Effective 9/04
Accuracy is obtained by three closely coupled current sen-
sors in combination with a microprocessor that counts
units of the line current squared (I
2
), the heating effect
within the motor. The sensors are coils wound in the form
of toroidal helixes around a customized iron core with a
controlled air gap. This combination of coil, core, and air
gap results in greater accuracy than thermal overload re-
lays, without the fuss of heater elements. The stored count
decreases whenever the line current is less than the maxi-
mum motor full load current specified for the overload set-
ting selected. This decrease represents the natural motor
winding cooling that occurs as the motor runs at full load
current or less.
Where an Advantage starter is equipped with an optional
internal or external trip indicator, the LED in the indication
will blink every 4 to 5 seconds when power is applied to
the starter. If the starter is in an overcurrent condition, the
LED will blink every second. Whenever the motor is in an
overcurrent condition and turns full ON indicating a tripped
condition, a RESET is required before the motor can be
restarted. If a ground current condition exists and the star-
ter has the catalog suffix Y7 (ground protection omitted),
the LED will blink twice every second, but no trip will occur.
The internal trip indicator is visible only with the enclosure
door open.
OVERLOAD SETTINGS
The cutout in the arc box cover that provides access to
the DIP switch is designed to accept a snap-in clear plastic
window. Insert the window after initial DIP switch settings
Fig. 2 Size 3 and 4 Outline and Mounting Dimensions (dimensions in inches)
have been made by engaging the hooks of one corner
and pushing on the opposite corner. To change a DIP
switch setting after the window has been installed, remove
the arc box cover by loosening the two captive cover
screws accessible through the nameplate.
Use the eight-position (8 pole) DIP switch to select the
method of reset (MANUAL or AUTOMATIC), the overload
protection Class (10, 20, 30, or NONE), and the trip current
rating appropriate for the motor full load current in amperes
(FLA). When a DIP switch handle is moved towards the
position number (marked 8 through 1, left to right), that
pole is closed (represented by 1). When a switch handle
is moved away from the position number, the pole is open
(represented by 0). See Figure 3.
Be sure that each DIP switch handle is moved to the
full ON (1) or full OFF (0) position.
