5.1 OPERATING FAULT DIAGNOSTICS
The control box has a self-diagnostic system, which easily allows identifying the operating faults ( RED LED
signal).
To use this function, wait at least ten seconds from the safety lock out, and then press the reset button for a
minimum of 3 seconds.
After releasing the button, the RED LED starts flashing as shown in the diagram below.
The LED gives of a blink code every 3 seconds.
The blink codes give the information about the possible faults, as follows:
