Intended use

2 INTENDED USE

Improper use of the Type AC10 solenoid may be dangerous

to people, nearby equipment and the environment.

The TypeAC10 solenoid is used to operate valves that

control gaseous or liquid media.

▶A valve operated with the Type AC10 solenoid is to be used

exclusively with the permissible media specied in the data

sheet and for use in explosion group IIC, category 3G and/or

explosion group IIIC, category 3D and temperature class T4

(see details on the type label for the Ex area).

▶The solenoid may only be used for the applications specied

in chapter „5 Operational conditions of the devices“ and in

connection with the Type 2509 or Type 2513 cable plugs

available from Bürkert.

Variants with UL listing are only authorised for Type 2509

cable plugs.

▶Prerequisites for safe and trouble-free operation of the

device are proper transport, storage and installation as well

as careful operation and maintenance. Any other or addi-

tional use is not considered part of the intended use. Bürkert

will not be liable for any damage resulting from this. The user

alone bears the risk.

▶Only use the device as intended.

2.1 Ex approval

The explosion protect approval is only valid if you use the modules

and components authorised by Bürkert as described in these oper-

ating instructions. The Type AC10 solenoid with Type 2509 or Type

2513 cable plug may be used only in combination with the additional

components approved by Bürkert, otherwise the explosion pro-

tection approval is terminated. In the event of unauthorised changes

to the device, modules or components, the explosion protection

approval is also void. The EU type approval test certicate and the

following IECEx certicates have been issued by:

3 BASIC SAFETY INSTRUCTIONS

These safety instructions do not take into account any

unforeseen circumstances and events which occur during instal-

lation, operation and maintenance.

The operator is responsible for observing the location-specic

safety regulations, also with reference to personnel.

Risk of injury due to high pressure in the system or device.

▶Before working on the system or device, switch o the pres-

sure and ventilate or empty the lines.

Risk of injury due to electric shock.

▶Before working on the system or device, switch o the

power supply and secure against reactivation.

▶Observe the applicable accident prevention and safety regu-

lations for electrical devices.

Risk of burns or re from hot device surfaces due to prolonged

operation.

The solenoid can become very hot during continuous operation.

▶Keep the device away from highly ammable substances

and media and do not touch with bare hands.

Type AC10, II 3G/D Ex

English

Basic safety instructions

Risk of explosion.

Solenoids and valve bodies form a closed system after instal-

lation. When used in a potentially explosive atmosphere, there is a

risk of explosion when the system is opened while in operation.

▶Do not dismantle or open the system during operation.

Risk of explosion due to electrostatic discharge.

If there is a sudden discharge of electrostatically charged devices

or people, there is a risk of explosion in the Ex area.

▶Use suitable measures to ensure that electrostatic charges cannot

occur in the Ex area.

▶The device must not be used in areas with processes that

generate heavy charges, involve automated grinding or cut-

ting, the spraying of electrons (e.g. near electrostatic painting

equipment) or generate pneumatically propelled dust.

▶Clean the device surface by gently wiping it with a damp or

anti-static cloth only.

To avoid the risk of explosions, the following must be observed

in the Ex area:

▶Information about temperature class, ambient temperature,

degree of protection and voltage on the type label for the Ex

area.

▶Installation, operation and maintenance may only be per-

formed by qualied personnel.

▶Observe applicable safety regulations (as well as national

safety regulations), as well as the general rules for the tech-

nology during setup and operation.

▶Repairs may only be carried out by the manufacturer.

▶Do not subject the device to mechanical and/or thermal

stresses which exceed the limits described in the operating

instructions.

▶Do not disconnect connector while circuit is live.

General hazardous situations.

To prevent injuries, observe the following:

▶Secure the device or system against unintentional activation.

▶Note the ow direction when installing.

▶Following an interruption in the power supply, ensure that

the process is restarted in a controlled manner.

▶Do not use the device as a lever when screwing the valve

into the line.

5 OPERATIONAL CONDITIONS OF

THE DEVICES

5.1 Special conditions

▶Only use the device in an area which has pollution degree2

at least, as dened in IEC60664-1.

▶Ensure that the transient protection has been set to a value

which does not exceed 140% of the rated peak voltage

value on the supply connections of the device.

▶Use the device only in a mounting position that is not subject

to mechanical stress.

Installation advice

The information for the authorised ambient temperature con-

cerns the single installation of the solenoids. If multiple sole-

noids are installed in one valve block:

▶Prevent mutual heating by using a suitable distance.

Operational conditions of the devices

WARNING!

Hazard due to electrostatic discharge.

If there is a sudden discharge of electrostatically charged

devices or people, there is a risk of explosion in the Ex area.

▶Use suitable measures to ensure that electrostatic charges

cannot occur in the Ex area.

▶The device must not be used in areas with processes that

generate heavy charges, involve automated grinding or cut-

ting, the spraying of electrons (e.g. near electrostatic painting

equipment) or generate pneumatically propelled dust.

▶Clean the device surface by gently wiping it with a damp or

anti-static cloth only.

5.2 Operating conditions

The valve fulls a cooling function for the solenoid.

The solenoid must not be operated without a valve. The valve

body must meet the following prerequisites:

• Material

Metal (brass, aluminium, stainless steel) or polyamide

• Minimum dimensions

32mmx32mmx10mm

A larger valve body with better thermal conductivity may be used

at any time.

Solenoids intended for single installation must not be used for

block installation.

5.3 Operating temperature range

Pay attention to the operating temperature range for each type

listed in the electrical data.
