DESCRIPTION
FUNCTIONAL DESCRIPTION
The control console of the Composite Sampler provides the
operator interface for programming, control and charging of the
sampling system. The DSP in the control console scans the
keypad, communicates to the display, communicates with the
integral pump drive, assesses the state of and controls
charging of the battery.
The system is preprogrammed with one (1) fluid transfer
program and five (5) sampling programs. All of the factory-
supplied sampling programs can be modified by the operator
and saved without modifying or destroying the factory
supplied programming. The factory supplied programming
and operational parameters are stored in non-volatile flash
memory within the DSP controller.
Program options and instructions from the operator are
stored in non-volatile memory consisting of an EEPROM
which supplements the flash memory of the DSP.
CONTROLS, INDICATORS AND
CONNECTORS
All the controls, connectors, and indicators on the controls
console and exterior housing are shown in Figure 2 and 3.
Table 2 lists all of the operator controls and indicators.
