INSTALLATION
READ THESE INSTRUCTIONS BEFORE YOU BEGIN INSTALLATION.
Ground yourself before touching board. Some components are static sensitive.
MOUNTING:
Circuit board may be mounted in any position. If circuit board slides out of snap track, nonconductive “stop”
may be required.
Use only fingers to remove board from snap track. Slide out of snap track or push against side of snap track
and lift that side of the circuit board to remove. Do not flex board or use tools.
NOTE

POWER CONNECTIONS
Be sure to follow all local and electrical codes. Refer to wiring diagram for connection information.
1. 120 VAC – Be sure to make all connections with the power off, connect 120 VAC power
supply.
2. If the 120 VAC power is shared with devices that have coils such as relays, solenoids, or other
inductors, each coil must have a Metal Oxide Varistor, or other spike snubbing device across each
of the shared coils. Without these snubbers, coils produce very large voltage spikes when deenergizing that can cause malfunction or destruction of electronic circuits.

WIRING
The AIM3 is factory set as follows, unless otherwise specified:
Voltage Input signal, 0-5V (source)
1:1 Input to Output Signal Ratio,
Voltage Output Signal, 0-5V (source)
AIM3 input and output ranges, as well as offset, can be selected by jumper shunt in the field.
STEP 1) WIRING CONNECTIONS
With the power OFF, make the following connections:
Connect a 120 VAC power supply to the “Supply 120 VAC” terminals of the AIM3. Connect the input signal
common to the IN (-) terminal of the AIM3, and the input signal positive to the IN (+) terminal of the AIM3.
Connect the OUT signal common (-) and the OUT signal positive (+) to their respective terminals on the
controlled device.
SETTING AIM3 INPUT
Set jumper Shunt J1 and J2 for INPUT signal ranges and offset.
Set chart on page 1.
SETTING AIM3 OUTPUT
Set jumper Shunt J3 and J4 for OUTPUT signal ranges and offset.
Set chart on page 1.
POWER-UP AND CHECKOUT
STEP 2) POWER UP
Turn on the 120 VAC power supply. Both power indicators on the AIM3 will light.
STEP 3) OPERATION
The AIM3 will now operate according to the standard settings from the factory or settings made by jumper
selection. If no changes from the factory settings were made, the AIM3 will accept a 0 to 5 volt DC input
signal and produce an isolated and proportional 0 to 5 volt DC output signal. For example, a 3.50 volt input
signal will produce a 3.50 volt DC output signal.
