2x3A
The SKU.1.1 CG-S 2x3A circuit change over module is suita-
ble for snap mounting on the DualGuard-S module subrack,
supplies and monitors emergency lights with electronic
ballast for DC operation via two circuit feeders. CEWA
GUARD monitoring checks the function of the connected
emergency lights. It is possible to connect up to 20 emer-
gency lights. Mixed operation within a circuit of maintained
light, switched maintaineds light and non-maintained light
is possible with STAR technology. An additional data cable
is not required for SKU.1 type CG-S.
The individual switching of the emergency lighting circuits
enables separate fusing of the battery and mains supply
of the emergency lighting so that in the event of a simple
earth fault and failure of the mains fuse, the battery can
continue to be supplied via the IT grid. The arrangement of
the circuit fuses on the front of the module makes it easy
to replace them in the event of a short circuit or overload.
The LED on the front of the unit automatically reports total
faults which are indicated in detail on the HMI. Thus one
receives very comfortably all necessary information.
In addition, the generously designed ventilation slots ensu-
re optimum air circulation and heat transport. An automatic
insulation fault search in combination with the BCM.1
module and the colour touch screen makes the initial com-
missioning considerably easier.

Current value monitoring is possible, but should only be
used in exceptional cases where individual monitoring is
not possible for technical reasons. It must be ensured that
the failure of a single light is detected which is difficult with
lights with low power consumption such as LED lights due
to the supply voltage and ambient temperature fluctuations
of the light. It is not possible to precisely locate individual
defective luminaires.
