Fault Messages
In case of a fault condition the LCD switches to “Fault“ mode and the backlight is
activated.
The upper display line indicates one of the three following failure types:
•
Disturbance
For example, this Disturbance message would be dis-
played if the SB3800U detected a problem with the fre-
quency of the utility grid. The message would clear
automatically once the condition was corrected. Distur-
bances are typically caused by a measured value ex-
ceeding a predetermined limit, the frequency of the AC
grid for example. The display will show the value of the
error (at:) as well as the present value for the particular
parameter (present:).
• Warning
For example, this Warning message would be displayed
if the inverter detected a problem with the array voltage.
Typically, Warning messages indicate a system condi-
tion that should be investigated. Warning conditions will
not preclude inverter operation.
•
Error
For example, this Error message would be displayed if
the inverter detected a problem with the internal ROM.
An Error condition will preclude the inverter from restart-
ing until the condition is cleared.
Note: Each fault message is displayed for 5 seconds. After
5 seconds, the LCD will once again scroll through its normal
operating screens. The fault condition will be included in the
series of screens until the condition is cleared.
