Introduction
The CurrentWatch™ ECSTD
Series are a family of high
performance current-operated
switches with field-adjustable
time delay to help minimize
nuisance trips during start-up
and operation. Designed for
motor status applications where
setpoint accuracy and repeatability are critical, the ECSTD Series
offers a linear setpoint characteristic and constant hysteresis.
Standard features include self-powering, jumper-selectable ranges
and a choice of outputs and housing styles cases. Models are avail-
able which provide N.O. or N.C. AC contacts or solid-state N.O.
or N.C. “universal” contact outputs which can switch AC or DC.
Contact action can be delayed for up to 15 seconds by using the
Time Delay Adjust potentiometer.
Eaton’s current sensor family encompasses a broad range of
products for cost-effective monitoring, status, and predictive main-
tenance. Downtime and costly repairs can be avoided by utilizing
Eaton’s products and technologies in your control systems.
Installation
Considerations for all ECSTD 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 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 below to open the sensor.
•
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 per-
formance. 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
Quick Install Guide
The below steps can be followed to quickly install a CurrentWatch
ECSTD Series switch.
1. Run the wire to be monitored through the aperture.
2. Mount the sensor.
3. Connect output wiring.
a. Use up to 14 AWG copper wires,
b. Ensure load matches the output shown on the switch label.
4. Adjust the setpoint:
a. Choose correct range by positioning the range jumper
(removed for low, across two appropriate pins for medi-
um, or high),
b. Use the potentiometer to adjust the setpoint.
Setpoint Adjustment
The CurrentWatch ECSTD Series setpoint and time delay are adjust-
ed through two four-turn pots (on split-core models) and 15-turn pots
(on solid-core models). The unit comes from the factory with set-
point and time delay set to the lowest level (fully counter-clockwise).
Turning the pots clockwise will increase their value. All pots have
a slip-clutch to prevent damage at either end of their 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
•
Output contacts are solid-state. Check output status by applying
the appropriate voltage to the contacts and reading the voltage
drop across the contacts. An Ohmmeter set on “continuity” will
give misleading results.
•
It is recommended the setpoint be adjusted to allow for the usual
utility company voltage variations of 10 to 15 percent.
Typical Adjustment Steps
1. Identify expected Input Range and position jumper accordingly.
For LOW range, remove jumper entirely. For MID or HIGH range,
place jumper over proper two pins.
2. Turn the setpoint pot to the minimum value (four turns for split-
core models and fifteen turns for solid-core models).
3. Have normal operating current running through the switch. The
output should be tripped because the pot is at its minimum set-
point. For units with LED, it should be flashing fast (two to three
times per second).
4. Turn the pot clockwise until the unit un-trips. This is indicated by
the slow flashing of the LED (once every two to three seconds),
or by the changing of the output switch status.
5. Now turn the pot counter-clockwise slowly until the unit trips
again.
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.
6. Adjust the time delay of the contact action in the same fashion.
Increase time delay by turning the pot clockwise. For split-core
models, each quarter-turn corresponds roughly to one second of
delay time. Expect ten turns for a 15 second delay.

Troubleshooting
Problem Solution
Switch is
always
tripped.
The setpoint may be too low. Turn pot clock-wise to increase set-
point.
Switch may have been overloaded and contacts are burned out.
Check the output load, remembering to include inrush on inductive
loads (coils, motors).
Switch will
not trip.
The setpoint may be too high. Turn pot counter-clockwise to
decrease setpoint.
For split core models, the core contact area may be dirty. Open the
sensor and clean the contact area.
The monitored current may be below the minimum required. Loop the
monitored wire several times through the aperture until the “sensed”
current rises above the minimum. The sensed amps equals “actual
amps” multiplied by the “number of loops.” Count loops on the
inside of the aperture.
Switch may have been overloaded and contacts are burned out.
Check the output load, remembering to include inrush on inductive
loads (coils, motors).
