DFI Infinity-Using This Quick Start Manual

Use this Quick Start Manual to get your High Performance Strain Gage Indicator up and running right out of the box. These instructions use the factory default settings of 100mV unipolar input and 10 Vdc sensor excitation. If you have voltage or current input, refer to the main manual. To start your unit:

¥ Connect ac power

¥ Wire the sensor

¥ Configure the meter, using the front panel buttons and the

configuration menus

Before You Begin

Your unit should have the following parts:

¥ Meter

¥ Front panel button cover

¥ Panel mounting gaskets

¥ ac Power Connector (orange -P1), Input Connectors (2)

(P3 and P9), and rear protective cover (mounted).

Contact the Customer Service Department using the number listed on the front of this manual if any of these parts are missing, or if you have questions.

In addition to the unit and related parts, you will need the following items to set up your unit:

¥ ac power as listed on meterÕs product/ID label

¥ External sensor (e.g.; load cell)

¥ 1/8Ó Phillips head screwdriver

¥ 1/8Ó flat blade screwdriver

Determine Meter Scaling Factor

Calculate the scaling factor so the meter displays the desired engineering units. Assuming no known load, use the formula:

RDG SC = display span/[(sensorÕs mV/V output) (10,000)]

where: display span = desired display at full scale

sensorÕs output span = mV/V

Configure the Meter

Use the front panel buttons to access the configuration menus, to either verify or set the unit values. The first table that follows describes functions of each button on the front of the meter. The second table summarizes the key sequences you must press and the menus you will see to get your meter running. For a step-by-step procedure of specific tasks, refer to the configuration sections following the tables.

Meter Button Descriptions

Press This Button To:

Access the configuration program menus and move from one menu to the next.

Enter and scroll through a submenu.

Change the value of a submenu.

Move backward one menu (press once), or exit the configurations menus (press twice).

Change the Setpoints.

Connect ac Power

1. Remove the rear protective cover and set it aside. The

cover is secured with a Phillips-head screw.

2. Locate connector P1 on the bottom-left-rear of the unit. The connector has three screw-down terminals (see below).

3. Insert the correct wire in each terminal and tighten the lockdown screw. Tug gently on each wire to verify the connection.

Wiring a Millivolt Output Sensor

The following example shows wiring a bridge input to the meter.

1. Locate connectors P3 and P9 on the right-side rear of the unit.

2. Attach the wires and tighten the retaining screws. Tug gently on the wires to verify the connection.

Wiring Example (Factory set at 10Vdc Excitation

3. Apply ac power. The front panel of the unit flashes

. If it does not: a. Remove ac power. b. Verify the P1 power and sensor connections. c. Check your power source. d. Apply ac power again.

4. Replace the rear cover. Thread the sensor wires through the slots on the side of the cover. Replace the rear cover retaining screw.

To Configure Scaling Factor:

1. Press 䊳/MIN to display and to select the digit (or decimal point) you want to change.

2. Press 䊱/MAX to increase the value of the selected digit.

3. Repeat steps 1 and 2 until each digit is the desired value (your calculated scaling factor).

4. Press MENU. The meter displays:

Configure Reading Offset

Now that you are in the run mode with a transducer connected to the meter, do the following:

1. Simulate a load on the transducer (leave the pressure port open).

2. Note the display reading. LetÕs assume the display shows 43.5.

3. To make the display show zeroes, press MENU until the meter displays:

4. Press 䊳/MIN to display the previous reading offset value.

5. Using 䊳/MIN to scroll through the digits and 䊱/MAX to change the value, enter the value -0043.5.

6. Press MENU. The meter displays:

7. Press RESET twice. The meter flashes and then displays a value.

Your meter is now in RUN mode and operational.

If You Have Bipolar Input ±50mV

The typical setting for your meter is unipolar. If, however, you have bipolar input ±50mV, you must install jumper S1B. Remove the outer panel mounting sleeve to expose the jumper.

S1 Jumper Location on Signal Input Board

In addition, you must set configuration menu value INP.3=1 (under IN CNF menu). Refer to the Configuration sections of this Quick Start manual.
