3.9 Inspection and Maintenance
On battery models, we recommend that the battery duration is checked periodically.
Important:
Isolate the mains supply and disconnect the battery terminal before carrying out any work.
3.9.1 Replacement of Electronic Ballast and EM convertor Unit
(Where Fitted)
The electronic ballast and EM convertor contain no replaceable parts. Should it be found necessary to replace
these parts, the following procedure should be adopted:
Ensure that the Luminaire is isolated from both mains and battery supplies, otherwise a risk of shock may occur.
Disconnect the leads on the ballast at the terminal block. Undo the ballast securing screws and washers and
withdraw the ballast from the gear body. Replace in reverse order. Replacement of the EM convertor is identical.
3.9.2 Routine Examination
The Luminaire must be de-energised before opening. Individual organisations will have their own procedures.
What follows are guidelines based on our experience :
1
Ensure LED’s are lit when energised by mains supply.
2
Visually check diffuser cover for damage, this should only be cleaned using a damp cloth to avoid static, and
only use recommended detergents for polycarbonate. If the polycarbonate is discoloured or damaged a new
diffuser cover must be fitted.
3
When de-energised and left to cool, there should be no significant sign of internal moisture. If there are any
signs of water ingress, the Luminaire should be opened up, dried and any likely ingress points eliminated by
re-gasketting or other replacements.
4
Check cable gland for tightness and nip up if required.
5
Check any external and internal earths.
6
Check all terminations are firmly screwed down, tighten if necessary.
7
Check clips visually for any damage and replace, if necessary.
8
If it has been suspected that the Luminaire has suffered mechanical damage, a stringent workshop check on
all components should be made. All components can be removed from the Luminaire for inspection.
4.0
Electrical Fault Finding and Replacement
The supply must be isolated before opening the Luminaire.
Any live fault finding must be done by a competent electrician and, if carried out with Luminaire in place, under a
permit to work.
The control gear can be tested for continuity of connections with a low voltage tester.
If LED’s go out repeatedly, and replacement components do not work or expected life is reduced, the control
gear should be returned for replacement / testing.
On re-assembly all faulty / damaged wiring should be replaced and connections checked.
5.0
Disposal of Material
The unit is made from combustible materials. The control gear contains plastic parts and polyester resin. All
electrical components and the body parts may give off noxious fumes if incinerated. Take care to render these
fumes harmless or avoid inhalation. Any local regulations concerning disposal must be complied with. Any
disposal must satisfy the requirements of the WEEE directive [2012/19/EU] and therefore must not be treated as
commercial waste. The unit is mainly made from incombustible materials.
5.1
LED’s
LED’s in modest quantities are not "special waste". They should be broken up in a container to avoid injury.
Avoid inhaling dust.
5.2
Battery Disposal
Nickel cadmium batteries are defined as 'controlled waste' under the hazardous waste regulations and disposer
needs to observe a 'duty of care'.
Batteries can be returned to the manufacturers for re-cycling. They must be stored and transported safely and
any necessary pollution control forms completed prior to transportation. Take care to fully discharge batteries
before transporting, or otherwise ensure that there can be no release of stored energy in transit. For further
details refer to our Technical Department.
