Det-Tronics PIRECL Infrared Hydrocarbon Gas Detector PointWatch Eclipse SAFETY MANUAL - Manual (Page 4)

5.1 95-8630 4
Configuration
A HART handheld communication device can be
used to monitor internal status or to modify the factory
settings of the PIRECL. Refer to the PIRECL HART
Communication Appendix in the PIRECL instruction
manual for guidance on using HART communication.
Alternate protection measures must be used as needed
while modifications to safety related parameters are
being made.
While in the process of calibrating the detector, it is not
able to signal an alarm. During this time, the device is
not performing its safety function.
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 PIRECL 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 in
order to prevent accidental or deliberate change
of configuration data during normal operation. To
password protect the PIRECL, 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 communication remains
non-interfering.
oPErATioN, MAiNTENANCE, iNSPECTioN AND
ProoF TESTiNG
All normal installation and startup recommendations
as documented in the STARTUP section of the PIRECL
instruction manual are applicable to the Safety Certified
PIRECL.
Safety-Certified PIRECL models 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 PIRECL models
shall be conducted as needed to confirm that no
external blockage of gas/vapor path into the sensing
chamber exists, eg. debris, trash, snow, mud, external
equipment, etc. Corrective action shall include
removal of such impediments should they exist. All
gas detectors must be inspected to ensure that they
are capable of providing expected performance and
protection. PIRECL provides an onboard status LED
that indicates Green color upon inspection when
internal operational parameters are normal. Abnormal
operating parameters are indicated by Amber color
(Fault) or Red color (Gas Alarm).
Completion of Visual Field Inspection Proof test must
be recorded and documented in the SIS logbook.
