Explosion Proof Emergency Light Fitting |
The new Ex-emergency light fittings
with self-contained battery unit, types
eLLK 92… NIB, for bi-pin fluorescent lamps
are fitted with an electronic ballast (EVG).
They meet the requirements of ATEX
Directive 94/9/EC. The electronic ballast
EVG 05, according to the newest standard
(IEC 60079-7:2006) enables the safe and
economic use of G13 bi-pin lamps acc.
to IEC 60081. Lamps are monitored and
safety shut down at the event that the lamp
does not strike. Due to a new charging
and monitoring technology with intelligent
microelectronics, they provide reliable
safety and reduced maintenance costs.
A function test lasting 5 minutes, that is
carried out automatically on a weekly
basis, even during mains operation, and
a quarterly partial duty-cycle test provide
additional safety and drastically reduce the
necessaary amount of manual tests. The
charging and discharging funtions are
monitored constantly by the micro-processor
and are indicated via a diode display. Only
the spent energy is recharged – therefore,
overcharging is not possible. The so-called
memory effect cannot occur – the service
life of the battery is optimized. The need to
replace a battery, a fault in the emergency
lighting circuit or a faulty battery is indicated
by the LED display. Due to a new type
of battery connection, the battery can
be replaced in the hazardous area. The
emergency lighting cycle can be set locally
for 1.5 or 3 hours. A remote switch inquiry
is standard.
