Advices
to follow carefully installing Kits
(Ballast + Ignitor) INSTART Systems.
WIRING ADVICES
The
Ballast output marked with the symbol
is generally called “hot terminal”,
as to this terminal is connected the wire which transfers the high-voltage
pulses to the lamp (see fig.3).
For the connection, use an high insulated cable, silicone rubber
coated or with double coating.
Photo Electronics can supply it in bobbin or cutted at the required lenght
and already with connector provided with a silicone cup.
Besides, keep this cable as short as possible to avoid striking
pulses attenuation and radio frequency noise emission. The remaining
wiring doesn’t need other particular warnings to observe.
Particular
attention must be paid to the following aspect:
Furthermore
it must be reminded that in
case of non-ignition of the lamp, the system keeps on delivering a voltage
peak of some thousands of Volts.
Therefore, before making any intervention on the luminaire or on the
gearbox, make sure that main supply is cut out.
Like
for all electrical appliances,
the installation and replacement of ballast and ignitors must be performed
only by qualified operators.
LAMPS
Lamps which fit for the hot restrike systems, are double-ended
models, TS or D2 type, both Sodium High Pressure and Metal Halide,
which are normally produced by all lamps Manufacturers (Philips, Osram
...), or special models produced by VENTURE Lighting (USA), with E40/Mogul
socket and hot terminal wire coming out from the other side of the glass
jacket (top wire).
Normal lamps with E40 socket cannot be used, as they haven’t enough
insulation.
LAMP-HOLDER
On Hot restrke units is necessary to use highly insulated lamp-holder,
Rs7/Fc2 or similar, to avoid sparks and earthing discharges risk
during the lamp ignition period.
The best solution should be to mount a good quality lamp-holder over a 1mm
thick 60x80mm Teflon or mica foil, using also Teflon screws and nuts.
Some lamp-holders manufacturers can supply such special versions (such as
Bender & Wirth and Vossloh); however Photo Electronics can supply them
together with Warm Start power supply Kits, or will indicate where they
are available.
