CLICK 516
• USER GUIDE
Sensor HD and verifies that the duration field in the message is less than 1.9 seconds. If
it is found to be longer than 1.9 seconds, the duration is changed to 1.9 seconds.
The event data message is converted to a contact closure message and passed onto a
Click contact closure card using the Z4 protocol.
In normal state the Click 516 also polls Interval Data from a SmartSensor HD and
checks the speed and occupancy for each lane. The speed and occupancy is tested to
determine if the speed is below the speed threshold and the occupancy is above the
occupancy threshold. If this condition is true, the Click 516 enters HIOCC state; if this
condition is false, the Click 516 stays in NORMAL state.
The eight LEDs on the front of the Click 516 will indicate what state the first eight lanes
are in. If the first LED is on Solid, the first lane is in the Normal state. If the first LED is
flashing, the first lane is in the HIOCC state. This will only work for the first eight lanes.
Note
There are only eight LEDs on the front of the Click 516. This means that only the first
eight lanes will be monitored by the Click 516 front panel.
The LEDs will always come on (starting with the first LED corresponding to the lane
closest to the SmartSensor) regardless of what the lane name is set to. If only two LEDs
are on, then the sensor is only configured for two lanes.
˽ HIOCC State – In HIOCC state, the Click 516 polls event data messages from a Smart-
Sensor HD and verifies that the duration field in the message is greater than 2.3 sec-
onds. If it is found to be shorter than 2.3 seconds the duration is changed to 2.3 seconds.
The event data message is converted to a contact closure message and passed onto a
Click contact closure card using the Z4 protocol.
In HIOCC state the Click 516 also polls interval data from a SmartSensor HD and
checks the speed for each lane. The speed is tested to determine if the speed is above
the speed threshold. If this condition is true, the Click 516 enters NORMAL state; if
this condition is false, the Click 516 stays in HIOCC state.
Note
It takes speed and occupancy to enter HIOCC state. It only takes speed to exit the
mode and return to the NORMAL state.
