Terminals 9 and 5 - Obstruction Open (Edge/ Photo Eye Input)
Edge Input: See Programming Section
This input will reverse an opening gate to the close limit.
Activating this input when the gate is closing will have no effect.
NOTE: If upon reversal a second seperate obstruction is detected
(gate edge or RPM sensor), gate will stop and alarm.
Photo Eye Input: See Programming Section
This input will pause an opening gate. Once the input (photo eye)
is cleared, the gate continues to open. Activating this input when
the gate is closing will have no effect.
Terminals 10 and 5 - Obstruction Close (Edge/ Photo Eye Input)
Edge Input: See Programming Section
This input will reverse a closing gate to the open limit. When
reaching the open limit the timer to close, if enabled, will be
disabled until another command is given. Activating this input
when the gate is closing will have no effect. NOTE: If upon
reversal a second seperate obstruction is detected (gate edge or
RPM sensor), gate will stop and alarm.
Photo Eye Input: See Programming Section
This input will reverse a closing gate to the open limit. This input
will not affect the timer to close. Activating this input when the
gate is closing will have no effect.
Terminals 3 and 5 - Stop/Reset Control Input
These terminals are intended for use with a single stop/reset
button or the stop control of a three-button station that is
installed within line of site of the gate. This input functions to
stop the gate or to reset the gate after an entrapment fault.
NOTE: This input uses a normally closed circuit and the operator
will not run until a stop control is installed.
Terminals 4 and 5 - Hard Close Control Input
These terminals are intended for use only with the close control
of a three-button station that is installed within line of sight of the
gate. A momentary activation of this input will cause the gate to
close. Activation of this input for longer than three seconds will
enable the control to be used as a constant pressure override
device. This will allow the user, in emergencies, to override a
failed accessory such as a loop detector or photo-eye.
Terminals 7 and 5 - Hard Open Control Input
These terminals are intended for use only with the open control of
a three-button station that is installed within line of sight of the
gate. A momentary activation of this input will cause the gate to
open. Activation of this input for longer than three seconds will
enable the control to be used as a constant pressure override
device. This will allow the user, in emergencies, to override a
failed accessory such as a loop detector or photo-eye.
