4.0 Overhaul
The unit is largely made of materials which are very corrosion resistant. This allows the unit to be completely stripped,
cleaned then re-built with new electrical components as required. All spares required are available. Please state the model
number, lamp and reflector details. The seal at the cover is between the glass and the body. The glass is retained in the
cover frame by silicone R.T.V. adhesive. If the cover gasket has deteriorated a new cover assembly should be fitted, which
can be obtained from Victor.
4.1
Fuse Ratings
The fuse ratings for HID lamp circuits need to take account of three components of circuit current. Current inrush to PFC
capacitors which can be up to 25 x the rated capacitor current, and last 1-2 milliseconds. Lamp starting current including
steady capacitor current which together may decline from up to 200% of normal at 10 seconds after switch-on to normal after
4 minutes; rectification effects caused by asymmetrical cathode heating for a few seconds after starting, this effect is random
and very variable.
With the availability of MCB's with a wide range of characteristics, the individual engineer can make a better judgement of
what is required. Use MCB's suitable for inrush currents to reduce ratings. The normal capacitor current, will probably be the
determining factor, 0.076A per
μ
F at 240V, 50Hz (adjust for other volts by multiplication, x 6/5 for 60Hz). For HBC fuses use
1.5 x normal capacitor current. For GLS inrush use 6 x rated current. All calculations must satisfy wiring regulations.
Note :
S
tarting and running currents for 240V, 50Hz are as indicated in TABLE 1.
A conventional matrix for HBC fuses is shown in TABLE 2.
5.0
Disposal of Material
Any disposal must satisfy the requirements of the WEEE directive [2002/96/EC] and therefore must not be treated as
commercial waste. The unit is mostly made from incombustible materials. The control gear contains plastic, polyester resin
and electronic components. All electrical components may give off noxious fumes if incinerated.
5.1
Lamps
Incandescent lamps and discharge lamps in modest quantities are not "special waste". The outer envelope should be broken
in a container to avoid possible injury by fragmentation.
This applies to the UK, there may be other regulations on disposal operating in other countries.
Important :
Do not incinerate lamps.
5.2
To comply with the Waste Electrical and Electronic Equipment directive 2002/96/EC the apparatus cannot be
classified as commercial waste and as such must be disposed of or recycled in such a manner as to reduce the
environmental impact.
