8 Theory of Operation
Fan Drive
The operation of the fan is controlled by the main processor and runs with
constant revolution. The fan produces a sense signal which is derived from the
revolution. This sense signal is used for diagnostics.
On-board Battery
An on-board lithium battery buffers the electronic memory when the module
is turned off.
For safety information on lithium batteries see “Lithium Batteries
Information" on page 335.
Analog Outputs
There are two independent analog outputs (0…1 V full scale). Digital data from
the ASIC is converted into a pulse-width modulated signal (PWM). The PWM
signal is then fed to an amplitude modulator, which precisely turns the
reference signal on and off. This signal then passes to a low-pass filter section.
Interfaces
For detailed information on interfaces, see “Interfaces" on page 285.
