2.9
Danger zones
Please observe the following notes:
•
In the event of malfunctions, shut down the valve (disconnect from the power
and air supply) and secure it against being used.
•
When the valve is switching, never reach into the valve housing (391), the
motor stool (9) or into the valve inlet X (on pneumatic actuators). Fingers can
be crushed or cut off.
•
When releasing the grooved cap nut (252) of the non-actuated valve (spring-
to-close version) there is a risk of the bellows and the round thread of the
grooved cap nut being damaged. Before releasing the grooved cap nut (252)
therefore relieve the spring tension by pressurizing the actuator with
compressed air. The valve is opened.
•
The housing sockets have very sharp edges. When transporting and
assembling the valve therefore be sure to wear suitable protective gloves.
•
Before starting any service, maintenance or repair work, disconnect the valve
from the power supply and secure it against inadvertently being switched
back on again.
•
Only allow a qualified electrician to carry out any work on the electrical power
supply.
•
Check the electrical equipment of the valve at regular intervals. Immediately
remedy loose connections and molten cables.
•
If work on live parts cannot be avoided, call in a second person, who can
operate the main switch in case of an emergency.
