Teledyne API Model 300M CO Analyzer Instruction Manual, 04033, Rev. A

5.2.1 Signal I/O

The signal I/O diagnostic mode gives the user access to the digital and analog inputs and outputs on the V/F board. The digital outputs can be controlled through the keyboard. Any signals manually changed through the signal I/O menu will remain in effect until you leave the signal I/O menu. At that time the analyzer will regain control of these signals. To enter the signal I/O test mode, press SETUP-MORE-DIAG-ENTR. When the diagnostic mode is entered, a message is sent to the RS-232 channel indicating entry into the diagnostic mode. Use the PREV and NEXT buttons to scroll through the signals. Edit buttons will appear for the signals that can be controlled by the user. Press JUMP to skip to a specific I/O Signal.

Table 5-2lists the I/O signals available for the M300M.

Table 5-2: I/O Signals

#	Signal	Control	Description
0	DISP_BROWNOUT	NO	Display brownout is used to keep the display from
			getting corrupted during low line voltage conditions.
			Circuitry on the Power Supply board (00015) senses
			low line voltage and sets this bit. The CPU reads this
			and generates the BROWNOUT_RESET signal
			described below.

1	EXT_ZERO_CAL	NO	Shows state of status input bit to cause the M300M 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 M300M to
			enter the Span Calibration mode. Use to check
			external contact closure circuitry.

3	SYNC_OK	NO	Indicates that demodulation circuitry on the
			Sync/Demod Board (00798) is able to lock-in on the
			detector signal.

4	ZERO_SCRUB_VAL	YES	Switches the Autozero scrubber valve. Use this bit to
	VE		test the valve function.

5	CAL_VALVE	YES	Switches the Sample/Cal valve. Use this bit to test the
			valve function.

6	SPAN_VALVE	YES	Switches the ZERO/SPAN valve. Use this bit to test
			the valve function.

7	BENCH_HTR	YES	Shows the status of the optical bench heater. This has
			the same function as the LED in the power supply
			module.
