●
In the
event of malfunctions, shut down the valve (disconnect from the power and
air supply) and secure it against being used.
●
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 qualied electrician to carry out any work on the electrical power sup-
ply.
●
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.
●
Never reach into the lantern (9), the valve housings (G) or into the sockets of the
valve housings (G.1) 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 connec-
tion (43) as the released spring pretension will suddenly lift the actuator (A). There-
fore, release the spring tension before detaching the clamp connection (43/46) by
supplying the actuator (A) with compressed air.
●
The housing sockets (401) have very sharp edges. When transporting and installing
the valve be sure to wear suitable protective gloves.
Dangerous situations can be avoided by safety-conscious and proactive behaviour of
the personnel and by wearing personal pr
otective equipment.
