2) All the timings associated with the two vehicle approaches will always be the
same since they are being controlled by the same phase.
Note that the example above also shows that a second LSLS Output has been configured for Phase
G Green for Audible or Tactile Units. On the IC4 Lamp Monitor Screen the Sensor for this second
LSLS Output has been set to “N/A” to disable Lamp Monitoring on that Output. Therefore, the current
consumed by these Units will not affect the Lamp Monitoring of the Pedestrian Green Signals
(connected to the first LSLS Output), even though both LSLS Outputs are being driven by Phase G
Green. It also shows that the pedestrian amber output has been assigned to a different sensor
(Sensor 8) so that the low power Demand Indicators can be monitored at the same time as the higher
power Red Man signals.
