Factory Gate
Requirements for a Gate Control System
In many cases, a factory entrance is closed with automatic
gates. Those gates are only opened when vehicles need
to enter or leave the factory grounds. The gate is
controlled by the porter.
The sliding gate is opened and closed by means of a
pushbutton control in the gatehouse. The porter can
monitor the gate operation.
The rolling gate is normally fully opened, or it is closed.
However, gate movements can always be interrupted.
A flashing light is activated five seconds before the gate
moves, and while the gate is in motion.
A safety pressure strip ensures that people are not injured
and that no objects are trapped and damaged when the
gate is closing.
Standard Solution
There are many different control systems for operating
automatic gates. The OPEN and CLOSE buttons initiate
gate movements in the relevant direction, provided it is
not already moving in the opposite direction. Movement
of the gate is terminated either by means of the STOP
button or the relevant limit switch.
