• Parameters/Temperature classification:
• Mounting with hinged bracket:
The hinged bracket is used to secure the luminaire to the
cover flange of a circular sight glass unit (also suitable for
flow indicators). Alternatively, it can be attached to the
slotted cover nut of screw-type sight glass fittings to
DIN 11851.
The bracket is fixed in place by turning the supplied ‘M8‘
bolt into a blind hole which has previously been tapped in
the pitch circle of the cover flange face. An additional
option is to weld the bracket on.
• Mounting with flanged adapter collar:
The flanged adapter collar fits between the glass disk and
the slotted cover nut (DIN 11851):
- Position appropriate seal between glass face and the
flanged adapter collar
- Tighten the slotted nuts
- Insert the luminaire into the flanged collar
- Please note: The Lumiglas luminaire variant for sterile
technology is slipped over the collar of the sterile
technology flange.
- Please note: Please order fastening and mounting
elements, claw spanner, etc. separately if not available.

• Electrical connection:
a) ESL 25-Ex with cable tail
- The cable tail is already works-fitted in the luminaire and
is ready for use.
- The external protective terminal (2) must be separately
earthed.
- The cable tail should be supported after max. 1 metre.
- Caution! When replacing the cable (e. g. by one with a
different length), ensure the internal connections have
been loosened prior to unscrewing the cable gland.
Special operating conditions:
Ex-category luminaires have been manufactured with a fixed
connecting cable.
If the terminals are in a potentially explosive environment,
the free ends of this cable must be installed in a flameproof
housing category (2G/2D). Prior to installation and when-
ever the luminaire is being serviced, please remove all dust
from the luminaire and from the area surrounding the
place of installation.
The dismantled parts should be protected against dust and
dirt during all installation or maintenance work.
When closing the luminaire, please take special care to
ensure that the interior of the luminaire is free of dust.
b) ESL 25-Ex with cable entry gland
- Select an M20 x 1.5 connecting cable to fit the cable
entry gland.
- If ambient temperatures are 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
specified on the type plate (where applicable).
• Replacing lamp:
- Disconnect the luminaire.
- Allow sufficient time to cool down, see type plate.
- Undo locking screw (3); this releases the safety tab (4) for
the screw-type glass lens (6).
- Unscrew glass lens (6) using only the special claw spanner.
- Pull out the defective light bulb (2-pin type).
- Hold the new lamp (original products only, please) using a
protective cloth, taking care not to touch it with your bare
fingers. Carefully insert the replacement 2-pin bulb into its
socket, making sure the lamp is securely in place!
- Refit the glass lens (6) by screwing it into place until it is
tight again (pressure on O-ring).
- The safety tab (4) has to engage in the notch provided to
ensure that the glass lens (6) is locked in position.
- Retighten the locking screw (3).
- Switch on power again.
• Warning:
When replacing light bulbs, make sure that the light beam is
evenly distributed over the glass lens. On no account should
a “hot spot” be allowed to occur outside the luminaire
(caused e. g. by the incorrect position of the lamp or the
wrong type of light bulb).
• Please note:
Please order mounting parts and claw spanner separately
if needed.

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 assembly
2.1 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 discs
3.1 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:
 •Sodalimeglass(DIN8902),maxpermissibletemperature:+150°C.
Temperaturechangewithinoneminutemaxfrom120°Cto20°C 
with glass fully immersed.
 •Borosilicateglass(DIN7080),maxpermissibletemp.:+280°C.
Temperaturechangewithinoneminutemaxfrom230°Cto20°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:
 Inspiteofcarefulfittingandoperationinaccordancewithinstruc-
tions, it is possible though rare, that due to external effects a glass
disccanfail.Itisnecessary,particularlyinthecaseofcriticalprocesses
such 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
 DIN7080standardrequirementsforalltypeofsightglassdisc,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.
 ThefollowingwordingasextractedfromDIN7080refers:
“Sight glass discs may only be installed by personnel who are
thoroughly versed about the following requirements:
 •carefultreatmentofsightglassdiscs
•cleaningofrecesses,discs,gasketsandaccessoriespriortoinstalla- 
tion, i. e. the removal of foreign matter (e. g. machining swarf);
 •eventighteningupofholdingdownbolts.
Sight glass discs removed from assemblies following operational
service may not be reused.”
4. Sight glass wiper
4.1 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/spindlehousingshouldbeperiodicallycheckedtoensureagood
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 luminaires
6.1 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.permissibletemperatureatcableentrynottobeexceeded
(see data sheet).
•Max.permissibletemperatureofglassnottobeexceeded(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
thanbysuitablyqualifiedandauthorisedpersonnel.Dataand
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.
 Inthecaseofhingedunits,ensurethematerialofthehingedglass
serround 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!
