Setting the Output Damping

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 will flash 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 4 mA level. 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 “4” re-appears; re-start at step (b) or press ↓ for the next menu.

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 20 mA value:

a)If entering the menu system from the PV display, press the green button ↓ repeatedly until the “20” menu option is indicated (see above note.)

b)Press the blue button → to enter the menu for the 20 mA level. The display indicates the present value of the 20 mA level.

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 20 mA level. 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 “20” re-appears; re-start at step (b) or press ↓ for the next menu.

The damping value is a time constant in seconds, and is applied as smoothing to the level reading and the output current. A new value may be entered up to 999 seconds. A larger value will have the effect of smoothing out rapid changes of level, and smooth out the effects of turbulence and ripples on the liquid surface. (It would be unusual to select a value greater than 30 seconds).

A value of zero may be edited, in which case no smoothing is applied to the Current Output and transmitter readings immediately change the output.
