1 - INTRODUCTION
The CPO optical counting sensor is a detection tool which, thanks to its sensiti ity and
adjustment characteristics, is the answer to all counting problems for objects in any
material or shape, both free falling and forced.
It also offers the opportunity not to count objects in sizes under those desired, such as
machining waste for example, which could accidentally cross the reading area.
2 – WARNINGS
- ATTENTION: for correct use of the equipment, it is essential to comply with the
instructions in this manual. You are ad ised to read each part of it carefully before
start-up, to pre ent possible damage due to improper actions.
- The equipment MUST NEVER be used as a detection de ice to protect people.
- Do not use the equipment in en ironments with a dangerous atmosphere
(inflammable or explosi e).
- Only use in enclosed en ironments not subject to water sprays.
- A oid fumes or mist passing through the reading area, which could cause false
readings or detection loss.
- The power supply must comply with the operating oltage planned and it is preferred
not to share such supply with motors, relays or solenoids whose acti ation could
reduce sensiti ity or cause false detections.
- Connect the body of the sensor to the ground, using the best support to reject external
electrical disturbance.
- A oid sunlight or stroboscopic flashes directly striking the equipment.

5 – INSTALLATION
Fasten to a stable support using the two, 4.5
mm holes prepared so the pieces to signal, on
falling, pass through the acti e reading area.
The CPO can also work in the presence of small ibrations produced by surrounding
equipment; you should remember that these ibrations should ha e an intensity normally
supportable by an electronic control. If ibrations are more intense, you are ad ised to use
specific dampening supports.
The counting scale can work in any position; assembly that is not horizontal promotes fine
dust gathering on the reading glass, thereby damaging count efficiency.
A oid positioning the equipment in the direction of ery intense light sources (direct sun-
light or ery powerful lamps), e en if it can automatically adapt to en ironmental light
ariations.
Remember the sensiti ity of the peripheral zone of the reading area cannot be considered
3

uniform; you are therefore ad ised, particularly in the presence of small parts to count, to
always use the central part of the area.
- At the end of installation, check the
pieces to count always fall by crossing
the reading area.
- To a oid malfunctions, a oid
installation under direct sunlight or
stroboscopic lights.
- Do not install too tilted to a oid dust
build-up on the reading glass.

7 - Elect ical connections
Connect the connector and fasten it with the rele ant screws.
If possible, connect the support to an electrical ground.
The power supply should be connected on pins 1 and 2 which should be between 10 and
30V direct or between 12 and 18 V alternating. You are ad ised to use a "clean" power
supply, i.e. a line where there are no relays or motors or solenoid al es assembled nearby
without anti-disturbance filters.
Pins 8 and 9 host the passage signalling output (Clock), which is opto-insulated. It can be
used as a PNP or NPN signal. This output can pilot a maximum load of 100mA at a
maximum oltage of 24Vdc.

Pins 4 and 5 host the equipment functions block output (Error), each with the same elec-
trical characteristics.
Pins 3 and 7 can be connected to a EIA/TIA 485 communication interface that allows the
de ice to be controlled remotely. Refer to the appropriate manual for instructions on how
to use this interface.
Pin 6 can be connected to a ground wire to increase resistance to electrical disturbances of
the equipment. The slee e of a shielded cable must not be used for this connection.
8 – CPO use
Once powered and ha ing waited a few seconds to enable the CPO to optimise reading,
the equipment starts to work and signals on output C and with the green light switching on
each passage of an object in the reading field.
The CPO can, within certain limits distinguish objects that pass through the reading field
and therefore a oid the count of undesired objects such as work waste.
Knob E considerably adjusts detection of small objects. Maximum sensiti ity is obtained
by adjusting the knob completely in an anti-clockwise direction. Turning the knob
clockwise reduces sensiti ity to detection of small objects.
Knob C adjusts the speed with which objects are detected. Maximum speed is obtained
with the knob completely turned anti-clockwise. Turn the knob clockwise to reduce the
detection speed, i.e. this requires the object occupying the reading field for a greater time
to be detected.
Example: The ertically falling pens must be counted, but the caps that came off should
not be counted.
In this case, the crossing surface, being the ertical pens, is narrow and is equal if not
lower than that of the caps and therefore the sensiti ity necessary to detect the pens is

similar to that for cap detection. Howe er, the pens are much longer than the caps and
therefore take more time to cross the reading field. Thanks to detection speed adjustment,
you can a oid the caps being counted.
If an object is blocked inside the reading zone, or the dirt blocks the lens, or the faults
pre ent the CPO from working properly, the error output and the red led acti ate by sig-
nalling the problem to the counting and control equipment and the system administrator.
This information and settings can also be read and modified remotely ia the EIA/TIA485
interface, allowing recipes to be stored for counting objects with different sizes. The
remote configuration is stored in the CPO. If needed, it is possible to delete the configu-
ration data remotely or by turning both the sensiti ity and speed potentiometers fully
clockwise.
9 – Configu ation
The communication and operation parameters are recorded inside the CPO, their modifi-
cation (if necessary) can be done directly through the external programming keyboard
(optional) or from a control de ice through the EIA/TIA 485 interface. Refer to the appro-
priate manual for the use of the CPO with remote control for instructions on a ailable pro-
gramming.
10 – Maintenance
The only maintenance required is periodic cleaning of the reading glass with a soft brush
to pre ent dust build-up. If the glass gets dirty with greasy or oily residue, it can be
cleaned with a damp cloth with some dry degreaser, among those that don't lea e residue.
Ne er use contact cleaning spray or oily products for cleaning.
10 – Disposal
Ne er dispose of as domestic waste, but process it as industrial waste.
