1. Press the AUTOSET button once and ASEt/F1
appears on the display.
2. Choose final torque target by pressing
+/- buttons.
3. Press the ENTER button once to activate the
AutoSet function.
The Graph LED, lights up.
4. Resume tightening (5-8 times) until the Graph LED
disappear.
Optimum performance has been found and the system is ready
for production.
KEY PAD FUNCTIONS
AutoSet Programming:
The AutoSet Programming
feature allows the DS Drive to
recognise a joint’s stiffness and
adjust the tool for maximum
performance for that particular
joint accordingly.

Fine – Tuning Final Target
This enables personnel to fine the final target.
1. Press the FUNCTION button once and Ft/F2
appears on the display.
2. Adjust final torque target by pressing
the +/- buttons.
(The torque can be adjusted a maximum of +15%
or –5% from the original final target).
3. Press the ENTER button and the display starts
to flash.
4. When a new final target has been found within above limits,
the DS Drive is ready to run that program.
Torque Tuning
This is used when a tool is controlled against an external torque
reference. If the torque value on the DS differs from the
traceable value, a Torque Tuning should be performed.
1. Perform a number of tightenings with the external torque
transducer connected, preferably 20 tightenings or more in
order to achieve a good mean value. Calculate the mean value
from the tightenings.
2. Press the FUNCTION button twice and tunE/F3
appears on the display.
3. Press the +/- button until you have the
external mean value on the display.
4. Press the ENTER button and the display starts
to flash.
5. Perform another set of tightenings to control your torque.
6. If the torque is OK you are ready to run. If not, do the
complete procedure over again.

Motor Tuning
This function will optimize the performance of the motor and
minimize losses, i.e. after service.
1. Press the FUNCTION button three times and
tool/F4 appears on the display.
2. Press the ENTER button until the display starts
to flash.
3. Press the trigger on the tool and the tool will turn both in
forward and reversed direction (about 35-45 seconds).
The tool has now been motor tuned and is ready to use.
Copy Parameter Set
This option makes it possible to copy a parameter set.
(D312 –Advanced functionality)
1. Press the FUNCTION button four times and
COPY/F5 appears on the display.
2. Press +/- button to select the parameter set
you want to copy to another parameter set.
Confirm by pressing the ENTER button.
3. Choose the parameter set that you want to
copy the selected parameter set to by
pressing the +/- button.
Confirm by pressing ENTER button.
Change Parameter Set
When neither of the described functions are selected, the +/-
button are used to change parameter set (D312 –Advanced
functionality).
1. Press the +/- button to change parameter
set.
2. Confirm that you want to change Parameter set by
pressing the ENTER button.

FULL PROGRAMMING
Tightening strategy
You can select strategy choices as shown.
Soft Start Time
In order to facilitate screw engagement the tool starts by
turning at a very low speed during the soft start time.
Targets
At
First Target the tool will shift from Step 1 Speed to Step 2
Speed . Final Target is the level where the tool stops and the
tightening is finished.
Speeds
Step 1 Speed is the speed used during the rundown. When First
Target is reached, the tool slows down to Step 2 Speed to
tighten the second stage. To finish the tightening the tool goes
in to
Zoom Step Speed for operator comfort and minimization
of overshoot.
Step 2 Ramp
In
Step 2 Ramp you can select the acceleration of the tool in
step 2 speed between 0 and 100%.

RUNDOWN MONITORING
Rundown Monitoring is a function to detect bad rundowns. The
angle in both first and second step is monitored. See graph
below.
Cycle Start
Cycle Start is the
torque limit from
which the angle is
measured. The
maximum limit for
Cycle Start is First
Target.
Search Speed
The Search Speed is
the speed with which the tool will run until Cycle Start limit is
reached. The min limit is 0%. Max limit is Step 1 Speed. When
Cycle Start is reached the tool immediately accelerates to Step 1
Speed.
Step 1 Turns
The angle in the first step is measured from cycle start level until
1st target is reached. Program min (0 turns) and max (200 turns)
levels for when the angle is OK. The angle is defined in 1/10 of a
full turn.
Clamp Angle
The angle in 2nd step is measured from the point where 1st
target is reached until final target is reached. The angle in
between is called Clamp Angle. Program min (0 degrees) and
max (10000 degrees) levels for when the Clamp Angle is OK. The
angle is defined in steps of 10 degrees.

9
HIGH SPEED RUNDOWN
High Speed Rundown allows the tool to make the rundown at a
higher speed than Step 1 Speed. The function is used when a
fastener has a long rundown angle and there is a risk for
overshooting when the joint is hard.
SELF TAP
The Self Tap function is used for thread forming screws and
other fasteners with a torque pulse in the beginning of the
rundown higher than the desired 1st target or final target, see
graph below.

CONFIGURATION
The Configuration window has three different subgroups:
System Administration, I/O Configuration (containing I/O Setup
and RE-Alarm Setup) and Tool Service Setup.
1. In System Administration you define the operator interface.
2. In I/O Configuration – I/O you define how to use the
different input and output connections on the DS Drive. For
cable connection, see page 11.
3. In I/O Configuration – RE-Alarm Setup you set the
characteristics for the external alarm. The RE-Alarm only
works for DS when its hex switch is set to position 3.
4. Tool Service Setup gives you information about the service
status of the tool and also a possibility to program your own
service interval, see page 12.
5. Selector Source decides what input is used to select
between p-sets. You can choose between:
❑None
❑I/O Digital
❑I/O Bus (Selector 4 and Selector 8, see page 11)
The I/O Bus only works for DS when its hex switch is set to
position 5 for Selector 4 and position 6 for Selector 8.
