Det-Tronics OPECL Infrared Hydrocarbon Gas Detector - Manual (Page 3)

Important
Be sure to read and understand the entire
instruction manual before installing or operating
the gas detection system. This product is intended
to provide early warning of the presence of a
flammable or explosive gas mixture. Proper device
installation, operation, and maintenance is required
to ensure safe and effective operation.
application
The Open Path Eclipse Model OPECL is an open
path infrared gas detection system that provides
continuous monitoring of combustible hydrocarbon gas
concentrations in the range of 0 to 5 LFL-meters, over a
distance of 5 to 120 meters. Standard system outputs
include an electrically isolated/non-isolated 4-20 mA dc
current output, with HART communication and RS-485
MODBUS communication. Alarm and fault relays are
available as an option. A LON based model (with no
analog or relay outputs) is available for use with Eagle
Quantum Premier systems.
The system consists of two stainless steel modules
— a transmitter and a receiver, along with mounting
fixture hardware. Both modules are powered from an
external 24 volt DC supply. The receiver provides the
measurement signal outputs, and is furnished with
an onboard "status indication" LED and an internal
magnetic calibration switch. The transmitter houses
dual xenon flashlamps. Both modules are installed at
approximately the same elevation and must be aligned
to point directly at one another. No direct electrical
interconnection between the two modules is required.
The Open Path Eclipse is ideal for use in harsh outdoor
environments and is certified explosion-proof for use in
Class I, Division 1 and Division 2 hazardous areas. It
can be used as a stand-alone detector, or as part of a
larger facility protection system using other Det-Tronics
equipment such as the Eagle Quantum Premier Fire and
Gas Detection/Releasing System.
