Code Description
OU.04 AO1 Filter Set filter time constant on analog output.
OU.05 A01
Const %
Used for calibration of the analog output. If analog output at OU.01 (AO1 Mode)
is set to 15(Constant), the analog voltage output is dependent on the
percentage set in OU.02 (Gain) and OU.03 (Bias) values (0
–
100%). See 4-20mA
scaling example below.
OU.06 AO1
Monitor Monitors analog output value. Displays the maximum output voltage as a
percentage (%) with 10V as the standard.
Example: 4-20mA scaling
OU.02 AO1 Gain and OU.03 AO1 Bias Tuning Method for 4
––––
20mA output.
1 Set OU.01 (AO1 Mode) to constant, and set OU.05 (AO1 Const %) to 0.0 %.
2 Set OU.03 (AO1 Bias) to 20.0% and then check current output. 4mA output should be displayed.
3 If the value is less than 4mA, gradually increase OU.03 (AO1 Bias) until 4mA is measured. If the
value is more than 4mA, gradually decrease OU.03 (AO1 Bias) until 4mA is measured.
4 Set OU.05 AO1 Const % to 100.0%
Set OU.02 (AO1 Gain) to 80.0% and measure current output at 20mA. If the value is less than 20mA,
gradually increase OU.02 (AO1 Gain) until 20mA is measured. If the value is more than 20mA,
gradually decrease OU.02 (AO1 Gain) until 20mA is measured.
The scaling for the other functions is identical to the example for the 4-20mA output range.
