Authorized use
2 AUTHORIZED USE
Non-authorized use of the positioner Type EP 501 B may be a
hazard to people, nearby equipment and the environment.
The device is designed for the open-loop control and closed-loop
control of media.
▶Do not expose the device to direct sunlight.
▶A pulsating direct voltage (rectified alternating current without
smoothing) must not be used as supply voltage.
▶During use observe the permitted data, the operating conditions
and conditions of use specified in the contract documents and
operating instructions, as described in chapter “6 Technical
data” in this manual and in the valve manual for the respective
pneumatically actuated valve.
▶In view of the wide range of possible application cases, check
whether the positioner is suitable for the specific application
case.
▶Correct transportation, storage and installation, as well as care-
ful use and maintenance are essential for reliable and faultless
operation.
▶The positioner Type EP 501 B must be used only for its
intended purpose.
2.1 Restrictions
If exporting the system/device, observe any existing restrictions.
3 BASIC SAFETY INSTRUCTIONS
These safety instructions do not make allowance for any
• contingencies and events which may arise during the assembly,
operation, and maintenance of the devices.
• local safety regulations – the operator is responsible for observing
these regulations, also in relation to the installation personnel.
Danger – high pressure!
▶Before loosening lines and valves, turn off the pressure and vent
the lines.
Risk of electric shock!
▶Before reaching into the device or the equipment, switch off the
power supply and secure to prevent reactivation!
▶Observe applicable accident prevention and safety regulations
for electrical equipment!
General hazardous situations
To prevent injuries:
• In a potentially explosive area, the positioner Type EP 501 B may
be used only in accordance with the specification on the separate
Ex rating plate. For the use, observe the additional information
enclosed with the device with safety instructions for the EX area.
• Devices without a separate Ex rating plate may not be used in a
potentially explosive area.

Basic safety instructions
▶Ensure that the system cannot be activated unintentionally.
▶Installation and maintenance work may be carried out only by
authorized technicians with the appropriate tools.
▶After an interruption in the electrical or pneumatic supply,
ensure that the process is restarted in a defined or controlled
manner.
▶The device must only be operated when in a perfect condition
and in consideration of the operating instructions.
▶The general rules of technology must be observed for applica-
tion planning and operation of the device.
To prevent damage to the device:
• Do not supply the pressure supply connection of the system with
aggressive or flammable media.
• Do not supply the pressure supply connection with liquids.
• Do not physically stress the housing (e.g. by placing objects on
it or standing on it).
• Do not make any external alterations to the housing of the device.
Do not paint housing parts or screws.
NOTE!
Electrostatic sensitive components/modules!
The device contains electronic components which react sensitively
to electrostatic discharge (ESD). Contact with electrostatically
charged persons or objects are hazardous to these components.
In the worst case scenario, they will be destroyed immediately or
will fail after start-up.
• Observe the requirements in accordance with EN 61340-5-1
and 5-2 to minimize/avoid the possibility of damage caused by
a sudden electrostatic discharge!
• Also, ensure that you do not touch electronic components when
the supply voltage is present!
The positioner Type EP 501 B was developed with due con-
sideration given to the accepted safety rules and is state-of-
the-art. Nevertheless, dangerous situations may occur.
Failure to observe these operating instructions and the information
contained therein as well as unauthorized tampering with the device
release us from any liability and also invalidate the warranty covering
the devices and accessories!

5.2 General description
The positioner Type EP 501 B is a digital, electro-pneumatic position
controller for pneumatically actuated control valves. The device incor-
porates the main function groups
- Position sensor
- Electro-pneumatic control system
- Microprocessor electronics
The position sensor measures the current positions of the control valve.
The microprocessor electronics continuously compare the current
position (actual value) with a position set-point value specified via the
standard signal input and supplies the result to the position controller.
If there is a control difference, the electro-pneumatic control system
corrects the actual position accordingly.

System description
5.3 AS interface
5.3.1 AS interface connection
AS interface (Actuator Sensor Interface) is a field bus system which
is used primarily for networking binary sensors and actuators (slaves)
with a higher-level control (master).
Bus line
Unshielded two-wire line (AS interface line as AS interface cable
harness) along which both information (data) and energy (power supply
for the actuators and sensors) are transmitted.
Network topology
Freely selectable within wide limits, i.e. star, tree and line networks are
possible. Further details are described in the AS interface specification
(A/B slave model conforms to the version 3.0 specification).
