STATUS
System Ok ON if no faults are present.
Conc Valid ON if concentration measurement is valid, OFF when invalid.
High Range ON if unit is in high range of any AUTO range mode.
Zero Cal ON whenever the instrument is in ZERO calibration mode.
Span Cal ON whenever the instrument is in SPAN calibration mode.
Diag Mode ON whenever the instrument is in DIAGNOSTIC mode.
Unused
The emitters of the transistors on pins 1-8 are bussed together. For most
Emitter Bus applications, this pin should be connected to the circuit ground of the
receiving device.
Dc Power + 5 VDC source, 30 mA maximum (combined rating with Control Inputs)
Digital Ground The ground from the analyzer's internal, 5/±15 VDC power supply.
Control inputs allow the user to remotely initiate ZERO and SPAN calibration modes
provided through a 10-pin connector labeled CONTROL IN on the analyzer's rear
panel. These are opto-isolated, digital inputs that are activated when a 5 VDC signal
from the "U" pin is connected to the respective input pin.
