MATCHING COLUMN FLOWS
When you are matching column flows, refer to the Data Package for flow rates and valve
configurations. Although methods of matching column flows vary with valve configurations, the
following procedures apply to most configurations. Verify flows using a flow meter connected to the
point being checked (e.g., cell vent).
Manual Operation of Valves
Operate the valves manually as follows:
1. On the Background screen press the F2 (Manual Control) soft key.
2. On the Manual Control Mode screen (see Figure 2-5), the first line (“Valves:”) indicates which
valves are ON. The cursor will be on the second line (“Enter Valve: 0”), which enables you to
turn valves on and off.
3. To turn Valve One ON, verify that the number “1” does not appear on the first line, then press the
“1” key on the keyboard. The number “1” appears momentarily on the second line and then
appears on the first line.
4. To turn Valve One OFF, verify that the number “1” appears on the first line (“Valves:”). Move the
cursor to the second line and press the number “1” key. The number “1” disappears from the first
line of the screen.
5. Turn Valve Two and other valves on and off manually in the same manner.
