Introduction
The CurrentWatch™EAC Series combine a
current sensor and signal conditioner into
a single package. The EAC Series are
available in solid or split core with 4-20 mA,
0-5 VDC or 0-10 VDC outputs.
The CurrentWatch EACR Series
provide “True RMS” output. Available
only with a 4-20 mA output. Select EACR
Series sensors for applications involving
variable speed or SCR-controlled loads.
To open:
Press tab inward
towards hinge
Important:
Keep contact areas clean
Installation
Considerations for all EAC and EACR Series models…
• Run wire to be monitored through the aperture (opening) in the
switch body.
• 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.
Quick Install Guide
The below steps can be followed to quickly install a CurrentWatch
EAC or EACR Series switch.
1. Run the wire to be monitored through the aperture.
2. Mount the sensor to a surface, if needed.
3. Connect output wiring:
a. Use up to 14 AWG copper wires.
b. If using a 0-5 or 0-10 VDC output model, make sure output
load is at least 1 megohm.
c. If using a 4-20 mA output model, make sure loop voltage is
correct (see “Output Wiring” section).
4. Select range:
a. Choose the correct range by positioning the Range Jumper.
Output Wiring
Connect control or monitoring wires to the sensor. Use up to 14
AWG copper wire and tighten terminals to 7 in.-lbs / 0.79 N·m
maximum torque. Be sure the output load or loop power does not
exceed the sensor rating.
Connection Notes:
• Captive screw terminals.
• Use 14-22 AWG solid or stranded.
• Observe polarity.
• See label for ranges and jumper positions.

Notes for Voltage Output Models:
• Recommended output load greater than 1 megohm
• Add 1.3% error for 100 kilohm
Loop Voltage Requirements:
• EAC Series: Min. Loop Voltage = 5 V + (Loop Resistance x 20 mA)
• EACR Series: Min. Loop Voltage = 12 V + (Loop Resistance x 20 mA)

Range Selection
The CurrentWatch EAC Series sensors feature field selectable rang-
es. The ranges are factory calibrated, eliminating time consuming
and inaccurate 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.

Troubleshooting
Problem
Solution for Current
Output Models
Solution for Voltage
Output Models
Sensor has no
output.
Power supply is not properly
sized. Check power supply
voltage and current rating.
Monitored load is not AC or is
not on. Check that the moni-
tored load is AC and that it is
actually on.
Polarity is not properly matched. Check and correct wiring
polarity.
For split core models, the core contact area may be dirty. Open
the sensor and clean the contact area.
Output signal is
too low.
The jumper may be set in a range that is too high for current
being monitored. Move jumper to the correct range.
The load current is not
sinusoidal (EAC Series only).
Select an EACR Series sen-
sor that works on distorted
waveforms.
Output load may be too low.
Check output load, making
sure it is at least 100 kilohm
and preferably 1 megohm.
Monitored current is below minimum required. Loop the
monitored wire several times through the aperture until the
“sensed” current rises above minimum. (‘Sensed Amps’ is
equal to ‘Actual Amps’ multiplied by the ‘Number of Loops.’)
Output signal is
always at maxi-
mum.
The jumper may be set in a range that is too low for current
being sensed. Change the jumper position.
Output signal is
always at 4 mA.
Monitored load is not AC or is
not on. Check that the moni-
tored load is AC and that it is
actually on.
