The Operating Instructions
1. THE 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.
The operating instructions contain important safety
information!
Failure to observe these instructions may result in hazardous situa-
tions. 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“.
1.1. Symbols
In the instructions, the following symbols are used to identify important
information:
DANGER!
Warns of an immediate danger!
• Failure to observe the warning may result in a fatal or serious injury.
WARNING!
Warns of a potentially dangerous situation!
• Failure to observe the warning may result in serious injuries or
death.
CAUTION!
Warns of a possible danger!
• Failure to observe the warning may result in moderately serious
or minor injuries.

Intended Use
2. INTENDED USE
Incorrect use may be a hazard to people, nearby equipment
and the environment.
• The device serves exclusively as a solenoid valve for the media
stated in the data sheet and for use in Explosion Group IIC,
Category 2G and Temperature Class T4 or T5 (see data on the
- Ex approval plate).
• The device may be used only in category 2D with the temperatures
T135 °C and/or 100 °C as well as for the designated application
cases specified in chapter “5. Application Conditions” and in con-
junction with third-party devices and components recommended
and authorized by Bürkert.
• The applied ignition protection types are the pressure-resistant
casing “d” with increased safety “e”. The safety fuse incorpo-
rated in version PD29 is executed in ignition protection type
encapsulation “m”. The proximity switch, which can be optionally
incorporated in all versions, is executed in ignition protection
type intrinsic safety “ia”.
The composition of the ignition protection code follows the igni-
tion protection types of the components used in each case.
• 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 device, observe any existing restrictions.
2.2. Ex-Approval
The Ex approval is only valid if you use the modules and components
authorised by Bürkets in such a way as described in this operating
manual.
The coil type 0770/0780 may only be used in combination with addi-
tional components that have been approved by Bürkert. Otherwise, the
Ex approval will expire!
If you make any unauthorized changes to the device, the modules or
the components, the Ex approval will also expire.
The EC Qualification Test Certificate PTB 03 ATEX 1030 X and the
IECEx Certificate of Conformity IECEx PTB 05.0026X has been
drawn up by the:
PTB (Physikalisch Technische Bundesanstalt)
Bundesallee 100
38116 Braunschweig
who also audited the manufacture (CE0102).

General Safety Instructions
2.3. Special instructions in explosion-risk
areas
WARNING!
Danger caused by electrostatic charge!
If there is a sudden discharge from electrostatically charged devices
or persons, there is a danger of explosion in the explosion-risk area.
• Take appropriate measures to prevent electrostatic charges in
explosion-risk areas.
• Clean the device surface by gently wiping it with a damp or
antistatic cloth only.
Additional special conditions can be found under “5.1” of
these operating instructions.
3. GENERAL SAFETY INSTRUCTIONS
These safety instructions do not take into account
• any contingencies or events which may occur during the installation,
operation and maintenance of the devices.
• local safety regulations, the observance of which is the responsibility
of the operator, also with respect to the installation personnel.
Danger of explosion!
• The device is a sealed system. It must not be opened
Danger of electrostatic charge!
Acute risk of injury from hazardous structure-borne voltage!
Risk of damage to the device due to short circuit!
• Before starting work, switch off the power supply and secure to
prevent it being switched on again!
• Observe the applicable accident prevention and safety regula-
tions for electrical devices!
Danger - high pressure!
• There is a serious risk of injury when reaching into the
equipment.
• Before loosening the lines and valves, turn off the pressure and
vent the lines.
• Observe the currently valid accident prevention and safety
regulations!

General Information
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 by gently wiping it with a damp or
antistatic cloth.
General hazardous situations.
To prevent injury, ensure that:
• That the system cannot be activated unintentionally.
• That no unauthorized changes are performed on the system.
• Only expert and instructed personnel with appropriate tools
carry out any work on the system.
• The device may be operated only when in perfect condition and
in consideration of the operating instructions.
• The general rules of technology apply to application planning
and operation.

Application Conditions
5. APPLICATION CONDITIONS
5.1. Special conditions
5.1.1. Short-circuit protection
Each electromagnet shall be provided on the line with a short-circuit
protection in the form of a fuse designed to meet the magnet starting
current (max. 3 x Irating in accordance with IEC 60127-2-1) or a
motor overload trip instantaneous short-circuit and thermal release
(Adjustment to match the pull-in current).
• At very low pull-in currents of the solenoid the fuse with the lowest
current value is adequate according to the stated IEC standard.
This fuse may be mounted in the associated supply unit or must
be connected in series separately.
• The rated voltage of the fuse must be equal to or larger than the
quoted nominal voltage of the magnet.
• The switch-off capability of the fuse cartridge must be equal to or
greater than the maximum theoretical short-circuit current at the
installation location (normally 1500 A).
• In the case of versions PD30 of the solenoid, short-circuit pro-
tection must be assured by the operator.
• In the case of version PD29 of the solenoid, the fuse is installed in
the terminal box of the device.
More detailed descriptions are to be found in the section
“6. Technical data / Safe operation”.
Fuse ... A
5.1.2. Operation with associated valve body
The solenoid coils Type 77. / 78. may only be operated with a valve
body satisfying the following requirements.
For the valve body, the following materials may be used:
• metal (brass, aluminium, stainless steel) or
• plastics (e,g, polyamide PA 6 GV ...)
5.1.3. Manual operation / approximity switch
The solenoid armature can be manually operated via the push
button. The push button may be locked by depressing and turning
by 90°.
As an alternative to manual operation, the solenoid can be equipped
with a proximity switch. The internal code for this version is CF 15.

Technical data / Safe operation
5.1.4. Model with a terminal box
DANGER!
Risk of explosion!
• Only permanently laid cables and wiring may be inserted.
• The operator must provide suitable stress relief.
• Wires with an outside diameter of 6 to 13 mm may be used.
Observe the maximum thermal loading of the cables or wires to
be inserted.
• The inserted break-off seal must be matched to the diameter of
the cable or wire.
• The rated cross-section of the cable or wire strands must be at
least 0.75 mm² and may not exceed 2.5 mm².
• The screws for fixing the cover of the terminal box must be tight-
ened with a torque of 1 Nm (± 5 %).
The solenoid coils may also be executed with a terminal box, with
or without fuse/contactor (to separate Design Type Inspection Cer-
tificate) as desired.
For protection against inadvertent opening of the cover, the latter
bears the marking:
Open only when the voltage is switched off!
