMAX ® requires a complete understanding of the front
panel controls. Speeds, ratios, and parameters will be set by the operator with the keypad,
which consists of numerical and action keys. The display and the LED's will supply important
information during setup and while the process is in operation.
The numeric display of the
DIGIMAX DIGIMAX

is normally lit up
while power is applied. There are, however, times at which the
display will be blank. One condition under which the display
blanks while power is on is when the PGM/CLR button is pressed
just prior to entering the access code. The access code may then
be entered. Another occasion when the display goes blank is after
the ALT key is pressed until one of the keys with a command in
small letters above it is pressed.
The display is a full five digits, allowing numbers up to 99999 to be displayed. A decimal
point may be placed between any two of the five digits, allowing numbers to be displayed
or set down to 0.0001.
The display has two levels of brightness to indicate the mode in which it is operating.
The COMMAND mode is a dimmer display. In COMMAND mode the display shows the
SETPOINT value. The ACTUAL mode is a much brighter display. In ACTUAL mode the
display shows the actual speed of the motor in whatever scale is set up by the parameters.
See the explanation of the COM/ACT button below.
The AT SPEED indicator changes only in the MASTER mode, indicating that the actual
motor speed is within the programmed tolerance. In SLAVE mode the AT SPEED indicator
is on all of the time except when slewing to a newly entered ratio.
The REMOTE indicator is on when remote operation is on. In one REMOTE mode, the
keypad is locked out unless the unit's LOC/REM key is pressed. In another mode, even the
LOC/REM key is locked out.
The number keys on the
DIGIMAX DIGIMAX
DIGIMAX DIGIMAX DIGIMAX ® are used for :
1. entering speeds and ratios into the unit while the unit is in operation. Speeds and
ratios may range from one to five digits, from 0.0001 to 99999;
2. entering the security code to gain access to the parameters. The security code may
vary from 1 to 5 digits. It is not necessary to enter leading zeroes;
3. entering parameter values while in setup mode. The parameter values may range
from one to five digits.
The
DIGIMAX DIGIMAX
DIGIMAX DIGIMAX DIGIMAX ® will not accept more than five digits in a single number. When a
number is pressed, the microprocessor enters the number entry mode. As numbers are
entered, they are displayed in the display (except in the entry of security codes, when dashes
are displayed). On the sixth consecutive digit a new five digit number is started. This feature
may be used to advantage when an incorrect number is pressed during an entry. Simply
keep pressing numbers until the display is full, then enter the correct number sequence.
The ENTER button must be pressed before any numerical data is entered into the
DIGIMAX DIGIMAX
DIGIMAX DIGIMAX DIGIMAX ® . Numbers may be pressed continuously, but nothing will happen until the
ENTER button is pressed. The ENTER button must be pressed after the security code, after
speed or ratio command entries, and after parameter values are entered. The ENTER button
is not used for function keys such as UP , DN , SET , COM/ACT, or LOC/REM.
The ENTER key may also be used to clear error codes (see page 27).
