2.1 Definition of term

In these operating instructions, the term “device” always refers to the

Type 6213 EV / 6281 EV.

english

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 pipelines together.

To prevent injury, ensure that:

▶Do not make any external modifications to the housing of the

device. 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 fluidic supply, ensure

that the process is restarted in a defined or controlled manner.

▶Do not put any loads on the body.

▶The general rules of technology apply to application planning and

operation of the device.

3 BASIC SAFETY INSTRUCTIONS

These safety instructions do not make allowance for any

• contingencies and events which may arise during the installation,

operation and maintenance of the devices.

• local safety regulations - the operator is responsible for observing

these regulations, also with reference to the installation personnel.

Danger - high pressure.

▶Before loosening the pipes and valves, turn off the pressure and

vent the pipes.

Risk of electric shock.

▶Before reaching into the device or the equipment, 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 for a prolonged switch-on time

through hot device surface.

4.2 Application conditions

Ambient temperature: max. +55 °C

Operating duration: Unless otherwise indicated on the type label,

the solenoid system is suitable for con-

tinuous operation

Important information for functional reliability during continuous

operation.

If standstill for a long period at least 1-2 activations per day are

recommended.

Service life: High switching frequency and high pressures

reduce the service life

6.2 Installation of the coil

WARNING!

Electric shock.

▶Before reaching into the system, switch off the power supply and

secure to prevent reactivation.

▶During installation ensure that the coil is situated firmly on the body

cover so that the protective conductor connection of the coil is con-

nected to the valve body.

▶Check protective conductor contact after installing the coil.

english

Escaping medium.

When a sticking nut is loosened, medium may escape.

▶Do not tighten sticking nut any further.

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.

Procedure:

→Connect coil body to the core guide pipe.

→Screw on coil with nut. Observe torque.

NOTE!

Device will be damaged if the wrong tools are used.

Always use a wrench to tighten nut. If other tools are used (e.g. pliers),

the device may be damaged.

→Check protective conductor.

Observe
