X3301 MAgNETIC Oi PROOf TEST
Tools Required:
• Magnetic oi test tool (part number 102740-002)
All flame detectors must be performance tested using
the Magnetic oi Procedure and inspected to ensure that
they are capable of providing expected performance
and protection. Note that the Magnetic oi Procedure
and Manual oi Tests are not interference free. During
these tests the unit is not performing normal flame
detection functions. Model X3301 provides an onboard
status LED, which indicates Green color when internal
operational parameters are normal. Upon successful
completion of the Magnetic oi test, the LED changes
to a Red color and an alarm status is sent to the EQP
controller. In the event the proof test is unsuccessful, the
LED remains Green and the controller does not indicate
a fire alarm.
PIRECL VISUAL fIELD INSPECTION PROOf TEST
Tools Required: None
Visual inspection of all Safety-Certified PIRECL Gas
Detectors shall be conducted weekly to confirm that no
external blockage of gas/vapor path into the sensing
chamber exists, e.g. 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. Model
PIRECL provides an onboard status LED that indicates
Green color upon inspection when internal operational
parameters are normal. Abnormal operating parameters
are indicated by Yellow color (Fault) or Red color (Alarm).
PIRECL gAS RESPONSE PROOf TEST
Tools Required:
•
Calibration Gas Kit (part number 006468-001)
available from Det-Tronics
This proof test, commonly referred to as a “gas bump
test”, requires application of high accuracy compressed
calibration gas to the detector while in NORMAL
operational mode and inspecting the signal output level
to ensure that the signal output is accurately indicative of
the applied test gas concentration.
When test gas is flowing into the detector, inspection
of proper gas response can be made by reading the
output displayed on the controller. Criteria for inspection
pass is a response signal within ±3% of applied gas
concentration (50% LEL test concentration applied).
If response test is not within acceptable limits, then a
Full Calibration procedure must be performed and Gas
Response Proof Test re-performed.
EQP USER LOgIC VERIfICATION
All user Safety Logic needs to be fully tested and
verified using the safety inputs and outputs. This is a
commissioning activity, however, if logic is modified
in the future, proof testing must be repeated. If the
Controller is replaced, project information must be
loaded into the new Controller and verified. The CRC
of project related data is calculated and saved by the
controller after each project download. The project CRC
can be viewed on the Controller’s display under User
Logic/General Info/Logic CRC. The project CRC should
be recorded and saved when proof testing is completed.
The project CRC from the Controller must be compared
to the saved value when a Controller is replaced to avoid
complete proof testing of the system.
INSTALLATION
General installation instructions are found in the
instruction manual for the EQP system, form number
95-8533.
Like other Det-Tronics EQP products, the ingress
protection rating of the EQP Safety Controller, EDIO,
and AIM is IP20. It will be necessary to mount the
EQP Safety Controller, EDIO, and AIM in a suitable
enclosure to provide mechanical and ingress protection
appropriate to the particular application. X3301 is IP66
minimum and PIRECL is IP67 minimum.
Access can be restricted by mounting the EQP
controller in a locked enclosure.
COMMISSIONINg PERSONNEL
The Safety Certified EQP System can be commissioned
by any qualified person with knowledge of EQP System
instruments and the configuration device being used.
SUITABLE APPLICATIONS
The EQP Safety System can be used to provide safety
functions up to Safety Integrity Level 2 (SIL 2). It can be
used in low demand applications only.
Typical low demand applications are:
• Fire and Gas protection systems, which monitor for the
presence of fire or a release of gas, and annunciate/
release when demanded upon.
In this case, the process safety time must be greater
than the response time of the EQP Safety System.
