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 or as
noted on the figure to the right on this page.
2. Mount the sensor to a surface, if needed.
3. Connect output wiring:
a. Use up to 14 AWG (2.5 mm2) copper wires, tightening termi-
nals to 5.3 in.-lbs / 0.60 N·m of torque.
b. For current output models, make sure output load is no more
than 500 ohms.
4. Connect power using the appropriate power supply.
5. Select the correct 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.
• Care should be taken to ensure current flow is in accordance with
any directional arrows on the sensor and as noted in the figure on
the right of this page.
• 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.
• For optimal performance, ensure the unit has been energized for a
period of 20 minutes prior to sensing operation.
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.
Wiring and Mounting Information
Connect control or monitoring wires to the sensor. Use up to 14
AWG copper wire and tighten terminals to 5.3 in.-lbs / 0.60 N·m
maximum torque.

Connection Notes:
• The current loop is powered by the sensor. Maximum loop
impedance is 800 ohms.
• Ensure the direction of the monitored current is the same as the
direction shown on the diagram. The unipolar output design will
not operate properly if the current is opposite the direction of the
arrow.
• Use 26-14 AWG copper wire.
• Screw thread is M3 and screw torque is 5.3 in.-lbs / 0.60 N·m.
• Remove jumper entirely for Low Range operation.
• Observe polarity.

Troubleshooting
Problem
Solution for Current
Output Models
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.
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 500 ohms.
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.
