The default condition is for all detectors to be active.
Detector LEDs
: indicate location of radiation alarm (see front panel
drawing in front of manual for LED layout).
Status LEDs (side of portal):
(see front panel drawing in front of manual
for LED layout).
Enter/Checking green LED:
normally illuminated prior to any personnel
entry, indicating that the system is ready to take a count. It flashes to
indicate the system is checking for excess radiation. It stops flashing at
the end of the count time in stop-and-count mode or whenever the user
leaves the portal in walk-through mode.
Incomplete/Updating yellow LED:
indicates that a count was in progress
and the subject stepped out of the portal before the count was complete.
The INCOMPLETE LED stays on for the incomplete time or until the
subject steps back into the portal. An INCOMPLETE resets the count
time.
If no one steps back into the portal during the incomplete time, the portal
monitor goes back to the ready state, illuminating the ENTER LED.
This LED also indicates UPDATING background while flashing. Do
not enter or allow personnel within 1.8 m (6 ft) while the unit is updating
background.
Radiation Alarm red LED:
indicates that the system has detected
radiation levels above background.
Instrument Failure red LED:
indicates that the system has detected a
high- or low-background condition. If there is a background problem, the
UPDATING LED will also be illuminated.
