DSP_BROWNOUT

NO

Display brownout is used to keep the display from

 

 

 

getting corrupted during low line voltage conditions.

 

 

 

Circuitry on the Status/Temp board senses low line

 

 

 

voltage and sets this bit. The CPU reads this and

 

 

 

generates the BROWNOUT_RST signal described

 

 

 

below.

 

 

 

 

1

EXT_ZERO_CAL

NO

Shows state of status input bit to cause the M200AU

 

 

 

to enter Zero Calibration mode. Use to check external

 

 

 

contact closure circuitry.

 

 

 

 

2

EXT_SPAN_CAL

NO

Shows state of status input bit to cause the M200AU

 

 

 

to enter the Span Calibration mode. Use to check

 

 

 

external contact closure circuitry.

 

 

 

 

3

SPAN_VALVE

YES

Switches the Zero/Span valve. Use this bit to test the

 

 

 

valve function.

 

 

 

 

4

CAL_VALVE

YES

Switches the Sample/Cal valve. Use this bit to test

 

 

 

the valve function.

 

 

 

 

5

NOX_VALVE

YES

Switches the NO/NOx valve. Use this bit to test the

 

 

 

valve function.

6

RCELL_HEATER

YES

Shows the status of the reaction cell heater. This has

 

 

 

the same function as the LED in the Power Supply

 

 

 

Module.

 

 

 

 

7

BLOCK_HEATER

YES

Shows the status of the block heater.

 

 

 

 

8

ELEC_TEST

YES

Turns on electric test bit on the preamp board. Should

 

 

 

be used for troubleshooting Preamp logic lines. We

 

 

 

recommend you use the ELEC TEST button in the

 

 

 

DIAG menu to operate electric test.

 

 

 

 

9

OPTIC_TEST

YES

Turns on optic test bit in preamp. Should be used for

 

 

 

troubleshooting Preamp logic lines.

 

 

 

We recommend you use the OPTIC TEST button in

 

 

 

the DIAG menu to operate optic test.

 

 

 

 

10

BROWNOUT_RST

YES

Brownout reset works in conjunction with

 

 

 

DSP_BROWNOUT. When DSP_BROWNOUT is

 

 

 

set, the CPU sends a signal to reset the display and

 

 

 

clear the DSP_BROWNOUT.
