7. Maintenance
7.1 Introduction
This section provides general maintenance information and electrical adjustment for
the PJ5000M Amplifier.
Maintenance is divided into categories depending upon the complexity of the
procedure and the test equipment required to complete the maintenance.
7.2 Safety Consideration
When the amplifier is operational, hazardous voltages and high currents are
accessible internally, and there are high power R.F. signals.
Don’t remove any cover without switching off the system first and close all
covers before restarting the system.
Ensure all primary power is disconnected from the amplifier before attempting
equipment maintenance.
FIRST LEVEL MAINTENANCE
7.3 Ordinary Maintenance
The only regular maintenance needed by PJ5000M, is the periodic substitution of
the blowers, and the cleaning of dust filters and any dust accumulated inside the
amplifier.
The time between overhauling of the blowers depends upon several environmental
factors, temperature, humidity, dust pollution etc.
It’s advisable to check the unit every 6 months, and to substitute noisy blowers.
Blowers should be changed as a matter of course at least every 18 months.
