The Indelac AMC-100/AMC-101 AC Motor Controllers
are used for proportional positioning of split phase AC
actuator motors. An external command signal of 0-10V,
1-5V, or 4-20mA can be used to compare to a feedback
signal from a potentiometer. The open or closed AC
output will energize, which powers the actuator motor,
until the feedback signal matches the command signal, at
which time the controller's AC output is turned off and the
actuator motor stops. With a loss of command signal in
the 1-5V or the 4-20mA input range, the AMC-100/
AMC-101 offers three useful options: fail in place, the
open output on, or the closed output on. All input and
output options are easily field configurable with jumper
plugs. The only other ad-justments consist of Deadband
and non-interactive Zero and Span trimmers, which
allows for easy field calibra-tion. These controllers are
available in versions for 117VAC ±10%, 234VAC ±10%,
or 24VAC ±10% power and give the user optical isolation
between the input signal and the AC outputs. The unit
includes a red LED indica-tor (for the open output), a
green LED indicator (for the closed output), an on-board
fuse, and two removable screw terminal strips (for easy
servicing). The AMC-100 (117VAC), AMC-100B (234
VAC), and AMC-100D(24VAC) are mounted on Snap-
track and deliver 2A at 60°C. Subsequently, the
AMC-101 (117 VAC), AMC-101B (234VAC), and
AMC-101D (24VAC) are mounted on an aluminum
extrusion and can deliver 5A at 60°C. All six versions are
available with standoff mounts only (insulating sheet is
included) which allows the units to be mounted directly to
the actuator housing or bracket. Note, the housing or
bracket is re-quired for heatsinking the AMC-101A,
AMC-101C, and AMC-101E 5A units.

• Built-in utility power supplies for powering a command pot, 4-20mA input or output
transmitter, and the feedback potentiometer.
• No external motor resistors are required.

When using this feature, certain precautions
should be observed. For applications using the 0-10V in-
put signal type, the unit cannot detect a loss of signal; do
not install jumper plugs JP2, JP3, and JP4 for these appli-
cations. When JP3 or JP4 are installed, the unit will turn
on one of the motor outputs when the input signal is lost;
if the actuator does not use limit switches, these selections
should not be used.
CALIBRATION
The non-interactive zero and span adjustments of
the AMC-100/AMC-101 allow for easy calibration once
the unit is installed. After insuring that the feedback po-
tentiometer and motor outputs are wired to provide a
proper feedback signal, as described under "ACTUATOR
(J1)", follow these steps to calibrate the unit (see Outline
for the location of the adjustments):
1 - Apply AC power to the unit, and set the command
input signal to minimum:
0V for 0-10V input type
1V for 1-5V input type
4mA for 4-20mA input type
2 - Adjust the "Zero" adjustment so that the actuator
moves to the desired closed position. If the de-
sired position cannot be achieved, check that the
feedback potentiometer provides a feedback sig-
nal as described under "ACTUATOR (J1)"; also,
check the position of the limit switches.
3 - If the actuator is hunting for position, turn the
"Deadband" adjustment clockwise until hunting
stops. If the actuator is not hunting for position,
turn the "Deadband" adjustment counterclockwise
until the actuator begins to hunt; then turn the
"Deadband" adjustment slightly clockwise until
hunting stops.
WARNING! Actuator failure may occur if the
"Deadband" adjustment is set to allow continuous
hunting. This can cause excessive wear of motor
bearings, geartrain, dynamic brake, and feedback
potentiometer. Hunting can also cause the inter-
nal temperature of the actuator housing to rise to a
level that exceeds the maximum rating of the
AMC-100/AMC-101, 60oC.

4 - Set the command signal input to maximum:
10V for 0-10V input type
5V for 1-5V input type
20mA for 4-20mA type
5 - Adjust the "Span" adjustment so that the actuator
moves to the desired open position. If the desired
position cannot be achieved, check the position of
the limit switch.
NOTE: The "Zero" adjustment is an offset set-
ting rather than an absolute setting. Should the
"Zero" adjustment be changed, the "Span" ad-
justment should be checked for the desired open
position. Setting of the "Span" adjustment has no
affect on the "Zero" adjustment.
6 - To check proper operation and linearity, set the
command signal to halfway:
5V for 0-10V input type
3V for 1-5V input type
12mA for 4-20mA input type
Verify that the actuator's position is midway be-
tween the open and closed positions.
REVERSE ACTING CALIBRATION
When converting a direct acting actuator to a re-
verse acting actuator, two changes in wiring must be
made:
1 - Reverse the feedback potentiometer wires con-
nected to J1-4 and J1-6.
2 - Reverse the motor output wires connected to J1-1
and J1-3.
NOTE: DO NOT reverse the input signal polar-
ity. Also, make sure that both wiring changes are
made - if only one is made, the actuator will run to
either full open or full closed.
After the wiring changes have been made, refer to CALI-
BRATION for setting the zero and span adjustments.
