ALARM
(red) light turns ON if the detected gas level exceeds a programmed alarm point.
An audible alarm also sounds if the AUDALRM function is activated. Pressing the front panel
SILENCE
button turns OFF the audible alarm, but the ALARM light will continue to flash for as long
as the detected gas level is above the alarm point. The audible alarm will reactivate if the gas-alarm
condition is not cleared within the time period set by the SILENCE function (refer to text starting on
page 14).
FAULT (yellow) light turns ON if a fault occurs (see Fault Code list on page 18). An audible alarm also
sounds if the AUDALRM function is activated. Pressing the front panel SILENCE button turns OFF the
audible alarm, but the FAULT light continues to flash for as long as the fault is present. The audible
alarm will reactivate if the fault condition is not cleared within the time period set by the SILENCE
function (refer to page 14). Both the FAULT light and audible alarm will automatically turn OFF after
the cause of the fault has been eliminated. A log of the last 30 fault events can be viewed using the
monitor’s FAULTS function (page 16).
3.6 Battery Charging and Using
3.6.1 Charging the Battery
The monitor is powered by a rechargeable battery pack located in a pouch on the side of the monitor’s soft
carrying case. The battery pack can be recharged at any time, regardless of the battery’s current charge state.
The AC adapter provided accepts voltage inputs of 100 to 240 VAC. Plug the adapter into the wall, then into the
battery. Disconnect the adapter when the battery is fully charged. A fully charged battery pack will power the
monitor for approximately 8-12 hours.
3.6.2 Using the Battery
The PAGM is designed for a 16VDC input. Following the instructions for the particular battery in use, set the
output voltage to 16V. Plug the battery into the instrument's battery input port and the instrument is ready for
use.
3.7 Display Screens
3.7.1 Initial Power ON
When the monitor is first powered ON, all front panel lights turn ON and a splash screen appears showing the
monitor’s current firmware revision level. After a brief moment the Warm
Up screen is displayed along with the
front panel ON
light (green) blinking.
The monitor requires 5 minutes to warm up from a cold start; after which, the ON light glows steady and the
Data
Display screen appears.
3.7.2 Data Display Screen
During normal operation the Data
Display screen shows when the monitor is performing the following functions:
MEASURE
indicates that the monitor is actively measuring the refrigerant gas level at the
sample point. To reset the peak value to zero, press the ENTER
button.
PURGE
is displayed when the monitor is resetting its infrared detector to a baseline ppm value
using fresh air that is being drawn in through the Purge Air Inlet Port. This purging process is
performed on an “as needed” basis, which is normally once every 6 to 8 minutes.
