INSTALLATION
W A R N I N G !
Do not switch on the instrument unless the machine conforms 98/37/EC
regulations.
The installation of the instrument must be carried out by authorised skilled
staff who will follow the regulations stated by the Manufacturer.
EARTHING The instrument is connected to earth by means of the power supply
PROTECTION According to power supply:
connector. In order to avoid discharges it is advisable to use an
earthed socket. If the instrument is not connected or is improperly
connected to earth, all the accessible parts, including those which
may appear to be protected, may generate electrical discharges.
Under no circumstances is it possible to access the inside of the
instrument when it is powered from the mains power supply or by
other power-supply devices.
q 230 Vac - 50/60 Hz or 110 Vac 60 Hz by fuse located on the
rear panel (use only delayed-action fuses, φ 5 x 20 mm, 500
mA 250 V).
q 24 Vac 50/60 Hz by an automatic brake circuit (self-
restoring), in case of overcurrent, short circuit and so on.
PREVENTION In order to avoid the possibility of fires or explosions, this
instrument may not be used in the presence of inflammable gases,
solvents, explosives, etc.
REAR This may be removed exclusively by specialised personnel, and in
PANEL any case after disconnecting the instrument from the mains power
supply (it is not sufficient to place the switch in the OFF position).
INSTALLATION Install the measuring scales (or rotary encoders) in accordance
with the Manufacturer’s instructions. Connect the Axis connectors
to the corresponding inputs (X,Y and Z) on the instrument. Connect
the power supply cable and then switch on the instrument (key-type
switch on the rear).
IMPORTANT NOTE: The instrument is protected against incorrect
information caused by uncertain situations (due, for example, to sudden or
momentary mains voltage drops). In these cases, in order to inform the operator
that an accidental upset of this type has occurred, when the instrument is switched
on again, it prompts the operator to find the scale zero (rEF).

® FLASHING AXIS LED ˜ STEADY AXIS LED
The instrument provides a series of acoustic and visual signals to indicate the succession of
the settings. Every time a key is pressed, a “short” sound of a buzzer is heard, while
messages consisting of wordings or numbers appear on the display depending on the type
of setting made (see manual). Finally, the Axis LED underlines the activation of the axes
or that they have been set to perform (or to have performed) a given function. If the LED
flashes, the function is in progress, while if it is steadily lit (or if it extinguishes), the
function has been completed and performed.
In the event of incorrect entries, an acoustic alarm consisting of a “long” buzzer signal will
occur, accompanied by a visual alarm consisting of the following message:
E r r o r
This appears momentarily on the display in order to inform the operator that he has
pressed a key which is not compatible with the operation being carried out.
In the event of “overflow” errors, which occurs if measurements having a number of
digits greater than the counting capacity of the instrument are entered, the error is
indicated on the display as follows :

RETENTION OF DATA AND PROGRAMS
Program setting of VISION is carried out beforehand by the Manufacturer, who is aware
of the access codes and of the procedures (configuration). The user can then enter the
settings required for using it. All the information is permanently stored, and can only be
changed voluntarily, by re-entering it. The instrument is also able to “remember” the last
piece of data acquired, when the power supply is switched off.
In addition to the information referred to above, the following will
also be retained:
A) The selected unit of measurement (MM/INCH).
B) Confirmed function settings, with the exception of the scale
factor and variable resolution.
C) The last Axis counting position, and any messages (not of the
transient type) indicating abnormal situations, such as :
_ _ _ _ _ _ _ _
To clear all the “operational” settings entered (resetting of counters, origins of the Axes,
tool offsets, etc.) see function “F0”
IMPORTANT Either the instrument is in the ABS or the INC mode, it is unable to
consider any shifting of the Carriages (due to inertia, manual
repositioning or thermal expansion) when there is no power supply. If
this occurs, the measurements indicated on the display will no longer
be reliable, since they will be unable to show the new position of the
Carriages but only the one before the instrument switched off.
In order to avoid errors, which may be even considerable, the operator
must consider the opportunity of relating the ABS/INC counting mode
to the scale zero reference (rEF). He will link to rEF all those functions
which he intends to use and which require this condition, as specified in
the descriptions related to the single functions (it is recommended that
these descriptions are carefully read).

The displays remain on and show the zero search (rEF). Press CLR to enable the Axes for
counting. Move the Carriages by hand and decide which Axes need to be reversed (the
direction in which they advance depends on the mode of application of the rulers, and is
therefore random).

SCALE ZERO REFERENCE (rEF)
The ruler zero reference (rEF) can be considered a precision micro-contact, generally
located at the midpoint of the travel. Its position in relation to the geometrical trim of the
machine is invariable in time, and can only “move” if the scale is disassembled (for
servicing, maintenance or replacement), and re-assembled differently. In this case the
operator will have to set the references again. When using scales with reference marks at
coded distance, the research of rEF is completed after a travel of appr. 20 mm on the
travel direction. Note: for a correct rearrangement of rEF position, on scales with
reference marks at coded distance, it is important to properly set the counting way,
according to the installation instruction. The zero rEF can be searched either in
automatic mode, every time the instrument is switched on, or in manual mode:
A) Automatically, every time there is a momentary or long-lasting interruption of
the mains power supply, either voluntary or otherwise, in order to avoid presenting
the operator with incorrect numerical values (LAST POSITION), the instrument
displays a prompt to the operator suggesting a new scale zero (rEF) search. This is
the case, for example, in the event of a sudden power failure occurring while the
Carriage is moving (since it would continue to move due to inertia), or movements
due to thermal expansion (due, perhaps, to a temperature drop at night), or
involuntary or accidental shifting (while cleaning the machine, for example). In this
way, the operator is warned that there is a probable “risk situation”. He may decide
to carry out a scale zero (rEF) search by passing the Carriages over the
corresponding points, or else to cancel the scale zero by pressing CLR (this should
be done in any case if the rulers do not have the ruler zero reference. In this case it
is advisable to check the precision of the positions reached).
B) Every time the operator thinks that it is necessary, he can check the positions
reached by the Carriages by setting the scale zero (rEF) search manually on the
Axes concerned (or on all the Axes).
For example enter:

The LEDs of the activated Axes flash and indicate that the instrument is ready

NOTES: Every time an Axis completes the ruler zero (rEF) search, it is automatically excluded
from this function so that it will not interfere with the other operating conditions. In any
case, the instrument will not accept any settings until all the Axes have terminated the
ruler zero (rEF) search, and will display an error message if any keys except CRL are
pressed. The operator may then decide to proceed as follows:
A) to complete the zero search for all the Axes activated;
B) to carry it out for the Axis concerned and cancel it for the remaining Axes;
C) to cancel the search right away for all the Axes because it is considered superfluous.

SELF-TESTING
A general test of the instrument is carried out every time it is switched on, and the validity
of the data stored in the memory is checked. If this is found to be reliable, while the
function is being performed the following wording will appear on the display for a few
seconds:

ABSOLUTE/INCREMENTAL COUNT
The LED of each Axis always signals the following:
• AXIS LED ON = AXIS IN ABSOLUTE COUNT (ABS) MODE
• AXIS LED OFF = AXIS IN INCREMENTAL COUNT (INC) MODE
• AXIS LED WILL FLASH = FUNCTION BEING PERFORMED
It is possible to switch either a single Axis or all the Axes from one counting mode to the
other as follows :
X and/or
key
The LEDs of the activated Axes will flash
press
The LED will light up (or extinguishes) and signal that the Axis is in ABS (or INC) mode.
The counting system is managed by the instrument, which has a dual internal counter
(ABS/INC) for each Axis. The information relating to the movement of the Axis updates
both counters at the same time. The information entered by the operator, on the other
hand, only affects the counter of the selected counting system. It goes without saying that
if the ABS counter is reset at a given point of the travel (ORIGIN) and the
INCREMENTAL counting mode is used (this is handier and more versatile to use), the
operator can then carry out all the resetting, pre-selections, functions and so on required
by the machining process, since he can return to the ABS count at any time to find out the
“absolute” positions of the Carriages at that time and thus find the ORIGINS which had
been set.

MMS/INCHES CONVERSION
Every time the following key is pressed the unit of measurement is switched from
MM to INCHES or vice versa. Switching takes place instantaneously for all the Axes
being counted. The selected unit of measurement is shown by the position of the LED lit
on the keypad, and also by the position of the decimal points for the Axes being counted.
If activation of the conversion is not compatible with the operational conditions of the
instrument, pressing this key will cause an error message to be displayed.
WORKPIECE CENTRE
This function makes it easy to identify the centre between two points A and B of a
workpiece being machined (distance between centres of holes, geometrical figures, sides
of the workpiece, etc.). To perform the function, for example on the Y Axis, proceed as
follows:
A) Go to the first position, A, by moving the Carriage along the Zo Axis.
Let us suppose that in this position the display of the Y Axis indicates
the dimension 30.00 (which it is not necessary to reset):
B) Key
Both the LED of the Y Axis and the LED of the ½ symbol will flash on the keypad.
The auxiliary display will show the wording “WORKPIECE CENTRE”.
C) Now go to the second position, B. Let us suppose that in this position the display of
the Y Axis shows the dimension 52.22
D) Key
The flashing LEDs will extinguish and a dimension will appear on the display of the
Zo Axis. This dimension is exactly half (rounded off, if necessary) of the path followed
by the Carriage between the two positions A and B. It will be sufficient to move the
Carriage as far as dimension “0.00” for it to be located exactly on the required
midpoint.

the workpiece has been completed. If it is not necessary to repeat the same operation on
other
workpieces, press CLR. If it is, press REF. The display will indicate the total value of the
last
position reached, that is to say:

A) The counting direction must be the same as the direction of displacement (if
necessary, use +/- to reverse it while entering the pitch, that is to say: 13.75 +/-
EXE).
B) Carrying out holes in succession does not lead to errors of the “cumulative” type,
even if the positions have not been reached with great accuracy by the operator.
C) It is not possible to perform any other functions during this operation.
