1. OPERATING INSTRUCTIONS

The operating instructions describe the entire life cycle of the device.

Keep these instructions in a location which is easily accessible to

every user and make these instructions available to every new owner

of the device.

WARNING!

The operating instructions contain important safety

information!

Failure to observe these instructions may result in hazardous

situations. The operating instructions must be read and

understood.

• Carefully read the operating instructions before using the device.

• In particular observe the chapter entitled "Intended use", and

"General safety instructions" as well as the chapter entitled

"Application conditions of the coil AC19".

Intended Use

2. INTENDED USE

WARNING!

Incorrect use of the coil AC19 can be dangerous to people,

nearby equipment and the environment.

• The solenoid coil AC19 is used to actuate valves which control

gaseous or liquid media. It was designed for use in explosion

group II, category 2D, Ex mbD, IP64, T130°C and in explosion

group II, category 2G and temperature class T4 (see specifica-

tions on the - approval plate).

• The coil AC19 is always attached to the core feed pipe of the

valve fitting and secured with a nut. In this way coil and valve

body are connected in such a way that a closed system is for-

med which may also be used as a category 2 device to control

petrol in petrol pumps. For this application a valve body made of

metal (brass, aluminium or stainless steel) must be used.

When using the device, observe the permitted data, operating

conditions and application conditions which

– are specified in the operating instructions for the solenoid coil

AC19, on the rating plate, in the contract documents

– as well as in the operating instructions for the solenoid valve

actuated with the coil.

The coil may be used only in conjunction with third-party devices

and components recommended and authorised by Bürkert.

Correct transportation, correct storage and installation and careful

use and maintenance are essential for reliable and problem-free

operation.

• Any other use is considered improper use.Bürkert is not liable

for any resulting damage. The user alone bears the risk.

• Use the device only as intended.

2.1. Restrictions

If exporting the system/device, observe any existing restrictions.

2.1.1. Explosion protection approval

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

and components authorised by Bürkert, as described in these ope-

rating instructions.

The coil AC19 may be used only in combination with the valve types

released by Bürkert, otherwise the explosion protection approval will

be terminated!

If you make unauthorised changes to the system, the modules or com-

ponents, the explosion protection approval will be terminated.

General Safety Instructions

3. GENERAL 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, whereby the operator is responsible for their

compliance, by the installation personnel too.

DANGER!

Danger of explosion!

Following installation, solenoid coil and valve body form a closed

system. If used in the EX area, there is a danger of explosion if the

system is opened during operation!

• The system must not be disassembled during operation.

Danger of explosion caused by electrostatic charge!

If there is a sudden discharge from electrostatically charged devices

or persons, there is a danger of explosion in the EX area.

• Take appropriate measures to prevent electrostatic charges in the

EX area.

• Clean the device surface of the solenoid valve by gently wiping

it with a damp cloth

DANGER!

Risk of electric shock!

There is a serious risk of injury when reaching into the equipment.

• Only trained electrical engineers may work on the electrical

system.

• Before starting work, always switch off the power supply and

safeguard to prevent re-activation!

• Observe applicable accident prevention and safety regulations

for electrical equipment!

Danger of burns/danger of fire during long-term operation!

The solenoid coil may become very hot during long-term operation.

• Take hold of a device which has been running for a prolonged

period with protective gloves only.

Danger – high pressure!

There is a serious risk of injury when reaching into the system.

• Only skilled and instructed personnel may work on the system

with suitable tools.

• Before disconnecting lines and valves, switch off the pressure

and bleed the lines.

• During installation note the direction of flow.

• Observe applicable accident prevention and safety regulations

for pressurised devices!

• After an interruption in the power supply or fluid supply, ensure

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

General Information

WARNING!

General hazards!

• Do not use the valve fitting or the complete device as a lever to

screw the valve into the line system.

• Do not put any loads on the housing (e.g. by placing objects on

it or standing on it).

• Do not make any external modifications to the device housings.

Do not paint the housing parts or screws.

Unintentional activation or unauthorised impairment of the system

may cause general hazardous situations through to physical injury.

• Take appropriate measures to prevent the system from being

accidentally actuated!

• Do not make any unauthorised changes to the system.

Non-observance of the generally acknowledged safety rules may

cause general hazardous situations through to physical injury.

• Observe the generally acknowledged safety rules for resource

planning and operation of the coil AC19 and the associated

solenoid valve.

Operate the coil AC19 and the associated solenoid valve in

perfect working order only and in accordance with the operating

instructions.

5. APPLICATION CONDITIONS

5.1. Special conditions

5.1.1. Short-circuit protection

To protect each solenoid against short-circuit, a fuse (max. 3 x Ib in

accordance with IEC 60127-2-1), corresponding to the rated current,

or a motor protection switch with short-circuit and thermal quick release

(set to rated current) must be connected upstream.

• At very low rated currents of the solenoid the fuse with the lowest

current value is adequate according to the stated IEC standard.

This fuse may be housed in the associated supply unit or must be

connected separately upstream.

• The fuse rated voltage must be the same or higher than the indicated

nominal voltage of the solenoid.

• The interruption rating of the fuse link must be the same or higher than

the maximum short-circuit current to be accepted at the installation

site (usually 1500 A).

Application conditions

5.3. Installation conditions

The solenoid coils Type AC19-..-.-PF09 to Type AC19-..-.-PF10 are

suitable for single installation only.

The connection cables must be laid permanently to protect against

damage.

Also observe the specifications in the chapter entitled

"Technical Data".

5.4. Application in petrol pumps

DANGER!

Danger of explosion!

Following installation, solenoid coil and valve body form a closed

system. If used in the EX area, there is a danger of explosion if the

system is opened during operation!

• The system must not be disassembled during operation.

• The valve body may be repaired by the manufacturer only.

Solenoid valves together with the coil AC19 may be used as

category 2 devices only for the control of petrol if there is no air

and no oxygen in the closed system.

• Ensure that the closed system contains no air or oxygen or

cannot be penetrated by air or oxygen.

• When switching off or starting up the system, ensure that nei-

ther air nor oxygen has penetrated the system.

If the system is used as a category 2 device, only valve bodies

made of metal can ensure the required safety for the control of

petrol in petrol pumps!

• Use only valve bodies made of metal (brass, aluminium or

stainless steel) for the control of petrol in petrol pumps with

category 2 devices.
