Features and functions
Safety functions
Standard
EMERGENCY operation (programmable behavior)
- Digital input: Low active
- 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).
Monitoring functions
Valve overload protection: adjustable, results in
switching off and generates fault signal
Motor temperature monitoring (thermal
monitoring): results in switching off and
generates fault indication
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)
Diagnostic functions
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.
Stored torque characteristics can be
displayed.
