Frequently Asked Questions

• What kind of applications can a quattro be used for?

  The Quattro is extremely suitable for solar energy applications. It can be used for building autonomous systems as well as grid- connected systems. Emergency power or autonomous operation on mains failure

• What are the operating instructions for the gasalert Quattro?

  For complete operating instructions, refer to the GasAlertQuattro Technical Reference Guideprovided on the CD-ROM. The GasAlertQuattro gas detector (“the detector”) is designed to warn of hazardous gas levels above user-defined alarm setpoints. The detector is a personal safety device. It is your responsibility to respond properly to the alarm.

• How many AC inputs does a Quattro have?

  Two AC inputs with integrated transfer switch The Quattro can be connected to two independent AC sources, for example shore-side (grid-) power and a generator, or two generators. The Quattro will automatically connect to the active source. Figure 1: Block diagram

• How is the water supplied to a quattro?

  Quattro consists of an electric motor which drives a pulveriser, with a separate water pump that flushes the hopper and outlet pipe-work. Water is supplied via mains supply or a storage tank through an inlet solenoid valve.

• What does the gasalert Quattro gas detector do?

  The GasAlertQuattro gas detector (“the detector”) is designed to warn of hazardous gas levels above user-defined alarm setpoints. The detector is a personal safety device. It is your responsibility to respond properly to the alarm. Note The detector is shipped with English as the default displayed language.

• How often does a gasalert Quattro need to be calibrated?

  BW recommends that the sensors must be calibrated regularly and at least once every 180 days (6 months). • Calibrate only in a safe area that is free of hazardous gas in an atmosphere of 20.9% oxygen. • The combustible sensor is factory calibrated to 50% LEL methane.

• What is the operator's manual for a gas detector?

  The operator’s manual provides basic information to operate the GasAlertQuattro gas detector. For complete operating instructions, refer to the GasAlertQuattro Technical Reference Guideprovided on the CD-ROM. The GasAlertQuattro gas detector (“the detector”) is designed to warn of hazardous gas levels above user-defined alarm setpoints.

• What happens to the LEL sensor when exposed to gas?

  This effect, known as inhibition, is usually temporary but in extreme circumstances can impair the sensitivity of the LEL sensor. After any gas exposure that causes an alarm in the toxic gas sensors, the LEL sensor should be verified with a bump test, and recalibrated if necessary.
