Analog current output (4-20mA)
SPEC
Please see the page of monitoring screen.
Cable wiring
Please see the page of mechanical and electrical installation.
Parameter setup
Please refer to the parameter set-up page.
Set-up steps as below:
Please set up the basic parameters first.
Connect cable first according to the cable wiring instructions on this page.
Set up parameter E06 for opening Analog current output function, and select the data content to be output.
The current range to be set up by using parameter E13 is 4-20mA.
Parameter E07 and E08 are for specifying maximum and minimum value to output. These 2 values can be either positive or negative, however, E07 has to be smaller than E08.
Use E09 to set output current milliamps when output data is out of the E07 and E08 range.
Please enter the E11 parameter page to test and adjust 0mA/ 4mA output current. Adjustment unit is uA.
Please enter the E12 parameter page to test and adjust 20mA output current. Adjustment unit is uA..
If the output current is too low and can not reach 20mA after modifying parameter E12, please check the 4-20mA specification on the monitoring screen page for line impedance and supply voltage requirement.
Use parameter F01 for setting up the flow volume value to be simulated. Turn on F02 and go back to the monitoring screen.
Confirm that the external device receives the signal correctly.
Turn off F02 and go back to the monitoring screen.
Finish.
