Introduction

This manual will assist you in the installation of the FAILSAFE Module (SKU SS-PCB-GEN2) into existing handheld or panel mount Nuvair Pro Alarm analyzer powered externally. This manual will also help customers understand the function of Nuvair Pro Alarm analyzers equipped with a factory-installed FAILSAFE Module.
The Nuvair Pro Alarm analyzer series are gas analyzers with alarms (visual and/or audible) that activate when user-defined set points (low and/or high) are violated.
Be sure to read the entire manual.

Symbol Conventions

This manual uses certain words and symbols to call your attention to conditions, practices or techniques that may directly affect your safety. Pay particular attention to information introduced by the following symbols or words:

SYMBOL MEANING DESCRIPTION
   DANGER Indicates an imminently hazardous situation, which if not avoided,

will result in serious personal injury or death.
  CAUTION| Indicates a potentially hazardous situation, which if not avoided, could result in serious personal injury or death.

WARNING

| Indicates a potentially hazardous situation, which if not avoided, may result in minor or moderate injury. It may also be used to alert against unsafe practices.
   NOTICE| Notifies people of installation, operation or maintenance information which is important but not hazard-related.

Module Description

As originally designed, most Nuvair Pro Alarm analyzers are:

  • Manually controlled by an On/Off button on the front of the analyzer control panel.
  • Equipped with a relay that can activate or disable external devices.

Some customers with a compressor-integrated analyzer want the compressor to shut down automatically if analyzer power is interrupted or the analyzer goes into alarm. In response to customer requests, Nuvair developed the FAILSAFE Module. Adding the FAILSAFE printed circuit board (PCB) to your existing Pro Alarm analyzer will automatically disable compressor power if:

  • Analyzer power is interrupted, or
  • Analyzer goes into alarm.

The FAILSAFE Module can be installed on the following on Nuvair Pro Alarm analyzers originally equipped with these power configurations:

  • Wall plug-in
  • DIN power

The FAILSAFE Module is not compatible with any battery-powered Pro Alarm analyzer.
By installing the FAILSAFE Module, the analyzer will automatically power on when compressor power is turned on.
The FAILSAFE Module can be purchased separately by existing Pro Alarm analyzer owners, or the analyzer can be returned by the customer to the Nuvair production facility in California (USA) for installation.

WARNING
This manual describes how a customer can install the FAILSAFE Module to existing Pro Alarm handheld or panel mount analyzers. To complete this installation, the customer must have a rudimentary knowledge of, access to, and the ability to use and understand:

  • Electronic components
  • Small Phillips screwdriver
  • Solder, and
  • Soldering iron.

DANGER
Failure to properly install the FAILSAFE Module will result in the Pro Alarm analyzer not functioning properly. An improperly operating analyzer will not alarm and will not alert users that dangerous gas conditions exist. Exposure to dangerous gases will result in significant injury or death.
