Operation
Operating the RoboSign system
1
Ensure that you are in a safe, central vantage point with a
clear view of both Stop-Go boards and the oncoming traffic.
2
Check that both Stop-Go boards are displaying
STOP
to their
approaching traffic streams. If either unit is not doing this, do
not attempt to operate the system.
3
Observe that the approaching traffic has stopped at both
ends of the work zone and that the shuttle lane is clear.
4
Hold the remote control handset upright at roughly waist height
and press the
OPERATE
button. One of the base units will spin
its board through a half-turn to show a
GO
signal.
5
After an appropriate period of time, and in response to traffic
conditions, press the
OPERATE
button to change to the next
state (see
Operation sequence
right for details).
Note: After each button press, the remote control will ignore
any further presses for four seconds.
6
Repeat step
5
to advance to the next step of the sequence.
One hour standby
If the system is not used for a period of one hour, the base units
and the remote control will automatically switch themselves off to
conserve battery power. Any base unit sign that is at GO will turn
to show STOP.
To re-activate the remote control
• Press the
ON/OFF
button on the remote control.
To re-activate each base unit
• Press the
RESET
button on the base unit front panel.
Fault conditions
During operation if a fault is sensed (such as power loss, radio
interference, etc.), the fail-safe system will automatically ensure
both units are returned to their
STOP
positions and an indication
may be given on the remote control. See the Troubleshooting
section on page 8 for details.
If the system is unable to be operated, the Stop-Go boards can
be removed from the base units and used manually.
Operation sequence
RoboSign systems operate in a strict and coordinated
sequence. Each press of the remote control
OPERATE
button
prompts one of the base units to change to the next step of
the sequence.
For added safety there is a four second delay after every
change of state before the next step of the sequence can be
activated. During the four second period, a further press of
the remote control
OPERATE
button will have no effect.
