No. Name Setting Range Default
H4-05 Multi-Function Analog Output Terminal AM Gain -999.9 to 999.9% 50.0%
H4-06 Multi-Function Analog Output Terminal AM Bias -999.9 to 999.9% 0.0%
Using Gain and Bias to Adjust Output Signal Level
When viewing a gain setting parameter (H4-02 or H4-05) on the HOA keypad, 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: Set H4-02 to 50% for an output signal of 5 V at terminal FM when the monitored value is at 100%.
Example 2: Set H4-02 to 150% for an output signal of 10 V at terminal FM when the monitored value is at 76.7%.
