The End User Controller (EUC) allows manual control of the EPX pump and also displays the pump status. Refer to
Figure 7 which shows the front panel of the EUC display.
Use the run button ( Figure 7 , item 1) to start the EPX pump. The run button has an LED which is on when the EPX
pump is running. Use the stop button ( Figure 7 , item 10) to stop the pump.
The display ( Figure 7 , item 2) shows two lines of text; each line is 16 characters long. In normal operation, the Normal
display is shown; the Normal display has two pages, and each has two lines. Each page of the Normal display shows
the status of one or more EPX EUC sensors or internal clocks and counters. As supplied, the first page of Normal
display shows the pump serial number and pump current. It is possible to change the information shown on the Normal
display.

once the condition has been acknowledged.
