Connecting the Air Sensor Module
Instrument Guide | 103
5. To connect an air sensor to the system pumps:
a. Connect tubing from the buffer bottle or from the outlet port on the buffer
inlet valve to the port on top of an air sensor.
b. Connect tubing from the port on the bottom of the air sensor to the inlet
port on either system pump.
6. To connect air sensors to the buffer blending valve:
a. Connect tubing from each buffer bottle to the port on the top of each air
sensor that will be used.
b. Connect tubing from the port on the bottom of each air sensor to the inlet
ports on the buffer blending valve.
Alternatively you can attach tubing from outlets A and B of the buffer blending
valve to the top of the air sensors. Connect the ports from the bottom of each
air sensor to the inlets of system pumps A and B, respectively. In this setup,
although air will be prevented from entering the system pumps and the system
will react to end of buffer, the system will not distinguish which port to
replenish.
To activate the air sensors
1. Restart the NGC system.
The green LEDs on the air sensor module should turn on.
2. Select File > System Settings to open the System Settings dialog box.
3. Select the Air Sensors tab.
By default, only the air sensors that the system detects are enabled. The other
sensors are disabled.
4. For each air sensor that you want activate, select its checkbox and from its
dropdown list choose either Sample to detect end of sample or Buffer to detect
end of buffer.
5. Click OK.
