Wiring diagram
1) The reversing contactors are designed for a lifetime of 2 million starts.
2) For the assignment of AUMA power classes, please refer to electrical data on actuator.
3) All input signals must be supplied with the same potential.
4) Not possible for low temperature versions with heating system
5) Not possible in combination with PTC tripping device

SA 07.2 SA 16.2/SAR 07.2
Standard:
EMERGENCY operation, behaviour programmable
Digital input low active, reaction can be selected: Stop, move to end position CLOSED,
-
move to end position OPEN, move to intermediate position
Torque monitoring can be by-passed during EMERGENCY operation.
-
Thermal protection can be by-passed during EMERGENCY operation (only in combi-
-
nation with thermoswitch in the actuator, not with PTC thermistor).
Options:
Enabling local controls via digital input Enable LOCAL. Thus, the actuator operation can
be enabled or disabled via push buttons on the 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.
EMERGENCY stop button (latching) interrupts electrical operation irrespective of the
selector switch position.
Interlock, enabling the operation commands OPEN or CLOSE via digital inputs Interlock
OPEN or Interlock CLOSE
Standard:
Torque monitoring: Valve overload protection (adjustable), results in switching off and
generates fault indication
Motor temperature monitoring (thermal monitoring), results in switching off and generates
fault indication
Monitoring the heater within the 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 indication
Automatic correction of the direction of rotation upon wrong phase sequence (3-phase
AC currrent)
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 positions 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 setting, operation and fault history:
Status signals in compliance with NAMUR recommendation NE 107: "Failure",
-
"Function check", "Out of specification", "Maintenance required"
Torque characteristics
- 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:
AUMA plug/socket connector (S) with screw-type connection and M-threads
Options:
Pg-threads, NPT-threads, G-threads, special threads
Gold-plated control contacts (pins and sockets)
Parking frame for wall mounting of the disconnected plug
Protection cover for plug compartment (when plug is removed)
