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 specifications on the
• 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 formed 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.
- approval plate).
• 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 operating 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 components, 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.
The coil AC19 was developed with due consideration
given to the accepted safety rules and is state-of-the-art.
However, dangers can still arise.
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).

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 neither 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!
