34/48 Operation

Observe the operating instructions of the device and/or system into which the
valve is installed.
▶
Before the actual operation, switch the valve several times with reduced
pressure (50% operating pressure). This will press out any remaining air
from the valve. Thus, mechanical damage being caused by inadmissibly high
acceleration of the fluid and the valve control spool is avoided and the life cycle
of the valve is extended.
▶
Ensure that no hydraulic fluid leaks at the valve and the connections during
operation.
▶
Check whether there is an internal leakage. The check must be carried out
according to the possibilities present at the hydraulic system.
Internal leakage can be valve-specific but does not necessarily affect the
functionality of the valve.
9 Operation
9.1 General information
WARNING
Explosion hazard by the ignition of dust accumulations!
If the maximum dust layer thickness of > 5 mm is exceeded, there is an explosion
hazard!
▶
Make sure that the maximum dust layer thickness is not exceeded.
▶
Regularly remove dust accumulations.
Explosion hazard caused by overheating!
Loss of explosion protection due to overheating!
▶
In case of bank assembly, only one solenoid of all valves may be energized at
a time.
CAUTION
Loud noise!
An unfavorable arrangement of valves results in resonance or fluid noises, such as
whistling. In continuous operation, these noises may cause hearing damage in
persons or damage at the valves.
▶
In this case, contact a service engineer.
