FAST RUN TIMER (FULL SPEED RUN TIMER)
A
DIP Switch S1-1 to S1-4
When the gate operator activates, it ramps up and slows down for a fixed
amount of time, but will run at full speed for variable amounts of time
depending upon the settings of the S1-1 to S1-4 DIP switches.
Each DIP switch represents increments of 1/8 second.
When DIP switches S1-1, S1-2 and S1-3 are in the ON position, the Fast Run
Timer is set to 2-3/8 seconds by factory default.
When DIP switches S1-1 to S1-4 are set in the OFF position, the full speed run
time is 1-1/2 seconds.
The longer the operator runs at full speed, the less ramp up and slow down
time. When adjusting, make sure the Fast Run Timer settings DO NOT overrun
the slow down time.
B
SINGLE BUTTON FUNCTION (INCLUDING PULSE RADIO RECEIVER
OPEN/CLOSE)
DIP Switch S1-5
With S1-5 DIP switch in the ON position, the Single Button Function (Command
to Open/Command to Close) will activate, with inputs on terminal 4 and
Common (COM) on the J5 terminal strip. Any of the terminals 9-12 on the J5
terminal strip can be used for common.
When using this feature with the radio receiver (provided), move the radio
wire from terminal 1 to terminal 4 on the J5 terminal strip.
C
CLUTCH OPTION
DIP Switch S1-6
With S1-6 DIP switch in the ON position, and using the Clutch Option; when the
barrier arm is manually forced UP (OPEN), the barrier arm will automatically
CLOSE.
If the Close Loop detects tailgating, the K1 Relay will activate. If an anti-
tailgating alarm is wired into terminal strip (J1), an alarm will sound.
NOTE: When using the Clutch Option, turn DIP switches S1-6 and S2-7 to the
ON position (Auto Close). When this feature is activated the barrier arm will
CLOSE by the timer whenever it is forced UP (OPEN).

HANDING THE BARRIER ARM
DIP Switch S1-7
The J4 Motor Wiring is controlled by DIP switch S1-7. The Handing of the
J
Barrier Arm may be changed from right-hand to left-hand operation by
reversing the factory default motor connections.

NOTE: Right-hand or left-hand operation is determined by facing the
control board with the barrier arm in the CLOSED position. If the barrier arm
is to the right, it is set for right-hand gate operation.
