Figure 3: Station Icon Segments

Label	Description
Segment 1	The top segment indicates the status of the valve above each station. When
	the valve is open (control output energized), this icon highlights. In Single
	Pump mode, only one valve indicator is active at a time. In Dual Pump
	mode, up to two valve indicators can be active at a time. When this
	indicator flashes, it indicates the assignment of a priority convey.
Segment 2	The center square segment indicates the existence of a station specific alarm
	condition. The alarm is typically related to a No Convey condition, but can
	also indicate the station with a high vacuum condition.
Segment 3	Located on the bottom of the station icon, the lower segment indicates the
	station demand input. This is a real time indicator, displaying when the
	station demand input is active. This indicator may toggle on and off during
	the load cycle, and should be considered normal.
Segment 4	Segment 4 is the indicator word ON, located below the station icon. When
	ON displays, the related station loads when the system senses a demand
	signal. When ON does not display, the station demand input signal is
	ignored and the related station does not load. Segment 4 blinks with
	Segment 2 in a high vacuum condition.
