Introduction
This fourth generation AC4S controller provides advanced functions, is easy to operate and
features a
Colour OLED Screen
to show the user the current operation and any diagnostic
information in the event of a failure or low battery situation.
The controls are designed for operation to AS4192-2006.
The controller includes a circuit breaker or isolator that provides for disconnection of power
in the event that service is required or in the event of an overload.
The controller screen displays the current operation mode and a real time mimic of the
Arrow Board lamps, as well as the operation of the Beacons (if fitted).
In addition the screen shows the current incoming

When all operations are turned off the unit enters a low power state until the switches are
operated. The screen brightness is automatically adjusted to suit ambient light conditions.
