a) VariantI(withoutterminalbox,incl.connectingcable) - The connecting cable has been factory-installed in the luminaire and is ready for use. - The external protective conductor terminal (1) should be connected to a separate operational earth. - The connecting cable should be supported after a max. distance of 1 m from entry gland. - Caution: If the cable is to be replaced (e. g. by one of a different length), the internal terminals have to be disconnected before unscrewing the cable entry gland. Specialconditions: Ex-type luminaires that do not have a terminal box are manufactured with a permanently connected cable. If connection is carried out in a potentially explosive environment, the free ends of the connecting cable must be installed in a category 2G/2D enclosure. Prior to installation and when servicing the luminaire without a terminal box, the luminaire and the surroun- ding area should first be cleaned to remove any dust. During installation or servicing, the disassembled parts should be protected against dirt and dust. Before closing the lamp again, it is essential to take extra care and ensure that the inside of the luminaire is free of dust.

b) VariantII(withterminalbox) - Select a connecting cable to fit the cable entry gland M20 x 1.5. If the ambient temperature is greater than 40°C, heat- resistant cable, e.g. Sinotherm 110 H05GG-F3G 1.5 mm² should be used. The minimum heat resistance of the connecting cable is shown on the type plate, if applicable. - Open the cover of the terminal box. - Loosen strain relief screws with anti-twist tabs on the cable gland assembly. - Insert cable, seal, tighten screws again.

a) Variant I – Ex d without terminal box, including connecting cable

•Electricalconnection:

- Wire to Ex terminal block (6); max. cross-section 2.5 mm²; protective conductor to terminal (5, internal). The external protective terminal (1) must be connected to a separate operational earth. - Check that the gasket is in the correct position in the cover; adjust if necessary! - Close lid of terminal box, making sure the gasket is in place. •Replacinglamp: - Switch off power - Allow sufficient time to cool down, see type plate. - Undo locking screw (2) which releases the safety tab (3) for the screw-type glass lens (4). - Unscrew glass lens (4) using only the special claw spanner. - The defective lamp is then pulled out (2-pin type), or removed with a press-and-twist movement (GZ10 bayonet type). - Hold the new lamp bulb (original products only, please) using a protective cloth, taking care not to touch it with your bare fingers. Carefully insert the replacement lamp: push the 2-pin bulb into its socket, push-and-twist bayonet type lamps. Make sure the lamp is securely in position! - Before closing the luminaire, re-lubricate the thread of the screw lens (e. g. with AEMA-SOL 6 B, from A. E. Matthes). - Refit the glass lens (4) by screwing it into place until it is tight again (pressure on O-ring). - The glass lens (4) is locked into position once the safety locking tab (3) engages in one of the notches. - Retighten the locking screw (2). - Switch on power again.

•Warning: When replacing lamp bulbs, make sure that the light beam is evenly distributed over the glass lens as prescribed by the design. On no account should a “hot spot” be allowed to occur outside the luminaire (caused e. g. by the incorrect position or condition of the lamp).

Important guidelines for mounting and use of sight glass fittings, toughened glasses and luminaires:Before installation and operation/servicing, please read and follow all commissioning and servicing instructions.

1. Installation of sight glass fittings The installation by welding, brazing etc, must be free of distortion

and thus carried out by suitably qualified and authorized personnel.

2. Installing toughened glass discs into a sight glass assembly2.1 Operating safety of sight glasses depends to a great extent upon their

correct installation.2.2 The gasket seating surfaces in the flanges must be plane, flat and

smooth. Ensure the gasket edges are not trapped by, or foul, the flange gasket recess wall.2.3 The glass disc, with gaskets appropriate to the process application fitted to its top and bottom faces must be located concentrically in

the flange assembly.2.4 Only use gaskets which are in good condition, flat and free of dirt

and grease.2.5 Before tightening nuts or bolts ensure once more that cover and base

flanges are correctly aligned and surfaces parallel to one another.2.6 Tighten the nuts or bolts progressively in diametrically opposed pairs.

Tightening moments can be obtained from the relevant data sheets accompanying product (or consult supplier).

2.7 Further tightening down may be required after assembly has bedded down under operating temperature and pressure.

2.8 When installing quartz sight glass discs follow manufacturers’ instructions!

3. Max. loading of toughened sight glass discs3.1 Correctly fitted sight glass discs must be used within the working temperature and pressure ranges laid down for them otherwise they

may fail.3.2 Temperature cycling to be within permitted limits: •Sodalimeglass(DIN8902),maxpermissibletemperature:+150°C. Temperaturechangewithinoneminutemaxfrom120°Cto20°C

with glass fully immersed. •Borosilicateglass(DIN7080),maxpermissibletemp.:+280°C. Temperaturechangewithinoneminutemaxfrom230°Cto20°C

with glass fully immersed.3.3 Avoid spraying sight glasses which are still hot with cold fluid. Warning! This can lead to glass disc breakage.3.4 Safety Precautions when using sight glass discs: 3.4.1 Scheduled Maintenance: Sight glasses must be included in preventive maintenance, and regularly checked either visually or by ultra sound measurement of

wall thickness. Where a disc shows any damage it must be exchanged promptly with the plant shut down. Further, a thorough and regular check of the sight glass should lead to a down time to suit the

par ticular vessel; this will promote a routine for glass exchange suited to the process.

3.4.2 Breakage of glass disc: Inspiteofcarefulfittingandoperationinaccordancewithinstruc-

tions, it is possible though rare, that due to external effects a glass disccanfail.Itisnecessary,particularlyinthecaseofcriticalprocessessuch as in the food industry, that the plant manufacturer or operator takes appropriate safety measures to prevent glass fragments finding their way into the product.

3.5 After dismantling a sight glass assembly, and in accordance with DIN7080standardrequirementsforalltypeofsightglassdisc,the

glass disc and gaskets are replaced with new ones before the assembly is put back into operation. This is particularly important

where pressure vessels and/or aggressive media are concerned. ThefollowingwordingasextractedfromDIN7080refers: “Sight glass discs may only be installed by personnel who are thoroughly versed about the following requirements: •carefultreatmentofsightglassdiscs •cleaningofrecesses,discs,gasketsandaccessoriespriortoinstalla-

tion, i. e. the removal of foreign matter (e. g. machining swarf); •eventighteningupofholdingdownbolts. Sight glass discs removed from assemblies following operational service may not be reused.”

4. Sight glass wiper4.1 Check that wiper assembly is correctly installed (see separate installa tion instruction)!4.2 Wipers may only be used within temperature and pressure ranges specified.4.3 Drive/spindlehousingshouldbeperiodicallycheckedtoensureagood

seal; if necessary tighten threaded bushes/glands, replace defective seals, clean wiper arms and blades to remove accumulated foreign matter or replace (see installation instruction).

5. Spray device The spray fluid temperature should be as near as possible to that of

vessel contents. On no account use cold spray fluid on hot glass disc (see ‚temperature cycling‘ under point 3).

6. Sight glass luminaires6.1 Always ensure that luminaire is connected to correct supply voltage as

indicated on identity plate.6.2 All luminaires are purpose designed and exclusively made for moun-

ting onto flanged sight glass assemblies.6.3 Never use the luminaire in place of cover flange or a complete sight

glass fitting.6.4 Only certain models of luminaire may be used in con tinuous ON

mode; please check before confirming order; if in doubt ask supplier or manufacturer.

6.5 Luminaires with built in ‚non maintained‘ switches are for intermit-tent use and may only be operated with those switches.

6.6 Luminaires intended by the user for continuous ‚ON‘ mode operation should be controlled by separate external ON/OFF switch.

6.7 The following should also be noted •Max.permissibletemperatureatcableentrynottobeexceeded (see data sheet). •Max.permissibletemperatureofglassnottobeexceeded(Vessel

temperature + temperature increase caused by luminaire = sight glass temperature; check by measurement!) 6.8. When replacing lamps use identical type with identical power rating;

never exceed max. permissible lamp rating recommended for any given luminaire.

6.9 When changing lamps, check condition of lamp socket as a matter of course.6.10 Excessive voltage will shorten lamp life.

7. Ex Hazardous areas Ex hazard rated luminaires must not be installed or serviced other

thanbysuitablyqualifiedandauthorisedpersonnel.Dataand instructions contained in relevant approval test certificates (certifi-

cates of conformity) must be adhered to. Some Ex luminaire models are works fitted with permanently encapsulated (resin cast) cable tails; on no account attempt to unscrew or remove cable entry gland! Any inappropriate change in components of Ex certified luminaires can render the relevant certificate invalid.

8. Hinged or screwed sight glass assemblies Before use, ensure the seals are functioning (if necessary tighten securing nuts/bolts). The seal between hinged ports and vessel flange is en sured by correctly seated components; flanges to mate up parallel by correctly

adjusted swing-bolt/hinge assembly and undamaged, clean seals free of grease.

Inthecaseofhingedunits,ensurethematerialofthehingedglassserround is compatible with vessel contents. When used on pressure vessels, ensure max. operating pressure specified for the sight glass is exceeded.

If in doubt, consult supplier or manufacturer!
