3.1 User Interface
The User Interface is shown below (Figure 20).
Figure 20 – User Interface
The User Interface consists of the following:
− Pump key (AUTO, FORCED ON, FORCED OFF)
− Alarm key (AUTO, FORCED ON, FORCED OFF)
− Power LED – GREEN (Power On = LED On)
− Alarm LED – RED (Alarm On = LED On)
− Pressure LED (Low Pressure = RED)
− Level LED (Low Level = RED)
The Pump key and Alarm key have an LED installed in the upper left corner of the key. The
color of the LED indicates the status of the Control Relay. Both the Pump and Alarm keys use
the same color coding.
− CLEAR – Auto-OFF
− GREEN – Auto-ON
− RED – Forced-OFF
− AMBER – Forced-ON
In this section the DGF1 controller/user interface was used as a reference. The DGF2
controller/user interface is similar in design, but has an additional pump key (PUMP 2) and
an additional pressure LED (PRESSURE 2).
