User & Technical Manual
Rev. 1.5 - 08/02/06
must use the exciters menu to perform the changeover in manual mode.
LEDs (Wait, Warning, Fault)
Other signaling LEDs are connected to the alarm states and to
the serial data transmissions that take place among the
microprocessorbased cards. The function of these LEDs is described
further on in this manual.
5.2.3 Analog instruments
The control unit of PJ5KPS contains an analog meter with a rotating selector that are
useful for an immediate display of the following parameters:
FWD PWR
Transmitter direct power
RFL PWR
Transmitter reflected power
UNBAL
Transmitter unbalancing power
PWR EXC1
Power supplied by the exciter currently connected to the amplifier. This
value is measured by the machine in the splitter section
PWR EXC2
Power supplied by the exciter currently connected to the internal load.
This value is measured by the amplifier in the splitter section
EXT FWD PWR
Direct power of an external combiner.
EXT RFL FWD
Reflected power of an external combiner.
EXT UNBAL
Unbalancing power of an external combiner.
These three values are used when the transmitter is connected to a 1+1
system. The SET outputs may also be connected to these quantities.
5.3 First start
This section describes the procedure for powering-on the machine the first time.
For simplicity's sake, the automatic control capacities of the exciters are temporarily
disabled.
Refer to chapter 5.4 that provides the instructions for turning on the PJ5KPS in the
various cases.
5.3.1 Preliminary operation
Before activating this piece of equipment, the necessary connections must be
performed, and in particular:
•
Power supply
• Modulating signals (Audio or MPX, RDS...)
• RF load (antenna feeder or dummy load)
About to the connections of the power supply and the modulating signals, please
refer to chapter 5.1.
