Maintenance
5.1: Maintenance
The 6X Series Transmitter is designed with components that require little periodic
maintenance except for the routine cleaning of the filters and the fans in the amplifier
cabinets and trays. For maintenance procedures on vendor items, such as the blower,
heat exchanger, motor, contactor, starter, sensor or flow meter, refer to the
manufacturers’ manuals, included with the item or with the installation material.
The amount of time between cleanings depends on the conditions within the transmitter
room. While the electronics have been designed to function even if covered with dust, a
heavy buildup of dust, dirt, or insects will affect the cooling of the components. This could
lead to a thermal shutdown or a premature failure of the affected tray.
Axcera recommends that the operating parameters of the transmitter be recorded from
the touch screen weekly. It is suggested that this data be retained in a rugged folder or
envelope.
5.1.1: Exciter/Amplifier Assembly
The individual trays in the exciter/amplifier must also be cleaned. If the front panels
become covered with dust, the top covers should be taken off and any foreign material
that has accumulated should be removed. A vacuum cleaner, utilizing a small, wand-type
attachment, is an excellent way to suction out the dirt. Alcohol and other cleaning agents
should not be used unless you are certain that the solvents will not damage any
components or the silk-screened markings on the trays and boards. If water-based
cleaners are used, be careful that the components do not become saturated. The fans and
heat sinks should be cleaned of all dust or dirt to permit the free flow of air for cooling
purposes.
5.1.2: Ethylene Glycol/Distilled Water Cooling System
5.1.2.1: Flushing and cleaning of the strainers
The strainers can be cleaned by flushing them out. Begin the flushing process by
placing a bucket under the drain and opening the drain valve to the strainer. See Figure
5-1.
