You re-engage the motor of the operator by turning the
key one full turn in the direction of the gate’s opening.
Remove the key and replace the plug.
General Operating Logic
Given the electromechanical nature of the 412 Operator,
the behavior of the operator when it encounters an
obstacle is always the same
no matter
which
logical
mode of operation has been set on the control panel.
If an obstruction interrupts the gate’s opening, the gate
stops its movement (depending on the weight of the
obstruction) though the motor continues to run its entire
cycle. Sending a signal after the interruption in opening
causes the gate to close.
WARNING!
The pressure the gate leaf applies
to an obstruction is determined by the torque
adjustment setting. It is the installer's
responsibility to make sure the torque is
correctly set.
If an obstacle interrupts the gate’s closing, the gate
stops its movement, though the motor continues to run
its entire cycle. Sending another signal causes the gate
to reopen.
WARNING!
Any triggered reversing or
stopping device prevents an activating
command from being recognized. You cannot
activate the gate to open or close until the
reversing or stopping device has been cleared.
Logical Operating Modes
Note
: Reversing devices are either opening
reversing devices or closing reversing devices,
depending on where the device is connected on
the terminal strip. FAAC strongly recommends
the use of reversing devices no matter which
logic you choose for your gate operation.
The logics available on the 450 MPS control panel are
briefly described below. You can find a complete
description of each logic in the tables on the following
pages.
•
A (automatic):
The gate opens on command
and automatically closes after a pause phase. A
second command on opening is ignored; a
second command during the pause phase
causes the gate to close immediately; a second
command during closing reopens the gate.
•
S (security):
The automatic mode is like A
logic except that a second command during
opening immediately closes both gate leaves.
•
E (semi-automatic):
This mode requires a
command to open and a command to close. A
second command during opening or closing
causes the gate leaves to stop all motion. A
third command then closes the gate.
•
EP (semi-automatic, step by step):
This
mode requires a command to open and a
command to close. A second command during
opening or closing causes the gate leaves to
stop all motion. A third command then
reverses the previous motion of the gate leaves.
•
B (manned, pulsed):
This mode is designed
for guard station use and requires a three-
button switch (pulsed) to open, close, and stop
the gate barrier.
•
C (manned and constant):
This mode is
designed for guard station use and requires at
least a two-button switch (constant pressure
required on each button) to open, close, and
stop the gate barrier (no pressure on a button
stops the gate).
WARNING!
FAAC strongly recommends that
you install a non-contact reversing device for
all gate systems.
WARNING!
Any triggered reversing or
stopping device prevents an activating
command from being recognized. You cannot
activate the gate to open or close until the
reversing or stopping device has been cleared.
