Fig. 6: Side mounting with 8-point magnetic holder stabilizing element Magnet Magnet release device Locking lever Mounting plate with screws Fig.
Page 19 Setup and Connection Mount the stabilizing element on the magnetic plate holder. Take the pre-assembled magnetic plate holder and place it parallel to the vehicle body (e.g. on the passenger door as shown on the left). The magnetic plates will automatically adhere to the (metal) vehicle door/body panel.

No. 18012595 CSF2A_002-582e-12.16 Page 19...
Page 22 ® Correvit Non-Contact Optical Sensors, Type CSF2A... To assure proper functioning of the suction holders, the mounting area must be free of grease, oil, dust and other contaminants. For this reason it is necessary to clean the painted surface in the mounting area before attaching the suction holders.
Page 23 Setup and Connection When the suction holder unit is correctly positioned, press the suction holders – one after the other – ﬁ rmly against the vehicle body to ﬂ atten the rubber pads against the body surface. Then, push the two pumping pistons repeatedly until the red warning ring is not visible any more.
Page 24: Installing The Safety Line

Page 28 ® Correvit Non-Contact Optical Sensors, Type CSF2A... Slip the protective boots over the lower and upper sections of the torsion rod. Then, ﬁ t the upper section of the torsion rod into the joiner at the top of the lower section of the torsion rod.
Page 29 Setup and Connection Loosen the sensor mounting retainer set screw with an allen wrench. Place the SF wheel mounting plate onto the mounting hub and re-tighten the set-screw. Insert the included sensor mounting screws through the mounting holes in the sensor, then into the mounting holes in the mounting plate and tighten the screws.
Page 30 If desired, mount the optional heat sink onto the sensor head using an allen wrench. Fig. 32: SFII wheel mounting, step 9 Now, your Correvit SFII sensor is ready for use! To avoid temperature drifts of the electronics during the measurement, we recommend that you switch on the sensor 15 minutes before you start the measurement.
Page 31: Connecting The Sensor
Setup and Connection 5.4 Connecting the Sensor to power supply CAN/RS-232C interface analog/digital output to sensor Fig. 33: SFII electronics, front plate connectors The electronics unit is equipped with reverse polarity protection. In the event that polarity is inverted, the unit will not be damaged (the power LED is illuminated red).
Page 32 ® Correvit Non-Contact Optical Sensors, Type CSF2A...  Connect the electronics to a power distribution unit.  Start the vehicle engine and connect the power distri- bution unit to the vehicle power supply.  Switch the distribution box power circuit on to send power to the sensor electronics.
Page 33: Sensor Settings
For conﬁ guration and calibration of the sensor you need the KiCenter software. You will ﬁ nd this software on the delivered CD or at www.kistler.com. To link KiCenter with the sensor, you must connect it to a PC using the RS-232C cable or the USB adapter.

Fig. 39: Screen view of the SFII "CAN Bus" page Baud Rate Rate of transmission of the CAN bus protocol. Must cor- respond to the data acquisition system setting.
Page 41 Sensor Settings The sensor internally always works with an interval time of 4 ms. If you increase the send interval, not every mea- surement value will be output via the CAN bus. In this case, we therefore recommend activating a ﬁ lter with an appropriate average mean value time.
Page 42 ® Correvit Non-Contact Optical Sensors, Type CSF2A... Create CAN DB KiCenter provides the option to create CAN database ﬁ les (CAN DB). Only the status page provides the option for generating CAN DB ﬁ les. Please click the "Create CAN DB" button in the tool bar. Fig.

Page 47: Troubleshooting
Troubleshooting 7. Troubleshooting 7.1 Cables and power supply  Check all connections to determine that each is complete and that the system is connected to a power supply that provides voltage output within the speciﬁ ed range.  Check to determine that the correct cables have been used for all connections.
Page 48: Sensor Lens (Protection Glass)
® Correvit Non-Contact Optical Sensors, Type CSF2A... 7.4 Sensor Lens (Protection Glass) The sensor lens or protection glass (if there is any) may occasionally become dirty, preventing proper operation. Check and clean the sensor lens or protection glass regularly. 7.5 Operating range If the sensor is mounted out of the recommended height range (standoff distance), no measurement signals will be output.
