TEX-PRC

Process Controller

The TEX-PRC process controller interfac-

es smoothly with a wide range of PLC

and monitoring systems. Specically for

use in process applications, it accepts

0–20mA, 4–20mA, 0–2V or 0–10V

inputs.

This controller has been designed for

ease of use, with intuitive, scrolling text

prompts that guide you step-by-step

through the setup process. The front

panel includes 5 buttons, for simple

operator interface, and a 6-digit LED

display.

FRONT PANEL & DISPLAY

2.1 - Front panel

SPX

The SP LED's are used to

indicate active setpoints.

This button is used to

access the Input Setup & Calibration menu (Section 6).

This button is used to save your settings and advance to the next step in the setup process.

This button is typically used to scroll through options or increase values in the setup menu. Pressing this button from the main display allows you to view/reset the PEAK value (see 2.3).

This button is typically used to scroll through options or decrease values in the setup menu. Pressing this button from the main display allows you to view/reset the VALLEY value (see 2.3).

48mm

(1.89")

96mm (3.78")

This button is used to access the Setpoint Setup menu (Section 7) and the Setpoint Open Access menu (Section 8).

2.2 - Display brightness

To adjust the display brightness, press the and buttons together from the main display. BRI appears and toggles with the current setting. Use the and

buttons to adjust the LED backlight, and then press to nish.

2.3 - Up and down button shortcuts

Pressing the and buttons from the main operational display allows instant

access to peak and valley values held in the controller's memory, as shown below.

PEAK Maximum measured process input since the unit was turned on or reset

VALLEY Minimum measured process input since the unit was turned on or reset

PEAK or VALLEY may be reset to zero by pressing the and buttons at the same time while the variable is being displayed. These values may also be reset using

the function pins (see 3.6). Press at any time to return to normal operating mode.

3.2 - Wire the analog input See 3.1D

The analog input module has an input type header that is congured for 0/4–20mA input by default. This will need to be adjusted for voltage input applications.

Ideally you should do this before you continue wiring. Please see Section 5.

3.7 - Wire the power supply See 3.1F

DO NOT attempt to wire your controller while the power is on. NEVER connect your low voltage controller to mains power.

Wire your controller for low or high voltage power supply, as show in the diagrams

below. Check the label on the unit against the colour of the connector:

› Orange =

High voltage (85–265V AC,

95–370V DC)
