Det-Tronics PIRECL Infrared Hydrocarbon Gas Detector PointWatch Eclipse - Manual (Page 22)

20 95-8526 14.2
StaRtup
When the Eclipse is installed and wired as described in
the “Installation” section, it is ready for commissioning.
If the application requires that specific changes be
made to the factory settings, HART, MODBUS or EQP
communication will be required. Refer to the appropriate
Appendix for details.
NOTE
Ensure that controller alarm outputs are inhibited
for a minimum of 10 seconds after system power-up
to prevent unwanted output actuation.
NOTE
The safety function (gas input-to-actuation/
notification) must always be verified upon
completion of installation and/or modification.

electrical Checklist
• All 24 Vdc power conductors are properly sized and
are properly terminated.
• The 24 Vdc power supply provides sufficient load
capacity for all gas detectors.
• Using a DC voltmeter, 24 Vdc has been measured at
the detector.
• All signal output conductors are properly terminated,
and the jumper wire is installed if a non-isolated
signal output is desired.
• All relay contact output signal conductors are
properly terminated if applicable.
• All screw terminals have been tightened and all wires
pull-tested to confirm proper termination has been
accomplished.
Mechanical Checklist
• PIRECL detector is mounted to a solid surface not
prone to high vibration, shock, traumatic impact or
other undesirable condition.
• PIRECL detector is installed in proper orientation
(horizontal).
• PIRECL detector is installed to achieve weatherproof
status, e.g. conduit seals or cable glands have been
properly installed. If there is an unused conduit entry,
this entry has been sealed with a weathertight plug.
• PIRECL detector threaded covers are tightened to
engage all O-rings.
• The hex head set screw is tightened to secure the
cover and prevent access to the wiring compartment
without the use of a tool.
gas Detection and Measurement Checklist
• Vapor(s) to be detected have been identified, and
appropriate calibration gas setting for the PIRECL
has been confirmed.
• Area(s) of coverage have been identified, and
optimum detector locations for installation are
documented.
• Detector installation location is suitable for intended
purpose, e.g. no obvious impediments to contact
with the gas or vapor of interest exist or are likely to
exist.
• Proper calibration gas(es) are available to perform
proof of response test or calibration during
commissioning.
• HART communicator or similar field communicator
is available if field programming is expected or
required.
• Calibration magnet is available to initiate quick
calibration or reset.
