Gate Operator System 640-005 For Models HSLG, GSLG-A,
SLG, and SSL
The three-button station located inside the building permits opening
and closing the gate by push button for additional flexibility of operation.
Gate Opener System Sequence:
The vehicle approaches the entrance and driver places the coded card
into card reader or punches digital keypad. This creates an impulse
which actuates the automatic gate operator and opens the gate.As the vehicle
goes through the opening, it passes over the "outer loop"
and "inner loop," creating an impulse to hold the gate open.
When the loops have been cleared, the timer, after a pre-set period,
sends an impulse to the automatic gate operator to "close"
the gate.If the gate is
closing as the vehicle reaches the loop area, the gate reverses to
the open position and the timer automatically resets.
From inside the fence line, the vehicle approaches the exit and passes
over the inner loop. This transmits an impulse to actuate the gate
operator and open the gate. As the vehicle passes over the inner and
outer loops, an impulse is transmitted to hold the gate in an open
position. When the vehicle clears both loops, the timer, after a preset
period, sends an impulse to the automatic gate operator to "close"
