Thenominalworkingprinciple ofaFMtransmitterbasedona hybridcouplerscheme
like HC5-10, foresees that the used amplifiers shall produce the same RF power
that will be added with the same phase. Possible differences in the power level or
phaseof the amplifiersgeneratethe so-called unbalancementpower that isin part
dissipated inside the coupler. The HC5-10 guarantees the overall working of the
transmitter even if one of the amplifiers is completely off-service. In such case, the
powergeneratedbythesurvivingamplifierisroutedtotheantennaanyway;theother
part of the delivered power (that is unbalancement power) is dissipated inside the
combiner.
The HC5-10 is controlled by a microcontroller system, that includes a LCD display
andaseriesofkeysfortheinteractionwiththeuser,thatrealizesthefollowingfunctions:
• Measurementandvisualizationofthe coupler’sworkingparameters
• Activationanddeactivationofthe power output of the system
• Protection of the coupler with respect to potentially dangerous situations like

5.2.5 Functioning Anomalies
Someoperationalconditionscouldcauseawayofwork oftheapparatusnotoptimal.
Anomaly: When at least one of the PJ2000M-C amplifiers doesn't disburse the
same power of the others, the power on "Rej PWR" absorbers resistances could
exceedthethresholdvalueof200W.Ifduringtheoperationalperiodofthetransmitter,
a situation is verified that involves the intervention of the protection with the power
reduction (es.: one of the amplifiers suspends his operation temporarily, while the
otherscontinuesto work), in this casethesystemwith HC5-10 doesn't returntothe
powervalueofRFoutprecedentto this event.
Remedy:Reducethepowerofallthetransmitteradjustingthetrimmer"PowerAdjust",

Remedy: Regulatethesignals phase oftheof the amplifiers untiltoobtain a value
of "Rej PWR" inferior to 200W.
Whenoneof the amplifiers is setin"Local" position, its way ofworkis differentiated

5.2.6 Risks for the personnel
The system HC5-10 with PJ2000M-C amplifiers could also work when one or
more amplifiers have been physically removed from the system.
For the same nature of the type of combiner, the transmitter in RF power it is
possible [potenzialmente] effect the removal of an apparatus maintaining in
operation the transmitter in RF power, without generated signals come of
overloaded that interrupts the functioning of it. Because the physical removal
of an amplifier happens through the [maneggiamento] of the connectors of
RFpowerconnectedtotheamplifier, the operatorshouldhandlepointswhere
it is present RF energy that doesn't come interrupted from circuits of
protection.
For the nature of the adopted combiner type , the removal of an apparatus is
potentially possible maintaining in function the transmitter in RF power,
withoutthatcomegeneratedsignalsofoverloadthatinterrupts the operation.
Because the physical removal of an amplifier happens through the handling
of the RF power connectors connects to the amplifier, the operator would
have handle points where is present RF energy that does not come
interrupted from protection circuits.
In theory the values of RF power in these points are low, but for effect of the
maladjustment of RF impedance that the handling could cause, the power in
the connectors could go up until to very dangerous values.
These operations, therefore, are toAVOID ABSOLUTELY !
5.3 Software
This chapter describes the way the microprocessor system controls the hybrid

The result of this command is that when the HC5-10 is put in OFF mode, the inner
conductorofthe “Alarm” connectorisshorted to ground,sothat the exciter isput in
stand-by mode (this will happen only if provided with an interlock connector, and if
correctly connected with the hybrid coupler).At the same time, the auxiliary mains
outputis opened, so thatifan exciter isconnectedto it, ilwillbe shut off.
