Air volume flow monitor

Fume hood air volume flow monitor device with integrated microprocessor, two independent watchdog circuits and static differential pressure transmitter. Monitoring of the safe fume hood operation according to EN 14175 with audible and visual alarm. Visual and optional audible alarm for the operation mode “sash opening > 50 cm”. Integrated charging circuit for the battery backup. Optional monitoring of the exceeding of a parameterised volume flow with visual alarm and parameterisation of a second monitoring value (reduced volume flow during night operation). System data storage via voltage fail-safe EEPROM. Applicable for all types of fume hoods.

Technicalfeatures:

  • Voltage fail-safe storage of all system data on the EEPROM
  • Free parameterisation of the system data via service module SVM-100 or optional via PC, e. g. set value of air volume flow as well as request of all actual values
  • Monitoring of the ventilation system provided by the customer
  • Sensor monitoring regarding plausibility
  • Static differential pressure transmitter according to differential pressure method for the continuous measurement of the actual value in the range 4 to 240 pa or optional 6-640pa
  • Visual and audible alarm indication of operating modes and troubles
  • Night setback (monitoring of reduced operation)
  • Automatic switchoverto battery backup during power failure
  • Integrated battery backup charging circuit
  • Second display and control panel can be connected (applicable for pass through fume hoods)
  • Applicable for all kind of laboratory exhaust devices according to EN 14175

Optional

  • Numeric LED-display of the exhaust volume air flow (m³/h)

  • LON-network for decentralised networking, FTT-10A

  • Electronic zero point calibration for the sensor

Control and display panel

Control and display panel integrated in the fume hood with acoustical alarming and the following functions:
  • Prepared for the connection to an optional numeric display to indicate the exhaust air flow in m³/h or the air inflow in m/s
  • Serial standard interface (RS232) to connect a service terminal or PC for configuration and commissioning

Controlbuttons

  • Alarm acknowledgement
  • ON/OFF
  • Reduced operation (VMIN respectively night setback)
  • Light ON/OFF

LED-display

  • Green light for operation (exhaust air flow in the permitted range) with a illuminated area of 1 cm²
  • Red light for critical undercut of the minimum exhaust air flow (error) with an illuminated area of 1 cm²
  • Yellow light for exceeding of the maximum exhaust air flow VMAX and override operation
  • Yellow light for reduced operation VMIN
  • Green light for ON/OFF
  • Yellow light for closing sash with an illuminated area of 1 cm²

Analogue output

  • 1 standardised analogue outlet 0(2)…10 V DC for actual value of exhaust air, applicable for direct control of room group controller or of the building management systems(BMS)

Relay output

All relay contacts are potential free with a switching power of 250 V AC/3 A
  • Alarm output (fault indication), 1 x switchover contact

  • Light on/off, 1 x make contact (230V AC/12 A)

  • ON/OFF (feedback to DDC), 1 x switchover contact

  • DAY/NIGHT (feedback to DDC), 1 x switchover contact

Analogueinput

  • 1 standardized analogue input 0(2)…10 V DC/1 mA for special applications

Digital inputs

  • Motor on detection, galvanically isolated, 230 V AC/20 mA. For activation of the volume flow display during operation of the exhaust fan

  • ON/OFF

  • Day/night-changeover (monitoring during reduced operation)
  • External alarm

  • Sash opening > 50 cm

Interface (optional)
