and the system will try again. If it can not complete a good scan, a malfunction
will be generated. Some malfunctions, such as a failure of the optional Line Leak
Check, do not interrupt the operation of the ACM 150 monitor. It will continue to scan
normally after this malfunction is detected. Other malfunctions, such as a "bench
time-out" will cause scanning to be interrupted.
Screening data
Warn / Alarm 1/Alarm 2, questionable results and shakedown
During the first few weeks of operation, expect some "shakedown" of the ACM 150
monitor to be necessary. You may get some low level readings for certain chemicals,
especially if they are measured in the water vapor region of the infrared spectrum.
It may be necessary for the Honeywell Analytics application chemist to adjust the
analytical method for the specific background purge gas and normal air chemistry at
the user's location.
During this initial operating period, collect infrared spectra and send it to Honeywell
Analytics. The application chemist will use this information to make adjustments to
the analytical methods. If necessary, new methods will be generated and sent to
the user or installed by HA or its agent. The user should also collect and the spectra
generated during any of the following events:
Demand Scans
Warn / Alarm 1/Alarm 2 Incidents
Gas Tests
Malfunction messages generated during this initial period may occur due to the
characteristics of the particular installation. Notify Honeywell Analytics Service
Department or its agent of all malfunctions, even if they are corrected by the user
or are self-corrected, during the first few months of operation. Thereafter, the user
can limit such notification to times when service assistance is needed to resolve a
problem.
Used when a chemical level is
suspected or unknown odor ('chemical
stranger') is present
Includes both known and suspected
events as well as questionable events,
where a false alarm may be suspected
Where a known chemical was
introduced by the user and the ACM
150 monitor fails to report it or does not
agree with the concentration level
