3.1.4 Fusing
For AC modules, the main input fuse is located on the switching power supply mounted to
the carrier PC board and the protective cage can be removed for access to the fuse. For DC
modules, all fusing is located on the carrier PC board.
Always replace any fuse with the same type and rating. Other fuses are present on the
board, and are designed for output fail-safe protection of the system. All output fuse values
are printed on the back of the PC board to aid in replacement.
NOTE : If a fuse does blow in operation, investigate the possible cause of the failure
prior to replacing the fuse, as there is adequate built-in protection margin.
3.2 Preliminary Bench Tests
Prior to installation at the site, it is best to perform back-to-back tests of the entire system
while you have both the Transmitter and Receiver at the same location. Digital STL's have
different parameters for system checks than analog STL's.
Back-to-back bench testing is a good way to become familiar with the SL9003Q system. You
will gain greater confidence in the configuration and likely save a few trips to the
transmitter if the actual interconnecting equipment (such as the remote control equipment
or stereo generator) can be tested at this time.
Figure 3-3 shows a typical setup for bench testing a complete system.
Caution
■ Always operate the transmitter terminated into a proper 50 ohm load.
■ Always attenuate the signal into the receiver to less than 3000 microvolts.
(Failure to observe these precautions can cause the transmitter final amplifier to
be destroyed or the receiver preamplifier to be damaged)
■ Avoid excessive pressure on the audio adjustment potentiometers located on
the back panels of the audio encoder/decoder modules.
