3. Intended use
The converter is exclusively to be used as a converter for Spirax Sarco sensor assemblies
according to the technical data.
In combination with inline sensors for turbidity, the converter is used for displaying and
processing measuring results.
The converter is only applicable for sensors listed in Section 6 'Technical data'.
The converter is to be installed in a control cabinet, which provides an external release
device so that the converter can be switched voltage-free. Reference Section 6 'Technical
data'.
The use in explosion proof areas is prohibited.
Unauthorized constructional changes, additional fittings or rebuildings as well as changes
to and interference with the converter program are prohibited.
The manufacturer is not liable for damage resulting from use contrary to intended use.
Following these Installation and Maintenance Instructions is part of the intended use.
The content of all serial number plates on Spirax Sarco products is model specific and
refers to the time of delivery.

4. Safety
4.1 General safety instructions
Only operate the converter when free from defects and in accordance with the instructions
provided in this manual.
Read this instruction manual prior to initial commissioning. This applies especially to persons
only operating the converter occasionally, such as maintenance staff.
Observe all safety and information labels on the product and keep them in readable
condition.
Inspect the product for signs of physical damage. Report any damage immediately and do
not commission the product until corrective actions have been taken.
After maintenance and repair, proper function as well as the fulfillment of the safety
requirements and testing must be guaranteed.
Protect the converter from impacts causing corrosion or preventing components from
working properly.
Have faulty parts of the measuring system replaced immediately.
Spare parts must comply with the technical requirements defined by Spirax Sarco. This is
always guaranteed when using original spare parts.
For maintenance and repair activities, attach a warning sign to the external release device
to prevent re-commissioning of the converter.
When malfunctioning, take the product out of operation. Have the malfunctions repaired
immediately by a qualified electrician.
The safety instructions are to be supplemented with the current National regulations on
accident prevention.

4.2 Safety instructions for works on electrical equipment
Work on electrical equipment has to be carried out by qualified electricians only. The power
line connection of the converter must be specified correctly to prevent overload.
Disconnect the voltage supply before connecting the power line. Only connect the power
line when voltage-free. Do not use the terminal socket for release since no first-to-mate
last-to-break protective ground contact is provided.
Do not work on live active parts of the electrical equipment. When working on the electrical
equipment, observe the following safety regulations:
1. Switch voltage-free.
2. Protect against re-commissioning.
3. Check if voltage-free.
4. Cover live parts.
5. Earth and short-circuit.
In case of faults in the power supply, disconnect the converter immediately. In case of a
short-circuit, there is a danger of sparking and fire.
Use only original fuses with specified current and triggering characteristics! When a fuse has
to be exchanged, first try to detect the cause and clear the fault before exchanging the fuse.
When work on live parts is necessary, use insulated tools only.

5. Description of the converter
The Model 556 converter is a universal device designed for process monitoring and control
of a Spirax Sarco sensor assembly.
Fig. 1 Model 556 converter
In the converter, both the direct light and the scattered light signal are boosted and a
weighted proportional value is obtained. The thus created measurand is proportional to
the total volume of particles in the medium. The Model 556 provides four defined and one
variable measuring range to be adjusted to your specific process parameters. The LED
indicator indicates the percentage of the selected measuring range.
For connection to the process control system, the Model 556 converter is equipped with two
independent setpoints and a 4 - 20 mA-output for alarms and real-time process monitoring.
An additional relay output (failsafe) gives alarm in case of lamp or power failure. In a
standardized manner, basic system calibration is carried out in ppm DE (mg of diatomaceous
earth / l of water). If desired, calibration in FTU (Formazin Turbidity Standard) or EBC
(European Brewery Convention) is possible as well.
The converter complies with the highest security standards. The device complies with the
requirements of the EMC Directive in accordance with .
