Introduction
The CurrentWatch™ EDC Series
combines a hall effect sensor and a
signal conditioner into a single, compact
package for use in DC current applica-
tions up to 300 A. The EDC Series has
jumper selected current input ranges and
industry standard outputs: 4-20 mA,
0-5 VDC and 0-10 VDC. Split core models provide for quick and easy
installation.
ote:N This manual only covers split-core versions of the EDC Series. For the
solid-core manual, use publication P51926.
Eaton’s current sensor family encompasses a broad range of prod-
ucts for cost-effective monitoring, status, and predictive mainte-
nance. 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
EDC Series sensor.
1. Run the wire to be monitored through the aperture, being sure
monitored current flow matches arrows on the sensor.
2. Mount the sensor to a surface if needed.
3. Connect output wiring:
a. Use up to 14 AWG copper wires, tightening terminals to
4 in.-lbs / 0.45 N·m maximum of torque,
b. For current output models (4-20 mA), make sure output load
is no more than 800 ohms,
c. For voltage output models (0-5/0-10 VDC), make sure output
load is at least 10 kilohms.
4. Connect power using the appropriate power supply.
5. Select range by positioning the Range Jumper.
Installation
Considerations for all EDC Series models…
• Run wire to be monitored through the aperture (opening) of the
sensor.
• Be sure monitored current flows in the same direction as the
arrow on the sensor (the arrow is located just above the hinge,
with a plus symbol on the left and a minus symbol on the right).
• These switches 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 one in.(2.54 mm) distance between sen-
sor and other magnetic devices.
• 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
visually before closing.
To open:
Press tab inward
towards hinge
Important:
Keep contact areas clean
Range Selection
The CurrentWatch EDC 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.
Output Wiring
Connect control or monitoring wires to the sensor. Use up to 14
AWG copper wire and tighten terminals to 4 in.-lbs / 0.45 N·m maxi-
mum torque.
Connection Notes:
• For current output models, the current loop is powered by the
sensor. Maximum loop impedance is 800 ohms.
• For voltage output models, the signal is powered by the sensor.
Minimum output load (impedance) is 10 kilohms.
• Deadfront captive screw terminals.
• Use 12-22 AWG solid or stranded.
• Remove jumper entirely for Low Range operation.
• Observe polarity.
Troubleshooting
Problem
Solution for Current
Output Models (4-20 mA)
Solution for Voltage
Output Models (0-5/0-
10 VDC)
Sensor has no
output.
Monitored load is not DC or is not on. Check that the moni-
tored load is DC 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.
Power supply is inadequate. Check power supply. Make sure
it is of sufficient voltage with all loads at maximum. The cur-
rent draw of EDC Series sensors is 2.0 VA.
Output load is too high.
Check output load, being sure
it is no more than 800 ohms.
Output load is too low. Check
output load, making sure it is
at least 10 kilohms.
Output signal is
always at
maximum.
The jumper may be set in a range that is too low for current
being sensed. Change the jumper position.
