Scaling
If you are using PAC Control, when you configure the points on
SNAP power monitoring modules, you must scale them to
match the CT you use. Scaling must be accurate for the
resulting data to be accurate. The examples starting on
can help you determine the correct values for your CT and
module.
IMPORTANT: For all installations of 85 to 300 VAC (or 85–250
for the SNAP-AIPM), both Actual and Scaled Volts (point 0 on
all modules, plus points 4 and 8 on the SNAP-AIPM-3 and
SNAP-AIPM-3V) should remain at the default: 0–250 VAC for
the SNAP-AIPM and 0–300 VAC for the SNAP-AIPM-3 and
SNAP-AIPM-3V.
However, for installations over 300 VAC (250 for the SNAP-
AIPM), you will need to scale these points. For help, see
“Scaling Example 2: SNAP-AIPM with PT” on page
“Scaling Example 4: SNAP-AIPM-3 with PT” on page
“Scaling Example 6: SNAP-AIPM-3V with PT” on page
that these examples of higher line voltage require you to use a
step-down potential transformer.
Steps for Scaling Modules in PAC Control
NOTE: SNAP-AIPM-3 and SNAP-AIPM-3V require brain firmware
9.1b or newer and PAC Control 9.1a or newer.

For the SNAP-AIPM, you see four points. For the SNAP-
AIPM-3 (shown above) or the SNAP-AIPM-3V, you see 14.
You must configure each point.
In PAC Control, open your strategy. In the Strategy Tree,
right-click the I/O unit containing the power monitoring
module and choose Configure from the popup menu.
Click the I/O points button. Double-click the module’s
position number on the rack. Click Analog Input and
then choose the module’s part number from the list.
Click OK.
Click the plus sign next to the module to open its points.

Double-click point 0, the voltage input, and give it a
name. If you’re not using a PT, leave the scaling as is. The
following image illustrates point 0 for Scaling Example 3

Click OK.
Continue to configure each point on the module,
following the calculations in the examples:
