GENERAL ACTUATOR DESCRIPTION
The AD-8000 series of digital servo amplifiers are
on/off triac output AC servo amplifiers suitable for
operating a variety of Rotork Controls actuators.
Standard features include: onboard switch selectable
command input for 0-5Vdc, 0-10Vdc, or 4-20mA;
selectable loss of command signal operation; 4-20mA
isolated output transmitter tracking actuator shaft
position; dynamic motor braking; 120 to 240Vac, 50/
60Hz input power depending on actuator motor being
used; and on-board LED’s and encoder adjusting knob
for ease of set-up.
The customer’s command signal is isolated from both
the ac line and the electric motor in the actuator. In
addition, the AD-8240 servo amplifiers feature an
isolated, “null” output for customer use.

General Information
Most installations locate the servo amplifier inside a
Rotork Controls actuator, for ease of mounting and to
protect the amplifier. This is the preferred mounting
arrangement. For remote mounting, the servo
amplifier and actuator should be as close to each other
as possible.
Ensure all connections are correct and tight before
applying power. Power, command signal, feedback
signal, and motor output are the minimum required
connections.
To connect optional features refer to wiring diagram
for the specific amplifier and actuator.
Installation Wiring
All wiring should be done in accordance with
prevailing codes by qualified personnel.
Typical wiring diagrams are shown on page 7. Actual
wiring should follow the print supplied with the
actuator.
Fusing must be installed in line with input power, and
should be of the slow blow type. After installation, it is
recommended that all conduits be sealed to prevent
water damage. All low level signal wiring should be a
shielded type with the shield grounded at source
common.
