RAEGuard Lite User Manual 6.1 Display RAEGuard Lite display features a graphical dot matrix Liquid Crystal Display with Numeric and bar-graph current concentration level, Unit, Alarm/Fault/Warning indication, Chinese/English language display, a target for magnetic switch activation etc. When an "event" occurs or the instrument is operated, the backlight of the LCD is triggered.
Nore: Fault, inhibit and warning current are set to 1 mA or 2 mA or 3 mA. For more information on fault codes and warning codes, please refer to Section 6.3 Magnetic Wand Users can operate RAEGuard Lite via Magnetic Switch. There are 3-switch ▲, √, ▼ on the transmitter.
RAEGuard Lite User Manual 6.4 Operating mode RAEGuard Lite detector offers three operating modes. Normal monitor mode is the normal operating status while RAEGuard Lite measures, and displays gas concentration. While the instrument alarm, fault, warning, etc. occur, the LED light will indicate the corresponding status of the instrument, and the corresponding information will be displayed on the LCD.
RAEGuard Lite User Manual 7 First Time Switch on (Commissioning) Warning The following procedure requires the Transmitter Cover to be removed while carrying out supply voltage checks. Therefore, the appropriate permits to work should be sought in preparation. Prior to carrying out any HOT WORK ensure local and site procedures are followed.
