Basler AVC63-4 Instructions For Use Manual

INTRODUCTION
AVC63-4 and AVC63-4D analog voltage controllers regulate
voltage on 50 or 60 hertz brushless generators. The
controllers include frequency compensation, over-excitation
shutdown, solid-state buildup circuitry, and EMI filtering.
AVC63-4 adjustment potentiometers are located on the
terminals and components side of the controller (see Figure
1). AVC63-4D adjustment potentiometers are accessed
through the controller front panel (see Figure 2).

CONTROLS
AVC63-4 and AVC63-4D controls consist of jumpers and
screwdriver-adjusted potentiometers.
Jumpers
Two jumpers connect to the controller terminals: the Corner
Frequency jumper and the Voltage Adjust Rheostat jumper.
These jumpers are shown in Figure 3.
Corner Frequency Jumper
Analog voltage controllers are delivered with the Corner
Frequency Jumper set for 60 hertz operation. This gives a
corner frequency of 55 hertz. For 50 hertz operation and a
corner frequency of 45 hertz, the Corner Frequency jumper
must be moved to the 50 Hz terminal.
Voltage Adjust Rheostat Jumper
Analog voltage controllers are delivered with the Voltage
Adjust Rheostat jumper connected across terminals 6 and 7.
This enables adjustment of the generator output voltage
through the controller's internal Voltage Control potenti-
ometer. Clockwise rotation of the voltage control increases
generator voltage.
If remote adjustment of the generator output is desired, the
Voltage Adjust Rheostat jumper must be replaced with a
user-supplied rheostat. A 1000 ohm, ½-watt rheostat will
provide adequate voltage adjustment range for most
applications. Figure 8 shows the proper remote rheostat
connections.
Potentiometer Controls
AVC63-4 potentiometer controls are located on the
components and terminals side of the controller and are
shown in Figure 1. AVC63-4D potentiometer controls are
accessible through the controller front panel and are shown
in Figure 2.
INPUT POWER/SENSING INPUT
Power for the exciter field and analog voltage controller is
derived from the generator output. The acceptable power
input range is 171 to 264 Vac and is connected to terminals
3 and 4. Connect wiring as shown in the interconnection
diagram of Figure 8.
EXCITER FIELD POWER CIRCUIT
Controller terminal F+ is connected to the brushless exciter
field positive terminal and controller terminal F– is
connected to the brushless exciter field negative terminal.
The exciter field dc resistance must be 15 Ω or
greater and less than 100 Ω.
If the exciter field dc resistance is less than 15 Ω and the
full-load field current does not exceed the maximum
continuous current rating of the controller, a resistor of
