Maintenance and
Alignment
5.1 Introduction
This section provides maintenance and alignment information, for the purpose of
routine maintenance and replacement of PC boards and other major components of
the Platinum Z2 FM BROADCAST TRANSMITTER.
5.2 Routine Maintenance
Routine maintenance of the Platinum Z series transmitter basically consists of
regular cleaning and monitoring of temperatures, currents, voltages and faults.
5.2.1 Safety Precautions
It is very dangerous to attempt to make measurements or to replace components
with power on. The design of the transmitter provides safety features such that
lethal voltages are shielded behind doors or clear lexan shields which require a tool
to be opened. Shut off all power before servicing the transmitter, other than
replacement of modules. The Front and rear doors are hinged and can be opened
while the transmitter is running for access to the modules. The modules are “HOT-
PLUGGABLE” which means they can be accessed and removed or replaced
without turning the transmitter off.
5.2.2 Record Keeping
The importance of keeping station performance records cannot be over-emphasized.
Logbooks should be maintained for all operation and maintenance activities. These
records can provide data for predicting potential problem areas and analyzing
equipment malfunctions.
5.2.2.1 Recommended Log Readings
A listing of the recommended meter readings for the transmitter is contained in
Table 5-1 at the end of this section.
