Features and functions
Auxiliary voltage 24 V DC: max. 100 mA for supply of control inputs, galvanically isolated
from internal voltage supply.
Standard:
Voltage output
Auxiliary voltage 115 V AC: max. 30 mA for supply of control inputs, galvanically isolated
from internal voltage supply
(Not possible in combination with PTC tripping device)
Option:
2 analogue outputs:
With position transmitter option: Output of travel and torque as continuous values between 0/4 and 20
mA
Analogue output (option)
2 analogue inputs:
With positioner/process controller option: Input of actual position value/actual process value as continuous
values between 0/4 and 20 mA
Analogue input (option)
●
Selector switch LOCAL - OFF - REMOTE (lockable in all three positions)
●
Push buttons OPEN, STOP, CLOSE, RESET
-
Local STOP
The actuator can be stopped via push button STOP of local controls if the selector
switch is in position REMOTE. (Not activated when leaving the factory.)
●
6 indication lights:
-
End position and running indication CLOSED (yellow), torque fault CLOSE (red),
motor protection tripped (red), torque fault OPEN (red), end position and running
indication OPEN (green), Bluetooth (blue)
●
Graphic LC display: illuminated
Standard:
Local controls
●
Special colours for the indication lights:
-
End position CLOSED (green), torque fault CLOSE (blue), torque fault OPEN
(yellow), motor protection tripped (violet), end position OPEN (red)
Options:
Bluetooth class II chip, version 2.1: With a range up to 10 m in industrial environments, supports the
SPP Bluetooth profile (Serial Port Profile).
Required accessories:
●
AUMA CDT (Commissioning and Diagnostic Tool for Windows-based PC)
●
AUMA Assistant App (Commissioning and Diagnostic Tool for Android devices)
Bluetooth
Communication interface
●
Selectable type of seating, limit or torque seating for end position OPEN and end po-
sition CLOSED
●
Torque by-pass: Adjustable duration (with adjustable peak torque during start-up time)
●
Start and end of stepping mode as well as ON and OFF times can be set individually
for directions OPEN and CLOSE, 1 to 1,800 seconds
●
Any 8 intermediate positions between 0 and 100 %, reaction and signal behaviour
programmable
●
Running indication blinking: can be set
●
Positioner:
-
Position setpoint via HART interface
-
Automatic adaptation of dead band (adaptive behaviour selectable)
-
Change-over between OPEN-CLOSE control and setpoint control via HART inter-
face
Standard:
Application functions
●
PID process controller: with adaptive positioner, process setpoint via 0/4 – 20 mA
analogue input or HART, actual process value via 0/4 – 20 mA analogue input
●
Automatic deblocking: Up to 5 operation trials, travel time in opposite direction can be
set
Option:
●
EMERGENCY operation (programmable behaviour)
-
Digital input: Low active (option)
-
Reaction can be selected: STOP, run to end position CLOSED, run to end position
OPEN, run to intermediate position
-
Torque monitoring can be by-passed during EMERGENCY operation.
-
Thermal protection can be by-passed during EMERGENCY operation (only in
combination with thermoswitch within actuator, not with PTC thermistor).
Standard:
Safety functions
●
Enabling local controls via digital input Enable LOCAL. Thus, actuator operation can
be enabled or disabled via push buttons on the local controls.
●
Interlock for main/by-pass valve: Enabling the operation commands OPEN or CLOSE
via two digital inputs
●
PVST (Partial Valve Stroke Test): programmable to check the function of both actuator
and actuator controls: Direction, stroke, operation time, reversing time
