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
●
Any 8 intermediate positions: can be set between 0 and 100 %, reaction and signal
behaviour programmable
●
Running indication blinking: can be set
●
Positioner
-
Position setpoint via Modbus RTU interface
-
Programmable behaviour on loss of signal
-
Automatic adaptation of dead band (adaptive behaviour selectable)
-
Split range operation
-
Change-over between OPEN-CLOSE control and setpoint control possible viafield-
bus interface
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 aktive) or via fieldbus interface
-
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
●
Release of local controls via fieldbus interface. Thus, actuator operation can be enabled
or disabled via push buttons on local controls.
●
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.)
●
Interlock for main/by-pass valve: Enabling the operation commands OPEN or CLOSE
via fieldbus interface
●
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
●
Phase failure monitoring: results in switching off and generates fault signal
●
Automatic correction of rotation direction upon wrong phase sequence (3-ph AC current)
