SpaceCover
The SpaceCover is connected to a SpaceStation with connector
“D1”.
With the SpaceCover standard this connector is used to connect
the CAN bus and a serial interface.
In the SpaceCover comfort this connector provides the voltage
supply, transmits a unique address in the Space system via a serial
interface, transfers data via a bus system (CAN bus) and transmits
a staff call, which may be pending.
The internal electronics controls the operator and status display
field, the loudspeaker as well as the status and alarm display line.
The status and alarm display line displays the collected messages
of the pumps in a column. The brightness is controlled dependent
on the environment.
The voltage supplied is converted to the internal voltages required
through a voltage transforming and monitoring circuit on the
processor PCB.
An independent circuit in the battery module monitors the battery
cells and controls their charge condition.
