.2.5 Troubleshooting Guide Related to LED
Status of each individual module can be determined by the status of the LED (MCU, Rectifier,
MCA and FEU). All LEDs should illuminate a green; any other indication requires access to the
Status / Alarm page. Some common a larms a nd there remedies are detailed in the following
sections.
Rectifier Module Red LED or Individual Faults
Any rectifier module fault is remedied by replacing a known good module with the suspected
unit. Reference the Rectifier Module section in Installation Guide for the procedure on Rectifier
Module replacement.
Rectifier Voltage Fault
Measure the AC input and/or DC Output (all 3 fused outputs) and validate that the voltage is
within the specified range detailed.
MCA and FEU Fault
Disable the MCPA to force the sector into bypass, using external measuring equipment validate
the RF passing through the MCPA System. Disable the MCA first then reseat the MCA and FEU
modules, enable the MCPA. When equipment fails to o perate, replace the MCA and FEU with
another module.
MCU Fault
If the communication to the system cannot be established the MCU is not operating. Measure
the +28.5Vdc on the MCU. When MCU fails to operate, replace the MCU.
