PASSWORD PROTECTION
The ATX10 allows the use of a password for restricting
changes to configuration parameters and limiting
access to safety critical commands.
The ATX10 is shipped from the factory with the password
protection (Write Protect) feature enabled. Refer to the
AC100/ATX10 HART Addendum (number 95-8698) for
complete information regarding use of the Write Protect
feature.

NUISANCE SOURCES
Most industrial or processing environments are
relatively free from the higher frequency sound energy
that is characteristic of a gas leak, however, there are
instances where high frequency nuisance sources
exist. The sources may include, but are not limited to:
• Rotating machinery / gear meshes
• Bearings/fans motors
• Metal-to-metal contact / chains
• High velocity wind through rigging
The FlexSonic Acoustic Detector can be effectively
employed to record the acoustic background
environment unique to an installation and provide a
clear display of the information using the Acoustic
Inspector software package. The ability to view the
actual acoustic environment enables users of the
FlexSonic Acoustic Detector to make intelligent, data-
based decisions on how to best address nuisance
sources in the alarm profile.
FRIENDLY LEAkS
The FlexSonic Acoustic Detector recognizes the
acoustic signature of pressurized gas escaping.
Therefore, so called ‘friendly’ sources of compressed
gas leaks such as air lines and relief stacks may be
detected as well.
While some non-hazardous pressurized gas escapes
may be effectively ignored through the patented learn
function, the expected hazardous leak SPL must
be greater than the non-hazardous leak SPL for the
detector to effectively discriminate between the two
sources.
If the time duration of the non-hazardous source is
relatively short, the user settable alarm delay setting
can be adjusted to reject short duration leaks. Refer
to the “Operation” section of this manual for details on
alarm adjustments.
