2.2 BASIC OPERATION
Battery power is continuously applied to supply power to the motor and PC board. An
independent "Gate Control" (GC) input is used to operate the gate arm. External switching of
the GC input is required by the user. When the GC input is energized, the gate arm rises from
the horizontal to the vertical position and is then held in the clear position by the electric brake.
When the GC input is deenergized, the electric brake releases and then the arm is driven from
the vertical to the horizontal position. Unlike previous S-type gates, the S-80 drives the gate arm
down from the full vertical to the full horizontal position. Snubbing is only used to control the
gate arm descent in the event of a power loss. A Motor Down pushbutton is provided to use in
