The analyzer/controller is housed in a rugged NEMA 4X (IP65) weatherproof, corrosion resistant enclosure of epoxy-painted aluminum. It is suitable for panel, pipe or wall mounting. All functions are accessible through the front panel membrane keyboard. The large back-lit dot-matrix liquid crystal display continuously indicates the measured variable in large numerals, along with the temperature, output value and two programmable process parameters (such as alarms or diagnostics variables). Three levels of security are available: 1) calibration, 2) output range and alarm setpoint adjustment, and 3) advanced configuration. A hinged front panel provides convenient wiring access. All operations and descriptive messages can be field selected for English, French, German, Italian or Spanish.

The two independent, isolated outputs provide 4-20 or 0-20 mA signals for the process measurement and temperature. The controller option also allows PID control choices acting on process measurement or temperature. Manual control of the output may also be selected for routine maintenance and tests.

Three process alarms are a standard feature. All alarms have programmable high or low activation, independent setpoints, adjustable hysteresis (deadband) and time delay. One relay may be configured as a timer relay for chemical cleaning, which may be activated at a specific time interval. An overfeed timer feature is also selectable for any one process relay. The control option allows each alarm the additional choice of Time Proportional Control. During any relay activation, a corresponding Green LED is illuminated.
