Risk of injury due to malfunction of valves with alternating current (AC).
Sticking core causes coil to overheat, resulting in a
malfunction.
• Monitor process to ensure function is in perfect working order!
Risk of short-circuit/escape of media through leaking
screw joints.
• Ensure seals are seated correctly!
• Carefully screw together coil and device socket or valve
and connection plate!
General Hazardous Situations.
To prevent injuries:
• Ensure that the system cannot be activated unintentionally.
• Installation and maintenance work may only be carried

Operating duration
Unless otherwise indicated on the type label, the solenoid
system is suitable for continuous operation.
Important information for functional reliability during
continuous operation!
For long switch-on or switch-off times a minimum
actuation of 1-2 switching operations per day is
recommended.
Service life
High switching frequency and high pressures reduce the
service life.

8.2. Installation of coil
WARNING!
Escaping medium!
When a sticking nut is loosened, medium may escape.
• Do not tighten sticking nut any further.
Electric shock!
If the protective conductor contact between the coil and
housing is missing, there is danger of electrical shock!
• Check protective conductor contact after installing the
coil.
Overheating, risk of fire!
Connection of the coil without pre-assembled valve will
result in overheating and destroy the coil.
• Connect the coil with pre-assembled valve only.
Danger due to electrical shock if coil incorrectly installed!
• During installation ensure that the coil is seated firmly
on the step of the core guide tube so that the protective
conductor connection of the coil has a connection to
the valve housing.
Procedure:
→ Connect coil housing to the core guide pipe.
→ Screw on coil with nut. Observe torque.
→ Check protective conductor.
