Det-Tronics X3301 Multispectrum IR Flame Detector SAFETY MANUAL - Manual (Page 4)

5.1 95-8582 4
Common Misuse Scenarios
Refer to the General Application Information section
of the appropriate instruction manual for detailed
information on common misuse scenarios. Application
environment considerations include the following:
• Intense IR sources should not be present in detection
area.
NOTE
The above scenarios will cause the X3301/X3302
relay or 4-20 mA outputs to annunciate a high
background fault and/or false alarm depending
on the intensity of the radiation and the relay
configuration.
• Glass and Plexiglas windows attenuate radiation and
should not be located between the detector and
detection area.
• The detector must have a direct line-of-sight to any
potential flame source in the detection area. Care
must be taken to keep physical obstructions out of
the line of view of the detector.
• The multispectrum IR flame detectors are to be
installed in locations where the risk of mechanical
damage is low.
NOTE
If the user suspects that damage or misuse has
occurred to the X3301/X3302, a full proof test
shall be performed.
NOTE
The black plastic shipping cap must be removed
prior to placing the detector into service.
START-UP AND COMMISSIONING
All safety functions of the X3301/X3302 are active
within 30 seconds of power‑up without any user action
required.
Commissioning Personnel
The Safety Certified X3301/X3302 flame detector
can be commissioned by any qualified person with
knowledge of flame detection instruments and the
configuration device being used. Refer to the Start‑Up
section provided in the instruction manual.
Relay Configuration Requirements
The end user must provide transient and current limiting
on the output contacts of the relays. The maximum
relay contact output must be limited to 2 amperes at 30
Vdc. The load must be a resistive load. The user must
protect against transients by using standard protection
methods such as proper grounding of shielded wire
and separation of relay load wires from other lines
carrying rapidly switched high current (e.g. large motor
power supply lines).
If the 0‑20 mA analog output is not being monitored for
fault conditions, the status of the Fault relay must be
monitored and appropriate action taken. The fault relay
is configured for normally energized operation.
