10.1.3.1 Signal I/O Diagnostic
Table 10-4: Diagnostic Mode - Signal I/O
No. Signal Control Description
0. 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
(01086) 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
M100AH 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
M100AH to enter the Span Calibration mode. Use
to check external contact closure circuitry.
3. EXT_LOW_SPAN YES Shows state of status input bit to cause the
M100AH to enter the Low Span Calibration mode.
Use to check external contact closure circuitry.
4. ZERO_VALVE YES Switches the Zero valve. Use this bit to test the
Zero valve function.
5. CAL_VALVE YES Switches the Sample valve. Use this bit to test the
valve function.
6. HIGH
_SAPN_VALVE
YES Energizes the high span valve. Use this bit to test
the valve function.
7. RCELL_ HEATER NO Shows the status of the reaction cell heater. This has
the same function as the LED in the power supply
module.
8. ELEC_TEST YES Turns on electric test bit in Preamp. Should be used
for troubleshooting Preamp circuit. 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 isolating PMT detector system from the rest of
the Preamp circuit. We recommend you use the
OPTIC TEST button in the DIAG menu to operate
optic test.
