SYCON 2802 en L

Summary

Product identification

The SYCON 2802 is an online analyzer based on the SYCON series, utilizing the colorimetric titration method for automatic determination of water parameters. It can determine one parameter at a time, with the specific parameter and measuring range dependent on the indicator used.

• Analogue output: 0 – 20 mA / 4 – 20 mA (Resolution: < 100 μA, Max. load: 750 Ω).
• RS-485: Modbus RTU protocol.

Maintenance intervals

• Every 6 months: Cleaning the measuring chamber. Intervals may need shortening with high ambient/water temperatures or high organic matter.
• Every 30,000 analyses or after 2 years of operation: Cleaning the measuring chamber, installation of maintenance kit (peristaltic pump cartridge and seals replacement), and resetting the maintenance counter.

Indicators for monitoring total hardness

See the official PDF for exact tabulated values. Available units for analysis value include: °dH, °f, ppm CaCO₃, mmol/l, °e, °Ж.

Indicators for monitoring carbonate hardness

See the official PDF for exact tabulated values. Available units for analysis value include: °dH, mmol/l, °f.

Note: The measured value should be close to the middle of the indicator's measuring range. One bottle of indicator is sufficient for approx. 10,000 analyses in the lower range of the indicator type.

Mounting

The SYCON 2802 must be installed upright.

• Without housing: Wall bracket has four 6 mm holes.
• With housing: Supplied with 4 mounting brackets with 6.5 mm holes. Required space for opening: at least 450 x 350 mm (W x H).

Connections:

• A: Cable glands for electrical connection
• B: Water inlet connection (hose with 6 mm outer diameter)
• C: Water drain connection (hose with 6 mm outer diameter)
