5.5 lock of the 3-position selector
The 3-position selector can be locked in any of
its three positions by means of a padlock�
5.6 reMote control
Place the 3-position selector in REMOTE to
transfer the actuator control to a remote
device� Local OPEN or CLOSE operation will
be inhibited� Only local STOP control remains
active�
using the “VIEW and SET-uP” features may
configure different control modes� The remote
controls are opto-coupled�
A non-regulated 24 V DC voltage (variable from
23 to 27 V DC, max� 4 W) is available on the
actuator terminal board to supply the remote
controls or external devices�
5.6.1 remote commands
using the “VIEW and SET-uP” features may
configure different control modes�
4 wires
(see the remote connections diagram
shown beside)
In “4 wires latched” (OPEN, CLOSE, STOP,
COMMON) mode, with the OPEN or CLOSE
signal switched to ON, the motor is energized,
and it runs on after the signal returns to Off�
To stop the motor, press STOP� To reverse
the direction, press STOP and then press the
button relevant to the opposite direction� The
action of the STOP signal (stop with signal
ON or stop with signal Off) may be reversed
using the VIEW and SET-uP features, see
paragraph

Remote controls�
3 wires
(see the remote connections diagram
shown beside)
With option “3 wires” (OPEN, CLOSE,
COMMON), the actuator can be driven in either
“push-to-run” or “latched with instant reverse”
mode�
In “push-to-run” mode, the actuator can be
driven to the desired position by switching the
OPEN or CLOSE signal to ON� As the signal
returns to Off, the motor is de-energized�
In “latched with instant reverse” mode, when
the OPEN or CLOSE signal switches to ON,
the motor is energized, and it runs on after the
signal returns to Off� If the signal relevant to
the opposite direction goes ON, the actuator
reverses its direction and maintains the new
direction also if the signal returns to Off�

option B3)
The circuits associated to the inputs can be
supplied by the internally-generated 24 V DC
or by an external 20-125 V DC or 20-120 V AC
(50/60 Hz)�
The signal levels are the following:
- Minimum ON signal > 20 V DC or 20 V AC
(50/60 Hz)�
- Maximum ON signal < 125 V DC or 120 V AC
(50/60 Hz)�
- Maximum Off signal < 3 V�
- Minimum signal duration > 500 ms�
- Total current drawn from remote controls
< 25 mA�
2 wires
(see the remote connections diagram
shown beside)
With the “2 wires” option 2 different activities
may be selected:
In “2 wires, signal ON to open”, the actuator
opens if the signal switches to ON and closes
if the signal goes to Off� In “2 wires, signal
ON to close”, the actuator closes if the signal
switches to ON and opens if the signal switches
to Off� This option requires two wires (signal
and common)�
