4 - FAULTS - DIAGNOSTICS
4.1 - Operating faults
• An access code has just been entered
which does not correspond to the one
which has already been memorized.
- Re-enter the access code.
• A parameter has just been modified but it
has not been memorized before exiting the
field.
- Press to memorize the modifica-
tion.
- If the modification does not need to be
memorized, use the key.
• A user wishes to transfer parameters
from the console to the STV 2313, but
nothing has been memorized in the
console, or the contents of the parameters
transferred to the console are not
compatible with the STV 2313 to which it is
connected. Use one of the four arrow keys
to return to the preceding menu.
4.2 - "FAULT" messages
When a fault occurs, the STV 2313
displays the "FAULT" message on the

• No voltage on the L1 - L2 - L3 terminals.
• Start time is greater than the "Max time"
set in menu 11 (protection settings).
- Load conditions are more severe than
those used as a reference for the settings
--> Revise the "Max time"
- Defective motor (insufficient torque).
- Incorrect motor connection.
• Start conditions greater than the thermal
capacity of the STV 2313.
- Start current is too high,
- Idle period between 2 starts is too short,
- Start time is too long,
- Capacity of equipment is insufficient.
• Upstream or downstream phase failure
on the STV 2313 :
- Open power fuses,
- Motor cable cut or connectors loose.
• Mains supply loss and restart after short
