The following is a list of errors that can occur during the power-up phase of operation.
These errors may only be cleared by switching the Indoor Unit off and then on again.
The list also describes the possible faults and corrective actions to solve each error.
Error Possible Faults and Corrective Actions
FLASH The Application FLASH memory test failed. Only a faulty Application Flash
device can cause this fault and the Application Flash device will have to
be replaced.
DRAM Error The DRAM test failed. Only a faulty DRAM device can cause this fault
and the DRAM will have to be replaced.
SRAM Error The battery-backed up SRAM test failed. Only a faulty SRAM device or
battery can cause this fault and the Battery and/or SRAM will have to be
replaced.
Watchdog
Reset
Software error. Please contact the supplier. Processor triggered a
watchdog restart because watchdog is no longer being toggled by the
application. Either the application has become too overloaded or this is a
software or design fault.
Hard Reset A hardware reset was performed. This is an indication of the last reason
for a reset and does not constitute a fault condition.
Unknown Reset Another reset detected by the Indoor Unit’s microprocessor (other than
Watchdog and Hard Reset) was performed. This is an indication of the
last reason for a reset and does not constitute a fault condition.
Line Interface
Error
The line interface transceiver is not responding as expected and is most
likely faulty. The transceiver is programmed for operation and then
checked to see that the values programmed are valid (read correctly).
FPGA The FPGA register interface is not responding correctly and is most likely
faulty. The FPGA is programmed for operation and then checked to see
that the values programmed are valid (read correctly).
Real Time Clock The Real Time Clock (RTC) is not responding correctly and is most likely
faulty. The RTC is programmed for operation and then checked to see
that the values programmed are valid (read correctly).
Use the Clear button to clear alarm indicators.
