Features and 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 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.
