Switchgear Standard: Reversing contactors 2) (mechanically and electrically interlocked)
for motor power up to 1.5 kW
Options: Reversing contactors 2) (mechanically and electrically interlocked)
for nominal motor current up to 18 A (OPEN - CLOSE- duty)
or 16 A (modulating duty)
Thyristor unit
3) (recommended for modulating actuators)

for motor power up to 5.5 kW, 500 V AC, external fuses required
Control Standard: Control inputs 115 V AC, OPEN - STOP - CLOSE (via opto-isolator,
with one common), current consumption: approx. 10 mA per input
Observe min. duration of impulse for modulating actuators
Option: Control inputs 24 V DC, OPEN - STOP - CLOSE (via opto-isolator,
with one common), current consumption: approx. 15 mA per input
Output signals Standard: 5 output relays with gold-plated contacts:
4 potential-free NO contacts with one common:
max. 250 V AC, 0.5 A (resistive load)
Standard configuration:
End position OPEN, end position CLOSED, selector switch REMOTE,
selector switch LOCAL
1 potential-free change-over contact, max. 250 V AC, 0.5A (resistive load)
for collective fault signal
Standard configuration:
Torque fault, phase failure, motor protection tripped
Option: Signals in connection with positioner:
End position OPEN, end position CLOSED
(requires tandem switch within actuator)
Selector switch REMOTE, selector switch LOCAL via 2
nd level
selector switch
1 potential-free change-over contact, max. 250 V AC, 0.5A (resistive load)
for collective fault signal:
Torque fault, phase failure, motor protection tripped
Voltage output Standard: Auxiliary voltage 115 V AC, max. 30 mA for supply of the control inputs, 3) ,
galvanically isolated from internal voltage supply
Option: Auxiliary voltage 24 V DC, max. 50 mA for supply of the control inputs,
galvanically isolated from internal voltage supply
Local controls Standard: Selector switch LOCAL - OFF - REMOTE (lockable in all three positions)
Push buttons OPEN - STOP - CLOSE
3 indication lights:
End position CLOSED (red), collective fault signal (yellow), end position OPEN (green)
Option: Protection cover, lockable
Functions Standard: Switch-off mode adjustable
Limit or torque seating for end position OPEN and end position CLOSED
Overload protection against excessive torques over the whole travel
Excessive torque (torque fault) can be excluded from collective fault signal
Phase failure monitoring with automatic phase correction
Push-to-run operation or self-retaining in REMOTE
Push-to-run operation or self-retaining in LOCAL
Blinker transmitter signal of actuator can be switched on or off (option)
Options: Positioner 4) :
Nominal position value via analogue input E1 = 0/4 – 20 mA
Adjustable behavior on loss of signal
Adjustable sensitivity (dead band) and pause time
Split Range operation
Motor protection evaluation Standard: Monitoring of the motor temperature in combination with thermoswitches
in the actuator motor
Options: Additional thermal overload relay in the controls in combination with thermoswitches
within the actuator
PTC tripping device in combination with PTC thermistors in the actuator motor
Electrical connection Standard: AUMA plug/ socket connector with screw type connection
Options: Parking frame for wall mounting of the disconnected plug
Protection cover for plug compartment (when plug is removed)
2) The lifetime guaranteed by the manufacturer amounts to min. 2 million cycles. If a higher number of switching cycles is to be expected, thyristor units with virtually
unlimited lifetime should be used
3) Not possible in combination with PTC tripping device
4) Requires position transmitter (potentiometer or RWG) in actuator
