8.1 Introduction
This section gives general information on maintenance and electrical adjustments
for the
TEX302TFT
exciter.
Maintenance is divided into two sections depending on the complexity of the
procedure and the test equipment required to complete the maintenance.
8.2 Safety Considerations
When the amplifier is operational, dangerous voltages, high currents, and strong
RF signals are present inside.
CAUTION:
Do not remove any covers without first turning off the device
and make sure you have closed them all before restarting the device.
Be sure to disconnect the amplifier from the mains before proceeding with any
maintenance on the system.
8.3 Ordinary maintenance
The only regular maintenance required for the
TEX302TFT
is periodic replacement
of the fans and cleaning to remove dust in the air filter and any traces inside the
amplifier.
The frequency of these operations depends on the operating conditions of the
device: ambient temperature, level of dust in the air, humidity, etc...
It is advisable to carry out a preventive check every 6 months, and to replace the
fans that make abnormal noises.
The fans should be replaced in case of problems as soon as possible and in any
case at least every 24 months.
