 H4-02, H4-03: Multi-Function Analog Output Terminal FM Gain and Bias
H4-05, H4-06: Multi-Function Analog Output Terminal AM Gain and Bias
Parameter H4-02 and H4-05 set the terminal FM and AM output signal level when the value of the selected monitor is at
100%. Parameter H4-03 and H4-06 set the terminal FM and AM output signal level when the value of the selected
monitor is at 0%. Both are set as a percentage, where 100% equals 10 Vdc or 20 mA analog output and 0% equals 0 V or
4 mA. The output voltage of both terminals is limited to +/-10 Vdc.
The output signal range can be selected between 0 to +10 Vdc, -10
to +10 Vdc, or 4 to 20 mA using parameter H4-07 and
H4-08. Figure 5.86 illustrates how gain and bias settings work.
Using Gain and Bias to Adjust Output Signal Level
When viewing a gain setting parameter (H4-02 or H4-05) on the digital operator, the analog output will supply a voltage
signal equal to 100% of the monitor value (including changes made from bias and gain settings). When viewing a bias
setting parameter (H4-03 or H4-06), the analog output voltage will supply a signal equal to 0% monitor value.
Example 1: To have an output signal of 5 V at terminal FM when the monitored value is at 10
0%, set H4-02 to 50%.
Example 2: To have an output signal of 10 V at terminal FM when the monitored value is at 76.7%, set H4-02
to 150%.

Example 3: To have an output signal of 3 V at terminal FM when the monitored value is at 0%, set H4-03 to 30%.
