DECS-150 startup functions consist of soft start settings as shown in Figure 21-4.
Soft Start
During startup, the soft start function prevents voltage overshoot by controlling the rate of machine
terminal voltage buildup (toward the setpoint). Soft start is active in AVR and FCR regulation modes. Soft
start behavior is based on two parameters: level and time. The soft start level is expressed as a
percentage of the nominal machine terminal voltage and determines the starting point for machine
voltage buildup during startup. The Soft Start Time setting defines the amount of time allowed for the
buildup of machine voltage during startup. Two groups of soft start settings (primary and secondary)
provide for independent startup behavior which is selectable through BESTlogic™Plus.
The PWM Startup Duty Cycle setting gives the user the ability to adjust the initial startup pulse width of
the DECS-150’s output to the field of the machine during the soft start sequence.
