1)	Special voltages available upon request
2)	The switching times were determined at a hydraulic fluid temperature of 40 °C and a viscosity of 46 mm2/s. Deviating hydraulic fluid temperatures can result in different switching times. Switching times change dependent on operating time and application conditions.
3)	Due to the surface temperatures of the solenoid coils, the standards ISO 13732-1 and EN 982 need to be adhered to!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 [356 °F]. Thus, the system must be checked for possible dangers considering the flash point (see table Hydraulic fluids).As fuse protection, circuit breakers (see table Circuit breakers) 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 [428 °F].Within a time interval of 0.6 s, the tripping current must be 8 to 10 times the nominal power supply (tripping characteristics “K”).The required non-tripping current of the fuse must not fall below the value I1 (see table Circuit breakers with tripping characteristics “K”). The maximum tripping current of the fuse must not exceed the value I2 (see table Circuit breakers with tripping characteristics “K”).The temperature dependence of the tripping behavior of the circuit breakers has to be observed according to the manufacturer's specifications.

Notices!

Actuation of the manual override is only possible up to a tank pressure of approx. 50 bar. Avoid damage to the bore of the manual override! (Special tool for the operation, separate order, material no. R900024943). When the manual override is blocked, the actuation of the solenoid must be prevented! The simultaneous actuation of the solenoids must be prevented!

Notice!

AC solenoids can be used for 2 or 3 mains; e.g. solenoid type W110 for: 110 V, 50 Hz; 110 V, 60 Hz; 120 V, 60 Hz
