Det-Tronics PIRECL Infrared Carbon Dioxide Gas Detector PointWatch Eclipse - Manual (Page 30)

B-2 95-8676 2.1
aTex Special conditions for safe use (general):
• The Infrared Gas Detector model PIRECL shall be installed in places where there is a low risk of mechanical damage.
• The field wiring terminal connections are certified for a single wire in size from 0.2 to 2.5 mm
2 , (or two conductors with
same cross section 0.2 to 0.75 mm 2 ).The screws must be tightened down with a torque 0.4 to 0.5 Nm.
• The metal housing of the model PIRECL Infrared Carbon Dioxide Gas Detector must be electrically connected to earth
ground.
• The Infrared Gas Detector model PIRECL has an ambient temperature rating of –55°C to +75 °C.
• Alarm output latching requirement: High alarm outputs must be configured as latching, either as part of the alarm
operation of the gas detector itself (in stand-alone applications), or as a function of the “high alarm” indication within the
controller that is directly connected to the gas detector (for remote applications).
Special conditions for safe use for the [ib] harT communication port only:
• The PointWatch Carbon Dioxide Infrared Gas Detector model PIRECL shall be powered from a Safety Isolating Transformer
according to EN60742 or EN61588.
• The maximum cable distance between the HART Communicator and the PIRECL Infrared Carbon Dioxide Gas Detector
is 610 meters.
additional Safety notes:
• The following warning is on the product: Warning: Do not open when an explosive gas atmosphere may be present. For
ambient temperature above 60°C use field wiring suitable for maximum ambient temperature. For temperature below
–10°C use suitable field wiring for the lowest temperature.
• The ambient temperature range is limited to –55°C to +75°C (for Ex d version) or –50°C to +75°C (for Ex de version).
• Cable, bushings and the conduit entries shall be of a type already certified according to relevant ATEX standard, so the
protection principle employed will not be impaired.
• Unused conduit entries shall be closed using stop plugs certified for the conditions of use (IP66/IP67 minimum). The stop
plugs should be removable only with the aid of a tool.
• The terminal compartment for Eclipse without relays is designed for either an increased safety “e” termination or a
flameproof “d” termination of the supply cable. If a flameproof connection is chosen, then an ATEX certified cable entry
device certified to EN60079 must be used. The Eclipse with relays requires Ex d cable entry devices only.
• Shielded cable is required.
• The measuring function of the Infrared Gas Detector model PIRECL CO2 version, for explosion protection, according to
Annex II clause 1.5.5, 1.5.6 and 1.5.7 of the Directive 94/9/EC is NOT covered in this EC-Type Examination Certificate.
