Motor Thermistor
Motor thermistors can be connected directly to the CSXi terminals B4, B5. If motor thermistors are not
used, there must be a link between B4, B5 (the CSXi is supplied with a link fitted).
3.4 Outputs
Main Contactor Output
The Main Contactor output (terminals 13, 14) closes as soon as the soft starter receives a start command
and remains closed while the soft starter is controlling the motor (until the motor starts a coast to stop, or
until the end of a soft stop). The Main Contactor output will also open if the soft starter trips.
The Main Contactor output can be used to directly control a main contactor coil.
Programmable Output
The programmable output relay (terminals 23, 24) can be used to signal either trip or run status. This
relay is normally open.
Trip:
The relay closes when the CSXi trips. The relay can be used to operate the shunt-trip mechanism of an
upstream circuit breaker (in order to isolate the motor branch circuit), or to signal the trip to an automation
system or externally. The relay will open when the trip is reset.
Run:
The relay operates when the soft start is complete, the bypass relays are closed and full voltage is being
applied to the motor. The relay can be used to operate a contactor for power factor correction
capacitors, or to signal soft starter run status to an automation system.

Motor Trip Class
Select the trip class for motor overload
protection.
The trip class reflects the maximum time (in
seconds) that the motor can run at locked rotor
current. The Motor Trip Class setting assumes a
locked rotor current of 600%.
Setting the motor trip class to "Off" disables
motor overload protection.
Motor Full Load Current
Configure the soft starter to match the motor's
full load current (FLC).
Configure according to the motor's nameplate
current. Divide the motor's FLC by the soft
starter's maximum current rating (on the soft
starter's nameplate label).

Auxiliary Relay Function
Select the function of the soft starter's
programmable output (terminals 23, 24).
When set to "Run", the relay will operate when
the soft start is complete. When set to "Trip",
the relay will operate when the soft starter trips.

Phase Sequence Protection
Configure the soft starter's phase sequence
protection.
Select the allowable phase sequences. A setting
of "Fwd" allows forward sequence (positive
rotation) only and a setting of "Any" defeats the
protection.
NOTE
Auxiliary relay function and phase rotation are configured using a shared switch. Set the
auxiliary relay function as required, then set phase rotation protection.

5 Troubleshooting
5.1 LEDs
5.2 Trip Codes
The Ready LED will flash a different number of times to indicate the cause of the trip.
5.3 Protections
The CSXi includes the following types of protection for the motor and starter:
Excess Start Time Protection
The CSXi will trip on excess start time if the motor does not successfully start within the time selected in
the Excess Start Time setting. This may indicate that the load has stalled.
If the soft starter frequently trips on excess start time:
check that the Current Limit setting is high enough for the application
check that the Excess Start Time setting is long enough for the application
check that the load has not stalled or increased since the soft starter was installed
Motor Overload Protection
The CSXi will trip on motor overload if it calculates that the motor has been running above its operating
range for longer than the time selected in the Motor Trip Class setting. Motor Trip Class should be set to
match the motor's locked rotor time. If this information is not available from the motor datasheet, use the
default setting (Motor Trip Class = 10). Using a higher setting can damage the motor.
710-02408-00H CSXi Page 7
TROUBLESHOOTING
Phase Imbalance Protection
The CSXi will trip on phase imbalance if the highest and lowest currents on the three phases vary by an
average of 30% for more than 3 seconds. Phase imbalance protection is not adjustable, and is only active
when the average motor current is 50% or more of the programmed motor FLC.
If the soft starter frequently trips on phase imbalance:
check that there is no imbalance on the mains voltage (on the input side of the soft starter)
insulation test the motor
move all input cables over one position (move L1 cable to L2, move L2 cable to L3, move L3 cable
Supply Frequency Protection
The soft starter will trip on supply frequency if the frequency rises above 72 Hz or falls below 40 Hz for
more than five seconds while the soft starter is running. These trip points are not adjustable.
In pre-start, starting and stopping modes the high and low frequency limits both apply with no time delay.
A supply frequency trip will also occur if:
all three input phases are lost while the soft starter is running
all three input phases fall below 120 VAC at start or while the soft starter is running
the line contactor opens while running
Bypass Overload Protection
Bypass overload protection protects the soft starter from severe operating overloads while running. The
protection is not adjustable and has two components:
The soft starter will trip if it detects overcurrent at 600% of the programmed motor full load
The soft starter models the temperature of the internal bypass relays and will trip if the
If the trip occurs frequently, this indicates that the soft starter has not been selected correctly for the
application.

temperature exceeds the safe operating level.
Trips can be cleared by pressing the Reset button on the soft starter, sending a Reset command from the
serial communications network, or by switching the control inputs.
To clear a trip via the control inputs, the soft starter requires a closed to open transition on the stop input
(02).
In three-wire control, use the external stop button to momentarily open the stop input (open
A1-02).
In two-wire control, if the soft starter tripped with a start signal present, remove the start signal
(open A1 to 01, 02).
