OPERATIONAL DATA:
Operation with push-button station:
The following operation is obtained using the low voltage push-
button station (PUL) to control the shutter:
the first press opens the shutter until the end of the motor timer
and the second press closes it; if pressed again before the end
of the motor time, the control unit stops movement whether the
shutter is opening or closing.
A further command restarts motion in the opposite direction.
Operation using different models of Radio Control:
Different models of radio control may be programmed: by
storing a code (1 button) a cyclic step by step operation (Open
- Stop - Close) may be achieved, and by storing two different
codes (2 buttons) separate commands are created, one for
opening and one for closing. Storing three different codes (3
“BeFree” series buttons) produces three distinct commands:
the first for Open, the second for Stop and the third for Close.
Operation using a 1-button radio control:
The following type of operation is obtained using a radio control
with a single button: the first press controls the opening
movement of the shutter until the motor timer stops. The
second press controls the closing movement of the shutter. If
the button is pressed before the motor stops running, the
control unit will stop the shutter moving and the button will need
to be pressed again to reactivate the motor in the opposite
direction.
Operation using a 2-button radio control:
The following type of operation is obtained using a radio control
with 2 buttons: the first button (“Up”, corresponding to the
opening movement) controls opening until the motor stops
running and the second button (“Down”, corresponding to the
closing movement) controls the Closure of the shutter. If the
opening movement is interrupted with another “Up” command,
the motor will continue to run in the upward movement
direction. If, however, the movement is interrupted with a
“Down” command, the control unit will stop the motor.
The procedure is the same for the closing movement phase.
Operation using a 3-button radio control (BeFree series):
The following type of operation is obtained using a radio control
from the BeFree series: the Up button controls the opening
movement until the set motor time has elapsed, the Stop button
makes the shutter stop and the Down button controls the
closure of the shutter. If a stop command is sent during the
opening or closing movement, the control unit causes this
movement to stop. If a command which is the opposite
direction to the current movement is sent during the opening or
closing movement, the control unit causes the shutter to
change direction.
Automatic closing:
The control unit can close the shutter automatically without
sending additional commands.
The selection of this operation mode is described in the Pause
Time programming mode.
DS1 safety device:
The DS1 input anticipates the connection of a general safety
device with contact (NC). If not used, this input must be
bridged.
Action is not taken into account during the opening stage but
causes inverted motor action during the closing stage. Another
safety device operating mode is described in the SEL DS1
Programming section.
DS2 safety device:
The DS2 input anticipates the connection of a general safety
device with contact (NC). If not used, this input must be
bridged.
Action is not taken into account during the opening stage but
causes inverted motor action during the closing stage. Another
safety device operating mode is described in the SEL DS2
Programming section.
DS3 safety device:
The DS3 input anticipates the connection of a general safety
device with contact (NC). If not used, this input must be
bridged.
Action is not taken into account during the opening stage but
causes inverted motor action during the closing stage. Another
safety device operating mode is described in the SEL DS3
Programming section.
Operation with TIMER:
The control unit may be connected to a timer instead of using
the open-close command button (PUL).
Example: at 8:00 a.m. the timer closes the contact and the
control unit opens the shutter; at 6:00 p.m. the timer opens the
contact and the control unit closes the shutter. Between 8:00
a.m. and 6:00 p.m. at the end of the opening phase, the control
