delta wiring:
 Resistive (Bulbs, UV and IR lamps, ovens, …),
 Inductive (inductors, transformers, …),
 Motor (motorfan speed control (60 to 100% from the nominal speed),
 Rectified (power supplies, …).
 Small housing, easy and ready to use.
 Large mains frequency and voltage range.
 Fully optoisolated full cycle three phase phase angle controller (balanced currents, less
harmonics, …)
 Dynamic control voltage range according to the power factor of the load.
 Softstart and softstop functions (increase lifetime expectancy of the load).
 Adjustable filter regarding fast input voltage changes (ramps).

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.

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

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.
