The conducted or radiated disturbances generated by
solid state relays depend on the wiring and load
configuration.
The test method recommended by the European standards
and concerning electromagnetic compatibility leading to
results far from reality, we decided to advise our customer
in order to adapt their filtering scheme to their application.
Please refer to the SVTA – SWTA installation manual.

DIAGNOSTIC
Phase presence = OK ; Phase voltage = OK ; Phase frequency = OK

DIAGNOSTIC
Phase presence = OK ; Phase voltage = OK ; Phase frequency = OK
LEDs blinking sequence indicates mains phase rotation is reverse

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.

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.
