Intended use
3 INTENDED USE
Incorrect use of the device can be dangerous to people,
nearby equipment and the environment.
The device is designed for the open-loop control and closed-loop
control of media.
▶In the potentially explosion-risk area the device may be used only
according to the specification on the separate Ex type label. For
use observe the additional information enclosed with the device
together with safety instructions for the explosion-risk area.
▶Devices without a separate Ex type label may not be used in a
potentially explosive area.
▶The device must not be exposed to direct sunlight.
▶Pulsating direct voltage (rectified alternating voltage without
smoothing) must not be used as operating 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 “„Description of
System“ - „Technical Data“ in this manual and in the valve manual
for the respective pneumatically actuated valve.
▶The device may be used only in conjunction with third-party devices
and components recommended and authorised by Ebro.
▶In view of the wide range of possible application cases, check
whether the device is suitable for the specific application case
and check this out if required.
▶Correct transportation, correct storage and installation and care-
ful use and maintenance are essential for reliable and faultless
operation.
▶Use the device only as intended.
3.1 Restrictions
If exporting the system/device, observe any existing restrictions.
4 BASIC 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 – the operator is responsible for observing
these regulations, also with reference to the installation personnel.
Danger – high pressure!
▶Before loosening the pneumatic lines and valves, turn off the
pressure and vent the pneumatic lines.
Risk of electric shock!
▶Before reaching into the device or the equipment, switch off the
operating voltage and secure to prevent reactivation!
▶Observe applicable accident prevention and safety regulations
for electrical equipment!
Risk of burns/risk of fire if used continuously through hot
device surface!
▶Keep the device away from highly flammable substances and
media and do not touch with bare hands.
General hazardous situations.
To prevent injury, ensure that:
▶That the system cannot be activated unintentionally.
▶The device may be operated only when in perfect condition and
in consideration of the operating instructions.
▶Installation and repair work may be carried out by authorised
technicians only and with the appropriate tools.

General information
▶After an interruption in the operating voltage or pneumatic sup-
ply, ensure that the process is restarted in a defined or con-
trolled manner.
▶Do not supply the supply pressure connection of the system
with aggressive or flammable mediums.
▶Do not supply the supply pressure connection with any liquids.
▶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.
▶The general rules of technology apply to application planning
and operation of the device.
NOTE!
Electrostatic sensitive components / modules!
The device contains electronic components which react sensitively
to electrostatic discharge (ESD). Contact with electrostatically
charged persons or objects is 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 to
minimise or avoid the possibility of damage caused by sudden
electrostatic discharge!
• Also ensure that you do not touch electronic components when
the operating voltage is present!

Description of System
6 DESCRIPTION OF SYSTEM
6.1 General description
The positioner Type EP 501 / process controller Type EP 501 C
is a digital, electro-pneumatic position controller for pneumatically
actuated proportional valves. The device incorporates the main
function groups
- Position sensor
- Microprocessor electronics
- Electro-pneumatic control system
The position sensor measures the current positions of the proportional
valve.
The microprocessor electronics continuously compare the current position
(actual value) with a set-point position value specified via the standard
signal input and supplies the result to the positioner/process controller.
If there is a control difference, the electro-pneumatic control system
corrects the actual position accordingly.
The device is operated with a 128 x 64 dot matrix graphics display
and a keypad with 4 keys.
6.2 Designs
6.2.1 Type EP 501, positioner
The position of the actuator is regulated according to the position
set-point value. The position set-point value is specified by an external
standard signal (or via field bus).
6.2.2 Type EP 501 C, process controller
Type EP 501 C also features a PID controller which, apart from actual
position control, can also be used to implement process control (e.g.
level, pressure, flow rate, temperature) in the sense of a cascade control.
The process controller is linked to a control circuit. The position set-
point value of the valve is calculated from the process set-point value
and the actual process value via the control parameters (PID controller).
The process set-point value can be set by an external signal.
6.2.3 Type EP 501 L remote operation with external
position sensor
In case of this model, type EP 501 C has no internal position
sensor in the form of a rotary position sensor, but is connected to
an external 4–20 mA remote sensor. As this is connected via the
analog interface, type EP 501 L can be operated as a positioner
(position controller) only.
