The PRIMEX PC-3000X controller is designed to operate up to three pumps in pump-up or pump-down applications. Intuitive menu navigation and quick setting adjustments are provided by a rotary selector wheel, back and escape buttons. The blue OLED display offers easy-to-read level readout and fault annunciation. When controlling the level in a tank, the input is connected to a 4-20mA sensor. It is configurable with no programming software required. A red LED indicates an active alarm, while green LEDs indicate the pumps required. It has multiple alternation configurations, bar graph levels and constant or variable speed control. 844/477-4639; www.primexcontrols.com; Booth 4339.
