Calibration
Tools Required: Compressed Calibration Gas Kit
provided by Det-Tronics
Magnet or HART Communicator
Calibration shall be conducted when required as
documented in the Calibration section of the GT3000
instruction manual. It is permissible to conduct
the calibration using either the onboard magnetic
calibration switch or using an approved HART handheld
field communicator. In all cases the GT3000 and
attached transmitter should be allowed to warm up for
one hour minimum before conducting calibration.
Completion of the Response Proof Test must be
recorded and documented in the SIS logbook.
WARNING
Any external alarm equipment, systems or
signaling devices that were disabled must be
re-activated at the conclusion of proof testing
activities.
FAULT/FAILURE ACTIoN PLAN
In the event that a Calibration does not result in an
acceptable Response Proof test, then the standard
Maintenance and Device Repair and Return
procedures as listed in the GT3000 instruction manual
must be followed. Any failure to successfully complete
the Response Proof Test must be recorded and
documented in the SIS logbook.
PRoDUCT REPAIR
Field repair of the GT3000 is limited to replacement of
the filter and/or sensor module. All other device repairs
must be conducted at the factory. No firmware changes
are permitted or authorized. All failures detected
by the device diagnostics or by the Proof Tests that
cannot be resolved through the procedures described
in the FAULT/FAILURE ACTION PLAN section must be
reported to the manufacturer.
oPERATING, ENVIRoNMENTAL, AND
PERFoRMANCE SPECIFICATIoNS
The Safety-Certified GT3000 product versions fully
comply with, and must be operated in accordance
with the functional, environmental, and performance
specifications provided in the GT3000 instruction
manual. A 24 hour mean time to repair should be
assumed for safety availability calculations. All GT3000
diagnostics have a maximum one hour test interval.
SPARE PARTS
Refer to “Ordering Information” in the GT3000
instruction manual. Safety Certification is based on a
sufficient number of spares to achieve a 24 hour mean
time to repair.
