  • Page 8: The Er060Autol System

    1.2 The ER060AUTOL system ER060AUTOL is designed to be used for flue gas monitoring in stacks/ducts in combina- tion with one Opsis LD500 analyzer. The ER060AUTOL consists of one emitter, EM060L and one receiver RE060AUTOL. In addition to a cross stack optical monitoring path, the ER060AUTOL provides automatic calibration function.

  • Page 9: Technical Specifications

    The inner diameter of the cell is 2” (53 mm) and the length is approximately 130mm. The temperature controller, TC100, is located on the control unit. The optical fiber is leading the captured light to the Opsis analyser unit, which by those means can be protected from high temperature, dust, humidity etc.

  • Page 10: Stack Port Connections - Port Installation Kit

    ER060AUTOL is a cross stack monitoring unit. Emitter and receiver are mounted on op- posite sides, on 1 1/2” pipe socket connections. The recommended mount is a port kit sup- plied by Opsis which includes set of 4” ANSI flanges that are attached to the stack/duct walls.

  • Page 21: Safety Precautions

    Warning: This is a Class 3A (EC Standards) Laser Device. Caution should be taken when working with the equipment. At all work near the emitter and receiver or with the optical fibre cable connected to the LD500 analyser, safety goggles or eye protection should be used.

  • Page 22: Cu004/Cu007

    Safety precautions • The polished ends of the fibre are very sensitive to dust and dirt. Ensure that they are protected at all times. If they should need to be cleaned, a soft cotton cloth or lens tissues may be used, with a little alcohol if necessary. Never touch the ends of the fibres with your fingers, and do not use fabrics containing synthetic fibres for cleaning.

    Installation 5.1 Placement conditions for the emitter/receiver Make sure that there is enough space for the emitter/receiver. The emitter/receiver must be mounted horizontally. The maximum angle is 15°. The emitter and the receiver must be mounted with a clear line of sight between them.

  • Page 24: Placement Conditions For The Analyser

    Installation 5.2 Placement conditions for the analyser The analyser must be placed in an air conditioned and heated instrument cabinet. One 230 V (115 V), 10 A socket must be located in the proximity of the analyser cabinet. If there are any doubts that the 230 V (115V) is not free from surges, the analyser has to be pro- tected with a surge suppressor or an Uninterruptible Power Source UPS.

    1.5 m optical fibre. There are three ways to operate the LA060: Use it to visually align the transmitter and receiver. Use the ordinary measuring fibre to transfer light level information from the LD500 into the LA060 display. This simplifies light alignment (at the transmitter site) for long measuring paths.

  • Page 28: Visually Alignment Of The Transmitter And Receiver With The La060

    Connect the optical fibre included in the kit. Then connect the other end of the fibre to the optical transmitter. Put the ordinary fibre from the LD500, into the right con- nector of the LA060.

  • Page 29: Measure Light Throughput To Ensure Status Of Fibre Or Light Transmitter (Version 1.2 And Up)

    If there is a question of the quality of the optical throughput, use the LA060 to measure the intensity of the light. Connect one end of the fibre into the LD500 laser output, the other end into the upper right connector on the LA060. Depending on the output intensity of the laser, readings of 30-60 dB are normal.

  • Page 31: Multiplexers And Demultiplexers

    Splitting multiplexers and demultiplexers are used when several measuring path are co- trolled by one LD500 analyser or several gases are measured. Figure 7.1. Splitting multiplexer MX10nL or demultiplexer MXn01L. Note: When ordering a splitting multiplexer or demultiplexer, the laser module type must be specified.
