The GT 710 has two magnetic switches that control the back check location
and monitors the door closed position. The back check magnet must be installed
before the unit is tested. It signals the motor to slow down so the door does not
slam open.
The door closed magnet is optional. It is used to signal the control board that the
door is closed. It is used in applications where a sensor is on the swing side of
the door and wired into the safety with lockout circuit. The switches are closed
by magnets installed by the installer onto the main sprocket gear.
The magnets are not inside the header!
Locate the ¼-inch square and 1-inch long magnets in the parts bag. To position
the magnets, use the appropriate configuration from
Figures 10 through 13
.
Start with the door in the closed position. Place a magnet under the door closed
switch with the white side up. This magnet will deactivate the optional presence
detector as the door begins to open.
Move the door to the 45º position. Place a magnet under the back check switch
with the white side up. The magnet is positioned to move under the switch when
the door is opened to 45º. Use the appropriate configuration from
Figures 10
through 13
. This magnet will command the motor to reduce the door speed to
the setting of the back check potentiometer. Improper placement of this magnet
will cause the door to slam into the door stop.
After
power is applied to the unit and the position of the magnets is “fine tuned”
to make the door functional, the magnets should be epoxied in place following the
instructions on the epoxy packaging.
