Det-Tronics ATX10 Transmitter SAFETY MANUAL - Manual (Page 4)

1.2 95-8658 4
NOTE
Prior to device configuration all alarm outputs
must be bypassed. The device is not safety
certified during configuration change activities.
NOTE
All configuration changes to the FlexSonic
Acoustic Detector (including any changes via
SD card operations) must be verified by the user
via a proof test, power cycle and re-check of
settings, or other appropriate method. The safety
functionality must be validated prior to reliance
on the product for safety protection.
Configuration Protection
Upon completion of installation and commissioning, it
is required that the user password-protect the safety
related parameters that are accessible via HART or
RS485 in order to prevent accidental or deliberate
change of configuration data during normal operation.
To password protect the FlexSonic Acoustic Detector,
the user must set the write-protect function to “on” and
enter an 8 character password. The user should check
the write protect status to ensure that it is set to “on”.
The user will be required to disable write protect prior to
any future configuration changes, and must re-enable
write protect upon completion of these changes to
ensure that HART and RS485 communication remain
non-interfering.
oPERATIoN, MAINTENANCE, INSPECTIoN AND
PRooF TESTING
All normal installation and startup recommendations
as documented in the FlexSonic Acoustic Detector
instruction manual are applicable to the Safety Certified
FlexSonic Acoustic Detector.
Safety-Certified FlexSonic Acoustic Detectors require
proof testing to be performed in all cases.
Personnel performing proof test procedures shall be
competent to perform the task. All proof test results
must be recorded and analyzed. Any corrective actions
taken must be documented in the event that an error is
found in the safety functionality. The proof tests must
be performed prior to commissioning the device and at
least as often as specified in Table 1.
WARNING
Failure to perform the specified testing and
inspection may lower or void the SIL rating for the
product or system.
VISUAL FIELD INSPECTIoN PRooF TEST
Tools Required: None
Visual inspection of all Safety-Certified FlexSonic
Acoustic Detectors shall be conducted as needed
to confirm that no external blockage of the sensor
cover exists, eg. debris, trash, snow, mud, external
equipment, etc. Corrective action shall include
removal of such impediments should they exist. All
acoustic detectors must be inspected to ensure that
they are capable of providing expected performance
and protection.
Completion of Visual Field Inspection Proof Test must
be recorded and documented in the SIS logbook.
RESPoNSE PRooF TEST
Tools
Required: Magnetic tool available from
Det-Tronics, or
HART handheld communicator
The Manual AIC test provides a self check of the
acoustic detector safety function. All acoustic detectors
must be performance tested using the Manual AIC
test procedure and inspected to ensure that they
are capable of providing expected performance and
protection. The Manual AIC test can be initiated and
reset by placing the magnetic tool on the icons on
the ATX10 display, via HART command, or via RS485
command.
Proof Test Name Commissioning Frequency
Visual Field Inspection Proof Test Yes
As needed, depending on level and type of
contaminants present
Response Proof Test Yes 1 year
