ALARM(S)
PROBABLE CAUSE(S)
CORRECTIVE ACTION
SYNTPILO
The synthesizer of the TX
transmitter of the
3G PA-TRX module is
unlocked.
• Power up/down the IDR IDO 3G using the primary
converter's "I/O" switch (Plate 6.IV, item 2 or 9) (wait
until the power supply stops before putting the switch
back to "I").
• If the malfunction persists, check the pilot signal of the
synchronisation board (Sheet P-3) and adjust the
frequency if necessary.
• If the parameters are OK, replace the 3G PA-TRX
module (Sheet E-5) and the cable W20 (Sheet E-1).
• If the fault persists, contact the manufacturer's technical
support service.
CHARGEMENT_
FPGA,
PB_ACCES_
FPGA
Incorrect
3G PA-TRX module
configuration.
• Reconfigure the 3G PA-TRX module (contact the
manufacturer's technical assistance department).
• If the fault persists, replace the PA-TRX module
(Sheet E-5).
• If the fault persists, contact the manufacturer's technical
support service.
SYNTHOL
The 3G PA-TRX module is
not communicating with the
synchronisation board
(communication
interrupted).
• Power up/down the IDR IDO 3G using the primary
converter's "I/O" switch (Plate 6.IV, item 2 or 9) (wait
until the power supply stops before putting the switch
back to "I").
• If the malfunction persists, replace the 3G PA-TRX
module (Sheet E-5), the cable W2 (Sheet E-1) and the
synchronisation board (Sheet E-3).
• If the fault persists, contact the manufacturer's technical
support service.
Other alarm
description
The 3G PA-TRX module
parameters are
inconsistent.
• Power up/down the IDR IDO 3G using the primary
converter's "I/O" switch (Plate 6.IV, item 2 or 9) (wait
until the power supply stops before putting the switch
back to "I").
• If the fault persists, check the parameters of the
3G PA-TRX module (contact the manufacturer's
technical assistance department).
