Setting the Bottom Reference

Screen display:

b.rEF

Defaults:

8.000 (m), 26.24 (ft.), 314.9 (in.)

NOTE:

See Figure 4-1 on page 4-3 for a map of the programming menu structure and how to access all the menu options.

To change the bottom reference (b.rEF) setting:

a)If entering the menu system from the PV display, press the green button ↓ to indicate the “b.rEF” menu option (see above note.)

b)Press the blue button → to enter the menu for b.rEF. The display indicates the present b.rEF value.

c)If this value is correct, press the red button ↵, and then press the green button ↓ to get to the next menu option.

d)Press the blue button → to start editing. The first digit flashes to indicate it can be edited.

e)Press the green button ↓ repeatedly to edit the flashing digit.

f)Press the blue button → to move to the next digit. The digit flashes to indicate it can be edited.

g)Repeat steps (e) and (f) until the last digit is flashing, and edited as required.

h)Press the blue button → to confirm the new b.rEF value. None of the digits should now be flashing.

i)If the new value is correct, press the red button ↵ to save. The display changes to the next menu option.

j)If the new value is incorrect, press the blue button → to exit to the menu. The “b.rEF” re-appears; re-start at step (b) or press ↓ for the next menu.

Setting 4 mA and 20 mA Levels

Screen display:

4 and 20

4mA level defaults:

0.000 (m), 00.00 (ft.), 000.0 (in.)

20mA level defaults:

7.500 (m), 24.60 (ft.), 295.2 (in.)

The 4 mA level may be set above, or below, the 20 mA level to suit the monitoring or control equipment.

NOTE:

To set the 4 and 20 mA levels by ranging the transmitter to a fixed target, such as the level in the tank at any particular time, skip these menu options by pressing the green button ↓ twice to get to the next menu option.

NOTE:

See Figure 4-1 on page 4-3 for a map of the programming menu structure and how to access all the menu options.

To change the 4 mA value:

a)If entering the menu system from the PV display, press the green button ↓ repeatedly until the “4” menu option is indicated (see above note.)

b)Press the blue button → to enter the menu for the 4 mA level. The display indicates the present value of the 4 mA level.
