The PHUCN600 Series multi-parameter controller is a
microprocessor-based controller capable of measuring
pH, ORP, or conductivity.

There are two displays on the PHUCN600 Series: a bright LED
numeric display with bar graph on the outside front panel, and a
2-line, 16-character LCD display on the inside. The LED readout
on the outside panel can be seen several yards away. The
distinctive, color-coded bar graph will immediately indicate if you
are within the process parameters that you set (green), if the
control relays are on (yellow), and if you are in alarm condition
(red). This makes diagnosing pump and alarm malfunctions easy.
All configuration and control functions are performed on the LCD
menu on the inside front panel.

A universal mounting kit is included for surface, panel, and pipe­mount applications. The ¹⁄₄ DIN enclosure makes panel-mount
cutouts and engineering simple.

Complete and versatile, the PHUTX600 is a ¹⁄₄ DIN two-wire
transmitter, which can measure conductivity, pH, or ORP. The
PHUTX600 comes complete with a universal mounting kit for
surface, panel, and pipe-mount applications. The NEMA 4X
(IP66) ¹⁄₄ DIN enclosure is perfect for stand-alone or panel-mount
operation.

PHUCN600 and PHUTX600 Series are packaged in a rugged
NEMA 4X (IP66) polycarbonate enclosure, making them ideally
suited for heavy-duty applications such as industrial wastewater
neutralization, municipal water and wastewater, pulp and paper,
and process control.

When the PHUCN600 Series is powered up for the first time,
it will display the meter selection screen where the meter type is
selected. This meter selection screen will only be displayed when
the PHUCN600 Series is powered up for the first time.

After the user selects a meter type, the PHUCN600 Series will
remain set to that meter type until it is changed with the meter
selection menu function in the Utilities menu.

To return the PHUCN600 Series to its factory settings, the user
re-selects the current meter type from the meter selection menu
function. This will override all setpoints and return all settings to
the factory settings.

The PHUCN600 Series User’s menu has been divided into five
main categories:
