Sample System Status Panel
The sample system status panel illustrates the sample system and valve modes.
The status panel is shown in Figure 4-2. The panel is marked with a scaled
version of the flow schematic.
At the appropriate points in the flow schematic, the valve lights indicate the
status of each of the pneumatic valves PV1 to PV10.
• A green light indicates that the valve is OPEN.
• A red light indicates that the valve is CLOSED.
Metering valve MV1 is located in the Ultra Trace Oxygen sensor compartment
and controls the flow rate of electrolyte sparging. Turn the knob clockwise to
close the valve completely. The valve should always be closed when not in use.
See Figure 4-3.
CAUTION: Close any valves gently. If valves are over-tightened, the
valve stems can be damaged.
Metering valve MV2 is located near the rear of the sampling system and
controls the sample bypass flow rate.
Metering valve MV3 is located near the middle of the right side of the water
reservoir and below the analyzer top cover plate and controls the water drip rate
to the Ultra Trace sensor. See Figure 3-11.
On some units, a toggle switch has been installed to switch solenoid valve 9 (see
Figure 4-2) off and on. This switch is shown in the inset of Figure 3-6. It is used
to dislodge any trapped gas in the water replenishing line. Units without the
switch have an additional menu in the software labelled RESVR which
automatically toggles the solenoid valve.
