9.4 Operating the optional manual override at the directional valve
Valves of type DBAW, i.e. valves with directional valve, are provided with a manual
override which is concealed by a protective cap. Using this manual override, the
switching function of the directional valve can also be triggered if the solenoid is not
energized.
The manual override is only intended for manual operation.
The manual override is located at the side of the solenoid coil facing away from the
solenoid coil.
Incorrect operation of the manual override!
There is the risk of damaging the valve and/or incorrect operation may result in
dangerous movements of the connected actuators.
▶
Only operate the manual override if it is ensured that this will not trigger any
dangerous working movement of the connected actuator.
▶
Do not use sharp-edged tools to operate the manual override. There is the
danger of damaging sealing surfaces at the solenoid.
The manual override is only intended for short-time manual operation and must not
be brought into a certain spool position for a longer period or permanently by means
of mechanical devices.
The manual override is not suitable for frequently recurring manual operations!
1.
Remove the protective cap.
2.
Use a rounded tool with a maximum diameter of 5 mm to push the manual
override in the direction of the valve housing.
3.
Re-attach the protective cap.
