Emergency Luminaire eLLK 92 NIB

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.
