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 4 digit plus a sign (range -9999 +9999) with 7,5mm-high digits that allow an
excellent readability also at a distance.
With the frontal button 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.
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 5 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 EP3 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 22mm, see image 1 and 2
below.

Programming
Attention. The EP3 has a single key for all programming operations.
Within the programming menus it will be possible to enter/modify various configuration
parameters.
The procedure for entering/modifying a value is as follows:
•To change the value of the active (flashing) digit, press the key once (NOT prolonged or
long press).
•To change the active digit, press and hold the key until the next digit starts flashing. At this
point immediately release the key.
•To confirm the entered number, press and hold the key until the next menu item appears.
At this point, release the key.
Outside the programming menu, pressing the key can have two effects:
•Single pressure: the function set with the parameter Q7DVW, is performed
•Long press: access the programming menu
To access the programming parameters of the device, keep the key pressed and, after about 4
seconds, the writing 3$66 will appear on the display. Release the key and press it again for
about 2 seconds. 3 zeros will appear with the first one on the right flashing.
Set the value 273 and confirm. If the password is set incorrectly, programming will be exited.
Within the menu it will be possible to view and modify the instrument configuration parameters.
•To scroll through the menu parameters, press the key once (NOT prolonged or long press).
•To change the parameter value, keep the key pressed until the current parameter value
appears.
•At this point immediately release the key; the rightmost digit will be the currently active
(flashing) digit.
•To exit the menu, wait about ten seconds without pressing the key.
Available parameters :
1) 9,6 value to be displayed after one complete rotation of the shaft.
2) QG(& number of decimal places
3) W$6W, button activation mode
4) G,U counting direction
5) V$9( counting saving
1 ) Value to be displayed for one revolution of the shaft 9,6
This parameter, together with the following one, allows you to program the value to be shown on
the display for each revolution of the shaft. The permitted values are from 0.001 to 9999 with
setting of the decimal point position or, after having programmed the last digit to the left, by
pressing the key again (long pressure) the decimal point will flash and with a single press of the
key it can be move to the desired location.
2) Number of decimal digits QG(&
Represents the number of decimal digits to be shown on the display, permitted values from 0
to 4.
Example 1: for each revolution of the shaft there is a movement on the machine equal to 50, set
X,68$/ 50 and QG(& 0.
Example 2: for each revolution of the shaft there is a displacement equal to 12.345 and 12.3
should appear on the display. The constant Y,6must be set to 12.345 and the constant QG(& to
1.

shown on the display at the current position. This function is useful when the altitude on the
display needs to be corrected frequently.
4) Counting direction G,U
G,UG,U
G,U
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.
5) Counting saving 6$Y(
6$Y(6$Y(
6$Y(
Allowed values 0-1.
Writing ‘1’ forces the saving of the current position and configuration of the instrument in the non-
volatile memory. This function is only used to not lose the measured position if the battery is removed
for replacement.
Displayed value calibration
After having mounted the instrument on the machine and having set all the parameters, to view the
correct measurement on the display, it is necessary to reset or preset the displayed value.
Place the position of the shaft where the measurement to be displayed is precisely known (e.g.
mechanical stop position) or measure that point on the axis.
Program the parameter W$6W,
W$6W,W$6W,
W$6W, with the value ‘3’ and exit from programming . Now press the button
and the 3U6W

Battery replacement
The instrument is supplied with a ½AA 3,6V lithium battery, which assures a typical functioning of
approximately 5 years.
When the battery runs down, an icon appears on the display.
Before proceeding with the replacement, save the current dimension. Enter the menu and set ‘1’ in
the 6$9(
6$9(6$9(
6$9( menu. EP3 will proceed with saving the displayed value. Now the battery can be
removed.
To access to the battery compartment, remove the cover on the front by loosing the 4 torx screw.
Once the cover has been removed, remove the battery and replace it with the new one, respecting
the polarity: the positive pole must be on the side of the RESET/ENTER key and is marked with
the + sign on the electronic card.
The instrument is protected against polarity inversion and if the battery is inserted incorrectly it will
not turn on and will not suffer any damage.
Removing the battery, the instrument switches off within a few seconds, as soon as the new
battery is inserted, the instrument switches on with the quote on the display equal to the one just
saved. At this point it is necessary to re-enter the menu and reset the 6$9(
6$9(6$9(
6$9( parameter. EP3 will
restart again and the altitude displayed will be the one saved before replacing the battery.
