2 Introduction

2.1System Overview

The Quasar 8100-EXP Pilot Monitor (PM), Flare Monitor (FM), and Smoke Monitor (SM) are unique monitoring and detection instruments designed for continuous duty monitoring of Pilot Flame, Flaring and Smoke on Flares.

The heart of the LumaSense E2T QUASAR M8100-EXP Flare Monitoring System is the non-contact infrared Electro-Optical package, which can be removed from the explosion proof housing for repairs or replacement, while leaving all wiring and alignment of the system intact

(see Figure 1).

Figure 1: M8100 Housing and Electro-Optical Package

E2T QUASAR Flare Monitors Operation Manual

Introduction 11

A sight-through optical system and selection of various optical resolutions (fields of view) enable the QUASAR M8100-EXP to be positioned as far as 1/4 mile (400 m) from the stack being monitored. Alignment on the target is accomplished using exceptional sight-through optics and the M-3 Heavy Duty Swivel Mount.

Figure 2: Quasar M8100-EXP

The electronics allow for target movement, varying luminosity and a range of climate conditions. The alarm contact closure delay can be adjusted for a specific location or application, eliminating false alarms due to intermittent flames, wind, and/or transitory high smoke levels. A single internally heated detector assures long-term stability and drift-free operation. The system is complete with internal cooling base, air purge tube and swivel mount. An optional adjustable pedestal stand allows for easy mounting.

2.2System Features

Features of the QUASAR M8100-EXP Flare Monitoring System are as follows:

Explosion-proof housing.

4-20 mA output.

The Quasar 8100-EXP PM & FM provide a switched 4mA (Flame) or 20mA (No Flame) switched mA output.

The Quasar 8100-EXP SM provides a mA span determined by the flame size of the target flaring event. (Note: every span will be different for different flare applications)

On-board ALARM set point with normally open N.O. and normally closed N.C. relay outputs. This Alarm Setpoint is delayed in the PM/FM from 2 seconds to 2 minutes. The SM system has no delay.

Climatic compensation adjustments.

An Electro-Optical package that is easy to remove from the explosion-proof housing, minimizing downtime and increasing reliability (see Figure 1).

An internal heater and water/air cooler cavity for ambient temperature compensation.

High quality sight-through optics.

Local status indication lights.

E2T QUASAR Flare Monitors Operation Manual

Introduction 12

2.3Principle of Operation

All objects above absolute zero emit infrared energy. The amount of energy emitted is proportional to the body’s temperature. The QUASAR M8100-EXP collects this energy by means of a focusing optical system concentrating the energy from a body onto a sensitive infrared detector. Specialized amplification circuitry converts the signal received by the detector into a DC level to activate relay and mA outputs for monitoring. The M8100-EXP utilizes amplitude correction circuitry which, when initially set, will automatically correct for diminishing radiation amplitude due to varying and/or adverse weather conditions.

2.3.1Alarm Set Point

PM/FM - If the instrument detects a loss of signal fault, an adjustable delay timing circuit starts a countdown to activate a “loss of signal” alarm. This delay circuit allows for loss of signal due to wind or adverse conditions for a time period of two seconds to two minutes. This allows the monitor to reacquire the flame before an alarm signal is sent, limiting false alarms due to weather conditions. The alarm provides status by LED and Relay contacts.

SM - The alarm set point has no delay and activates in real time.

2.3.2Relay Contacts

Denoted by their non-energized states, Normal Open (N.O.) and Normal Closed (N.C.) contacts are common to a single Relay Common (Com), also known as “single pole double throw” contacts.

4-20mA Outputs

PM & FM: 4 or 20mA circuit outputs 4mA or 20mA depending on a preset signal level. Standard output provides 4mA with a flame present, 20mA without a flame present. This is a switched output.

SM: mA circuit outputs a signal proportional to the relative amount of smoke detected.

2.4Signal Path

Infrared (IR) energy is focused onto the detector through a rotating chopper wheel. The chopper wheel provides the ability to stabilize and improve noise rejection. IR filters are employed for the FM, PM, and SM models. By virtue of these select, application-specific IR filters, the desired IR energy is allowed to pass and be amplified by the detector. Filters are located on the chopper wheel for the SM and are located on the detector for the FM and PM.

The rotating chopper wheel creates a pulsing (on/off) signal, which is then selectively amplified by the detector. The detector’s amplified signal is conditioned by chopper synchronized, automatic amplitude control and stabilization circuits. This allows for compensation for diminishing IR radiation due to climate conditions and is accomplished without operator intervention.

After the signal is conditioned, it is further filtered and provides the input to subsequent; relay driver, time delay and 4-20mA output control circuits.

2.4.1SM: Smoke Monitor’s Dual Wavelength (2 color)

Unique to the QUASAR M8100SM-EXP is the use of 2 filters at separate wavelengths or colors. These filters located on the chopper wheel, allow the electronics to selectively amplify the IR energy of interest over the background IR energy, thus allowing the Smoke Monitor to distinguish particulate (smoke) from the background flame that is present.

E2T QUASAR Flare Monitors Operation Manual

Introduction 13

2.4.2PM: Pilot Monitor’s Flame Sensitive Wavelength

The QUASAR M8100PM-EXP uses a single select filter allowing the electronics to amplify the IR energy of interests over the background IR energy. This allows the Pilot Monitor to achieve high sensitivity and dynamic range.

2.4.3FM: Flare Monitor’s Flame Sensitive Wavelength

The QUASAR M8100FM-EXP uses a single select filter allowing the electronics to amplify the IR energy of interests over the background IR energy. This allows the Flare Monitor to achieve high sensitivity and dynamic range.

3 Mechanical Installation

3.1Getting Started

Each LumaSense E2T QUASAR M8100-EXP instrument is configured as per customer’s request. The packing slip order number matches that of the instrument’s serial number. It is recommended to confirm that the instrument’s configuration meets expectation, by reviewing packing slip details.

Once you have determined the unit you received is the unit you ordered and it is in acceptable condition, the unit is ready for installation. It would be a good idea to spend a few minutes "getting to know" your QUASAR M8100-EXP.

Reference: Chapter 10 Safety Assurances and Precautions.

3.2Sight Assessment

Care must be taken during installation to ensure that the sun will not be seen through the optical sight path in any season or time of day. This requires that the instrument be located on a true north-south axis ± 45 °. In the northern hemisphere, the monitor preferably should be looking toward true north, while in the southern hemisphere it should be aimed toward true south. Contact LumaSense for exceptions to these standard installation parameters.

Figure 3: Field of View Concept

3.2.1Pilot Monitor (PM) Sighting

Recommended installation distance should be equal to the height of the flare stack from the base of the flare stack. The maximum vertical angle for sighting the monitor is 45 ° above horizontal. (See Appendix E Engineering Drawing 613-228.) Targeting should include the Pilot flames and have a spot size of 1.5x to 2x the flare diameter.

E2T QUASAR Flare Monitors Operation Manual

Mechanical Installation 17

Figure 4: Field of View Concept

3.2.2Flare Monitor (FM) Sighting

Recommended installation distance should be equal to the height of the flare stack from the base of the flare stack. The maximum vertical angle for sighting the monitor is 45 ° above horizontal. (See Appendix E Engineering Drawing 613-228.)

Targeting should be just above the pilot flames, so that they are not included in the measurement, or if this is not possible, then the gain should be reduced until the pilot flames are not detected. The spot size of the system should be 3x to 4x the flare tip diameter.

3.2.3Smoke Monitor (SM) Sighting

Recommended installation distance from the base of the stack is at least 1 to 2 times the stack height. The maximum vertical angle for sighting the monitor is 45 ° above horizontal. The field of view must be at least 4 to 5 times the stack top diameter when no wind is present.

3.2.4Mounting Options

For easy mounting, alignment, and focusing on the target, a swivel mount with locking and adjusting capability is provided (LumaSense’s M-3 Heavy Duty Swivel Mount). The M-3 Heavy Duty Swivel Mount can be secured on a pedestal base model M-8 using a telescoping steel pipe with a bolt down plate to secure the M-8 to a foundation. (See Figure 5) As an alternative, the M-3 Heavy Duty Swivel Mount can be installed on a client supplied 2-inch schedule 40 pipe mount.

3.3Ambient Temperature Limits

The ambient operating temperature limits of the QUASAR M8100-EXP are -40 °F (-40 °C) to 120 °F (50 °C). When the internal temperature drops below 40 °F (4 °C), an internal electric heater activates to keep the internal temperature at or above 40 °F (4 °C). If the ambient temperature is expected to be below -40 °F (-40 °C), additional heating or protection for the

instrument is required. If the ambient temperature is expected to be above 120 °F (50 °C), water or Vortex Air cooling is required.

3.4Cooling Requirements

If ambient temperatures in excess of 120 °F (50 °C) are anticipated during the operation of the QUASAR M8100-EXP, cooling will be required by one of the following two methods:

3.4.1Water Cooling

Provide cooling water at 60 °F (15 °C) maximum from a filtered source with a flow rate capable of sustaining at least 10 gallons per hour (37.8 L/h) to the cooling cavity built into the underside of the explosion-proof enclosure. This method allows operation in ambient temperatures up to 200 °F (93 °C). If the available cooling water temperature is above 60 °F (15 °C), then trial-and- error testing will have to be performed to empirically set the appropriate flow rate. The flow rate must be adequate to ensure that the electronics inside the explosion-proof enclosure do not rise above 120 °F (50 °C).

Note: The cooling cavity is isolated from internal surface of explosion-proof enclosure. See Appendix E Engineering Drawing 613-816, Service Connections.

3.4.2Vortex Air Cooling

Connect a V208-15-H Vortex Air cooler to the cooling cavity built into the underside of the explosion-proof enclosure. Provide filtered, dry, compressed air from a minimum 90 psig source with a sustained flow rate capability of at least 10 SCFM to the vortex air cooler. This will result in a temperature reduction up to 27 °F (3 °C) lower than the supply air. It is not necessary to over cool the instrument. Instead, reduce the enclosure temperature to its specified operating limits by adjusting the upstream pressure to the Vortex Cooler. If over cooling does occur, the heater built into the system will activate and keep the electronics within limits.

Note: The cooling cavity is isolated from internal surface of explosion-proof enclosure. See Appendix E Engineering Drawing 613-816, Service Connections.

3.5Viewport Air Purge Requirements

A source of sustained dry instrument air with a flow rate through a regulator or needle valve capable of sustaining 1 SCFM flow rate from a 20 psig or greater supply is required to keep the lens clean.

3.6Target Size and Focusing Range

The target size of the QUASAR M8100-EXP is a function of the distance from the lens to the object under observation and the optical resolution set at the factory. The target area is a circle reticle as viewed through the QUASAR M8100-EXP's sight-through optics. The diameter of the detection area (Target Size) is represented by the reticle circle and is calculated using the formula:

Target Size = D Where D = the distance from the lens to the target.

RR = the appropriate value from the following table

The resolution of the optics is applicationspecific and determined at time of order.

The objective lens locking and focusing screw and the eyepiece are both located on the top of the infrared electro-optical package inside the explosion-proof enclosure (see Figure 6).

To focus, first rotate the eyepiece lens (Figure 6, item 1) in or out until the reticle is clear and sharp. Next, slowly loosen the lens locking and focusing screw (see Figure 6, item 2). Move the objective lens (see Figure 6, item 3) in or out with the focusing screw until the target is clear and sharp. Tighten the screw; the focus is now set.

4.1Electrical Installation Guidelines

Be sure to reference Appendix E Engineering Drawing 613-816, Service Connections during this procedure.

4.1.1Conduit/Connections

Power and signal wires are fed through the 3/4 inch NPT conduit holes in the side of the housing. All wires exiting the enclosure must run through properly installed explosion-proof packing gland fittings to maintain the explosion-proof rating. Only a qualified service person should perform operations on this instrument.

Warning: The seal fittings must be located NO GREATER than 18 inches (457mm) from the instrument enclosure to maintain the explosion proof rating.

For II 2 G, EEx d IIB T4 applications, this seal must be directly at the enclosure entry.

LumaSense does not provide the explosion-proof packing gland fittings required for installations since client standards vary as to the brand or type of explosion-proof packing gland fittings required for installations. Additionally, states and countries have different standards, making it very difficult for LumaSense to stock the proper fittings.

Flexible conduit of sufficient length must be used from the housing explosion-proof packing gland fittings to the hard conduit or junction box to enable movement of the unit on the pedestal.

All power and signal connections are made on the Terminal Output board mounted on the infrared electro-optical package inside the explosion-proof enclosure. Power is connected to terminal block TB1. Output signals are connected to terminal block TB2.

See Chapter 10.2, Electrical Service Protection, for more information.

4.1.2Over-Current Protection/Service Switch

It is necessary to incorporate an external over-current protection device appropriate to the instrument’s service and to include a disconnect switch located near the instrument. The service disconnect should be clearly marked as pertaining to this instrument.

4.2Power Connections

Connect the input power as described in this chapter. Confirm service type and check that the instrument service markings correspond to expectations. When wiring, follow local code regulations. Secure power input conductors together after connection to terminal block to prevent an accidental hazardous live condition in the event a terminal screw becomes loose. Sleeve or tie wrapping is acceptable. Check to ensure power is not accidentally connected to the low voltage I/O terminal block TB2.

4.2.1Service Markings

Input Power service (i.e.120VAC, 220VAC, 24VDC) and Fusing type are factory set and marked on the Terminal Output PCB (See Figure 7).

4.2.2Protective Ground Connection

Connect the protective Earth conductor to the terminal lug located inside the housing as indicated by the symbol.

4.2.3Cover Attachment

Warning: At no time should the cover be removed unless power is switched off first. When it is necessary to service the instrument with the power applied, ensure that proper safe environmental conditions exist and that such maintenance is authorized and pursuant to safe conditions.

Reference Chapter 10, Safety Assurances and Precautions, during this procedure.
