Locking 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 the local STOP control remains active.
Using the “VIEW and SET-UP” features, one can configure different control modes.
The remote controls are optically-isolated (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, one may configure different control modes.
4 WIRES (see the remote connections diagram in Figure 36)
In “4 wires latched” (OPEN, CLOSE, STOP, COMMON) mode with the OPEN or CLOSE signal
switched to ON, the motor is energized and it will continue to run 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 Section 9.1.4, Remote Controls.
3 WIRES (see the remote connections diagram in Figure 37)
With the "3 wires" option (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 continues to run 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 if the signal returns to OFF.
2 WIRES (see the remote connections diagram in Figure 38)
With the “2 wires” option, two 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).
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).
