Battery
The inverter SWR 150 gets supplied by two voltage
sources, during mains operation from mains and during
mains failure from the battery. The mains voltage gets
supplied either via backplane or per module. The second
voltage source is a 216V-battery and supplies the SWR150
during mains failure, function fest or duration test.
According to the switching mode the output voltage of
the inverter is 230V for error-free mains and for mains
failure the transformed battery voltage in the form of a
sinus-AC voltage!
The frequency of the sinus-AC voltage can be adjusted in
the region of 50 to 140 Hz. If luminaires with conventional
ballasts are taken for safety lighting this ballast is used as
a voltage divider.
Therefore, the luminous flux of the lamp can be changed
depending on the adjusted frequency.
150 Hz ≈ 25 - 35% luminous flux acc. to type of lamp (s.
table)
50 Hz ≈ 100% luminous flux
The SWR 150 gets supplied with a maximum current
deviation of +/- 5% factory set.
The setting of this current deviation has to be entered in
the menue „5.3 Monitor mode“, minimum 15% - acc. to
number of types of luminaires and luminous flux.
Furthermore the currents have to be measured and saved
as written in „5.5 Learn currents“. An error is detected
from a battery current difference of at least 200 mA.
IMPORTANT NOTE:
During current-value-monitoring please observe that the
current input of CCG luminaires (conventional control
gear) in battery mode can vary significant caused by
ageing. Environmental conditions can also affect the
current input of luminaires in battery mode. (e.g. ambient
temperature)
In consequence it is necessary to re-calibrate the
current-value-monitoring from time to time (s. menu 5.3).
Otherwise a failure message is possible.

The
Safety lighting in maintained mode
operates
permanently being supplied by the central power supply
until the deep-discharge protection of the battery is
achieved, but at least until achieving the rated operating
time. In this switching mode the safety lighting cannot be
started.
The mains voltage of the
device gets supplied via
backplane by installed
bridge
