2.5.2 Electronic interfaces
This section describes the pinning, function and significance of the signals on the internal
interfaces of the functional components.
2.5.2.1 Interface to the switching power supply
The interface to the switching power supply is realized by the connector POSUP/ on the
PCB Control CS CI.
Connector denotation: POSUP/
Type: male connector 1 X 4-pin., 180°, AMP MODU |
reverse terminal protection achieved mechanically.
The function of the individual pins is given in the following table . The definition as an
input/output is seen with reference to PCB Control CS Cl.
POSUP/
Pin Signal Name input/output | Function Definition
Number
1 +24VPS Input Voltage from power sup. | + 26,5V
2 +24VPS Input Voltage from power sup. | * 26,5V
3 GNDPS Input GND from power supply
4 GNDPS Input GND from power supply
2.5.2.2 Interface to the PCB NC battery charge
