Inlet Valve LEDs
The inlet valve modules are fitted with LEDs.
 Solid green LEDs indicate the flow is from the system pump.
 Solid blue LEDs indicate the flow is from the sample pump.
 Blinking green LEDs indicate the line to plumb using the Point-to-Plumb
feature.
 The Outlet LED is lit when the valve is in use.
 When one sample inlet valve is in line, a single LED indicates the active
inlet port.
 When two sample inlet valves are in line and sample flows from S2:
 Both Outlet LEDs are lit.
 The LED on the active port on S2 is lit.
 The 8/BB on S1 is lit.
