2.1 Definition of term

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

solenoid valve Type 0287.

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 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.

4 SYSTEM DESCRIPTION

4.1 General description

The solenoid valve modules

(SV modules) are stacked

in blocks with the aid of pull

rods and connection pieces.

The valve has the following

functions:

• Distributor (1 input, 2-10

outputs)

• Collector (1 output, 2-10

inputs)

• mixed (2-10 SV modules)

Collector

Distributor

The SV modules with collector function have a non-return valve con-

nected upstream as standard. As a result, the minimum pressure

difference increases to 1 bar.
