2.3 Proper Use
The LCI sensor is designed for the use in industrial areas. The sensor is used for optical
measurements, such as 3D topography, dimensions and distances measurements,
measuring the tomography of transparent materials, surface micro profile
measurements, and film thickness measurements.
Only use the sensor in such a way that, in the case of malfunction or failure, personnel
or machinery are not endangered.
Ambient temperature range: +15 ºC … +35 ºC.
2.4 CE Marking
FocalSpec Oy has confirmed that these products comply with the essential
requirements of the applicable EC Directive, based on the following specifications.

5Connecting to PC
10 Gbit connection with SFP+ interface is needed to enable the high-speed data
transmission.
The recommended network adapter is Intel Ethernet Converged Network Adapter X520
either two port DA2 or four port DA4 model.
Figure 1. Example of two port Intel Ethernet Converged Network Adapter X520 DA2
Windows 10 64-bit is the recommended operating systems, but sensors work also with
Windows 7.
6Installation and Mounting
3D CAD STEP as well as high-resolution versions of the drawings below are included in
the USB drive folder “hardware”. The position and orientation of the optical profile is
shown in an enlarged detail image for each model. The X, Y, Z origin in each STEP file is
placed into the middle of the optical profile.

7Handling Optical Cable and SFP+ Modules
IMPORTANT – FRAGILE
Minimum bending radius of optical cable is 100 mm. Don’t bend
cable more than this. This applies to the whole length of the
cable and it is especially important to pay attention to computer
end of the cable as it is more flexible.
Never touch optical cable fiber ends with bare hands or let the
fiber ends touch anything else but cleaning equipment.
Never put anything inside the optical fiber slots of the SFP+
module.
7.1 General Instructions
1. When storing optical cables and SFP+ modules, make sure the protective caps are
attached.
2. When the cables and SFP+ modules are in use, store the protective caps in an
airtight plastic bag.
3. Never touch the cable ends with anything other than the cleaning cloth.
4. If a cleanroom is available, it’s recommended to install SFP+ modules to cable in
there.
5. Preferably wear cloth gloves when handling cable connectors.
6. Make sure the minimum bending radius of cable bend is about 100 mm (Figure 3).
Don’t let the cable bend more than this. This applies to the whole length of the cable
and it is especially important to pay attention to computer end of the cable as it is
more flexible.

7.2 Installing SFP+ Module and Optical Cable
Steps to install the optical cable and SFP+ module:
1. Remove protective plug from SFP+ module.
2. Remove protective caps from the other end of the optical cable. Be sure not to touch
the optical fiber ends with anything.
3. Push the lock handle down on the SFP+ module (step 1). This is the open position.
This is done because the SFP+ module might be used with some SFP+ slots which
.

have a lock. Having the lock readily in the open position enables quick and easy
attaching of the SFP+ module.
4. Carefully insert the cable connector to SFP+ module. Push the connector gently until
it locks in place (step 2). Usually there is an audible “click” when the connector locks
in place. Make sure the lock handle has remained in the open position.
5. Verify that connector is locked to the SFP+ module by pulling very gently on the
cable: it must not be loose (step 3). If it is loose and detaches from the SFP+ module,
repeat by pushing the connector to the SFP+ module until it locks into place.
6. Insert SFP+ module to the SFP+ card at PC (step 4). Make sure the SFP+ module is
positioned in the correct way.
◦CORRECT: There should be a slight resistance when pushing the SFP+ module
the correct way, as the connector in the SFP+ module slides into the connector at
SFP+ slot side. The SFP+ module should not come out very easily.
◦INCORRECT: If the SFP+ module is inserted in incorrect way, there is no
resistance. The SFP+ module slides out very easily.
7. Insert the quick connector of the optical cable to the sensor.
7.3 Detaching SFP+ Module from Optical Cable
Steps to detach SFP+ module from optical cable:
1. Press the lock tab down in optical cable connector (step 1).
2. Pull the cable out of SFP+ module (step 2).
3. Place protective caps on the optical cable connector and SFP+ module.

8Electrical Connections
LCI1220 and LCI1620 sensors are powered by using a PushPull type 4-pin cable with
Harting Power connector. For input signals which can be used for synchronization
purposes 10-pin PushPull type cables with Harting Signal Connectors is used. The
sensor communicates with PC via Optical cable with SFP+ 10G transceiver modules.

Figure 7. Electrical connections for LCI1620 (I/O 2 connector is not in-use at the
moment)
There are three indicator LEDs next to the connectors on the connector panel.
The status LED turns red if the sensor is not connected to a PC or a router. Blue means
SW is booting up, whereas a green light indicates that the connection is established. The
status LED blinks green when Ethernet packets are sent or received.
The position LED helps the user to find the correct distance to the target to measure. A
green light is shown when target is in the measurement range. A blue light is shown when
target is at the edge of the measurement range. A red light is shown when the sensor
detects ambient light. This can be caused by incorrect illumination settings.
Power LED indicates with green light that power is ON and supply voltage level is in
correct range. Red indicates that supply power is over the correct supply range and then
the device will not power up.
