Midas S2
The user has generated a simulated fault.
A large concentration has been detected.
The Midas S2 requires independent
confirmation that the gas hazard is gone.
The user-specified calibration
Midas S2 can no longer regulate flow
(high or low flow condition).
The temperature is within
2 Celsius of the limits.
The sensor baseline has drifted.
The transmitter has been in
inhibit mode for too long.
LIT fail Leakage on the sample line during LIT
calibration or LIT test
The pressure sensor does not work
The user has generated a simulated fault.
The sensor baseline has drifted.
Too long since the last calibration.
The cartridge needs to be updated.

Recovery
Reset simulated fault.
Supply known clean air to the Midas S2 and clear this
fault.
Perform zero and span calibrations. Increase span calibration
period.
Check filters and pump.
Check pressure at the inlet and outlet and
assure they are within specification.
-
Check the installation environment.
Check for background gas concentration,
temperature, or humidity fluctuations.
Perform zero calibration. Replace cartridge.
Resume monitoring or increase the timeout value.
Secure sample line leakage with a blocking test and check the
connection of the sampling line. If there is no leakage, service or
replace the main module.
Service or replace the main module.
