Situation Explanation/Solution
IDS display reads “Unavailable
Gas” (or “No Fresh Air” when
connected to v5.0 DSS or later)
Gas that was required for a bump test or calibration
was not available.
The gas cylinder may be low or empty.
Ensure that the Gas In configuration in DSSAC is
correct.
If using a cluster, ensure that the IDS to which the gas
is connected is running.
If more than one gas is missing, the IDS displays the
first gas it needed, but did not have access to. Thus, if
the first missing gas is then provided, but a second gas
is still missing, the user is presented with a second
“Unavailable Gas” message, but with the chemical
symbol of the second gas.
If prior to an aborted cal/bump the pressure of the
cylinder was previously “OK” or “Low”, then
underneath the Unavailable Gas message, the word
“Low” or “Empty” appears (respectively)
If the server determines that a scheduled or forced
calibration or bump cannot occur because a needed gas
cylinder is empty or expired, then the IDS displays
“Empty” or “Expired” (as appropriate) along with the
chemical symbol of the missing gas.
