WARNING

• CANNOT be used as a normal counter available from the trade.
  It has not been designed and approved for use as a legal metrology instrument.

• DO NOT use gases other than those specified; measurement accuracy is not guaranteed and the device may get damaged.

• Do not use it outside the stated specifications.

• The compressed air from the compressor contains impurities (water, oil, dirt or other residues), which may affect accuracy or damage the sensor. Make sure that the air  supplied to the FLUX is properly filtered and has a minimum purity level of 4.7.3, in accordance with ISO 8573-1.

• Do not use with lubricated air.

• Do not insert foreign objects into the connection ports.

INSTALLATION

1.1 PNEUMATIC CONNECTION
Pneumatic connection is via the threaded holes in the body.

• Install the device following the arrow indicating the direction of the air flow.
• To connect the inlet side, use a straight pipe* at least 150 mm-long for FLUX 1 and at least 200 mm-long for FLUX 2.
  If straight piping is not installed, the accuracy may vary from what is stated.
• Straight pipe: the pipe must be straight with a constant cross-section.

• Clean the pipes before installation, uncleaned air may cause malfunctions or damages to the product.
• Make sure that the sealant does not get inside the pipe. Solid or liquid residues could damage the sensor.

When air flow needs to be regulated with a control valve; install the device upstream of the valve.
Otherwise, grease or lubricating oil from the valve could damage the sensor.

• The device can be installed in any direction.

1.2 INTEGRATION WITH COMPONENTS IN THE Syntesi® PRODUCT RANGE
FLUX can be supplemented with Syntesi® component parts:

• FLUX 1 with Syntesi® size 1;
• FLUX 2 with Syntesi® size 2.
  In order to guarantee the stated measurement accuracy and to prevent lubricant residues from damaging the measurement sensor, a filter has to be mounted at the FLUX inlet.
  If the device is fitted with a Syntesi® filter, the SYN filter parameter must be enabled in the system menu to guarantee the stated accuracy (function available only for the version with display).

N.B.: If the FLUX is used downstream a Syntesi® filter, fit it in one of the three positions shown in the figure.

1.3 ELECTRICAL CONNECTION
A 5-pin M12 Code A connector is used for the electrical connection
M12 male connector, A encoding

WARNING
Switch off the mains supply before plugging or unplugging the connector (functional damage hazard).
WARNING
Keep the connecting cable separate from the power cables. The device may not work properly due to electromagnetic interference, strong currents or high voltage.

3.1 SYSTEM
The compressed air system is connected through the threaded holes on the body.
In order to prevent impurities or excessive condensation from causing malfunctions, it is recommended to supply the FLUX with dry 20μm-filtered compressed air at a  pressure not exceeding 10 bar.
3.1.1 SYN filter
Set to ON when the FLUX is installed after a Syntesi unit filter to optimise flow rate reading.
3.1.2 Gas type
Helps optimise the measurement of the current flow and consumption figures.
Types of gas: Air
Helium
CO2
Nitrogen

3.1.3 K ENERGY
K-Energy is the amount of Wh consumed to generate 1 Nm³ of compressed air, depending on the efficiency of the production system.
Used to calculate the current power (kW) and accumulated energy (kWh) consumption.
