Product Firmware
The L-TRX / L-19F firmware packages are field-upgradable via ELCB. The factory con-
figuration is stored on-board in a write protected memory section. The user can always reload
the factory firmware.
Fluorine Lock
The former fluorine lock option piggy modules have been integrated into a dedicated
deuterium to fluorine up and down converter unit (L-19F). While locking on a deuterated
solvent, the L-19F unit is bypassed. Whereas the L-19F unit translates the deuterium lock
signal into the fluorine lock signal, while locking on samples containing fluorine as lock
solvent.
11.2.2 Protection
Power Supply and Reference Clock Supervision
All power supply voltages and the necessary reference clocks are internally monitored. In
case of a failure the PWR/CLK LED (L-TRX) or the PWR LED (L-19F) are deactivated and an
appropriate error message is generated (if still possible).
Over-Temperature Protection (L-TRX only)
The power amplifier and board temperature are monitored on-board. The ELCB can access
the relevant sensors and act accordingly.
If the temperature reaches the limit of safe operation, the power amplifier is switched off
immediately without intervention of the ELCB. The L-TRX enters the ERROR state. An error
message is sent to TopSpin. See Over Temperature Error [}116].
After regaining normal temperature conditions, the L-TRX reverts to the operating mode prior
to the error.
Over-Current Protection (L-TRX only)
If the power amplifier drain current exceeds the limit of safe operation, it is switched off and
the L-TRX enters the ERROR state. An error message is sent to TopSpin. See Over Current
Error [}116].
11.2.3 Internal Diagnostics
The L-TRX has extensive internal diagnostic functions which can be accessed via the Service
Web. See Service Web [}114].
Many of the diagnostics are performed automatically during power-up and assessed by the
ELCB. If a failure occurs, an appropriate error message is generated.
Due to the low complexity of the L-19F unit, the unit does not have any dedicated diagnostic
functions.
