I
Alarm display
G
If an alarm occurs while the system is operating, the alarm display LED on the unit display will blink at 1-second
intervals (0.5 seconds ON, 0.5 seconds OFF) for the number of times that corresponds to the alarm code.
G
When facing the control PCB, the LED on the LD005 indicates the first digit, and the LED on the LD006
indicates the second digit.
For example, when alarm F10 occurs, the alarm code is 6A. Therefore, the LED for the first digit blinks 6 times,
then the LED for the second digit blinks 10 times.
