Initialisation
Upon subsequent power-ups of the DSi:
Rotate the axis in one direction
until the LED goes solid green
(K output goes ‘high’). This may
require up to 1 full turn.
Rotate the axis to its maximum
travel in both directions. The LED

DSi mounting options
Fitting slide locks
1) Remove the screw posts, washers and
external earthing tag from the rear of
SiGNUM interfaces.
2) Fit a screw and washer from the slide lock
kit into the lower hole as shown in this
diagram. Make sure the thread of the
screw is engaged but
leave the screw
protruding.
Fig. 1b
Fig. 1a
3) Holding the SiGNUM interface so that
the connector end is horizontal, lay the
washer in position over the other hole.

4) Note the orientation of the slide lock frame.
Slide the slide lock frame into position so
that it sits under the screw head, but on top
of the washers.

Calibration
Selecting a new propoZ position
The system must be calibrated if the installation is disturbed or if the DSi has been moved to a different axis.
The propoZ position can be re-programmed as many times as the user requires.
1) Install and calibrate each SiGNUM encoder separately as detailed in the SiGNUM SR/Si encoder system
installation guide (M-9752-0057). NOTE: The pin assignment of the DSi is the same as the SiGNUM Si
interface, so the same cable can be used.
Ensure the DSi is calibrated and has completed the initialisation routine. You will notice that the LED
on the DSi flashes ‘blank’ as it passes the last programmed propoZ position.
2) With the power off, connect the SiGNUM interfaces and output cable to the DSi .
NOTE: The SiGNUM interfaces connected to the DSi must have identical part numbers.
3)
!
Check the relevant head orientation switch position on the back of the DSi.
4) Use a small hex-key (or other suitable implement) to press and hold
the recessed propoZ button on the front of the DSi as the power
is switched on. The LED on the DSi will show red.
Now release the button and the LED will show orange,
then start to flash green. The K output will be ‘low’.
5) For complete rotation:
Rotate the axis in one direction until the LED stops flashing
(the K output will go ‘high’).
To change the propoZ position…
1) Rotate the axis to the position where you would ideally like the reference (index) position to be.
2) Using a hex-key or other suitable tool, press the recessed propoZ button on the front of the DSi.
The LED will show orange while the button is pressed. The new propoZ position is stored as the
button is released. If the axis remains at that position, the LED shows blank after the button is
released, indicating that the axis is
at the propoZ position.
Hint: you may find it useful to press and hold
the propoZ button while you adjust the
axis position slightly, then release the
button at the optimum point.
NOTE: The axis may need up to two full rotations to achieve this.
The DSi has now memorised the number of counts per revolution
and determined the factory default propoZ position.
For partial arc rotation:
Ensure the ring is installed so the reference marks are positioned correctly
(Refer to the REXM/REXT Installation guide M-9671-0021).
Rotate the axis in both directions to its maximum travel until the LED stops flashing
(the K output will go ‘high’). The factory default propoZ position has now been determined.
NOTE: For optimum system accuracy and performance at higher speeds ensure
that the AGC is swtiched off on the Si interfaces.
Initialisation (Required at each power-up and after an error)
1) The axis must be rotated in one direction (either clockwise or anti-clockwise)
until the physical IN-TRAC ™ feature on the ring passes both readheads.
The LED will then go solid green and the K output will go ‘high’.
2) Initialisation is now complete.
The propoZ reference (index) output will be given when
the axis next passes the propoZ output position.
If an alarm occurs, DSi will automatically re-enter
initialisation mode when the alarm condition is removed.
3) The controller may now ‘emergency stop’ as the reference (index) is output at a new position.
It is recommended that the controller is restarted to ensure the controller is using the new
reference (index) position.
4) After the controller has been restarted, the DSi will start the initialisation routine, indicated by
a flashing green LED and a ‘low’ K output . Rotate the axis in one direction (either clockwise or
anti-clockwise) until the LED goes solid green and the K output goes ‘high’.
The new propoZ position will be indicated by a blank flash of the LED.
NOTE: you can select a new propoZ position at any time when the LED is solid green,
simply by pressing the propoZ button.
5) Small black adhesive covers are provided for the propoZ button and head orientation switch to
reduce ingress of dust.
LED colour
Meaning
Green (flashing)
DSi is in initialisation mode. Rotate the axis in one direction until the LED
turns solid green to exit initialisation mode. NOTE: during high-speed
rotation, the blank flash of the LED as the axis passes the propoZ
position may appear like a flashing green LED.
If the LED continues flashing green check for correct position of the
orientation switch and press and hold the propoZ button on switch-on.
Green (solid)
Blank
Connections
DSi output
Function
Output type
Power
DSi is in normal working mode.
Axis is at the propoZ reference (index) output position. NOTE: if you drive
the axis past the propoZ position, the blank LED will appear as a 0.25
second flash.
Orange
(propoZ button is
being pressed)
A new propoZ position is being programmed. When the propoZ button is
released, the LED will normally show blank unless the axis is moved from
the propoZ position.
Red (solid)
Pulse count alarm has been asserted. The number of counts in the last
revolution is different to the value stored during the automatic calibration
routine when the DSi was first installed. This could be caused by a
miscount from one of the SiGNUM encoders. If the pulse count alarm is
asserted repeatedly, it is possible that an incorrect count is stored inside
the DSi, in which case the DSi should be powered-up with the propoZ
button pushed in to restore factory defaults. Re-calibrate the DSi as per
the initial installation. NOTE: on re-calibration, the old propoZ position will
be lost.
Red (flashing)
An alarm has occurred on one or both of the SiGNUM interfaces.
Red, then orange,
then flashing green
The DSi has returned to factory default settings. This is triggered by
pressing and holding the propoZ button while the DSi is being
powered up.
