11 Troubleshooting
11.1 Protection Responses
When a protection condition is detected, the ASA 4.0 Advanced will write this to the event log and may also trip or issue a warning. The
soft starter's response depends on the Protection Action setting (parameter group 6).
Some protection responses cannot be adjusted by the user. These trips are usually caused by external events (such as phase loss) or
by a fault within the soft starter. These trips do not have associated parameters and cannot be set to Warn or Log.
If the ASA 4.0 Advanced trips you will need to identify and clear the condition that triggered the trip, then reset the soft starter before
restarting. To reset the starter, press the
RESET
button on the keypad or activate the Reset remote input.
If the ASA 4.0 Advanced has issued a warning, the soft starter will reset itself once the cause of the warning has been resolved.
11.2 Trip Messages
Display Possible cause/Suggested solution
2 Phase - Damaged
SCR
This message is displayed if the soft starter tripped on “ Lx-Tx shorted” during the pre-start checks and
PowerThrough is enabled. It indicates that the starter now operates in PowerThrough mode (2-phase
control only).
Check for either a shorted SCR or a short within the bypass contactor.
Related parameters: 6S
Battery/clock
A verification error has occurred on the real time clock, or the backup battery voltage is low. If the
battery is low and the power is off, date/time settings will be lost. The ASA 4.0 Advanced will continue
to soft start and soft stop correctly. Reprogram the date and time.
The battery is not removable. In order to replace the battery, the main control PCB must be replaced.
Related parameters: 6T
Bypass overload
This trip is not adjustable.
Bypass overload protection protects the soft starter from severe operating overloads while running. The
soft starter will trip if it detects overcurrent at 600% of the contactor rating.
Related parameters: None
Current imbalance
Current imbalance can be caused by problems with the motor, the environment or the installation, such
as:
•
An imbalance in the incoming mains voltage
•
A problem with the motor windings
•
A light load on the motor
•
A phase loss on input terminals L1, L2 or L3 during Run mode
•
An SCR that has failed open circuit. A failed SCR can only be definitely diagnosed by replacing
the SCR and checking the starter's performance.
Related parameters: 5A, 5B, 6C
Current Read Err Lx
Where 'X' is 1, 2 or 3.
Internal fault (PCB fault). The output from the CT circuit is not close enough to zero when the SCRs are
turned off. Contact your local supplier for advice.
Related parameters: None
Depth Sensor
The smart card has detected a fault with the depth sensor.
Related parameters: 30L, 36C
EEPROM fail
An error occurred loading data from the EEPROM to RAM when the keypad powered up. If the
problem persists, contact your local distributor.
Related parameters: None
Excess start time
Excess start time trip can occur in the following conditions:
•
parameter 1B Motor Full Load Current is not appropriate for the motor
•
parameter 2D Current Limit has been set too low
•
parameter 2B Start Ramp Time has been set greater than the setting for 5O Excess Start Time
•
parameter 2B Start Ramp Time is set too short for a high inertia load when using Adaptive Control
Related parameters: 1B, 2B, 2D, 3D, 3F
Firing Fail Px
Where 'X' is phase 1, 2 or 3.
The SCR did not fire as expected. The SCR may be faulty or there may be an internal wiring fault.
Related parameters: None
FLC too high
If the soft starter is connected to the motor using inside delta configuration, the soft starter may not be
correctly detecting the connection. Contact your local supplier for advice.
Related parameters: None
Flow Sensor
The smart card has detected a fault with the flow sensor.
Related parameters: 30E, 36B
Flow Switch
The flow switch sensor (smart card terminals C23, C24) has closed.
Related parameters: 30E, 36H
