1. INTRODUCTION
The DAC-310 is a universal programmable controller, designed to
control machinery for incremental displacement of machine parts
such as the back gauge control of an industrial shear. For a better
understanding the back gauge will be referred to throughout this
manual but it is possible for any device with a movement,
measured by an incremental encoder.
The DAC-310 is not confined to axis positioning but can program
parameters, related to other machine functions, as well.
It is possible to program several steps which can be combined to
a program. The DAC-310 is capable of controlling servo-loop
systems, a one- or two-speed AC or DC drive system.

3. OPERATING MODES
3.1. General
The DAC-310 has three operation modes:
• Manual mode
• Automatic mode
• Semi-automatic mode.
The DAC-310 can be programmed with 100 steps (0 - 99). You
can browse through the steps by pressing the + and - keys.
Manual mode is selected by moving to Step 0.
Automatic mode is selected when a program has been entered
and you move to the first step. Then you press the key for
automatic production.
Semi-automatic mode is simply selected by pressing the key for
semi-automatic.
Both keys (automatic and semi-automatic) also serve as start
buttons for each mode.
When the automatic or semi-automatic key is pressed the DAC-
310 will position the back gauge according to the programmed
parameters in the selected step.
The LED of the corresponding key (either automatic or semi-
automatic) will light up.
When the stop button (O) is pressed the DAC-310 will keep the
back gauge at its actual position. The LED of the stop button will
light up.
In some situations the "stop" is forced by the DAC-310 itself. In
that case the LED of the relevant start button extinguishes and
the LED of the stop button lights up.
In the following paragraphs the three operating modes are
described.

V0504, 8
When the start button is pressed the parameters Xm and Xp are
displayed, the programmed position and the actual position.
When the axis reached the programmed position, Xp is
highlighted and has the same value as Xm.
When the stop button is pressed the cursor moves back to the
selected parameter.
3.2. Manual mode
Manual mode is active in Step 0. It is indicated with
the hand symbol in the upper left corner.
In Manual Mode all parameters can be programmed.
When the automatic or semi-automatic key is pressed (start
function) in manual mode the back gauge moves to the
programmed position.
The stock counter (#) will be either incremented or decremented
at each manual cycle, depending on the setting (refer to chapter
4.3.8).
When the stock counter reaches zero in down counting mode the
DAC-310 stops. The # value is displayed at the top of the display.
The back gauge can be moved manually by pressing front keys.
To do so, the control must be stopped (the LED of the stop button
is lit). First move the cursor to the parameter Xp. The hand
symbol is now surrounded by two arrow symbols.

V0504, 9
Now the axis can be moved by pressing the manual movement
keys on the front panel. These keys are:
+ = slow speed in counting up direction
- = slow speed in counting down direction
X = high speed, must be pressed together with the + or - key.
3.3. Automatic mode
In Automatic Mode a program can be executed.
When the automatic key is pressed the back
gauge moves to the programmed position of the
first step.
The execution of different program steps is controlled with the
START input. When this input is switched from low to high, the
axis (back gauge) moves to the programmed position. When
switched from high to low, the next step is loaded.
DAC-310 Delem
V0504, 10
If the value for step repetition CY is higher than 1, only the value
of CY in the current step is decremented by 1 and no new step
will be loaded.
When the Automatic key is pressed to start a program, the control
automatically starts at Step 1. This happens whether or not the
parameter ST is programmed higher than zero. See chapter 4 for
more information about parameter ST.
3.4. Semi-automatic mode
The semi-automatic mode serves to execute a program step by
step.
The Semi-automatic Mode is started with its
own start key.
The execution cycle of a step runs similar to the one in automatic
mode. There are the following differences.
• The DAC-310 stops at the end of each step.
• A program is started at the step that is currently selected.
If the programmed value for CY is higher than 1 a number of
cycles equal to this value must have been executed before the
DAC-310 stops.
In semi-automatic mode you can choose to execute a program
step by step or execute a number of steps from the memory. This
depends on the value of the ST parameter. This will be explained
in detail in chapter 4.

4. PARAMETER PROGRAMMING
4.1. Introduction
The DAC-310 is a programmable back gauge controller.
The DAC-310 can also program parameters, related to other
machine functions.
One such set of parameters is referred to as a "step".
Several steps can be combined to build a program. During the
execution of the program the steps within the program are
executed one after another in an automatic cycle. The control
switches to the next step when a Start/Enable signal is received.
4.2. Identification of a step
A step is identified by a number in the range 0-99. This means
that up to 100 steps can be programmed and stored into memory.
Step 0 is an exception. This step is the manual mode of the
control and is never part of any program.
The number of the selected step is displayed in the upper left
corner of the display.
The keys + and - are used to browse through the available steps.
Holding the keys + or - will speed up the effect.

4.3. Programmable Parameters
4.3.1. General
A parameter can be programmed upon selection. The selected
parameter is indicated by a symbol. Selecting a parameter is
done by pressing the arrow keys. The actual value of the selected
parameter is displayed.
Each programmed parameter is checked against its minimum and
maximum value. If a programmed value is invalid the value will be
limited at its minimum or maximum value.
The function Xp is not a programmable parameter. If Xp is
selected the actual position of the back gauge is displayed.
The parameters are:
- Xp = actual position of the back gauge
- Xm = programmed position of the back gauge
- # = Stock counter: counting of products
- ST = the number of steps
- M = entry point for programming constants
4.3.2. Actual position readout Xp
If Xp is selected the actual back gauge position is displayed.
If the reference has not passed yet only a dashed line is
displayed.
When a programmed step is shown, Xp cannot be selected as a
parameter, it can only be read from the central part of the display.
You can only select Xp when you are in manual mode (step 0).
Then you can move the axis with the +/- keys.
4.3.3. Back gauge position Xm
Xm is the intended position for the axis. Xm must be programmed
to the required value.
Delem
V0504, 13
Everytime a step is executed, the axis moves to the programmed
position Xm. The actual position is shown by Xp. When the axis
has reached position, Xp has the same value as Xm. Xp is then
highlighted on the display.
When the cursor is at Xm a value is displayed with a format
depending on machine settings.
Either millimetres or inches is possible.
Note:
The back gauge position can also be programmed negative. In
that case, it is considered as a chaining value.
4.3.4. COR(rection)
Correction on the programmed back gauge position.
The value to be programmed at COR appears in the same
resolution as Xm.
Default: 0
Note: the presence of this parameter depends on machine
settings
4.3.5. Retract distance DX
In some cases it may be necessary to clear (retract) the material
from the back gauge. This may occur at the moment when the
mechanical action begins. The retract distance is a programmable
displacement of the motor axis in the up counting direction.
The value at DX appears in the same resolution as Xm.
Default: 0
Note: the presence of this parameter depends on machine
settings
DAC-310 Delem
V0504, 14
4.3.6. Function Outputs F
There are two function (on/off) outputs: F1 and F2.
The value of these two outputs can be programmed as one
parameter.
There are four combinations:
Value F2 F1
00 off off
01 off on
10 on off
11 on on
Default: 00 (both off)
A combination can be programmed with function F.
The digital outputs will be set to the programmed value when the
start-enable input becomes high while the DAC has been started.
The outputs stay at the actual value during the program step and
will be reset when the DAC is stopped.
Note: the presence of this parameter depends on machine
settings
4.3.7. Repetition CY
Step repetition: the number of times a step is repeated before the
next step is executed.
Range : 0 - 9999
Default: 1
Note 1:
The value 0 means that the step must be skipped.
Note 2:
This parameter has no meaning in Manual mode and is equal to
0.
Note 3:
The presence of this parameter depends on machine settings
