Special application conditions for a safe application

Maximum ambient temperature:
In case of bank assembly, as long as only one solenoid is energized at a time, and in case of individual assembly: +70 °C
In case of bank assembly, if more than one solenoids are energized simultaneously: +60 °C

The maximum temperature of the surface of the valve jacket is 120 °C. This has to be considered when selecting the connection cable and/or contact of the connection cable with the surface of the jacket is to be prevented.

Notice: The switching times were determined at a hydraulic fluid temperature of 40 °C and 46 mm²/s. Deviating hydraulic fluid temperatures can result in different switching times. Switching times change dependent on operating time and application conditions.

Notice

The switching power limits were established while the solenoids were at operating temperature, at 10 % undervoltage and without tank preloading.

Please observe the general notes (see chapter "Information").
