Description
The electronic position indicator EP7, supplied with an internal battery, integrates in the same case
a position sensor and a display unit, and constitutes a device for measuring linear or angular
movements: it is compact, easy to install and applicable in many types of industry (packaging,
woodworking, aluminum, coil, etc.)
The display has 5 digit plus a sign (range -99999 +99999) with 7,5mm-high digits that allow an
excellent readability also at a distance.
With the 3 frontal buttons it is possible to program the value on the display for each turn of the
hollow shaft and activate the following functions: reset/preset of the displayed value,
absolute/relative displayed value, mm/inches conversion.
There are also 3 distinct origins available for the correction of the displayed value when using
different tools and the offset function for the compensation of tool wear.
On the display all activated functions are showed by a symbol.
The electronic parts are protected inside an elegant and resistant case made of self-extinguishing
and shock-proof plastic material.
The power supply is internal and is based on a single ½AA 3,6V battery which has a typical 4 year
lifetime. Low-power is indicated on the display with an icon; battery substitution is very easy and
does not cause loss of the correct displayed value when carried out without moving the shaft.
Mechanical installation
Fit the EP7 through its hollow shaft onto the machine shaft, taking care that the lock pin fits
correctly into the Ø6mm hole.
For this purpose, prepare the hole for the lock pin (bore 6,1mm, depth 6mm) ensuring that the
distance between the axis of the hole and the axis of the drive shaft is 30mm, see image 1 and 2
below. Then fit the instrument in and fix it with 2 M4 screws placed on the hollow shaft, see image
3 and 4.

3U6 are the values to display in origin 1 and in
origin 2 respectively.
ABS/REL function: Enables passing from an absolute to relative value; after pressing , the
displayed value is temporarily set to zero to measure a relative motion of the shaft. On the display
the REL icon indicates that the current display is relative to the reference point that has just been
created. Pressing again causes the absolute value to be displayed and the ABS icon will appear.
mm/inch conversion: Pressing converts the measurement from millimeters to inches and
back. When in inch mode, the INCH icon will appear and the displayed value will have an additional
decimal place. When the parameter QG(&
QG(&QG(&
QG(&=4 the mm/inch conversion is not available.
Offset: This parameter is added to or subtracted from the displayed value to correct it in case, for
example, of a tool change or to compensate tool wear. After setting a positive offset value, the
displayed value will be the measured value plus the offset value. After setting a negative offset
value, the displayed value will be the measured value minus the offset value.
Fast Offset: After pressing ENTER/RESET,2))6W

It sets the counting direction, allowed values 0 or 1.
By setting 0, the displayed value increases turning the shaft clockwise.
By setting 1, the displayed value decreases turning the hollow shaft clockwise.
Adjustment of displayed value
After the installation of instrument on the machine and setting of all parameters, in order to visualize
on the display the correct value it is necessary to carry out the reset or preset.
Position the shaft in a point in which the correct measure that has to be visualized is known exactly
(for example the stroke end point) or measure the position in that point of the shaft. Program
parameter W$6W,
W$6W,W$6W,
W$6W, with value 3 in the first digit on the right and exit programming.

Now press ENTER/RESET and 3U6W
3U6W3U6W
3U6Wwill appear, press again 2 times ENTER/RESET and set the correct
value to display, then confirm with ENTER/RESET. The display will now show the desired value.
If the required value is zero, instead of the preset function it is possible to use the reset function by
setting 1 in the first digit on the right in the W$6W,
W$6W,W$6W,
W$6W,parameter so that pressing ENTER/RESET will bring
the displayed value to zero.
Now that the instrument is adjusted, it is necessary to insert the desired W$6W,
W$6W,W$6W,
W$6W,parameter to avoid
accidental reset/preset of the displayed value.
Battery replacement
The instrument is supplied with a ½AA 3,6V lithium battery, which assures a typical functioning of
approximately 4 years.
When the battery runs down, an icon appears on the display.
To enter into the battery-holder it is necessary to remove the front cover by carefully inserting a flat
screwdriver on the sides. After taking off the cover, pull the battery out and substitute it with a new
one, paying attention to the polarity: the positive pole must face the side of the ENTER/RESET
button. The instrument is protected against inversion of polarity and wrong insertion, and in this
case will not switch on.
Removing the battery from the instrument switches it off after a few seconds: at this point do not
rotate the hollow shaft to avoid losing the correct displayed value. As soon as the battery is fitted,
the instrument switches on with the same value on the display which was present at the moment
when it was switched off. If the shaft has not be moved, the displayed value will be correct. In case
the shaft moved when the instrument was off, to re-establish the correct measure it is necessary to
repeat the adjustment process.
Display icons
1. Indicator of low battery, it is activated when is it necessary to change the battery.
2. Indicator of inches measurement.
3. Indicator for origin 1 and 2
4. Indicator of relative displayed value.
5. Not used.
