AD-8130 and AD-8230 series amplifiers include a
field-adjustable command signal monitor that can be
set for lock-in-place, or drive to a pre-set position if the
current command signal is lost. They also have a
dynamic brake circuit which helps increase positioning
accuracy of the loop by minimizing motor coast.
These amplifiers are also equipped with a 4-20mA
isolated two wire, loop-powered transmitter.
Anti-Condensation Heater
: 120 or 240 Vac, 30 Watt
with thermostat set for 110°F (43.3°C).
Local Auto/Manual INC/OFF/DEC Toggle Switches
Output Shaft
: 20 tooth splined shaft for use with
splined drive arm.
20 Tooth Splined Drive Arm
: Reversible for ½ tooth
positioning.
Adapter/Clevis Kit
: Includes two clevises, two adjust-
ment rods with lock nuts, two pipe adapters, two pins
for clevises.
Auxiliary Position Limit Switches
: (two or four): 20
amps, 250 Vac maximum.
Transmitter Position Feedback
: 4 to 20mA, isolated
two wire loop-powered type.
Local Position Indicator
: Reversible indicator.
Contactless LVDT Position Feedback
: - Linear,
square, square root and field contourable cams sup-
plied.
Potentiometer
: 1000 ohm, 2 watts, 36 Vdc max.
Installation
MOUNTING
The outline and mounting dimensions for a standard unit
are shown on the last page of this manual. The rear cover
opposite the output shaft must have clearance so it can
be removed for adjustments and interconnect wiring.
When the actuator is directly coupled to a drive shaft, a
Jordan Controls type coupling is recommended. The
output shaft is also available with a splined output for
standard drive arms and linkage components to the
driven load.
The unit may be mounted on the standard foot mount,
the face mount around the output shaft, or on two sets of
side holes for a bracket mount. Mounting may be in any
position convenient to the driven load. When mounting
the unit, be sure that no excessive axial or side loading is
applied to the output shaft.
The limit switches and position feedback are gear con-
nected to the actuator output shaft. Positively secure the
output shaft to the driven load shaft to prevent slippage,
which would cause misalignment or damage.
The manual handcrank is engaged for operation at all
times. When the manual override is required, the crank
should be turned in the appropriate direction for output
shaft movement. If during manual operation electric
power is applied to the actuator, this power cannot drive
back through the manual handcrank and harm the opera-
tor. Power must be removed or motor position overrides
manual position.
Torque of approximately seven inch pounds on the
handcrank will provide up to 2,400 inch pounds at the
output shaft. It takes approximately three full turns of the
handcrank to move the actuator output shaft one degree.
When the torque rating of the unit is reached, depending
upon the direction of cranking, the handcrank will move
in or out axially, an indication that full torque is being
delivered to the load.
The motor, limit switch, and feedback area of the actuator
depends upon the cover to maintain the NEMA Type 4
rating. This cover should be removed only when work is
being done internally, and should be reinstalled immedi-
ately upon completion.
This unit contains no internal mechanical stops. If it runs
outside of the initial factory alignment of the limit switches,
a realignment of switches and feedback may be required.
However, no internal damage will have occurred.
