1 Overview of the Device
Infusomat® compact
plus
P 1.0 1 - 3 EN
For internal use, only
FUNCTION Power supply
There are several ways of powering the Infusomat® compact
plus
P:
■
via the built-in battery module,
■
via an external 12 V DC power supply cable connected at the
connector (e.g. from an ambulance),
■
via line voltage and the integrated power supply unit, or
■
via the Station compact
plus
.
The voltage supplied is converted to the required internal voltages
in a voltage transforming and monitoring circuit on the processor
board. The processor board monitors the battery cells and controls
their charge condition.
Processors
The function processor controls all the functions of the Infusomat®
compact
plus
P. Data is stored in a non-volatile memory. External
data transmission is also controlled from here. The monitoring
microprocessor monitors all important responses of the function
processor to incoming information. If a response does not
correspond to that expected by the monitoring microprocessor, an
error message is generated and the device is switched to a safe
state (stop plus alarm).
User interface
The display is illuminated.
