Table 4: Troubleshooting Chart (continued)
Problem
Possible Cause
Corrective Action
8. Incorrect voltageand/or current
reading occurs on the ACE2 front
panel display.
No power.
Fiber optic cable not connected.
Check the Current Voltage Monitor (CVM) power source.
Check the fiber optic connection from the Lamps-Out
Board to the CVM.
9. Low VA
displayed on LCD
panel and all
CCR steps.
CCR shorted
Part of field load is shorted or not
operating.
CCR output may be shorted. Remove the short from the CCR output.
The most common reason for this is an alteration of the field. If this is
the case recalibrate the load using the Lamps-Out Calibration. If that
is not the problem check the field circuit completely and correct any
problems.
10. Periodic IRMS megging is not
being performed
No power.
Fiber optic cable not connected.
IRMS configuration not set
properly.
Verify the IRMS has power.
Check the fiber optic connection from the IRMS to the ACE2
processor board.
Verify the IRMS date, time, and period are set correctly.
The second bank of LEDs indicates communication status and internal processor board diagnostic status. This bank of LEDs
also form binary error codes. These are used by ADB Airfield Solutions to determine board level problems.
