Introduction
The CurrentWatch™ EAC Series Powered
combines a current sensor and signal con-
ditioning electronics in a single package
for use in 120 V line-voltage or 24 VAC/DC
control power applications. The combina-
tion of these devices results in a single
unit with higher accuracy, fewer individual
terminations and a space-saving simplified
installation.
The EAC Series family of powered current
sensors are available in split-core enclosures with 4-20 mA analog
outputs. These sensors are average responding and intended for use
in constant or on/off load applications with sinusoid waveforms.
Eaton’s current sensor family encompasses a broad range of
products for cost-effective monitoring, status, and predictive main-
tenance. Downtime and costly repairs can be avoided by utilizing
Eaton’s products and technologies in your control systems.
Quick Install Guide
The below steps can be followed to quickly install a CurrentWatch
EAC Series Powered sensor.
1. Run the wire to be monitored through the aperture
2. Mount the sensor to a surface if needed
3. Connect output wiring, using up to 12 AWG copper wires
4. Choose the correct range by positioning the Range Jumper
Installation
Considerations for all EACP Series models…
•
These sensors can be located in the same environment as
motors, contactors, heaters, pull-boxes and other electrical enclo-
sures
•
Mounting can be done in any position or hung directly on a wire
with a wire tie
•
Be sure to leave at least 1.0 in. (25.4 mm) distance between sen-
sor and other magnetic devices
Considerations for split-core models only…
•
Press the tab in the direction
shown in the diagram to the right.
•
After placing the wire in the
aperture, press the hinged portion
firmly downward until a click is
heard and the tab pops out fully.
•
Keep split-core contact areas
clean. Silicon grease is factory applied on the mating surfaces to
prevent rust and improve performance. Be careful not to allow
grit or dirt into the grease in the contact area, particularly on core
mating surfaces of split core models. Sensor operation could be
impaired if mating surfaces do not have good contact. Check visu-
ally before closing.
Range Selection
The CurrentWatch EAC Series Powered sensors feature field select-
able ranges. The ranges are factory calibrated, eliminating time con-
suming and innacurate field setting of zero or span.
Setting Range
1. Determine the normal operating amperage of your monitored
current.
2. Select the range this is equal to or slightly higher than the nor-
mal operating amperage.
3. Place the Range Jumper in the appropriate position.
To open:
Press tab inward
towards hinge
Important:
Keep contact areas clean
Output Wiring
Connect control or monitoring wires to the sensor. Use up to 12
AWG copper wire and tighten terminals to 9 in.-lbs / 1.02 N·m maxi-
mum torque.
Connection Notes:
•
Deadfront captive screw terminals
•
Use 12-22 AWG solid or stranded
•
