FUNCTIONAL SPECIFICATIONS
(Common data for all versions)
Travel Range
Stroke range 8…260 mm (0 3…10 2 in) with standard
feedback levers;
special levers on request
Rotation angle
range
Up to 95° (without mechanical stop) and
up to 300° with a special construction on
request (ECEP EPO256)
Supply
Supply air pressure 1 4…6 bar (20…90 psig)
With spool valve
3) 1 4…7 bar (20…105 psig)
Output to actuator 0 to ~100 % of supply air pressure
(up to 5 5 bar at 6 bar supply air pressure)
Air supply According to ISO 8573-1
Solid particle size and density, class 2
Oil rate, class 3
Pressure dew point 10 K under ambient
temperature
The use of filter regulator for air supply of positioner is
strongly recommended It reduces the air pressure to
actuator’s maximum pressure and keeps it constant
For supply with Natural Gas instead of compressed air please
consult TI EVE0105_G
Response Characteristic 1) 2)
Sensitivity < 0 1 % of travel span
Non-linearity (terminal based
adjustment)
< 0 4 % of travel span
Hysteresis < 0 3 % of travel span
Supply air dependence < 0 1 % / 1 bar (15 psi)
Temperature effect < 0 3 % / 10 K
Mechanical vibration 10…60 Hz up to 0 14 mm
60…500 Hz, up to 2 g
< 0 25 % of travel span

Features
Automatic Startup—(Autostart Functionality)
Automatic determination of the mechanical end positions of
the valve (initial value and final value), IP motor parameters,
direction of action of the spring and control parameter
The control parameters are optimized dynamically during
this routine
This procedure makes a perfect adjustment and optimization
to the actuator possible without additional manual settings!
Several autostart modes are available (details on next page)
Options
• Built-in independent inductive limit switches
• Pressure sensors for monitoring of air supply and out- put
pressure I (y1)
• Additional inputs / outputs:
◊ Position feedback 4…20 mA + binary alarm output, to
be supplied external
◊ 2 binary outputs (position alarms)
◊ 2 binary inputs, to be supplied external
◊ 2 contact inputs, internal supplied
◊ 2 binary in-/outputs, to be supplied external
1) Data measured according to VDI/VDE 2177
2) With stroke 30 mm and lever length 90 mm
3) Spool valve is the type of amplifier used in device SRD991-Cxxxxx-S
4) Standard diaphragm amplifier
