Errors, warnings and other information
Errors
Message Meaning Solution
10MHZ OSCILLATOR
MISSING Sub-assy is missing or
faulty. Insert or change the
sub-assy in the FAB.
10 MHZ OSCILLATOR
THERMOSTAT The sub-assy “10 MHz
oscillator” in the module “IF
unit” is faulty. Change the sub-assy “10
MHz oscillator” and order a
new module (see the
operating manual “DTV 660
transmitter” for the ordering
number of the module).
10 MHZ OSCILLATOR
UNLOCKED 10 MHz oscillator unlocked. Change the sub-assy 10
MHz oscillator in the
module FAB.
10 MHZ REF.
FREQUENCY MISSING The reference frequency for
the up-converter is missing. Check the cabling, the
up-converter and the FAB.
ADDITIONAL AMPL. Error message from
external amplifier. Check the amplifier.
AMPLIFIER CURRENT Power consumption of the
amplifier module is out of
the allowed range. Check fuses of the
amplifier.
Check transistors and
change them.
Change the amplifier.
BLOWER VOLTAGE Blower switched off
because fault is present.
Supply voltage failure Check the module power
amplifier
(DC/DC-converter).
BLOWER SYSTEM Fault in the power amplifier
blower system Check RCU messages for
details
COOLING SYSTEM Fault in the liquid cooling of
the power amplifier system Check RCU messages for
details
COMMUNICATION
DISTURBED Communication between
monitoring program / COM
unit and CPU failed. Switch on the mains.
Check the connections or
check the COM unit.
COMPAT. NUMBER NOT
MATCHING Old version of the
monitoring program. Module hardware / software
is of a higher version than
the CPU software.
EEPROM ACCESS Error in the CPU EEPROM. Change the module CPU.
FPGA ERROR FPGA module does not
work. Restart the transmitter /
change the module.
FREQUENCY
PROCESSING There is a problem in the
IQE. Check the cabling on the
rear-panel OR change the
module.
HARDWARE ERROR Problem in module UPS,
IQE, AU or DSM. Change the module.
INTERFACE DATA
CHECKSUM Checksum (Communication
CPU -RCU) The COM660 database is
corrupted. Please store the
settings for the interface
again.
IIC-BUS BLOCKED I2C-bus error - a module
cannot be accessed. Pull out one module after
the other (except the CPU
and the POWER SUPPLY)
and check when the
message disappears -
change the faulty module.
