TEX-FLO10

Flow Rate Dual Totalizer

This sophisticated panel mount control-

ler is the ideal solution for a variety of

ow rate applications.

It features a customizable display, dual

totalizers with low ow cuto, volumet-

ric pulse on setpoints, and batching on

Total 1.

It's also designed for ease of use, with in-

tuitive, scrolling text prompts that guide

you step-by-step through the setup pro-

cess, and simple K-factor entry.

This button is used to save

your settings and advance to the next step in the setup process. It can also be

congured to reset the batch value to zero aer a long press (> 2secs) from

the main display (see 6.4E to enable).

This button is typically used to scroll through options or increase values in the

setup menu. Pressing this button from the main display will show the current values for FLOW and TOTAL1, (excluding either value if it is set as the display

source in 6.6B). 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 show the current

value for TOTAL2, (unless the display source is set to TOTAL2 in 6.6B). See 2.3.

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

tion 7) and the Setpoint Direct 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 backlight, and then press to return to operating mode.

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.

Up and down button shortcuts

FLOW Current ow rate value

TOTAL1 Current value of Totalizer 1

TOTAL2 Current value of Totalizer 2

If any of these values are set as your display source in 6.6B, they will be excluded from this quick-display menu. TOTAL1 and TOTAL2 can be reset using an external switch connected to the function pins (see 3.1D).

Press

at any time to return to the main display.

IMPORTANT: The input module for this unit has four headers which are factory congured to suit your application. The unit is congured for an NPN type sensor by default.

¨ If you are using an NPN type sensor, you don't need to change anything.

¨ If you are using PNP, TTL, Namur, Tacho, or a Pushbutton switch, please

review your header configuration before continuing, referring to Section 5.

Then wire your input as required, referring to the diagrams on the following page.

If your controller has relay outputs tted, wire them as per the appropriate diagram

below, depending on how many relay outputs you have installed. Relays can be pro-

grammed to operate within the total span range of the controller.

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)
