1. Actuator Connection Terminals
The actuator connections, which were previously on terminals 5(–) & 6(+) (on 8272-689), have been relocated to terminals 9(+) & 10(–) on the 9907-014.
2. Accel Rate Capacitor Function
The optional external Accel Rate Capacitor (used in 8272-689) is no longer required for the 9907-014.This function is now integrated internally and can be adjusted via the Ramp Time potentiometer on the 9907-014 control.

The 9907-014 adds dedicated terminals for optional inputs, enhancing functionality:
SPM Synchronizer input: Can be connected to terminals 15 and 16.
Auxiliary input: Can be connected to terminals 15(+) and 17(–).
4. External Droop Potentiometer Terminals
For the optional external Droop potentiometer (compared to 8272-689):
The slider connection is moved from terminal 14 to terminal 13.
The clockwise lead connection is moved from terminal 13 to terminal 14.
5. Rated/Idle Speed Contact Terminals
The contact for "Close for Rated speed and Open for Idle speed" is relocated:
Previously on terminals 9 & 10 (on 8272-689), it is now on terminals 2 and 5 of the 9907-014.
