Terminals A1, A2, and A3 Input Signal Selection
Terminals A1, A2, and A3 can be used to input either a voltage or a current signal. Select the signal type using jumper S1 as
explained in Table i.13. Set parameters H3-01, H3-05, and H3-09 accordingly as shown in
Note: If terminals A1 and A2 are both set for frequency bias (H3-02 = 0 and H3-10 = 0), both input values will be combined to create the frequency
reference.

Terminal AM/FM Signal Selection
The signal type for terminals AM and FM can be set to either voltage or current output using jumper S5 on the terminal board
as explained in Table i.15. When changing the setting of jumper S5, parameters H4-07 and H4-08 must be set accordingly.
The default selection is voltage output for both terminals.
