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
. Set parameters H3-01, H3-05, and H3-09 accordingly as shown in
.
and Jumpers on the Terminal Board on page 104
for locating jumper S1.
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
. 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.
Refer to Switches and Jumpers on the Terminal Board on page
