INTRODUCTION
The CurrentWatch™ ECS7 Series current
switches are designed for overload,
underload or operating window applications.
Upon sensing an average operating current,
the ECS7 Series self-learns and establishes a
limit-alarm trip point based on plus or minus
15 percent of the average expected current
being monitored. The ECS7 Series is available
in solid or split core housing styles.
The ECS7 Series magnetically isolated solid state output contacts are
rated for 0.30A @ 135V AC/DC. This "universal" output makes this
product especially well suited for PLC control systems or a variety of
load connections.
Eaton's current sensor family encompasses a broad range of products
for cost-effective monitoring, status, and predictive maintenance.
Downtime and costly repairs can be avoided by utilizing Eaton's
products and technology in your control systems.
Note: Unless otherwise specifi ed, the term "load" refers to the
current being monitored.

INSTALLATION
Considerations for all ECS7 Series models...
• Run wire to be monitored through the aperture (opening) in the
switch body.
• These switches can be located in the same environment as
motors, contactors, heaters, pull-boxes and other electrical
enclosures.
• Mounting can be done in any position or hung directly on a wire
with a wire tie.
• Be sure to leave at least one inch distance between sensor 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
fi rmly 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.
QUICK INSTALL GUIDE
The below steps can be followed to quickly install a CurrentWatch™
ECS7 Series switch.
1. Run the wire to be monitored through the aperture
2. Mount the sensor
3. Connect output wire to the solid state relay terminals
a. Use up to 14 AWG copper wires
b. Don't exceed output rating
4. Slide the Function Switch from "CLR" to "RUN"
5. Turn load "on", equipment is now energized and sensor is
calibrated
• Note: Refer to the LED Indication table on page two for switch
operation.
WIRING DIAGRAM
Connect control or monitoring wires to the sensor. Use up to 14 AWG
copper wire and tighten terminals to 7 inch-pounds torque. Be sure the
output load does not exceed the solid state output rating.
CAUTION! Incandescent lamps can have "cold fi lament inrush"
current of up to ten times their rated amperage. Use caution when
switching lamps.
