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 Battery Voltage in the bottom left corner
and the current Sign Lamp Brightness in the bottom right corner.
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.

Sign Positioning
The sign must be positioned on reasonably flat, stable ground in a safe position clear of
obstructions, traffic and pedestrians.
Before removing the trailer from the tow hitch of the tow vehicle, the stabilising legs of
the trailer should be deployed to prevent the possibility of the trailer rolling once
unhitched.
Deploy the stabilising legs from their travelling position (horizontal) to their set up
position (vertical) by pulling out the spring loaded leg locking pin, and pivoting the leg 90
degrees until the locking pin re-locks the leg in position.
Wind the leg down until a firm footing is made with the ground.
Note! - All 4 legs MUST be deployed BEFORE raising the mast!

Note: Solar panels should be cleaned weekly (more often depending on environmental factors).
