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 valve and connection lines together.
General hazardous situations.
To prevent injury, ensure that:
▶ Do not make any internal or external changes. Ensure that the system
cannot be activated unintentionally.
▶ Installation and repair work may be carried out by authorized techni-
cians only and with the appropriate tools.
▶ After an interruption in the power supply or pneumatic supply, ensure
that the process is restarted in a defined or controlled manner.
▶ Do not put any loads on the body.
3 BASIC SAFETY INSTRUCTIONS
These safety instructions do not make allowance for any contingencies
and events which may arise during installation, operation and maintenance.
Danger – high pressure!
▶ Before loosening the lines and valves, turn off the pressure and
vent the lines.
Risk of electric shock!
▶ Before reaching into the system, switch off the power supply and
secure to prevent reactivation!
▶ Observe applicable accident prevention and safety regulations for
electrical equipment!
Risk of burns/Risk of fire if used continuously through hot device
surface!
▶ Keep the device away from highly flammable substances and media
and do not touch with bare hands.
