SiBoost2.0 Smart 2HELIX VE407

Compact pressure-boosting system according to DIN 1988 and DIN EN 806, for direct or indirect connection. Consisting of non-self-priming, connected in parallel, vertically-mounted stainless steel high-pressure multistage centrifugal pumps in glanded versions, for which each pump is fitted with a variable frequency drive. Ready for connection with stainless steel pipework, mounted on a base frame, including control device with all necessary measurement and adjustment equipment.

• Fully automatic water distribution and boosting in residential, commercial and administrative buildings, hotels, hospitals, department stores and in the municipal water supply and industrial systems.

Pumping of

• Drinking water
• Process water
• Cooling water
• Firefighting water (apart from fire-fighting systems in accordance with DIN 14462 and with the approval of the local fire protection authorities) or other types of industrial water that do not corrode the materials either chemically or mechanically and do not contain abrasive or long-fibre constituents.

Special features/Product advantages

• Heavy-duty system that fulfils all the requirements of DIN 1988 (EN 806)
• WRAS/KTW/ACS approval of the pumps for all parts that come into contact with the fluid (EPDM version)
• Helix2.0 VE series high-efficiency pump hydraulics, combined with IE5 EC motor drives, with air-cooled integral variable frequency drives
• Pressure-variable (pv) control mode ensures optimum pump load adjustment and parallel synchronous speed control increases energy savings
• Disproportionately large variable frequency drive control range of 25 Hz up to a maximum of 60 Hz saves energy
• Integrated dry-running detection with automatic cut-out in event of low water via performance characteristics of the motor control electronics
• Bidirectional mechanical seals in the pumps for easy maintenance
• The flexible lantern design enables direct access to the mechanical seal
• Hydraulics of entire system are pressure-loss optimised
• Parts that come in contact with the fluid are corrosion-resistant
• SCe2.0 control device, maximum degree of control performance with colour graphics display, simple navigation with clear menu, and Green Button Technology for setting parameters to control electronic pumps with variable frequency drives
• Ready for integration into building automation with the SCe2.0 switchgear via standard-equipped Modbus TCP and BACnet IP (native), Modbus RTU and BACnet MS/TP via adapter from USB to RS485
• Factory testing and presetting to optimum working range

Equipment/function

• Helix2.0 VE2 to Helix2.0 VE52 series stainless steel high-pressure multistage centrifugal pump
• Base frame made of electrolytically galvanised steel, with height-adjustable vibration absorbers for insulation against structure-borne noise

On the discharge side:

• Shut-off valve at each pump
• Non-return valve at each pump
• Diaphragm pressure vessel 8 l, PN 16
• 2 pressure sensors 4 – 20 mA
• Pressure gauge
• Threaded cap or blind flange depending on the nominal diameter of the manifold

on the suction side:

• Shut-off valve at each pump
• 2 pressure sensors 4 – 20 mA
• Pressure gauge
• Threaded cap or blind flange depending on the nominal diameter of the manifold

Automatic pump control via fully electronic Smart Controller (SCe2.0) in a sheet metal enclosure, rating IP54, consisting of an internal control voltage supply unit, microprocessor with Soft PLC, analogue and digital inputs and outputs, for control of electronic pumps with variable frequency drives.

A working area of 1 m around the system is recommended in order to facilitate the maintenance process.

Operation/display

• Colour graphics display to output operating data, controller parameters, operating statuses of the pumps, error messages and history memory
• Menu navigation with plain text display and visualisation
• Factory-preset parameters for easy commissioning/start
• Setting of operating parameters and acknowledgement of fault messages using rotary knob
• Lockable main switch
• Operation with/without standby pump selectable
• Elapsed time indicator for each pump and for the entire system
• Switching cycle counter for each pump and for the entire system
• Fault memory for the last 13 faults

Control

• Fully automatic control for 2 – 4 frequency-controlled pumps by means of setpoint/actual value comparison
• Setpoint switchover: Second setpoint can be activated by contact
• Automatic, load-sensitive cut-in of 1 to n peak-load pump(s) depending on the control variable “pressure constant” p-c or “pressure variable” p-v
• Several user levels with different rights and menu scope
• Operating mode of the pumps freely selectable (manual, off, automatic)
• Automatic, configurable pump alternation
  • Standard setting: Impulse - The base-load pump is cycled at each new demand, regardless of operating hours
  • Alternative: Pump alternation of the base-load pump after the specified operating hours
• Automatic, configurable pump test run (pump kick)
  • Can be activated/deactivated
  • Time between two pump test runs is freely programmable
  • Disabling times can be programmed as desired
  • Speed can be adjusted as desired

Monitoring

• Actual value of the system is output via a 0 – 10 volt analogue signal for external measurement/display applications, 10 volt depending on the sensor range value
• 4 – 20 mA sensor signal (wire break monitoring of the sensor cable) for control variable actual value
• The pump mains power feed is protected via the circuit breaker
• Automatic switchover to standby pump in the event of an operating pump fault
• Monitoring of maximum and minimum system values with adjustable time delays and limits
• Zero-flow test for switching off the system when no water is being drawn off (adjustable parameters)
• Pipe filling function for filling empty pipes (initial filling of the consumer network)
• Protection against low water level integrated
• Automatic shutdown of pumps if fault occurs or operation at preset emergency operation speed

Interfaces

• Potential-free contacts for SBM/SSM collective run and collective fault signals
• Logic reversal can be applied to SBM and SSM
• Contacts for external On/Off, low water and second setpoint
• External On/Off via contact for deactivation of the system's automatic mode
