20 ACU Module
20 ACU Module
The ACU (Advanced Control Unit) forms the interface bet-
ween the circuit switches (SKU.1‘s), the phase monitors
(3-PM, 3-PM-IO and 3-PM-IO-INV modules), the battery
block monitoring, the charging technology, the networking
with substations, the touch display, the web connection
and the VisionGuard visualization. Furthermore, the ACU
offers four potential-free signalling contacts as changeover
contacts with separate roots whose functions are freely
programmable in order to forward status messages such
as power failure, emergency lighting fault or battery fault to
a higher-level building management system.
In order to start a function test via a higher-level control
system or to switch all luminaires from ready light to con-
tinuous light or to connect analog phase monitors, eight
interrupt and short-circuit-tolerant 24V current loop inputs
are provided as standard.
The assignment of which action is to be executed is freely
programmable.
Via the internal ACU CAN Bus a networking of up to 32
LoadStar-S devices is possible to forward actions assigned
to one device to all devices.
Example:
The lamp which is connected to device 1 can be assigned
to the phase changer which is connected to device 32 via
the ACU bus.
All device information is securely transmitted to any place
in the world via the web connection. Furthermore, all confi-
guration and programming work can be done via the web.
