Demands On The Gate Control System - Siemens LOGO! 24RC Manual

8.5.1 Demands on the Gate Control System

Each gate is opened and closed by means of a cord-op-
erated switch. The gate is normally fully opened or
closed.
Each gate can also be opened and closed using
switches at the gate.
The ASi bus connection enables the gateman to open
and close the gate from the gatehouse. The state GATE
OPEN or GATE CLOSED is indicated in the gatehouse.
A flashing light is activated 5 seconds before the gate
begins to move and continues for as long as the gate is
in motion.
A safety pressure bar ensures that nobody gets injured
and nothing gets trapped or damaged when the gate
closes.
