10-3. Error Mode Detected by LED on Outdoor P.C. Board
RAV-SM800AT-E
<SW800: LED display in bit 1, bit 2, bit 3, bit 4 OFF>
• When multiple errors are detected, the latest error is displayed.
• While LED displays (go on), there is the main cause of error in control at CDB side and it stops abnormally.
• While LED displays (flash), there is the main cause of error in control at IPDU side and it stops abnormally.
• For an error in case thermo operation, the communication is interrupted on the serial circuit. If continuing the
case thermo operation, serial sending to the indoor unit is interrupted and a serial communication error is
output.
