Danger zones
Please observe the following notes:
Fig.5
•
In the event of malfunctions, shut down the valve (disconnect from the power
and air supply) and secure it against being used.
•
Never reach into the lantern (9) or the valve housing (401) when the valve is
switching. Fingers can be crushed or cut off.
•
On a spring-closing valve, there is a risk of injury upon releasing the clamp
connection (43/46) as the released spring pretension will suddenly lift the
actuator (A). Therefore, release the spring tension before detaching the clamp
connection (43) by supplying the actuator (A) with compressed air.
•
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.
•
The housing sockets have very sharp edges. When transporting and
assembling the valve be sure to wear suitable protective gloves.
