ECAI00-II GENERAL DESCRIPTION
The ECAI00-II electronic three-phase relays are specially designed for the protection of air conditioning and refrigeration compressors and ventilation motors from the causes of current, voltage and power failures, all with enhanced reliability and with connectivity.
WARNING
Only qualified electrical technicians with knowledge of overload relays and associated machinery should perform the installation, starting up, and maintenance of the system. Adhere to all local and national electric codes. Disconnect all electrical
power at the source prior to any installation or maintenance work. Failure to comply could result in equipment damage, personal injury, OR even death.
WARNING: This product may start automatically, the user must take cautions to avoid hazards to people.
CAUTION: This product has been designed for industrial environment. Use of this product in residential enviroment may cause unwanted electromagnetic disturbances in which casethe user may be required to take adequate mitigation measures. CAUTION: An incorrectly applied or installed ECAIOO-II can result in damage to the components or reduction in product life. Wiring or application errors, or operating/storing in excessive ambient temperatures may result in malfunction of the ECAIOO-II. -

ECAI00-I11 DIN RAIL AND FLAT SURFACE MOUNTING
CAUTION: ECAI00-II must be installed in an accessible position free from dust, dirt, dampness and vibrations. Allow enough space for air circulation around the enclosure and easy access to all operator controls. Indoors Use only. |
3.1 Instructions for Mechanical Installation
Place ECAIOO-II at an inclined with is back side placed toward the upper edge
of the DIN Rail and push down ECAIOO-II relay, as shown in figure until it
CLICKS on the rail. 3.2 Instructions for Mechanical Installation
a) Take off the two (2) attachable mountings ear located at back side of
ECAIOO-II, insert and slip both attachable mounting ears into the ECAIOO-II
back side grooves. b) Place ECAS00-II over a flat surface panel and mount it
using (2) #8 x 1/2″ screws Recommendiation for Flat Surface Mounting:
Make two (2) holes (5/32″) on panel surface before installing.Refer Section 5
for dimensions.
NOTICE: When ECAIO0-II is set to MANUAL Start mode, the indicator lights
(Red LED 1, Red LED 2, Red LED 3) will be lit up sequentially after the Start
Delay (TC) is over. The condition remains until the user presses the START
Push button to re-start.
ECAIOO-II DISMOUNTING INSTRUCTIONS
WARNING: Disconnect power supply (Circuit Breaker OFF) A and electrical
wiring before dismounting ECAIOO-II.
Electrical shock will result in death or serious injury.
8.1 Instructions for Mechanical Dismounting (DIN RAIL)
a) Using a Flathead screwdriver, pull downward the mounting bracket that you
can see at the rear and bottom side of the ECAIOO-II, as shown In figure. b)
With screwdriver at position (2), pull out ECAIOO-II from DIN Rail as shown in
figure: Recommendation for DIN Rail Dismounting:
Pull downward 2 mm with a soft movement when using screwdriver for
dismounting. Strong movement could break the supporting bracket
8.2. Instructions for Mechanical Dismounting (FLAT SURFACE)
a) Unscrew both screws fixed on Flat Surface through attachable mounting ears

4.2.1 ECAIOO-II 208/220 VAC Models
4.2.2 ECAIOO-II 440/480 VAC Models
Requires auxiliary control voltage from 24 to 250 VAC.
Recommendations for Wiring:
- Avoid overtightening M2.5 screw terminals during wiring of connections. Torque max. 4.5 Ib-in (5.18 kgf-cm)
- Wire Strip Length 6-7 mm.
- Screw Terminal wire size: D AWG 10 (4 mm?) B AWG 18.

- Connect L| L2 L3 terminal for Voltage input in parallel connection before line starter circuit through Contactor (as shown in Basic Diagram Installation).
- Feed the the three phases going to the motor through the three current sensing holes. Using less than three wires may cause undesired current unbalance
ECAIOO-I1 GENERAL DIMENSIONS
ECAI00-11 ADJUSTMENT
CAUTION: By means of an Ammeter, make sure that the Operational Current
(I) is less than FLA (Full Load Amperes) indicated at the motor nameplate.
Failure to comply may result in damage to the motor. _
ATTENTION: Any accidental or Intentional change of setting knob positions
after overload asjustment will cause varlations In the ECA100-II’s protective
performance from previous setup. In this case, repeat procedure for ECAIO0-II
adjustment indicated In Section 6.1
6.1 Procedure for Overload Adjustment
ATTENTION: You should follow this procedure with the motor running at
full load conditions, according to the rated values indicated on Motor Name
Plate.
a) Turn OFF the circuit breaker. NOTE: Make sure that wiring is according
to connection diagram (see item 4.2).
b) Slide the AUTO/MANUAL start mode slide – switch to MANUAL position.
¢) Turn ON the circuit breaker. (The motor remains OFF as the contactor is
open through deactivation of the ECANO-II) d) Turn right che Current setting
knob (FLA) up to the maximum value. e) Press the START push button and hold it
pressed (motor starts running and reaches steady-state operation) while you
execute steps .
f) and (g). f} Slowly turn left the Current secting knob (FLA) undil the green
LED turns ON. At this point, the adjusted level is the actual Motor
Operational Current. g) Slowly tum right the current setting knob (FLA) up to
desired protection level: h) Use AUTO/MANUAL start mode slide-switch to select
the desired motor start mode.
NOTICE: Incase the AUTOMMANUAL start mode side – switchis set on MANUAL
and the ECAIOG-II relay wips dus to any fault decoction, you shall press START
push button to re-activate the Contactor or Line Starter Circuit.
Although the AUTO/MANUAL start made slide – switch is set on AUTO, pressing
START push bumon is required @ three (3) current fadures have appeared mn less
than 30 minutes and qualilied technicians have detected and solved causes of
failures. I)Using a fiat screwdriver, turn the TC setting knob unsil you set
the start delay datired (TC & che ore between Vokage fauk recovery and restart
the system according to appication needs),
ECAI00-II OPERATION
ECAIO0-8 constantly supervises motor current and line volcage.
‘When any harmful condidon occurs, the ouput ts deactivated until the faulc
disappears and che mocor has completely cooled. Specific timing such | as
Start Up Delay (TC) is incorporased for automatic restart mode, to prevent
nuisance tripping due to rapid power fluctuations. In the event of three
current failures in less than thirty (30) minutes, che output is deactivated
until manual restart is done, Checking causes of three successive failures is
recommended before restarting because it can be an indication of mechanical
problems such as the condensing unit not being able to dissipate heat
adequatedy or that there is a problem in the wiring operation, of a damage to
the contractor
ECANOO-M provides two {2} sorting knobs co select che maximum allowed current
