Features and functions
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
●
Operation profile with any 8 intermediate positions: Position can be set between 0 and
100 %, reaction and signal behaviour programmable, positioning accuracy < 0.2 %
●
Speed profile with up to 10 ranges, speed can be individually adjusted for positions
OPEN and CLOSED for each range
●
Running indication blinking: can be set
●
Speed source can be selected (REMOTE, LOCAL)
●
4 internal nominal speeds can be programmed (and selected in LOCAL)
●
Nominal speed source can be selected for REMOTE (binary, analogue, fieldbus)
●
Soft start, soft stop (0.1 s – 10 s can be selected)
●
Synchronous link (synchronous operation of two actuators)
●
Positioner:
-
Position setpoint via fieldbus interface
-
Programmable behaviour on loss of signal
-
Automatic adaptation of dead band (adaptive behaviour selectable)
-
Change-over between OPEN-CLOSE control and setpoint control via fieldbus
-
Modulating duty with proportional operation (2 % – 20 %)
Standard:Application functions
●
PID process controller: with adaptive positioner, via 0/4 – 20 mA analogue inputs for
process setpoint and actual process value
●
Automatic deblocking: Up to 5 operation trials, travel time in opposite direction can be
set
●
Static and dynamic torque recording for both rotation directions with torque measure-
ment flange as additional accessory
Options:
●
EMERGENCY operation (programmable behaviour)
-
Via additional input (option, low active) or via fieldbus interface
-
Reaction can be selected: STOP, run to end position (OPEN, CLOSED) or inter-
mediate position at defined speed
-
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 Enable LOCAL digital input: 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
●
EMERGENCY Stop push button (latching): interrupts electrical operation, irrespective
of the selector switch position.
●
PVST (Partial Valve Stroke Test): programmable to check the function of both actuator
and actuator controls: Direction, stroke, operation time, reversing time
Options:
●
Valve overload protection: adjustable, results in switching off and generates fault signal
●
Motor temperature monitoring (thermal monitoring): results in switching off and generates fault indic-
ation
●
Monitoring the heater within actuator: generates warning signal
●
Monitoring of permissible on-time and number of starts: adjustable, generates warning signal
●
Operation time monitoring: adjustable, generates warning signal
●
Automatic correction of rotation direction upon wrong phase sequence (3-ph AC current)
