Troubleshooting and corrective measures
Error messages are displayed in red in the display footer.
(
Err
) As soon as a fault is resolved this message disappears
automatically. I.e. error messages do not have to be acknowledged.
If the key
➔
is pressed in display page 4, a help text appears for
each pending fault.
Errors 1-9 can be detected by the EFR4001IP itself; the numbering is used in the fault memory (only in the
display) and in the logging:
No Fault
Cause
Corrective measure
1
Limit error
Limit ON must be less than limit OFF
Exchange limits
2
Limit difference error
Difference between limit value ON and
limit value OFF is less than the set
value. Output relay would switch
between on and off.
Adjust limits or load value
3
AD converter error
Internal AD converter error
Reset, interrupt supply
voltage Us for > 5s*
4
Adjustment values error
Adjustment values are out of the
tolerance.
5
Parameter error
Parameter value out of range.
6
Internal memory error
Error in internal memory
7
Current transformer error
Current transformer connections
reversed, current transformer
incorrectly connected.
+
: Draw (import = purchase)
-
: Feed-in (export),
turn current transformer,
replace S1(k) and S2(l) on
the EFR4001IP (switch off
the primary circuit first!)
8
Vault load value (only in Pr 3)
At least 2 relays have the same load
value.
In Pr3, there must be no 2
equal loads, if necessary,
slightly increase a load
value.
9
Setting error regulation
Analogue outputs U and I cannot
control to the same measured value /
phase.
Deactivate a regulation or
regulate it to another phase.
