Fault messages
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.
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 displayed
if the Sunny Boy detected a problem with the frequency of the
utility grid. The message would clear automatically once the
condition was corrected. Disturbances are typically caused
by a measured value exceeding a predetermined limit.
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 GFDI fuse was open or cleared. Typically, Warning
messages indicate a system condition 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 prevent the inverter from restarting until the
condition is cleared.
