TO SET ADJUSTABLE OUTPUT SPANS
If your output span is not a listed preset, set the span
DIP switches 1 through 4 to one of the three
adjustable ranges (just above in bold), and the oset
switches to the adjustable range by placing switch 8
ON, and 5,6,7 OFF. Give the AIM2 the maximum input
signal and adjust the SPAN pot until the required span is reached on the output terminals.
Three preset output signal osets are available. These will raise the entire span by the amount indicated,
above zero. For example, an 8V span with a 2V oset will give you a 2 – 10V output signal. If your oset (or
minimum output) is zero, set switch 5 ON and switches 6,7,8 OFF. See Table 6.
ADJUSTABLE OUTPUT OFFSETS
If your oset is not 0, 1, or 2 volts, you will need to adjust for your oset. The oset can be adjusted from 0
to approximately 10V.
Adjustable: 8 ON………………...5,6,7 OFF
Generate the minimum input signal at the input terminals IN and COM and calibrate the output OFFSET
pot until the oset required is reached (check with a voltmeter at output terminals OUT and COM).
From this point on, no further DIP switch changes are necessary. Toggle back and forth between the
maximum and minimum to check the accuracy of the calibration. If the span (or maximum of the output)
needs adjustment, turn the span pot. If the oset (or minimum) needs adjustment, turn the oset pot.
Repeat until calibrated correctly.
POWER UP AND CHECKOUT
STEP 2) POWER UP
Turn on the 24 VAC power supply. Both power indicators on the AIM2 will light.
STEP 3) OPERATION
The AIM2 will now operate to your specications, or the standard settings from the factory. If no eld
calibrations were made, then the AIM2 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.
