Troubleshooting
GENERAL ALARM
E2_INVALID
None of the two calibration copies of the internal E2 memory is
valid
E2_INVALID_COPY1
Has not been validated the CRC of the copy #1 of the data of
calibration of E2 memory
E2_INVALID_COPY2
Has not been validated the CRC of the copy #2 of the data of
calibration of E2 memory
E2_CRC_DIFF
The two copies of the data in the internal E2 memory, have a valid
CRC but different from each other
E2_ERROR_UPDATE_CRC
There was an error while updating the CRC of the calibration data
in the internal E2 memory
HW_INIT_FAILED
There was an error during the initialization phase of the machine
NO_LINKS
In the internal E2 memory are not declared the Links (Rx or Tx) to
manage
NO_LINKS_FOUND
The Links to manage are declared, but physically it was not
possible to communicate with any module, so it is assumed that
they haven't been installed
PWR_SUPPLY
Abnormalities were noted in the power supply of the machine.
TEMP
One of the temperature sensors measures a temperature > 60°C
- check if the two fans work properly (check
alarms code 0x02 or 0x03 on the alarm list)
- switch off the MFL for cooling and check the
location temperature
- clean the ventilation grids
I2C0
Error on I2C0 bus
I2C1
Error on I2C1 bus
FAN1
The fan on the left (#1) doesn’t turn
- switch off and switch on the MFL
FAN2
The fan on the right (#2) doesn’t turn
- switch off and switch on the MFL
TEMP_SENS
Communication error with the temperature sensor of the main
board
LOW_BATT
This message informs that the backup battery is running low
LINK ALARM
LINK__NOT_FOUND
I-th link not found. The error is detected in the initialization phase
when attempting to communicate with the E2 memory on the
module to establish if the module is present or not.
Note: The link is not considered valid and therefore will not be
present among those available
LINK__NOT_CONSISTENT
I-th link of type different from that stated in the E2 memory.
Note: The link is not considered valid and therefore will not be
usable
LINK__LASER_E2_INVALID
The I-th link doesn't have a valid calibration memory (none of CRC
of the two copies is correct).
Note: The link is not considered valid and therefore will not be
present among those available
LINK__LASER_E2_INVALID_COPY1
The copy #1 of the I-th link is not valid
LINK__LASER_E2_INVALID_COPY2
The copy #2 of the I-th link is not valid
LINK__LASER_E2_CRC_DIFF
The CRC of the calibration data of the laser module are valid but
different from each other.
Note: The link is not considered valid and therefore will not be
present among those available
LINK__LASER_E2_ERROR_UPDATE_CRC
There was an error while updating the CRC of the calibration data
of the i-th laser module
LINK__RF_FIL_NOT_FOUND
Is declared the presence of the internal RF filter, but is failed the
communication.
Note: The filter is considered not present, therefore the BPF filter is
not present in the items of the transmitters menu (the other filters
are available)
LINK__RF_FIL_E2_INVALID
The internal RF filter has no valid calibration data
Note: The filter is considered not present, therefore the BPF filter is
not present in the items of the transmitters menu (the other filters
are available)
LINK__RF_E2_INVALID_COPY1
The copy #1 of the calibration data of the RF filter is not valid
LINK__RF_E2_INVALID_COPY2
The copy #2 of the calibration data of the RF filter is not valid
LINK__RF_FIL_E2_UNCAL
The two copies of the internal RF filter are valid and the CRC equal
to each other but there are no valid calibration data.
Note: The filter is considered not present, therefore the BPF filter is
not present in the items of the transmitters menu (the other filters
are available)
LINK__RF_FIL_E2_DIFF
The two copies of the internal RF filter are valid but the CRC are
different from each other
Note: The filter is considered not present, therefore the BPF filter is
