Pneumatic Connection; Electrical Connection - Burkert 0470 Manuel D'utilisation

Risk of injury from unintentional activation of the system and
uncontrolled restart!
▶ Secure system against unintentional activation.
▶ Following assembly, ensure a controlled restart.
7.2 Type 5470, turning the solenoid coil
The valves are supplied fully assembled. If the solenoid coil in the
pilot valve is in an unfavorable position for installation, the coil can be
turned 180°.
WARNING!
Risk of electrical shock if the coil is incorrectly fitted!
▶ During installation, make sure that the coil is firmly seated on the
valve body so that the protective conductor connection of the coil is
in contact with the valve housing.
▶ Check the function of the protective conductor (for test values, see
"Tab. 1", page 11).
→
Loosen M2 screws and pull coil away from the valve body.
→
Turn coil, attach to valve body, and screw on with M2 screws,
tightening alternately step by step. While doing so, observe the
tightening torque:

7.5 Electrical connection

WARNING
Risk of injury due to electrical shock!
▶ Before reaching into the system, switch off the electrical power
supply and secure to prevent reactivation!
▶ Observe applicable accident prevention and safety regulations for
electrical equipment!
▶ When screwing the coil onto the device socket, make sure the
seal is correctly seated.
If the protective conductor contact between the coil and housing is
missing, there is a danger of electric shock!
▶ Always connect protective conductor.
▶ Check electrical continuity between coil and housing.

7.4 Pneumatic connection

WARNING!
Risk of injury from greatly accelerated device parts and uncon-
nected whiplashing compressed air hoses!
▶ Before pressurizing the valve, check that all screw connections and
screw joints are tight and secure.
Installation position: any, preferably with solenoid system face up.
Before connecting:
→
Check whether hose lines are dirty and clean.
→
If required, install a dirt filter upstream of the valve inlet (≤ 5 µm).
Pneumatic connection:
NOTE!
Risk of breakage!
▶ Do not use coil as a lever arm.
▶ Do not use a cylinder wrench to tighten screws.
→
Hold the device by hand on the housing and connect to the hose
line. Do not exceed the standard screw-in depth.
→
Seal with PTFE tape or elastomer seal.
