Installation position: random;

Magnet system mounted in the upper

position prevents deposits settling in the

core chamber and increases the service

life

Before installation, clean the connecting fl ange and pipework

of any soiling

Observe fl uidic supply and working ports

Preferably use PTFE tape for thread sealing

Standard:

Connect pressure port to connection 1 and

vent to connection 3

Exception:

On 3/2-way valve with Namur fl ange

Connect pressure port to connection 3 and

vent to connection 1

Electrical Connection of Type 0590 EEx m

Observe the voltage and current type as per the rating plate

Voltage tolerance ±10 %

With DC voltage, observe the correct polarity

Coil has a 3 m long moulded cable

Always connect the PE conductor and check for

continuity

WARNING!
Operate the device only with back-up fuse in
accordance with the PTB certifi cate

Electrical Connection of Type 0590 EEx i

WARNING!

The coil AC 10 with protection type EEx ia IIC T6 in
accordance with PTB 01 ATEX 2101 is designed for
operation at 24 V DC outputs with intermediate related
intrinsically safe device (partition module or barrier)
(see circuit diagram).
Corresponding devices are available from various manu-
facturers (see Bürkert list on suitable “Partition modules
/ barriers for intrinsically safe valves”).
When selecting the device, the resistance of the con-
necting lead between the device and the valve must be
taken into consideration as part of the rated coil resistance
(see table).
Pay attention to the correct polarity when connecting.
Please observe the installation instruction for device
plug sockets!

In the case of EEx i: The device

If the solenoid still does not pick up, the following could be
the cause:

- Short

circuit

- Interruption in power supply

- Blown fuse (in the case of EEx i in the device)

- Core or core chamber soiling

CAUTION!
Risk of damage
Do not use the solenoid coil as a screwing lever and do
not install the valve casing under strain.
Use suitable tools and supports, where necessary.
