LOAD COMMENTS ANALOG INPUT VOLTAGE BELOW THE MINIMUM CONTROL VOLTAGE THRESHOLD OFF DIAGNOSTIC Phase presence = OK ; Phase voltage = OK ; Phase frequency = OK LEDs blinking sequence indicates mains phase rotation is direct Load connected Analog input voltage below the minimum control voltage threshold (0.3V (010V) ; 4mA (4-20mA) ; 0.15V (0-5V / potentiometer)) OFF DIAGNOSTIC Phase presence = OK ; Phase voltage = OK ; Phase frequency = OK LEDs blinking sequence indicates mains phase rotation is reverse Load connected Analog input voltage below the minimum control voltage threshold (0.3V (010V) ; 4mA (4-20mA) ; 0.15V (0-5V / potentiometer)) ANALOG INPUT VOLTAGE ABOVE THE MINIMUM CONTROL VOLTAGE THRESHOLD Indicates the voltage at the analog input or the voltage ramp set by the user (Time ramp (s)) is increasing. Indicates the voltage at the analog input exceeds the maximum full power threshold voltage (9.7V (0-10V);19.7mA (4-20mA);4.9V (0-5V / potentiometer)) Indicates the voltage at the analog input or the voltage ramp set by the user (soft-stop) is decreasing.

Check the load current is above the minimum specified ON 1 or 2 phase(s) missing, Mains frequency out of range, Too many disturbances Check the phases LEGENDE OFF GREEN RED BLINKING OFF/GREEN BLINKING OFF/RED 123- IMPORTANT INFORMATION CONCERNING THE DIAGNOSTIC The device makes a complete diagnostic (mains, load and itself) as soon as the mains voltage is sufficient The device checks only the presence of phases when the analog input voltage is above the minimum control threshold, during the ramps (softstart and softstop) and when it is full on (the power elements are tested only when analog control voltage is below the minimum control voltage threshold). The control overrides the diagnostic. If a problem occurs during the control period, the device will try to go on driving the load according the analog input voltage. If the problem goes on, it will be if possible indicated to the user according the diagnostic table. If a problem occurs during the softstopping period, the device will stop immediately in order to reach the off state diagnostic period. PRELIMINARY 22/01/04
