General information
2.2 Product overview
The FP 360 sc sensor is a UV fluorimeter used to continuously measure the concentration
of PAH (polycyclic aromatic hydrocarbons) in water. The measurement values can be
converted to reflect the total oil content for mineral oils using lab data.
The sensor may need to be installed with additional accessories depending on its area of
application.
Do not apply the sensor to any hard mechanical effects.
2.3 Measuring principle
The measuring principle is based on the fluorescent properties of PAHs. After excitation
caused by UV rays, PAHs emit light with longer wavelengths after a short time delay. The
intensity of this light is measured. This measuring principle is considerably more sensitive
than absorption and scattered light measurement. It is possible to detect even the slightest
trace of PAH contamination in water. PAHs are integral parts of most mineral oil products
and are a very specific indicator of oil contamination in water bodies and process water.
2.4 Product components
Each sensor is supplied with
•a connector cable with safety sleeve,
•a shackle,
•a basic user manual and
•a CD.
The sensor is available in a variety of types (refer to section 7.1 on page 27). Refer to
Figure 2 to make sure that all components have been received. If any of these items are
missing or damaged, contact the manufacturer or a sales representative immediately.
DANGER
This product is not suitable for use in potentially explosive atmospheres.
WARNING
The UV rays from the flash bulb are harmful to eyes and skin. Do not look directly through the
measurement window during operation under any circumstances. Remove the measurement
sensor from operation before carrying out any maintenance or installation work.

2.5 Function test
After the components are removed from the package, do a function test.
1. Connect the connector cable to the sensor (8-pin polarized connector) and an
appropriate sc controller (5-pin polarized connector) (refer to section 3.1 on page 11).
2. Apply power to the sc controller. The display is activated and the sensor goes to
measurement mode.
The sensor ticks quietly and regularly.
CAUTION
Before power is applied, refer to the controller operation instructions.

General information
3. Cover the sensor measurement window with a sheet of white paper (do not use
recycled paper).
4. Vary the distance between the measurement window and the paper. 
The measurement value on the display will change accordingly.
Note: In air, the measurement value displayed is not exactly zero due to reflections on the window
surface (refer to section 4.5.3 on page 21).

Section 3Installation
3.1 Connect sensor cable
1. Connect the polarized socket on the connector cable to the sensor plug (8-pin plug)
(refer to Figure 3 step 1).
2. Push the safety sleeve on the plug (step 2).
3. Hand-tighten the safety sleeve in position (step 3).
Figure 3 Connect the sensor cable to the sensor
4. Remove the protective cap on the controller socket and keep it to seal the connector
opening in case the sensor must be removed.
5. Connect the sensor to the controller using the keyed quick-connect fitting.
Hand-tighten (refer to Figure 4).
Note: Connector cables are available in various lengths (refer to section 7.2 on page 27). Maximum
overall cable length is 40 m (131,23 ft).
DANGER
Personal injury hazard. Only qualified personnel should conduct the tasks described in this section
of the manual.
NOTICE
If the sensor is not fully inserted, sun protection is recommended in high ambient temperatures
and intense solar radiation to protect against thermal and UV effects.
CAUTION
Always put the cables and hoses in a position that does not bend or cause a trip hazard.
CAUTION
Before power is applied, refer to the controller operation instructions.

Operation
4.5 Calibration
4.5.1 Factory calibration
The calibration curve zero point and slope are preset. Retrospective calibration of these
basic settings is generally not required outside of the inspection intervals.
Do regular zero point checks to make sure that impurities or faults are being detected
(refer to section 4.5.3 on page 21).
If the zero signal increases due to the measuring medium components or the installation
conditions, you can compensate for this influence via an offset correction. Carry out a lab
analysis of the sample to do this. If there is no PAH/oil contamination in the measuring
medium, enter the measurement value shown by the device as the offset (refer to section
4.5.4.2 on page 22).
4.5.2 Process calibration/adjustment
The sensor is pre-calibrated with various concentrations of a special calibration standard
in ultra-pure water. These ideal measurement conditions rarely occur in reality. The
measurement values shown are qualitative trend indicators if no adjustment is made to the
on-site measurement conditions.
If you require quantitatively correct measurement values, either a slope adjustment or a
multi-point calibration needs to be carried out. Both of these operations must be carried
out on site using lab analysis data. Basic prerequisites for quantitative measurements are
precise knowledge about the oil type in occurrence and constant measurement conditions,
e.g. in cool water in a heat exchanger. If several oils are present in varying quantities, it is
generally not possible to carry out a quantitative measurement.
If the measurement conditions change, you must check the accuracy of the results again
through lab analyses and make any adjustments where necessary.
The measurement conditions can change in terms of
• Composition of PAH or oil impurities
• Distribution of impurities in water
• Temp
• Measuring medium composition
• Measurement sensor and measurement window
4.5.2.1 Determination of factors and adjustment of slope
To adjust the slope:
1. At the sensor installation site, draw a lab sample of the measuring medium and
promptly analyze the sample for PAH and oil content.
2. Make a note of the measurement value shown on the controller at the time of the
sample being taken. Make sure the correct unit is shown for the measurement value,
e.g. as ppm oil.
3. Repeat steps 1 and 2 several times.
4. Use the sample value and the value shown on the controller at the time of sampling
to calculate a factor.
5. Find an average value from the factors.
