BASIC SAFETY INSTRUCTIONS

These safety instructions do not consider any contingencies
or incidents which occur during installation, operation andmaintenance.
The operator is responsible for observing the location-specificsafety regulations, also with reference to the personnel.

Risk of injury from high pressure.
▶ Before working on the system or device, switch off the pressureand vent or drain lines.
Risk of electric shock.
▶ Before reaching into the device, switch off the power supply
and secure to prevent reactivation!
▶ Observe applicable accident prevention and safety regulations
for electrical equipment!
Risk of burns and risk of fire if used during long-term operation
through hot device surface.
The solenoid coil can get very hot during long-term operation.
▶ Keep the device away from highly flammable substances andmedia and do not touch the device with bare hands.
Risk of explosion.
The solenoid coil and valve body form a closed system after installation. When used in potentially explosive atmosphere, there is a riskof explosion if the system is opened in the operating state.
▶ Do not remove or open the system during operation.

Risk of explosion due to electrostatic discharge.
In the event of a sudden discharge from electrostatically charged
devices or individuals, there is a risk of an explosion in the potentiallyexplosive atmosphere.
▶ Take suitable measures to ensure that no electrostatic discharges can build up in the potentially explosive atmosphere.
▶ Do not use the device in areas where there are powerful chargegenerating processes, mechanical reaming and cutting processes,
the spraying of electrons (e.g. in the vicinity of electrostatic coating
equipment) as well as pneumatically conveyed dust.
▶ Clean the device surface by gently wiping it with a damp or
antistatic cloth only.
To avoid the risk of explosion, the following must be observed for
operation in potentially explosive atmosphere:▶ Information on the temperature class, ambient temperature,degree of protection and voltage on the type label for potentiallyexplosive atmosphere.
▶ Installation, operation and maintenance may only be performedby qualified specialists.
▶ The applicable safety regulations (including national regulations) as well as general technical standards must be observed
during setup and operation.
▶ Repairs may only be performed by the manufacturer.
▶ The device must not be exposed to any mechanical and/or
thermal loads which exceed the limits specified in the operating
instructions.
▶ Before opening the terminal box, disconnect the power supply.

General information

General hazardous situations.
To prevent injury, ensure:▶ Secure system/equipment against unintentional activation.
▶ Observe the direction of flow during installation.
▶ After an interruption in the power supply or pneumatic supply,
ensure that the process is restarted in a defined or controlledmanner.
▶ Do not make any internal or external changes on the device
and do not subject it to mechanical stress.
▶ Installation, operation and maintenance may only be performed by qualified specialists.

AC10Specific conditions of use

5.2

Solenoid coil with cable outlet

The solenoid coil type AC10 is an electromagnetic valve actuator forvarious Bürkert valves. As a so-called top-mounted coil, it is separated
100 % from the valve. The valve is a closed system even if the coil isremoved. The solenoid coil consists of:• coil winding,• coil housing (made from epoxy),• electrical connection cable,• bridge rectifier.
Alternating current or direct current control is possible.
The solenoid coil type AC10 is available in a range of ratings distributed
across 2 frame sizes. The interface between the coil and valve is identical for both frame sizes.
The coil is placed over the core guide tube of the valve and attachedwith a nut. It is positively locked to prevent turning relative to the valve.
The electrical connection cable exits perpendicular to the coil axis.
The cable is permanently integrated in the coil. The union nut is notdesigned to be removed.
An electrical contact is made between the metal components of thevalve and the coil at the interface between the coil and the valve. All
metal components must be grounded via the protective conductor in
the connection cable.

5.3

Solenoid coil with terminal box

10

englishThe design of the solenoid coil is identical to the description under“5.2”, however a terminal box is also installed here (see “Fig. 2”).  A
connection set for additional potential equalisation is enclosed withthe terminal box; observe the specifications in chapter “8.2”.

SPECIFIC CONDITIONS OF USE

6.1

Avoiding build-up of electrostatic
chargeWARNING!

Risk of explosion due to electrostatic discharge.
In the event of a sudden discharge from electrostatically charged
devices or individuals, there is a risk of an explosion in the potentiallyexplosive atmosphere.
▶ Take suitable measures to ensure that no electrostatic discharges can build up in the potentially explosive atmosphere.
▶ Do not use the device in areas where there are powerful chargegenerating processes, mechanical reaming and cutting processes,
the spraying of electrons (e.g. in the vicinity of electrostatic coating
equipment) as well as pneumatically conveyed dust.
▶ Clean the device surface by gently wiping it with a damp or
antistatic cloth only.
▶ Fluid housings made of brass must not be used in atmospheres
containing acetylene.

6.2

Block assembly

Valve blocks are preferably made up so that all units have the same
coil power consumption. If different coil power consumption values
are used in a single valve block, then the technical data for thecoil with the highest power rating must be used to determine thetemperature class. In this case the ambient temperature must be
no higher than +40 °C (+104 °F).

AC10Specific conditions of use

6.3

Operating conditions

The valve provides a cooling function for the solenoid coil. The
solenoid coil may not be operated without a valve. The valve
body must meet the following requirements:• Material
Metal (brass, aluminium, stainless steel) or polyamide• Minimum dimensions
32 mm x 32 mm x 10 mm
A larger valve body with a higher heat-dissipating capability canbe used at any time.
The solenoid coils designed for individual installation may not be
used for block assembly.
The solenoid coils designed for block assembly are suitable forboth block assembly and for individual installation.
