Possible cause/Suggested solution
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, 6A
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: 6P, 12N
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 5G
Excess Start Time
setting
•
parameter 2B
Start Ramp Time
is set too short for a high
inertia load when using Adaptive Control
Related parameters: 1B, 2B, 2D, 3B, 3D
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: 6O, 12G
