Danger zone at the valve
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.
•
Never reach into the lantern (9) or the valve housing (401) when the valve is
switching. Fingers can be crushed or cut off.
•
Do not reach into the feedback signal (E) when the valve is switching. Limbs
can be crushed or cut off.
•
On a spring-closing valve there is danger of injury when the clamp
connections (43, 44.46) are opened, as the released spring pretension will
suddenly lift the actuator. Therefore, release the spring tension before
detaching the clamp connections (43, 44, 46) by supplying the actuator (A)
with compressed air.
•
Before starting any maintenance, servicing 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.
