u Input Signal Selection for Terminals A1 and A2
Terminals A1 and A2 can be used to input either a voltage or a current signal. Select the signal type using jumper S1 as
explained in Table 3.12 . Set parameters H3-01 and H3-09 accordingly as shown in Table 3.13 . Refer to Switches and Jumpers
on the Control Board on page 84 for locating switch 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.

u Terminal FM/AM Signal Selection
The signal type for terminals FM and AM can be set to either voltage or current output using jumper S5 on the terminal board
as explained in Table 3.14 . 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 Control Board on page
84 for locating jumper S5.
