FM100 Fume hood monitoring system according to EN 14175

Transcription

1 Functional description Performance features Functional description For use as a monitoring and alarm system for exhaust fl ows in various applications, such as fume hoods, safety cabinets and other extraction units. A microprocessor controlled security system for monitoring the containment-safe operating status of fume hoods. An acoustic and optical alarm is activated as soon as the exhaust fl ow falls below or exceeds the programmed threshold values. FM00 fulfi lls the standard EN 475. That means security for the laboratory worker. FM00 is suitable for all fume hood constructions, making it easy to carry out new installations and re-fi ttings on existing fume hoods. In addition to clientspecifi c designs a wide range of different function displays are available (see the data sheet Standard function displays). A suitable measurement system is vital for precise and safe monitoring. For safe operation with the static differential pressure transmitter and reproducible and exact measurement results we recommend the SCHNEIDER venturi measuring tube or measuring tube. Function and control panel The function and control panel is available with its own case or as a built-in version in different variations. Clientspecifi c designs are implemented quickly and costeffectively. Functions: Acoustic and optical alarm (red LED) for insuffi cient exhaust/supply air Optical display (green LED) for suffi cient exhaust/ supply air RESET button to acknowledge the acoustic alarm Plug for programming via the service module SVM00 or laptop Performance features microprocessor controlled monitoring system low cost system integrated power supply 20V AC all system data are saved mains voltage failure-safe in the EEPROM programming of all system values via service module SVM00 or laptop computer software PC2000 Monitoring of supply and exhaust air systems Static differential pressure transmitter with long-term stability. Measuring range: pascal or pascal. Optionally with air fl ow sensor (face velocity) Monitoring of fume hood operation to EN 475 with acoustic and optical alarms Optional monitoring of exceedance of a programmable volume fl ow with optical alarm Optical and optional acoustic alarm for the operating status Sash > 50cm Programming of a second monitoring value (reduced volume fl ow during night-time operation) Emergency power pack (optional) for mains voltage failure-safe operation Suitable for all fume hood constructions Options: Button light ON/OFF (fume hood interior) Optical display (yellow LED) when the maximum exhaust air is exceeded Yellow blinking LED as an optical alarm for the operating status Sash > 50cm Battery backup p Fume hood monitor FM00 20 VAC Power Day/Night operation Digital In-/Outputs 4 Fume hood Functional display High Okay Analogue Output 5 Air volume display m h 6 Low Schematic diagram: Fume hood monitoring system FM00 Supply air Reset RS 22 Monitoring according to EN 475 Servicemodule SVM-00 Venturi measuring tube F F2 F 2 Static differential pressure transmitter or alternate Air flow sensor Laptop 4 Digital In-/Outputs for special application Analogue Output (0...0 VDC) for room group controller * 0, 6 Optional air volume (m /h) or air flow (m/s) display Technical documentation FM00 Date: 0/2008
