Wiring

Pass motor leads through Motor Insight overload relay
CT pass through. If multiple passes of the motor leads
are required, make sure that the current flow is from
top to bottom through Motor Insight overload relay. If
external CTs are used, pass the 5 amp secondary of the
external CTs through Motor Insight overload relay inter­nal CTs. See Table 3A for wrap and CT multiplier.

CAUTION!

THE OPENING OF BRANCH-CIRCUIT PROTECTIVE DEVICE MAY BE AN INDI­CATION THAT A FAULT HAS BEEN INTERRUPTED. TO REDUCE THE RISK OF
FIRE OR ELECTRIC SHOCK, CURRENT-CARRYING PARTS AND OTHER COM­PONENTS OF THE CONTROLLER SHOULD BE EXAMINED AND REPLACED
IF DAMAGED. IF BURNOUT OF THE ELEMENT OF AN OVERLOAD RELAY
OCCURS, THE COMPLETE OVERLOAD RELAY SHOULD BE REPLACED.

ATTENTION

LE DÉCLENCHEMENT DU DISPOSITIF DE PROTECTION DES DÉRIVATIONS
PEUT SIGNIFIER QU’UN COURANT DE DÉFAUT A ÉTÉ INTERROMPU. POUR
RÉDUIRE LE RISQUE D’INCENDIE OU DE CHOC ÉLECTRIQUE, LES PIÈCES

GRILLE, LE RELAIS DE SURCHARGE ENTIER DOIT ÊTRE REMPLACÉ.

Initial Configuration

On initial power-up, Motor Insight overload relay displays a “rOF”
message. This indicates that the fault relay is OFF. Configure the
device for the application prior to resetting the device.

To turn the fault relay OFF, press the Trip button.

Programming Set Points

Motor Insight overload relay is easy to configure. Viewing and
editing protection set points can be performed in the Protection
and Operation Mode. The following steps outline the procedure
for modifying any of the set points.

Step 1: Press Mode button until Protection or Operation
Mode Led is lit.

Mode

Step 2: Press Up or Down button until the desired O/P LED
is lit. Display shows the current parameter value.

Step 3: Press the Edit/Save button. The display now shows
the parameter value but is now flashing.

Step 4: Use the Up/Down button to adjust the parameter
to the desired value.

Step 5: Press the Edit/Save button. The Display now shows
the new parameter value that has been saved by the device.

Configuring the Thermal Overload Protection Feature

Motor Insight overload relay features electronic motor overload pro­tection. This feature protects the motor and power wiring against
overheating caused by excessive current for extended periods
of time.

The trip current is programmed by entering the motor full load
amperes (FLA) using the Motor FLA parameter. The trip class
(5 to 30) is set using the Trip Class parameter.

The FLA range of the overload relay can be modified with the use
of multiple turns through the CTs or with the use of external CTs.
Use the following tables to appropriately configure the device for the
application. If the application requires the FLA range to be extended,
program the CT multiplier first.

Important Note: After an overload trip, Motor Insight relay cannot be reset
until the thermal model decays to a thermal capacity that is thermally safe for
a motor restart. Cycling the power does not reset the thermal model.
