SAR 16.2 Control unit: electronic (MWG)
Standard: 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).
Options: 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 HART 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
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)
Electronic device ID with order and product data
Logging of operating data: A resettable counter and a lifetime counter each for:
-
Motor running time, number of starts, torque switch trippings in end position CLOSED, limit
switch trippings in end position CLOSED, torque switch trippings in end position OPEN, limit
switch trippings in end position OPEN, torque faults CLOSE, torque faults OPEN, motor protection
trippings
Time-stamped event report with history for setting, operation and faults
Status signals according to NAMUR recommendation NE 107: "Failure", "Function check", "Out of
specification", "Maintenance required"
Torque characteristics (for version with MWG in actuator):
-
3 torque characteristics (torque-travel characteristic) for opening and closing directions can be
saved separately.
-
Torque characteristics stored can be shown on the display.
Standard: Monitoring the motor temperature in combination with thermoswitches within actuator
motor
Options: Thermal overload relay in controls combined with thermoswitches within actuator
PTC tripping device in combination with PTC thermistors within actuator motor
Standard: AUMA plug/socket connector with screw-type connection
Option: Gold-plated control plug (sockets and plugs)
Standard: Metric threads
Options: Pg-threads, NPT-threads, G-threads
Terminals or crimp-type connection
Refer to name plate
Via HART interface
Galvanically isolated analogue output 0/4
ation with output contacts.
The HART address is set via HART command 6 or alternatively via the display of AC 01.2 controls (default
value: 0)
20 mA (load max. 500 Ω). Option, only possible in combin-
