AUMA SQEx 05.2 User Manual

Features and functions
●
EMERGENCY operation (programmable behaviour)
-
Via additional input (option, low active) 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 viafieldbus 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
●
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)
Monitoring functions
●
Electronic device ID with order and product data
●
Operating data logging: 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.
