EMTYBAG – Press ENTER to manually empty the purge-air bag. Use
this function to drain the bag if it becomes contaminated with gas.
ALRMLVL – Detected gas level that causes the front panel ALARM
(red) light to turn ON and the audible alarm to sound (if AUDALRM
function is set to ALARM or ALARM/FAULT).
AUDALRM – The internal audible alarm is programmable to function as
follows:
• OFF – Audible alarm is disabled.
• ALARM – Alarm sounds when detected gas level exceeds the ALRMLVL level as evidenced by the front
panel ALARM (red) light turning ON.
• ALARM/FAULT – Alarm sounds when either the detected gas level exceeds the ALRMLVL value, or if
a system fault occurs, as evidenced by the front panel ALARM (red) light or FAULT (yellow) light
turning ON.
• LEAK DETECTOR – When selected, the monitor will produce a leak detector type of audible feedback.
At zero ppm there will be a tic every 2 seconds with the tic rate increasing up to 20 tics per second when
the ppm level reaches the ALRMLVL setting.
• TWA ALARM – Audible alarm sounds when the TWA or twa, whichever is selected by the 2ndUNIT
Function, exceeds the ALARMLVL value.
The audible alarm can be temporarily silenced by pressing the SILENCE button (page 17).
PPM LOG – Contains records of the last 200 measurements. Each
record shows the measurement’s date, time, and ppm level.
Measurements are logged at an interval determined by the LOG INT
function. After all 200 locations are filled the newest entries overwrite
the oldest entries.
Use the Keypad Up and Down buttons to change the record number by
a factor of 1. Use the Right and Left buttons to change the record
number by a factor of 10. Press ESC to return to the previous screen.
To the right, record #025 shows that a gas level of 7 ppm was measured
on 07/11/2005 at 3:35 PM.
The PPM Log can be cleared per Section 3.11.
LOG INT – Sets the interval at which measurements are logged to
memory from 1 to 9999 minutes. Factory default is 1 minute. The logged
measurements can be viewed using the PPM LOG function. Use the
Keypad to enter the desired value, and then press ENTER to save that
value and return to the previous screen.
FAULTS – Contains records of the last 30 fault events. The most recent
event is displayed when the Fault screen is first displayed. After 30
events have been recorded, the newest record overwrites the oldest. Each
record lists an event’s numeric fault code (refer to Section 3.10) plus the
date and time at which the event occurred. Use any of the Keypad
buttons to scroll through the other fault events. Press ESC to return to
the previous screen.
To the right, record #15 shows that a Purge Flow Fault (fault code
<1000>) occurred on 07/11/2005 at 12:37 PM.
DIAG – Enters the diagnostic function. Refer to Section 3.13.
