Peaktronics AMI-103 User manual

PEAKTRONICS
The Peaktronics AMI-103 AC Motor Interface is
used to interface common electrical control signals to AC
actuators. The unit provides the motor drive circuits, pro-
tection circuits, and isolation between the control inputs
and motor outputs. A wide range of external control sig-
nals can be used to Open and Close the actuator. The unit
accepts commonly used 120VAC signals from PLC mod-
ules, relay circuits, triac outputs, or solid state relay cir-
cuits. Alternatively, signals from a number of electronic
sources, including TTL, CMOS, analog drivers, open col-
lector outputs, and low voltage AC outputs, can be used.
The unit has a built-in repeat cycle timer that can
be independently enabled or disabled for Open and Close.
The timer can be adjusted for 0.1 to 2 seconds "ON" time
and for 0.5 to 10 seconds "OFF" time. Since some AC
motors cannot be switched instantly from open to close
operation, the unit provides an adjustable input delay fea-
ture.
The unit can be configured for 2-wire or 3-wire
control. In 2-wire control, the control signal is applied to
the Open input to drive the actuator open. When the con-
trol signal is removed, or driven to 0V, the actuator will
automatically close. In 3-wire control, both control sig-
nals (Open and Close) are used to drive the actuator to-
ward open or closed as desired. When both signals are
removed, or driven to 0V, the actuator remains at its last
position.
The unit also features a red LED indicator (for the
open output), a green LED indicator (for the closed out-
put), an on-board fuse, two removable screw terminal
strips (for easy servicing), and on-board switches to man-
ually open or close the actuator. An auxiliary +24VDC
power output (that is isolated from the motor and control
signals) can be used to power a 4-20mA or 0-5 / 10V

transmitter. A transmitter (such as the Peaktronics XMA-
105 or XMA-106) can be used to provide a position feed-
back signal from a feedback potentiometer (such as the
Peaktronics POT-102).
The unit comes with standoff mounts and includes
an insulating sheet that allows the unit to be mounted di-
rectly to the actuator housing or bracket. The unit is rated
for 5A at 60°C when properly mounted to a metal bracket
or metal actuator housing. The AMI-103 is rated for
117VAC ±10%, the AMI-103A is rated for 234VAC
±10%, and the AMI-103B is rated for 24VAC ±10%.

DESCRIPTION
The AMI-103 comes in three versions to accom-
modate different voltage applications. The AMI-103 is
rated for 117VAC ±10%; the AMI-103A is rated for
234VAC ±10%, and the AMI-103B is rated for 24VAC
±10%. The units come with standoff mounts for direct
mounting to a bracket (insulating sheet is included).
The AMI-103 units are rated for 5A motors when
properly mounted to a suitable metal plate or bracket. To
provide sufficient heatsinking, these units require screw
mounting through all four standoffs.
CAUTION ! These units are intended to be
mounted in an appropriate enclosure to avoid electrical
shocks. High voltages are present on the outside of the
unit when power is applied. AC power should be discon-
nected prior to any wiring of these units. A heater and
thermostat should be used where condensation may occur.

POWER / SIGNAL (J2)
Power is connected to pins 1, 2, and 3 as shown in
the Block Diagram. The fuse installed on the unit is rated
for maximum output current that can be safely delivered
by the AC outputs. To prevent damage to the unit, re-
placement fuses must not exceed a rating of 6.3A. Small-
er fuse sizes can be used with smaller motors - consult the
actuator manufacturer for appropriate fuse size and type.
The control signal to open the actuator is connect-
ed to either pin 7 or pin 9 (do not connect both inputs at
the same time) using pin 5 (OPEN COMMON) as the re-
turn. The close control signal is connected to either pin 6
or pin 8 (do not connect both at the same time) using pin
4 (CLOSE COMMON) as the return. The AC HI inputs
(pins 6 and 7) are suitable for 120VAC control signals,
while the DC/AC LO inputs are used for either DC elec-
tronic signals (such as TTL, CMOS, etc.) or AC control
signals up to 90VAC. Open collector control signals can
also be used - see Wiring Diagrams for details.
Pin 11 of J2 provides an auxiliary +24VDC output
which can be used to power an output transmitter. SIG-
NAL GND (pin 10) is used as the return line for the
transmitter. SIGNAL GND (pin 10), OPEN COMMON
(pin 5), and CLOSE COMMON (pin 4) are isolated from
the motor outputs on J1 as well as from each other. Pin 4
and 5 should not be connected to pin 10 when using con-
trol signals that are not isolated from the AC power line
(pins 1, 2, and 3).
MOTOR (J1)
Pin 1 should be connected to the motor winding
that moves the actuator toward the open position, and
conversely, pin 3 is connected to the winding that moves
the actuator toward the closed position. Pin 2 is the neu-
tral or common wire to the motor windings. The AMI-
103 is suitable for powering most dynamic brakes used
with electric actuators; however, consult the actuator
manufacturer for more information.
OUTPUT INDICATORS
The AMI-103 units have on-board indicators that
identify when one of the motor outputs is turned on.
When the open output is turned on, the red LED indicator
will turn on, and when the close output is turned on the
green LED indicator will turn on (see Outline).
Many actuators are equipped with limit switches
at the open and closed positions which are intended to dis-
connect power to the motor to prevent mechanical dam-
age. For this reason, it is possible that the AMI-103 will
indicate that one of the motor outputs is turned on when
the actuator is not in motion. However, it should be noted
that when the indicator is on, power is applied to the mo-
tor output.
INPUT DELAY
Since some AC motors do not operate correctly
when power is instantaneously switched between the
Open and Close windings, the AMI-103 provides an input
delay. If one output is on and the control signal inputs are
switched to reverse the motor, the unit will delay turning
on the other output. This delay is adjustable; see Specifi-
cations under "Control Adjustments" for delay period and
Outline for location of the adjustment. When both outputs
are off and a control input signal is applied, the Input De-
lay setting causes a delay in turning on the associated out-
put. If the control signal is removed before the end of the
delay period, the associated output will not turn on.
OPEN and CLOSE SWITCHES
The AMI-103 provides on-board switches that
allow manual operation from the unit - see Outline for
location of the switches. Pressing the open switch will
turn on the Open output (J1 pin 1), while pressing the
close switch turns on the Close output (J1 pin 3). Since
the OPEN and CLOSE switches replace the control signal
inputs, the Input Delay function effects the switch opera-
tion in the same manner as a control signal - refer to IN-
PUT DELAY for more details.
To protect against turning on both outputs at the
same time, the AMI-103 will not turn on one of the out-
puts until the other output has turned off. Additionally, if
both control signals are applied at the same time, the unit
will turn off both outputs. This is true of any combination
of control signals or on-board switch operation. For ex-
ample, if a PLC is applying a control signal to the CLOSE
input while someone is pressing the open switch, both
outputs will be turned off.
2-WIRE / 3-WIRE CONTROL (JP5)
JP5 is used to configure the unit for either 2-wire
or 3-wire control - see Outline for location and setting of
JP5. In 3-wire control, the Open input signal is used to
turn on the Open output (J1 pin 1), and the Close input
signal is used to turn on the Close output (J1 pin 3).

AMI-103
PEAKTRONICS 5
In 2-wire control, only the Open input signal is
used, and the Close input terminals (J2 pins 4, 6, and 8)
must not be connected. The Close output will always be
turned on until the Open input signal is applied, at which
time the Close output is turned off and the Open output
will turn on. When the Open input signal is applied, the
manual Open switch will have no effect, while the manual
Close switch will turn off both outputs. When the Open
input signal is not applied, the manual Close switch will
have no effect, while the manual Open switch will turn off
the Close output and turn on the Open output.
REPEAT CYCLE TIMER
The AMI-103 has a built-in repeat cycle timer that
can be used to adjust the actuator speed. The timer auto-
matically cycles the output on and off whenever the asso-
ciated control input is applied. The ON time is adjustable
from 0.1 to 2 seconds, while the OFF time is adjustable
from 0.5 to 10 seconds. The timer function can be ena-
bled or disabled for each output independently by in-
stalling jumpers for the desired operation. See Outline for
location of adjustments and jumpers.
