It is forbidden to switch on the instrument unless the machine on which it
is installed conforms to 2006/42/EC Directive.
All of the equipments connected to the instrument must have insulation
characteristics in compliance with the regulations in force.
The instrument can be installed only by specialized personnel, following
the instructions provided by the Manufacturer.
It is strictly forbidden to intervene on the instrument while it is powered.
POWER SUPPLY From 90 Vac to 230 Vac ±10% - 50/60 Hz or, alternatively,
24 Vac ±10% - 50/60 Hz (by means of selector). We recommend the
use of a mains power supply provided with an input filter. The power
distribution network to which the instrument is connected must be
equipped with a sectioning device in compliance with the regulations in
force, positioned closed to the instrument.
GROUNDING The instrument is connected to the ground through the power supply
terminal block. To avoid discharges, we recommend the use of a
socket with a grounding connection. In case of inadequate grounding
connections, all the accessible parts, including those apparently
protected, may generate electrical discharges.
FUSES Unplug or completely disconnect the power supply before changing
the fuses connected to the terminal block in the rear panel. Use only
delay fuses ø5x20 mm 500 mA 250 V.
PREVENTION To avoid fires or explosions, this instrument should not be used in the
presence of inflammable gases, solvents, explosives, etc.

The instrument provides a series of visual signals to support the user during configuration
and use.
Wrong operations are signaled with the following message:
E r r o r
that temporarily appears on the display to inform the operator that the entered key is not
compatible with the current operation.
In case of “overflow” error, i.e. the number of digits displayed is greater than the instrument
counting capacity, the error is shown on the display as:
_ _ _ _ _ _
To exit this situation, enter a compatible position in the “Position Preset” parameter.
In certain situations, the error message will be accompanied by a number, indicating the
cause of the error. For example:
E r r 20
The list of possible errors is provided in the table below:
Error Number Description

When the mains power supply is disconnected, the instrument can retain in its memory all
the data and programs set.
When powered off, the instrument can also store the last axis counting position.
)
The instrument cannot consider shifts of the carriage made whenever the mains
power supply is disconnected (due to inertia, manual manoeuvres, or thermal
expansion). Whenever any of the above occurs, the positions shown in the display
are unreliable; they do not represent the new position of the carriage but the one it
had prior to power disconnection.

Parameter 03 – ENCODER PULSE CORRECTION
The correction factor CF is entered by the operator to adapt the machine linear shifting to
the number of encoder pulses (PPR).
For instance, in a machine with linear shifting correlated to the screw pitch, the correction
factor CF is calculated by the operator according to the formula:
SCREW PITCH (mm)
CF = ---------------------------------------
(RES * PPR * CNT)
Where: RES = axis resolution (see parameter 06)
PPR = encoder pulses per revolution
CNT = counting mode (see parameter 04)
Suppose we have a 100 PPR encoder, a 0.01 mm resolution and a x4 counting mode.
Example A with 4 mm screw pitch, example B with 5 mm screw pitch:
in case A: CF = 4 / (0.01 * 100 * 4) = 1.00000
in case B: CF = 5 / (0.01 * 100 * 4) = 1.25000
To compensate shifting, a CF value has to be manually entered.
