2 Product Description
2.1 General Description
The InPro 8300 RAMS is an optical device for monitoring product/water phase separation processes and for the continuous measurement of turbidity and colour in various wavelength ranges.
In process automation applications, the unit supplies the switching signal for product/water or prod­uct/product phase separation. When a range of products is manufactured, it allows clear identification of the different products.
8 parameters are registered about 5 times a second; using 4 different wavelengths, the transmitted light and the back-scattered light are measured. This method allows virtually all liquids to be monitored, in­dependently of their colour and turbidity.
2.2 Highlights
• Use of durable and lasting stable LEDs
• No cumbersome and expensive lamp replacement
• Excellent zero stability
• Configuration using a commercial PC or notebook
• Easy to retrofit to VARINLINE
®
access units or VARINLINE®sight glasses without the need of
welding work
• In parallel to processing the switching outputs and the analog output in the PLC, visualization via a separate PC is possible
• A PC can be connected to record measured data
• Product identification can be displayed in table or chart form
• Easy copying of data into Excel
• An additional mA signal can be connected for product identification together with the 8 InPro 8300 RAMS parameters.
• Monitoring of fine turbidity and colour using one single unit
• Automatic self-monitoring if there is a risk of condensation forming on the optical windows
• Sapphire windows available as an option
• High temperature version available as an option

2.3 InPro 8300 RAMS types
InPro 8300 RAMS TCS Turbidity or Colour InPro 8300 RAMS optimized for phase separation. A jumper is used to determine whether the unit is
used for turbid or clear or coloured products. It works as absorption monitor
. The InPro 8300 RAMS TCS does not have any reflection parameters (see separate brochure). Unlike all the other InPro 8300 RAMS types, the InPro 8300 RAMS TCS does not have an additional communication interface, but only a 4–20mA analog output.
InPro 8300 RAMS BASIC Basic version of the InPro 8300 RAMS. It is mainly used for product monitoring, product identification and phase separation. It is used where
turbid, clear or coloured products flow through one and the same pipe.
InPro 8300 RAMS CALI InPro 8300 RAMS suitable for calibration. Up to 3 calibration curves can be implemented with the InPro 8300 RAMS CALI. This enables you e.g.
to continuously measure the turbidity and colour of different products at the same time. Exter
nal digi-
tal signals are used to switch between these measurements.
InPro 8300 RAMS COMBINE InPro 8300 RAMS suitable for calibration with special functions: – Used to measure low turbidities e.g. in water supply systems or in swimming baths. – In the brewery it is used for turbidity measurements at the lauter tun and supplies results that are
compliant with MEBAK guidelines.
– Apart from turbidity
, the product can also be monitored for colour changes, e.g. for SAC (436nm)
in water supply systems.
– Calculation of the yeast cell count in yeast pitching control
2.4 Measuring Cell
A VARINLINE®in-line access unit or VARINLINE®sight glass is used as a measuring cell. If fittings are already installed on site, the InPro 8300 RAMS is easy to retrofit without the need of welding work.

Relative humidity in %, measured in the electronics housing on the connection side near the window;
the colour of the display window changes and an alarm is triggered if the values
exceed 15%. Serial number of the InPro 8300 RAMS Firmware informs about the release status of the internal InPro 8300 RAMS software. Processor shows the software installed in the InPro 8300 RAMS:
00.00 = BASIC – used for phase separation, as limit value switch for turbidity or
colour and for product identification.
00.41 = CALI – for the continuous measurement of turbidity and/or colour
00.47 = COMBINE – for the continuous measurement of turbidity (also fine
turbidity) and/or colour
, used in special applications. Digital or analog operating mode mA output connected to which parameter
The connection status is displayed for all read and write operations. When a transmission error occurs when writing or reading data, this is indicated in the text field under Connection status.
Change-over
Here you can toggle between BASIC and CALI or between BASIC and COMBINE (not possible on InPro 8300 RAMS BASIC).
Calibration 1/2/3
This takes you to the InPro 8300 RAMS calibration mode. See section 6.
Correct
A new window opens where the InPro 8300 RAMS calibration can be adjusted to the results obtained in the plant laboratory (function not included on InPro 8300 RAMS BASIC).
5.4 Operating Mode
The InPro 8300 RAMS has 2 operating modes:
• Digital
• Analog
5.4.1 Analog operating mode
Use
Preferably when different InPro 8300 RAMS parameters are to be monitored by an external control system
• For signalling phase interfaces. Limit values are generated by the plant control system.
• Units of the InPro 8300 RAMS CALI or COMBINE type generally operate in the analog mode.

In analog mode, the digital signals are used as inputs to the InPro 8300 RAMS in order to connect an
external parameter to the mA output. The signals must be wired accordingly. Digital outputs must be provided in the external control system for this purpose (see Electrical connection). Rash change-over
can cause damage to the external control unit! For details about wiring see page 13.
5.4.2 Digital operating mode
Upon program start and when a new project is created, analog operating mode is set by default. If you wish to use the device in digital mode you can achieve this by clicking the ’Change-over
’ button and confirming your selection by clicking ’Yes’ in the message box that opens. If you click ’No’ in the message box, the system remains in analog mode.
Use
• For the identification of up to 8 different products which flow through the same pipe.
• For quality monitoring of products and to signal deviations from the tolerance.
• For signalling of phase interfaces between products with different turbidities or between clear or
coloured products.
The digital signals are used as InPro 8300 RAMS outputs here. The signals must be wired accordingly. Digital inputs must be provided in the external control system for this purpose. Rash change-over can cause damage to the external control unit! For details about wiring see page 13.
5.5 Zero Adjustment
Zero adjustment should be carried out after certain periods of time (approx. once a year). The reference for all parameters is water! Before carrying out a zero adjustment, make sure that clean,
bubble-free water is flowing through the pipe.
5.5.1 Procedure Adjustment without a connected PC
By pressing the red button for approx. 5 seconds. This sets the values for the concentration parame­ters to 400 and the values for the reflection parameters to 1000.
Adjustment when a PC is connected
When you have made sure that bubble-free, clean water is running through the pipe, that your PC is connected to the InPro 8300 RAMS and that you have started RAMS CONFIG, click “Read measured va­lues”. If the measured values for the concentration parameters deviate too much from 400 or if the reflection parameters deviate too much from 1000, click “Set zero point”.

Possible problems when setting the zero point
Should a value of 296 be displayed for one or several of the parameters, one reason for this may be that the water does not meet the a/m requirements. It is essential that the water is clean and without any bubbles to ensure stable conditions for setting the zero point and to ensure that the measured va­lues do not fluctuate.
If these results are obtained despite a good water quality
, the relevant parameters cannot be used. You should then check e.g. whether relative humidity is below 15%, as condensation may otherwise ha­ve been formed on the optical windows. Another reason could also be that the windows are dirty.
Repeat zero point setting if necessary.
6. InPro 8300 RAMS CALI/RAMS COMBINE – Suitable for Calibration
Instruments with the processor designation 00.41, 00.47 and 12.41 can be calibrated to a turbidity or colour unit. When the program starts up and a InPro 8300 RAMS is connected, this instrument op­tion is automatically identified. When the CALI function is used, InPro 8300 RAMS analog mode is activated.
After switch-over, the InPro 8300 RAMS CALI (or COMBINE) can also be used as InPro 8300 RAMS BASIC in digital mode. However, this is not possible vice-versa.
Meaning of display fields and function of the operating elements
• Calculated value 1/2/3 – The InPro 8300 RAMS can record up to 3 calibration curves. This
means it can be used for the continuous measurement of turbidity and colour at the same time.
Calibrated RAMS units – Display range 400…2000 corresponding to 4– 20mA in proportion to the measuring range
• Start of measuring range – Zero point of the calibration
• End of measuring range – End point of the calibration
• Calibrated measuring value – Measuring value in the physical unit
• Unit – physical unit in which calibration was made
• Parameters – The RAMS parameter used for the calibration
• Correct – To adjust the InPro 8300 RAMS measured values to the values obtained in the
laboratory
• Calibration 1/2/3 – To access calibration mode
The InPro 8300 RAMS is calibrated at the factory before delivery. If it turns out that the unit requires re­calibration for another measuring range, the manufacturer will supply a file which is loaded into the InPro 8300 RAMS configuration from where it is transferred to the InPro 8300 RAMS.
Procedure
• Copy the file you have obtained into the directory “RAMS_Projekte” of drive C.
• Start RAMS CONFIG.
• Click “Load” in the “File” menu and select the file with the same name as the InPro 8300 RAMS’s
serial number.
• After a few seconds, a message box is displayed which asks you whether the new data should
now be transferred to the InPro 8300 RAMS. Click “Y
es” to finish the process. The InPro 8300
RAMS has now been recalibrated.

Correcting the Calibration
If there are any deviations between measurements made in the plant laboratory and the results produ­ced by the InPro 8300 RAMS, the calibration can be corrected.
Procedure
• To do so, click the relevant “Correct” button in the “RAMS Configuration” screen for the parameter for
which deviations have been detected.
Enter the relevant values in the “RAMS” and “Laboratory value” fields.
• Decide on the type of correction and click the corresponding button.
Type of correction
• Correction of the entire curve – is used to obtain the same change in terms of percentage for the
entire range to be displayed. This function should only be executed once at the beginning of the correction. When several products are produced, differ
ent deviations can occur. These should then
be eliminated by carrying out a partial correction.
• Partial correction – is used to eliminate the deviations relating to different products in the part of the
measuring range in which the measuring values of these products occur.
• Parallel displacement – Is used to shift the calibration curve by an absolute amount; it can also be
shifted through the zero point. It is preferably used for measuring ranges where the zero point of the calibration does not start with the water value (400 for the concentration parameters or 1000 for the reflection parameters), but on a higher colour or turbidity level.

7 Yeast Pitching
Function
InPro 8300 RAMS 1 = InPro 8300 RAMS CALI – Instrument with the lower serial number
Measures the basic turbidity of the wort in the measuring range 0…1000 EBC and transfers the result to the parameter “Calculated value 1”.
InPro 8300 RAMS 2 = InPro 8300 RAMS BASIC or InPro 8300 RAMS TCS
Monitors “yeast draw-off” so that metering can only be started when yeast has arrived at the metering point.
Commissioning procedure
• Before commissioning using wort and yeast, the zero points of all units must be adjusted to water.
When wort (without yeast) runs through the pipe, the turbidity values measured by the two InPro 8300 RAMS units must be identical. If the measured values deviate, one of the two units mus be adjusted using the RAMS CONFIG program.
• This correction must be repeated if necessary.
• While yeast is being added, the measured values for the yeast cell count obtained by InPro 8300
RAMS 2 must be verified in the laboratory. Several tests in the laboratory are advisable. If the deviation is detected several times, the measured value also needs to be corrected.
• If different setpoints are used for different types of beer, the measuring results should be checked in the laboratory for each of these setpoints and the values corrected if necessary.

Electrical connection of the InPro 8300 RAMS units
InPro 8300 RAMS 1 is the unit upstream of the metering point InPro 8300 RAMS 2 is the unit downstream of the metering point M+/M- are connections for the uninterruptible measurement of the output currents of the InPro 8300
RAMS units. The outputs are non-floating and are measured against L-. The 4–20 mA output for the yeast cell count is available at terminal 20 of the connection module. The PC can be connected to the socket of the connection module. By toggling the switch you can switch
between the communication with InPro 8300 RAMS 1 and InPro 8300 RAMS 2. Before switch-over always end the program, after switch-over restart the pr
ogram, since otherwise the calibration files in the RAMS_Projekte folders might be overwritten. Should this happen, you will find a backup in the folder c:\RAMS_Projekte\Factory which you can copy to c:\RAMS_Projekte.
