Define Instruments TEX-TOTAL Manuel utilisateur

The TEX-TOTAL rate meter and totalizer

is ideal for ow rate monitoring of trans-

mitters and sensors with mA output.

It features dual totalizers with low ow

cut-o and roll over, and input signal av-

eraging to stabilise measurement.

The TEX-TOTAL features a 6-digit alpha-

numeric LED display, with scrolling text

prompts that guide you step-by-step

through the setup process. The unit is

easy to scale to suit your desired time

and measurement units.

SPX The SP LED's are used to

indicate active setpoints.

This button is used to ac-

cess the Input Setup & Calibra-

tion menu (Section 5).

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 will allow you to view/reset

the Peak value, and view the Total 1 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 will allow you to view/reset

the Valley value, and view the Total 2 value (see 2.3).

This button is used to access the Totalizer Reset & Setpoint Setup menu (Sec-

tion 6) and the Setpoint Direct Access menu (Section 7).

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 a number of values held in the controller's memory. These variables will ap-

pear in the order shown in the table below, and will cycle continuously at each press

of the or button. Press at any time to return to normal operating mode.

PEAK and VALLEY may be reset to zero by pressing the and buttons at the

same time while the variable is being displayed.

Up and down button shortcuts

PEAK Maximum measured ow rate since the instrument was turned on/reset

TOTAL1 Current value of Total 1.

Total 1 will not appear in this list if it is set as your display source (5.5).

This value can be reset in 6.2B, or by the input pins (3.6).

VALLEY Minimum measured ow rate since the instrument was turned on/reset

TOTAL2 Current value of Total 2.

Total 2 will not appear in this list if it is set as your display source (5.5).

This value can be reset in 6.2C, or by the input pins (3.6).

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)

›Black =

Low voltage (15–48V AC,

10–72V DC)

4.2 - Installation instructions

A Prepare the Panel Cutout to

92 x 45mm ±.5 (3.62 x 1.77" ±.02),

as shown below. Allow at least

155mm (6.10") depth behind the

panel to accommodate the meter

body and protruding cabling.

B Remove the Mounting Clips from

the meter back.

C Slide the Panel Gasket over the

rear of the unit to the back of the

Meter Faceplate.

D From the front of the panel, insert

the meter into the Panel Cutout.

Holding the unit in place, engage

the Mounting Clips so that the tabs

snap into place over the notches on

the case.

E To achieve a proper seal, tighten

the Screws evenly until the unit sits

rmly against the panel. Do not

over-tighten the screws.

5 INPUT SETUP & CALIBRATION

5.1 - Enter F1 PIN number

A Enter the calibration mode by pressing the button.

_ _ ENTER F1 PIN NUMBER scrolls across the display and toggles with 0. Use the

and buttons to enter your security code (factory default 1). Then press

. If the correct PIN is entered, setup is started at 5.2.

If an incorrect PIN number is entered, _ _ INCORRECT PIN scrolls across the

display and it returns to normal operating mode.

You will have the opportunity to change your PIN number at the end of this section

(5.10). If you have forgotten your PIN number, see Section 8.

5.2 - Flow rate input setup

A _ _ FLOW RATE INPUT SETUP scrolls across the display and toggles with SKIP.

Press to skip to 5.3, or the button and then to ENTER input setup.

B _ _ MAINS FREQUENCY scrolls across the display and toggles with the current

selection. Use the and buttons to select 50HZ or 60HZ, and press .

C _ _ TIME UNITS FOR FLOW RATE scrolls across the display and toggles with the

current time units. Use the and buttons to select: /SEC, /MIN, or /HR,

and then press .

D _ _ RESOLUTION FOR FLOW RATE scrolls across the display and toggles with

the current ow resolution. Use the and buttons to select: 1, 0.1, 0.01, or
