3.1. 4-20mA Out Settings
Units with a 4-20mA output option will have a menu for setting up the 4-20mA output. The 4mA and 20mA
of 8.0.
SIGNAL SOURCE - Select which probe reading the
mA will use as its reading source.
4 mA VALUE - What the 4mA signal equals
20mA VALUE - What the 20mA signal equals on the
assigned signal sources scale.
CONDITIONER - Select a second reading that can
change or condition the original mA output.
3.2 4-20mA Input Settings
SET POINT - What reading turns the relay on
DIFFERENTIAL - Amount reading changes by before
HIGH ALARM - What reading generates a High alarm
LOW ALARM - What reading generates a Low alarm
DISABLER - Selected input will disable HIGH/LOW
3.3 4-20mA Output Calibration
4-20mA outputs can be calibrated to ensure that the
output generated by the controller and received by the
external device match. With a voltmeter connected
across the out and return wires (see page 7) of the
4-20mA output channel, to be calibrated, go into the
The number displayed in the Calibration dialog box
can range from 0-4,095, with 800 equal to 0 mA
output, and 4,030 equal to 20 mA. This number range
of 0-4,095 is the raw digital-to-analog (D/A) values and
is strictly used for reference. The D/A numbers that
you get will vary based on your installation conditions.
