Specifications
Standard Line Voltage
: 120/240Vac, ±10%,
50/60 Hz (Slide switch select)
(Voltage input MUST match
the actuator motor voltage
rating).
Power Consumption
: Less than 20 watts for amplifier
functions only.
Voltage Output:
Identical to voltage input.
Current Output:
10 amps max. at 120 or 240 Vac.
Fuse protection:
Customer supplied. Size based on
actuator controlled and local codes.
Null output (AD-8240):
Rated 2 ampers
@120/240Vac, 50/60Hz.
Command Signal Inputs
:
• 4-20mA, 4-12mA, 12-20mA into a 200
Ω
shunt
resistor
• 0-5Vdc into 100,000
Ω
impedance
• 0-10Vdc into 100,000
Ω
impedance
Position Feedback Signal
: 1000
Ω
potentiometer
4-20mA (optional on
AD-8240 models only).
Position Output Signal
: Isolated 4-20mA, loop
powered with 12-36Vdc
external power supply.
Field Wiring Terminations
: Plugable terminal block,
wire size range 26-14
AWG.
Command Signal Monitor
: The 8000 series loss-of-
signal circuitry monitors
the command signal
input. If the command
signal drops below or
above the rating, the
actuator will either lock
in place or run to a
preset position (user
selectable).
Limit Signals
: Internal: Part of servo control.
Output Shaft Motion
: All models can go either
direction on an increasing
command signal. This is
determined by the ZERO and
SPAN settings.
Temperature Limits
: -40° to 150° F (-40° to 65° C).
Duty Cycle
: Unrestricted modulating duty.
(Cont. duty).
Position Accuracy
: 1% of full range.
Deadband
: Factory preset to 1%. Field adjustable.
Troubleshooting
For visual troubleshooting, LEDs are provided to display the status of the actuator.
These are located on the same side of the lower board as SW1. The identification of
these LEDs are shown in the table below.
LED
Function
MICRO OK
This LED flashes when the microprocessor is running. If this is not on, verify
power to the board.
INC
This LED is on when the actuator is extending the ouput shaft for linear
actuators, or rotating the output shaft CW for rotary actuators.
DEC
This LED is on when the actuator is retracting the ouput shaft for linear
actuators, or rotating the output shaft CCW for rotary actuators
1 Flash - Indicates loss of 4-20 mA signal (LOS).
2 Flashes - Indicates loss of the feedback signal.
3 Flashes - Indicates a stall condition.
