SAFETY CERTIFIED MODEL OPECL

OPEN PATH ECLIPSE IR GAS DETECTOR

This manual addresses the speciﬁc requirements and

recommendations applicable to the proper installation,

operation, and maintenance of all Safety-Certiﬁed

(SIL-Certiﬁed) Model OPECL Open Path Eclipse IR Gas

Detector product versions. For complete information

regarding system overview, performance, installation

(including alignment), operation, maintenance and

speciﬁcations of the Model OPECL, refer to instruction

manual 95-8556.

QUALITY POLICY STATEMENT

All quality assurance control measures necessary for

safety management as speciﬁed in IEC 61508 Part 1

have been implemented. The quality management

system of Det-Tronics is based on the requirements

of EN ISO 9001 and ANSI/ASQC Q9001 through the

application of the United Technologies Company

Achieving Competitive Excellence (ACE) program. In

addition, the Quality Management System complies

with the European ATEX Directive requirements per EN

13980, the International Electrotechnical Commission

requirements per OD005/V2, and the supervised

testing requirements per ISO 17025.

SAFETY MESSAGES

Procedures and instructions in this section may

require special precautions to ensure the safety of

personnel performing the operations. Information that

raises potential safety issues is indicated by the word

“Warning”. Always read and understand these safety

messages.

WARNING

The Model OPECL Gas Detector is intended for

use in hazardous environments that may include

explosive levels of ammable gases and vapors.

This product must be properly installed, operated

and maintained. Improper installation or use

could result in an explosion or re resulting in

death or serious injury.

SAFETY MANUAL Infrared Hydrocarbon Gas Detector Open Path Eclipse SIL 2 Certified Model OPECL SAFETY CERTIFIED MODEL OPECL OPEN PATH ECLIPSE IR GAS DETECTOR This manual addresses the specific requirements and recommendations applicable to the proper installation, operation, and maintenance of all Safety-Certified (SIL‑Certified) Model OPECL Open Path Eclipse IR Gas Detector product versions.
PAGE 2
DESIGN DIAGNOSTIC RESPONSE TIME The Model OPECL Open Path Eclipse Gas Detector is an infrared hydrocarbon gas detector that is classified as Type B smart device according to IEC61508. It provides an isolated 4-wire 4-20 mA output that is proportional to hydrocarbon vapor concentrations from 0-5 LFL-meters.
PAGE 3
Common Misuse Scenarios Relay Configuration Requirements • Do not install the OPECL on unstable or vibration prone structures; a 3 meter maximum height is recommend when using a vertical post. Only the OPECL gas detector’s High Alarm and Fault relay outputs may be used as part of a Safety Certified system. 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 5 amperes at 30 Vdc.
PAGE 4
When the test film is in the light beam path of the detector, inspection of proper analog signal level output can be made by reading the analog signal output displayed on the control device. Criteria for inspection pass is a response signal within the range 0.75-1.5 LFLmeters for p/n 007902-002 or 1.9-2.5 LFL-meters for p/n 007902-003. If response is not within acceptable limits, refer to the Fault/Failure Action Plan.
PAGE 5
OUTPUT RESPONSE PROOF TEST FAULT/FAILURE ACTION PLAN In the event that a Calibration does not result in acceptable Gas Response Proof test, then the standard Maintenance, Troubleshooting, and Device Repair and Return procedures as listed in the OPECL instruction manual must be followed. Any failure to successfully complete the Gas Response Proof Test must be recorded and documented in the SIS logbook and reported to the manufacturer.

CERTIFICATION AND FAILURE RATE DATA Additional CERTIFICATIONS All Safety-Certified OPECL models are certified compliant to: FM, CSA, ATEX, IECEx, CE. Refer to the Model OPECL Instruction Manual for details. IEC61508: 2010 Type B Device Systematic Capability: SIL 2 certified HFT: 0 TERMS AND DEFINITIONS Low Demand Mode PFDavg should be calculated for any safety instrumented function using the OPECL. (Refer to FMEDA report for necessary information, including DU rate.) 4-20mA SFF = 93.2% Relay SFF = 92.
