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.

LOAD POSSIBLE CAUSE SOLUTION WHATEVER IS THE VOLTAGE VALUE AT THE ANALOG INPUT OFF Mains is missing or it is connected on the motor side (2T1, 4T2, 6T3) of the device, instead of the mains side (1L1, 3L2, 5L3) Check the power side wiring OFF Mains voltage too low Check phase to phase voltage between 3L2 and 5L3 OFF OFF OFF OFF OFF OFF 1 or 2 phase(s) missing, Mains frequency out of range, Too many disturbances Microcontroller malfunction or too many problems at the same time Load connection missing, Shorted thyristor (s) A problem on the main occurred (e.g. phase missing) and now it is OK but analog input voltage is present A problem on the load occurred (e.g. temporary disconnection) and now it is OK but analog input voltage is present Check the phases Disconnect the device from the mains for a while and check the wiring Check load connections and measure the power element resistance (should be several 100kOhms) Remove the analog input voltage for a while Remove the analog input voltage for a while Factory diagnostic Consult us ANALOG INPUT VOLTAGE ABOVE THE MINIMUM CONTROL VOLTAGE THRESHOLD OFF Power elements can not turn on Check connection between 5 and 6 of the control terminal block. 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
