3) For the use at low temperatures, see Project planning
information on page 32.
4) Due to the arising surface temperatures of the solenoid coils,
the standards ISO 13732-1 and ISO 4413 are to be observed.
The specified surface temperature in AC solenoids is valid for
fault-free operation. In the error case (e.g. blocking of the control
spool), the surface temperature may increase above 180 °C.
Thus, the system must be checked for possible dangers
considering the ignition temperature of the hydraulic fluid used.
As protection, circuit breakers (see table page 4 … 7)
must be used, unless the creation of an ignitable atmosphere
can be excluded in a different way. Thus, the surface temperature
can – in the error case – be limited to maximally 220 °C.
You have to use connection cables that have been approved of for
a working temperature of more than 90 °C (individual connection)
and/or 105 °C (central connection). Contact between the
connection cable and the coil surfaces must be prevented.

Technical data
Notice:
▶ Any simultaneous actuation of 2 solenoids of one valve must be
ruled out.
▶ Due to possible overload of the board, valves with central
connection must not be operated with twice the voltage.
▶ If the standard environmental conditions according to
EN 60204-1 cannot be provided, the valve must be especially
protected!
▶ Energy saving
If directional valves with a nominal voltage of 24 V are used,
a switching amplifier will reduce the continuous current
considerably.
After a defined power supply time and the connected hydraulic
switching of the valve, the system switches to pulse width
modulation and the power is considerably reduced. This leads to
a holding power under the power of a valve with 24 V supply
voltage (see data sheet 30362).
▶ Fast switch-on
For accelerated switching on the solenoid side, valves with
individual connection and a nominal voltage of 12 V or 24 V can
be controlled with two times the voltage for a maximum of
100 ms (pulse width modulation see data sheet 30362). In this
connection, the maximum admissible switching frequency is
reduced to 3 1/s.
▶ Dampened switching
With valves of version "A12", damping of the switch-on and
switch-off process is possible (smoothly switching). In this way,
switching shocks in the system are considerably reduced.

Type VT-SSBA1-PWM-1X/V002/5 For energy reduction (energy savings of approx. 40%) 4) R901290194
2) Only with symbols C, D, E, E67, J, J2 and Y; not for version "D" Use with PWM connector (data sheet 30362):
with reinforced compression spring ▶ Depending on the control spool, increasing the performance
3) Only for version "G12" and "K4/K4K" limit is possible.
4) Only for version "G24" and "K4/K4K" ▶ With version "G24" (energy saving), the coil temperature is
reduced by ≥ 30 °C for 100% duty cycle.
