Introduction
The CurrentWatch™ ECSD Series cur-
rent operated switches from Eaton’s
brand are DC current-operated switches.
They switch when the current level
detected through the aperture exceeds
the adjustable setpoint. The ECSD
Series accepts 12 VAC/DC or 24 VAC/
DC power. The outputs are isolated
from the input and power supply. The
ECSD Series can be ordered with either
a solid-state output or a Form C Relay
output.
The ECSD Series provides the same dependable indication of status
offered by the CurrentWatch ECS Series, but with the added benefit
of increased setpoint precision. A choice of three jumper-selectable
input ranges allow the ECSD Series to be tailored to an application,
providing more precise control through improved setpoint resolution.
Features such as isolated solid-state or mechanical relay outputs;
4-20 A, 10-50 A, and 20-100 A input ranges are standard.
Installation
Considerations for all ECSD 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 enclo-
sures.
•
Mounting can be done in any position or hung on a wire.
•
Be sure to leave at least one in. (2.54 mm) between the sensor
and other magnetic devices.
Quick Install Guide
The below steps can be followed to quickly install a CurrentWatch
ECSD Series switch.
1. Run the wire to be monitored through the aperture.
2. Connect power and output wiring:
a. Make sure the power supply matches specifications,
b. Ensure output load matches the output shown on the switch
label.
3. Adjust the setpoint.
a. Choose correct range by positioning the range jumper.
b. Use the potentiometer to adjust the setpoint.
Delay Type Low Range Mid Range High Range
On Delay 80 ms. 60 ms. 60 ms.
Off Delay 60 ms. 60 ms. 60 ms.
Setpoint Adjustment
The CurrentWatch ECSD Series features two setpoint adjustment
mechanisms.
•
First, select the setpoint range with the range jumper.
•
Then, fine tune the setpoint with the 11-turn potentiometer (pot).
The 11-turn pot is shipped from the factory set fully counter-clock-
wise to the lowest setpoint. Turning the pot clockwise will increase
the setpoint. The pot has a slip-clutch to prevent damage at either
end of its rotation. To determine where the adjustment is, turn the
pot all the way counter-clockwise. This will return it to the minimum
setpoint.
Important Setpoint Adjustment Notes
•
Normally Open (N.O.) output contacts are solid-state. Check out-
put status by applying a small load and then reading the voltage
drop across the contacts. An ohmmeter set on “continuity” will
give misleading results. Models with mechanical relays can be
accurately tested with an ohmmeter.
•
It is recommended the setpoint be adjusted to allow for normal
current/voltage variations.
•
These switches feature an adaptive hysteresis (deadband) of five
percent of the setpoint. This allows sensitivity at low setpoints
while eliminating dithering and output chattering at high setpoints.
Typical Adjustment Steps
1. Make sure all wiring is correct, all terminals are tight and that
power is on (look for the green power LED).
2. Move the jumper to the desired range. Then, turn the pot to the
minimum setpoint (11 turns counter-clockwise).
3. Have normal operating current running through the switch. The
output should be tripped since the pot is at its minimum set-
point. The red output LED should be on.
4. Turn the pot clockwise until the unit un-trips. This is indicated by
the red output LED turning off and the output switching.
5. Now turn the pot counter-clockwise slowly until the unit trips
again. It is now set at the current level being monitored.
a. To set underload, turn the pot about 1/8 turn further counter-
clockwise,
b. To set overload, turn the pot about 1/8 turn further clockwise.

Wiring Diagrams
Connect control or monitoring wires to the sensor. Use 12-22 AWG
copper wire and tighten terminals to 4.5 in.-lbs / 0.51 N·m maximum
torque. Be sure the output load does not exceed the switch rating.
CAUTION!
INCANDESCENT LAMPS CAN HAVE “COLD FILAMENT INRUSH” CURRENT OF
UP TO TEN TIMES THEIR RATED AMPERAGE. USE CAUTION WHEN SWITCHING
LAMP LOADS CONNECTED TO THE SOLID-STATE OUTPUT.
CAUTION!
DO NOT DISCONNECT OUTPUT TERMINALS UNDER LOAD.

Troubleshooting
Problem Solution
Switch is
always
tripped.
The jumper may be set in a range that is too low for current being moni-
tored. Move jumper to the correct range.
The setpoint may be too low. Turn pot clockwise to increase setpoint.
Switch may have been overloaded and contacts are burned out. Check
the output load, remembering to include inrush on inductive loads (coils,
motors, ballasts).
Switch will
not trip.
The jumper may be set in a range that is too high for current being
monitored. Move jumper to the correct range.
The setpoint may be too high. Turn pot counter-clockwise to decrease
setpoint.
Unit might not be powered. Check power supply, power wiring, and
green Power LED on switch.
Switch may have been overloaded and contacts are burned out. Check
the output load, remembering to include inrush on inductive loads (coils,
motors, ballasts).
