6.8.2. Control Inputs

Control inputs allow the user to remotely initiate ZERO and SPAN calibration modes are
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.

Status
ON if no faults are present.
ON if concentration measurement is valid, OFF when invalid.
ON if unit is in high range of any AUTO range mode.
ON whenever the instrument is in ZERO calibration mode.
ON whenever the instrument is in SPAN calibration mode.
ON whenever the instrument is in DIAGNOSTIC mode.
ON if unit is in low range of any AUTO range mode.
Unused.
The emitters of the transistors on pins 1-8 are bussed
together. For most applications, this pin should be connected
to the circuit ground of the receiving device.
