LED Indicators
LED Indicators provide valuable information regarding the operational state of your CenCom system. There are 3 different sets of
LED’s for 3 different CenCom functions.
Traffic Advisor Indicators
- These LEDs represent Traffic Advisor Output 1 (TA1) thru Traffic Advisor Output 8 (TA8). When a given
output is active or flashing, the state of its corresponding indicator will be one of the following, based on the condition of that particular
output:
On (steady) - Indicates the output is active and not flashing (normal).
On (flashing) - Indicates the output is active and flashing (normal).
Off - Indicates the output is shorted. Turn the CenCom system off, locate and remove the short. Restore power to the system
and activate the output to confirm its proper operation.
Output Indicators
- These represent Outputs 1 thru 7. Each indicator is located directly adjacent to the fuse for that output.When a
given output is active, the state of its corresponding indicator will be one of the following, based on the condition of that particular
output:
On - Indicates the output is active (normal).
Off - Indicates the output is shorted. Turn the CenCom system off, locate and remove the short. Replace the fuse for that output
(with correct amperage rating) and restore power to the system. Activate the output to confirm its proper operation.
