Code Description
AO2
Bias 0.0%
20.0%
(factory
Default)
OUT-10 AO2 Filter Sets the filter time constant of the analog output.
OUT-11 AO2
Const % Sets the analog output items to Constant (AO2 Mode: 15), and then the analog
current is output at the value of the parameters set.
OUT-12 AO2
Monitor Monitors the analog output value, which is represented as a percentage based
on the 20 mA maximum output voltage.
Note
When 4 – 20 mA is used as the output, tune OUT-08 AO2 Gain and OUT-09 AO2 Bias as follows.
1 Set OUT-07 AO2 Mode to Constant and OUT11 AO2 Const % to 0.0%.
2 After setting OUT-09 AO2 Bias to 20.0%, ensure that that the current is 4 mA. If the current is
lower than 4 mA, gradually increase OUT-09 AO2 Bias until it measures 4 mA. If the current is
higher than 4 mA, gradually decrease OUT-09 AO2 Bias until it measures 4 mA.
3 Set OUT11 AO2 Const % to 100.0%. After setting OUT-08 AO2 Gain to 80.0%, ensure that the
current is 20 mA. If the current is lower than 20 mA, gradually increase OUT-08 AO2 Gain until it
measures 20 mA. If the current is higher than 20 mA, gradually decrease OUT-08 AO2 Gain until
it measures 20 mA.
4 When 0-20 mA is used as the output, set OUT-08 A02 Gain to 100% and OUT-09 A02 Bias to
0.0%.
5
The functions for each code are the same as the item of 0 – 10 V output. And, the output range is
0 – 20 mA.
