4.4.10 Setting the 4mA point

Screen Display:

4

 

Factory default value:

0.000

Enter the value of the PV which you require to be signalled by 4mA

The 4mA point may be set above or below the 20mA point to suit the monitoring or control equipment. If you wish to set the 4 and 20mA points by ranging the MSP400 to a fixed target, such as the level in the vessel at any particular time or a fixed target at a known distance away, skip these menu options now by pressing the green button D 2 times to arrive at the set damping option.

To edit the 4mA point

a)Press the blue button to enter the 4mA menu and to display the current value in use. If this is correct, press the red button return to the main menu.

If the 4mA point is to be edited, press the blue button again to allow editing

The leading digit of the current 4mA value will now be flashing, indicating it may be changed.

b)Use the green button D to edit the value of the leading digit.

c)Once correct, use the blue button to select the next digit and then the green button D to edit as before, or the blue button to move to the next digit. Continue this sequence until all 5 digits are correct.

If the new 4mA value is incorrect, the edit sequence for the 4mA point can be re-started by pressing the blue button again.

If the 4mA value is correct, press the red button to save the new value to memory and automatically scroll on to the next main menu option: “20”
