3)
The switching times have been determined at a hydraulic
fluid temperature of 40 °C and 46 cSt. Deviating hydraulic
fluid temperatures can result in different switching times!
Switching times change depending on operating time and
application conditions.
4)
Due to the temperatures occurring at the surfaces of the
solenoid coils, the standards ISO 13732-1 and EN 982
need to be adhered to!
The specified surface temperature in AC voltage solenoids
is valid for the faultless operation. In case of failure (e. g.
blocking of the control spool), the surface temperature
may rise to above 180 °C. Considering the flash point (see
page 8), the system must therefore be checked for pos-
sible risks.
As fuse protection, circuit breakers (see table on the
right) must be used unless the creation of an ignitable
atmosphere can be excluded in a different way. Thus, the
surface temperature can - in case of failure - be limited to
maximally 220 °C. The tripping current must lie within a
time interval of 0.6 s with 8 to 10 times the nominal power
consumption. (Tripping characteristics "K").
The necessary non-tripping current of the fuse must not fall
below the value I
(see table page 16). The maximum
1
tripping current of the fuse must not exceed the value I
(see table page 16).
The temperature dependence of the tripping behavior of
the circuit breakers has to be considered according to the
manufacturer's specifications.
Notices!
– Actuation of the manual override is only possible up to a
tank pressure of ca. 50 bar. Avoid damage to the bore for
the manual override! (Special tool for the operation, sepa-
rate order, Material no. R900024943). When the manual
override is blocked, the operation of the solenoid must be
ruled out!
– The simultaneous operation of the solenoids must be
ruled out!
