Product Description
4 Product Description
4.1 Use and Application
The PCV read head is part of the positioning system in the Pepperl+Fuchs incident light
process. Its features include a camera module and an integrated illumination unit, enabling it to
detect position markers printed onto an adhesive code reel in the form of Data Matrix codes.
The code reel is usually mounted to a fixed part of the equipment in a stationary manner (e.g.,
elevator shaft, overhead conveyor mounting rails) and the read head is then mounted in parallel
to a moving "vehicle" (e.g., elevator car, overhead conveyor chassis).
Maximum Length of the Code Reel
This positioning system can be used with an appropriate resolution in equipment with
extremely large layouts without restrictions.
The extensive yet user-friendly parameterization options as well as the freely configurable
inputs and outputs mean that the read head can easily be adapted to suit each application.
4.2 The RS 485 interface
The reading head is equipped with an RS 485 interface for communication purposes, i.e.
parameterizing the reading head functions or reading out current process data during
operation. This interface is operated in 8- -1 mode and fitted with a terminator that can be
activated or deactivated by parameterizing the sensor head accordingly. The RS 485 interface
supports the following transfer rates:
■ 38400 bit/s
■ 57600 bit/s
■ 76800 bit/s
■ 115200 bit/s(Default)
■ 230400 bit/s
Data structure of the RS 485 interface
4.3 L D indicators and controls
The PCV... reading head is equipped with 7 indicator L Ds for performing visual function
checks and rapid diagnosis. For activating the alignment aid see chapter 6.1 and programming
mode, see chapter 6.2 two buttons are provided on the back of the reading head. ADJUST

5 Installation
5.1 Installing the Code Reel
The code reel is made of silicone-free polyester film. A position marker appears every 100 mm
along the lower edge of the code reel (see "Dimensions, Code Reel"). This position marker is
used for various functions including precise positioning of the code reel during assembly.
The reverse side of the code reel carries a permanent modified acrylate-based adhesive. Affix
the self-adhesive code reel along the desired travel range. Proceed as follows:
Installing the Code Reel
1. Clean the surface of any greasy or oily deposits and dust.
2. nsure that the surface is dry, clean, and stable.
3. Pull the protective foil at the beginning of the code reel a few centimeters forward. Place the
code reel at the precise point of the required starting position on the underside, and press to
attach.
4. Then affix the code reel along the desired travel range. Remove the protective film gradually
so that the code reel does not accidentally adhere to the surface in the incorrect position.
When affixing, ensure that the code reel does not crease or trap air bubbles.
The adhesive on the code reel hardens after 72 hours.

Connector Assignment
Color Assignment
Pepperl+Fuchs single-ended cordsets (female) are manufactured in accordance with
N60947-5-2. When using a type V19-... (see chapter 4.4) single-ended cordset (female) with
an open cable end, colors are assigned as follows:
Shielding Cables
The shielding of connection lines is required to suppress electromagnetic interference.
stablishing a low resistance or low impedance connection with the conductor or equipotential
bonding circuit is a particularly important factor in ensuring that these interference currents do
not become a source of interference themselves. Always use connection lines with braided
shield; never use connection lines with a film shield. The shield is integrated at both ends, i.e.,
in the switch cabinet or on the controller and on the read head. The grounding terminal
available as an accessory allows easy integration in the equipotential bonding circuit.
In exceptional cases, the shielding of a connection at one end may be more favorable if
■ An equipotential bonding cable is not laid or cannot be laid.
■ A film shield is used.
The following points relating to shielding must also be noted:
■ Use metal cable clips that cover large areas of the shield.
■ After installing the cable shield in the control cabinet, place it directly on the equipotential
bonding rail.
■ Direct the protective grounding connections to a common point in a star configuration.
■ The cross-section of the cables used for grounding should be as large as possible.

6.1 Aligning the Read Head
An integrated alignment aid is available to help you align the Y and Z coordinates of the read
head easily and precisely with respect to the code reel.
The switchover from normal operation to parameterization mode is via button 1 on the back of
the read head.
Activating the Alignment Aid
1. Press button 1 for longer than 2 seconds.
L D2 flashes green for a recognized code reel. L D2 flashes red for an unrecognized
code reel. see chapter 4.3.
2. Align the Z and Y coordinates of the read head. The integral L D indicators provide
assistance here.
Z coordinate: If the distance of the camera to the code reel is too small, the yellow L D5 lights
up. If the distance is too great, the yellow L D5 goes out. The yellow L D5 flashes at the same
time as the green L D2 when within the target range. See chapter 4.3.
Set the distance between the read head and the code reel so that the yellow L D5 and the
green L D2 flash synchronously.
coordinate: If the optical axis of the read head is too low relative to the middle of the code
reel, the yellow L D4 lights up, see chapter 4.3. If the optical axis is too high, the yellow L D4
goes out. Within the target range, the yellow L D4 flashes at the same time as the green L D2.
Set the optimal height of the read head relative to the code reel so that the yellow L D4 flashes
in rhythm with the green L D2.
Briefly pressing button 1 ends the alignment aid, and the read head returns to normal
operation.
6.2 Parameter assignment
The reading head can be adapted to specific requirements through parameterization. The
reading head can be parameterized via the interface itself (internal parameterization) or via an
optical parameterization code (external parameterization).
6.2.1 Internal Parameterization Using Parameterization Software
Internal parameterization of the reader via the RS485 interface must be started within ten
minutes of the reader being switched on. A time lock disables the reader once this time has
elapsed. The time lock remains inactive during the parameterization process. The time lock
disables the reader if no parameterization activity takes place for more than ten minutes.
Note!
The activation of the alignment aid is possible only within 10 minutes of switching on the read
head.

Commissioning
For best results when performing comprehensive parameterization tasks, the user-friendly
PCV/PGV Parameterization Tool is a handy aid. This parameterization software for the PC is
available as a free download from www.pepperl-fuchs.com. Follow the instructions that appear
on your screen during the installation.
If your PC does not have a built-in RS485 interface, you will need a USB/RS485 interface
adapter; see the "Accessories" chapter.
Parameterizing the Reader
1. Connect the reader to your PC via the interface adapter. Information on how to do this can
be found in the manual for the interface adapter.
2. Connect the reader to a suitable power supply.
3. Switch on the power supply.
4. Start the parameterization software.
5. Parameterize the reader with the aid of the manual for this parameterization software.
6. Transfer the list of parameters to the reader.
7. Save the parameterization.
8. Switch off the power supply on the reader.
9. Disconnect the reader from the interface adapter and from the power supply.
The reader is parameterized according to your specifications and can be used in your
application.
6.2.2 xternal Parameterization using Code Cards
During external parameterization, the read head scans the special code cards optically and
configures the relevant parameters. Simply hold the corresponding code cards at the correct
distance in front of the lens on the PCV...-F200- read head. see chapter 8.1.
The following parameters can be configured using code cards:
■ Read head resolution [0.1 mm, 1 mm, 10 mm]
■ Orientation of the read head [0°; 180°; 0° or 180°, 0°, 90°, 180° or 270°]
■ Trigger source [auto, hardware]
■ Function of input 1 [none, trigger input]
■ Function of output 1 [None, overspeed, warning, error, dirt, event, no position]
■ Function of output 2 [None, overspeed, warning, error, dirt, event, no position]
■ Function of output 3 [None, overspeed, warning, error, dirt, event, no position]
Activation of programming mode
The switchover from normal operation to parameterization mode is via button 2 on the back of
the read head.
Note!
xternal parameterization of the read head using code cards must be started within 10 minutes
of the read head switching on. A time lock disables the read head when this time has elapsed.
The time lock remains inactive for the duration of the parameterization process. If no
parameterization activities take place for more than 10 minutes, the time lock disables the read
head.
If a button is pressed when the time lock is enabled, all L Ds flash and remain lit for 2 seconds
during each flashing cycle.
