Adjusting the Maximum Green settings

(see page 7), and use the table below:
Distance (metres) 30 75 135 195 300
Green time (seconds)

NOTE: On some controllers the Maximum Green switch may be marked in metres, and the equipment
converts to seconds automatically.

MAXIMUM GREEN
(SECONDS)
Set the Maximum Green times to the appropriate settings.
If substantial queues begin to form and vehicles take more than one
green period to get through the site, then adjust the setting incrementally.
For each new setting allow a few green periods to assess the difference.
It is normal to increase the setting but, if this increases the queue, reduce
the setting, again allowing time to assess the result.
