. LEDs Indicators – single split only
If any fault exists in the system, it will be shown according to tIf no fault exists in the system, no
fault code will be displayed during normal operation mode, and the status led will be on while the
compressor is enable.he following coding method.
Two LEDs display the system diagnostics on real time as follows:
STATUS LED is blinking 5 times in 5 seconds, and shut off for the next 5 seconds.
FAULT LED will blink during the same 5 seconds according to the following table:

1. Whenever this table is updated, the installation test procedure, and the alarm output function
should be updated.
2. Only one code is shown.
3. Order of priority is 1-32. Diagnostics is continuously ON as long as power is on.
4. Heat Sink Over Heating Protection, Compressor Over Heating Protection, and System Over
Power Protection are declared only whenever in ‘Stop-Compressor’ status.
5. All faults, except the thermistor faults, will remain at least 10 seconds. This rule comes to
serve the monitoring utilities, in a case the fault is released quickly it will be still shown under
the monitoring utilities.
