Trip Codes

The Ready LED will flash a different number of times to indicate the cause of the trip.
Ready LED Description
Power Circuit: Check mains supply (L1, L2, L3), motor circuit (T1, T2, T3), soft starter SCRs
x 1
and bypass relays.
Excess Start Time: Check load, increase Current Limit or adjust Excess Start Time setting.
x 2
Motor Overload: Allow motor to cool, reset soft starter and restart.
x 3
The soft starter cannot be reset until the motor has cooled.
Motor Thermistor: Check motor ventilation and thermistor connection B4, B5. Allow motor
x 4
to cool.
Phase Imbalance: Check for mains supply or line current imbalance (L1, L2, L3).
x 5
Supply Frequency: Check mains voltage is available and supply frequency is in range.
x 6
Phase Rotation: Check for correct phase rotation.
x 7
Network Communication Failure (between interface and network): Check network
x 8
connections, settings and configuration.
Starter Communication Failure (between starter and interface): Remove and refit accessory
x 9
interface.
Bypass Overload: Starter rating may be too low for the application.

Protections
i
The CSX
includes the following types of protection for the motor and starter:
Excess Start Time Protection
The CSX
i
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
i
The CSX
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.
NOTE
Motor overload protection does not protect the soft starter, and does not protect the motor
from short circuit.
