Pump Modes Single Pump Mode In Single Pump mode, the screen displays as shown below. The upper left corner displays the active station being loaded. If the system has no active station, two (2) hyphens -- in the station area display. The lower left corner displays the load time in seconds. When a station is loading, this area displays how much time elapses during the load cycle. If no station is active, three (3) hyphens --- display. The upper right area displays the status of the control.
Station Icons Below the text portion of the screen, 12 station icons display the status of each station in the system. Each station icon contains four segments. Figure 3: Station Icon Segments Label Segment 1 Description 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.
Status Indicators Four (4) status indicators are located below the station icons at the bottom of the display. These indicators include PUMP, BLOWBACK, HIGH VACUUM, and SYSTEM. Each icon word has a 1 and a 2 icon with it, indicating Pump 1 or Pump 2. Figure 4: Status Indicator Icons Icon PUMP BLOWBACK 1 2 1 HIGH VACUUM CHECK SYSTEM 2 1 2 1 2 2–Pump 12-Station Controllers Label Pump Status Indicator Description The PUMP status indicator specifies an active pump.
Controller Keypad Your 12-station controller has a 16-position keypad to let you operate and alter controller parameters. With the exception of the SET key, each key has at least two functions. The status of the controller determines what function is recognized.
4-3 Operation Your 12 station controller electrically controls valves and solenoids to convey material from a central location to individual stations as needed. The controller works within this process by sensing a material demand and responds in a timely fashion to that demand. An active signal sent from a demand sensor prompts the controller to place the station in a demand queue. The controller responds to this condition by loading the stations in a first come, first served basis.
Label LOADING Description Following the IDLE (Startup) state, the vent valve is closed and the first station in demand loads when that station sequence valve opens. This is the LOADING state. You can define load times for each station. The controller loads the station in demand until one of the two events below occur: 1. The volume fill sensor becomes active. 2. The load time is exhausted.
