4. Function
Display
The battery 2710-3 fitted to the front of the
emergency light fitting is fitted with a microcom-
puter for charging and monitoring and with a
display composed of 6 light emitting diodes (fig.
1). The five green LED's indicate the battery's
charge state and available capacity. The red LED
signals possible failures (fig. 2 and 3).
Automatic function test
Function test (FT)
A function test (FT) is performed automatically.
During this process the emergency luminaire is
switched to battery supply for approx. 5 min. and
tested.
Partial operating time test (TBT)
Every 3 months a partial operating time test is
performed. If no emergency lighting operation >
30 min. has occurred during the last 3 months.
During this test emergency lighting operation is
performed for approx. 35 min.
Charging
The microcomputer controlled charging system
measures the charging and discharging current
and transmits it to a capacity meter. Five green
light emitting diodes indicate in 20%-steps the
actual charge state of the battery, see fig. 2.
Overcharging is prevented by means of this
charging control dependent on the capacity. Only
the energy drawn is recharged. The so-called
memory effect is thus also prevented.
At temperatures below -5°C and above +30°C the
battery will not be fully charged for
electrochemical reasons.
During the charging process the leading flashing
LED indicates the amount of capacity charged so
far. The LED's for the capacity already charged
indicate continuously (fig. 3). The charging
process is complete when all five green LED's are
illuminated and none is flashing.
The LED display takes into account the decline in
the capacity of the battery: i.e., if the indication
does not go beyond the 3rd green LED even after
an extended charging period, the available
capacity is between 40 and 60%.
This indication is updated again on each
emergency lighting operation until the battery is
shut down by the deep discharge protection for
the battery.
The reduction in the battery capacity due to self-
discharge in normal operation is automatically
recharged controlled by the microprocessor .
Emergency lighting operation
The duration of emergency lighting can be set to
either 1.5 or 3 hours, see eLLK 92 / eLLS 08 NIB
operating instructions (300 8000 1455).
Emergency lighting operation is automatically
initiated by the FT+TBT, by mains failure, or
manually by shutting down the mains supply.
During this process the emergency luminaire
marked in red is switched to battery operation.
