Power Management
The Power Management processor is directly responsible for all the functions that
have to do with the incoming power voltage, as well as with the voltage supply to the
individual modules.
The Standby switch has to be monitored to prevent data loss. The power manager
makes sure, that all actual settings are stored in the EPROM after switch-off the 5017
with the Standby.
In addition, the power manager organizes the activation and deactivation of the LCD
and the adjustment of the LCD’s contrast.
Other processors
The
Front Panel Controller
assigns the appropriate functions to key presses on the
front panel.
The
Analog Module’s Processor
collects the accumulated measurement values, ac-
counts for calibration and offset factors, takes care of filtering signals, and finally
passes the data on to the main processor.
Switching of measurement points (80 x 1-pole, 40 x 2-pole, 20 x 4-pole) is carried out
by the
Controller on the Scanner Board
. This processor receives its information
about activation/deactivation of relays, and especially about timing, in part from the
main processor, in part from the controller of the Analog Board.
