POSITIONMASTER EDP300 DIGITAL POSITIONER | DS/EDP300-EN REV. J

Brief description
The PositionMaster EDP300 is an electronically configurable
positioner with communication capabilities designed for
mounting on pneumatic linear or rotary actuators. It features
a small and compact design, a modular construction, and an
excellent cost-performance ratio.
Fully automatic determination of the control parameters and
adaptation to the positioner allow for considerable time
savings as well as optimum control behavior.
Pneumatics
An I/P module with subsequent pneumatic amplifier is used
to control the pneumatic actuator. The well-proven I/P
module proportionally converts the permanent electrical
setpoint signal from the CPU into a pneumatic signal used to
adjust a 3/3-way valve.
Dosing of the air flow for pressurizing or depressurizing the
actuator is continuously adjusted. As a result, excellent
control results are achieved. When reaching the setpoint, the
3/3-way valve is closed in center position to minimize the air
consumption.
The pneumatic system can be supplied in four versions: for
single acting and double acting actuators and each with the
‘fail-safe’ / ‘fail-freeze’ safety function.
‘Fail-safe’ safety function
If the electric power supply fails, the positioner output 1 is
depressurized and the return spring in the pneumatic
actuator moves the valve to the safe position. In case of a
‘double-acting’ version, output 2 is additionally pressurized.
‘Fail-freeze’ function
If the electric power supply fails, the positioner Output 1
(and Output 2 if applicable) is closed and the pneumatic
actuator blocks the valve in the current position. If the
compressed air supply power fails, the positioner
depressurizes the actuator.
Use
The positioner has a built-in LCD indicator with a multi-line
LCD display and 4 operating buttons for commissioning,
configuration, and monitoring during live operation.
Alternatively, the appropriate DTM/EDD can be used via the
available communication interface.
Communication
The positioner supports HART5® and HART7®
communication.
Inputs / Outputs
In addition to its input for the analog position setpoint, the
positioner is equipped with a digital input which can be used
to activate control system functions in the device. A digital
output allows you to output collective messages (alarms /
faults).
Modular design
The basic model can be enhanced at any time by retrofitting
optional equipment.
Option modules for analog and digital feedback, an
emergency shutdown module, and pressure sensors for valve
diagnostics can be installed.
A module for a universal analog input can also be installed to
which any device supplying a 4 to 20 mA signal can be
connected.
Additionally, a mechanical position indicator, proximity
switches or 24 V microswitches are available for indicating
the position independently of the mother board function.
Diagnostics
The positioner has three optional pressure sensors which can
be used for reliable diagnostics of the valve, the pneumatic
drive, and the positioner.

General
Microprocessor-based position control in the positioner
optimizes control. The positioner features high-precision
control functions and high operational reliability. Due to their
elaborate structure and easy accessibility, the device
parameters can be quickly adapted to the respective
application.
The total range of parameters includes:
• Operating parameters
• Adjustment parameters
• Operation monitoring parameters
• Diagnosis parameters
• Maintenance parameters
Operating parameters
The following operating parameters can be set manually if
required:
Setpoint signal
0 to 100 % freely selectable for split-range operation
For 4 to 20 mA and HART® version:
• Signal min. 4 mA, max. signal 20 mA (0 to 100 %)
• Min. range 20 % (3.2 mA)
• Recommended range > 50 % (8.0 mA)
Action (setpoint signal)
Increasing:
Position value 0 to 100 % = direction 0 to 100 %
Decreasing:
Setpoint signal 100 to 0 % = direction 0 to 100 %
Characteristic curve (travel = f {setpoint signal})
Linear, equal percentage 1:25 or 1:50 or 25:1 or 50:1 or freely
configurable with 20 reference points.
Travel limit
The positioning travel, i.e. the stroke or angle of rotation, can
be reduced as required within the full range of 0 to 100 %,
provided that a minimum value of 20% is observed.
Shut-off function
This parameter can be set separately for each end position.
When the respective configured limit value is exceeded, the
shut-off function causes immediate travel of the actuator
until reaching the set end position.
When the shut-off value is set to “0”, the position is further
controlled, even in the respective end position.
Travel time prolongation
This function can be used to increase the max. travel time for
full travel. This time parameter can be set separately for each
direction.
Switching points for the position
You can use these parameters to define two position limits
for signaling (see option “Module for digital position
feedback”).
Alarm output
The alarms generated in the positioner can be polled via the
digital output as a collective alarm.
The desired information can be selected via the LCD display
or remotely via the configuration program.
The output can be set to “active high” or “active low”, as
required.
Digital input
For the digital input, one of the following safety options can
be selected. You may use the LCD display or configuration
program to select an option.
• No function (default)
• Move to position substitute value (freely selectable)
• Start "Partial Stroke Test"
• Ventilate output 1, evacuate output 2
• Ventilate output 2, evacuate output 1
• Service required
• Move to 0 % position
• Move to 100 % position
• Hold previous position
• Disable local configuration
• Disable local configuration and operation
• Disable all access (no local or remote access via a PC)
