Description
This chapter contains AC Power information for two power
supplies:
Generation 1 (Enable Switch). Part Number 310-0415-002
Outline Drawing 304-0215-004
Generation 2 (Circuit Breaker). Part Number 310-0415-004
Outline Drawing 304-0215-007
An external control and monitor unit may be used to operate the
SSPA ODU series amplifiers. Control and status signals are
accessed via a 32 pin interface connector or an IrDA Interface.
Operating Modes
There are three amplifier operating modes:
•Standby
•Transmit ON
•Fault
Standby Mode
In this mode, the SSPA is ready for main voltage to be applied.
Transmit ON Mode
When transmit is enabled (applied to the SSPA) RF input
signals are amplified.
Fault Mode
Summary Fault
This mode exists anytime a condition detrimental to the SSPA is
detected by the power supply fault detection circuitry. Any of
the following conditions trip the fault detection circuitry:

Operation
MNC-0400-012 4 of 8 Revision D
Power Supply Voltage Fault
The power supply voltage fault circuit will latch immediately
when a fault in one of the three internal power supply voltages
occurs. A voltage fault may be cleared by sending the Fault
Reset command.
SSPA Overtemperature Fault
A SSPA over-temperature fault will clear itself once the
temperature of the base plate is reduced to a safe operating
level. Power supply voltage will automatically be enabled when
the over-temperature fault clears.
Note
An over-temperature fault should be cause for immediate
maintenance action as it is an indication of a fan failure or blocked air
passage(s).
Reverse Power Fault
The reverse Power Fault is set to Active Low when the reflected
power exceeds Prated -7 dB.
Clearing Faults
Faults can be cleared by sending the Fault reset Command (‘B’)
If the fault condition occurs frequently, maintenance action is
required.

Control and Status Signals
Control Signals
AC Power ON
Generation 1 Power Supply
Normal (M&C Interface)
The SSPA is turned on by connecting the AC Cord to the prime
AC power source. ON/OFF control of the AC input is at the AC
power source. The control system turns ON as soon as prime
AC power is applied. The main voltage is turned ON by sending
the appropriate command through the system interface. All
commands are identified in the chapter titled SSPA
Communications and Protocol.
Manual
In manual operation the SSPA is turned ON by connecting the
AC Cord to the prime AC power source. ON/OFF control of the
AC input is at the prime AC power source. The system can be
controlled through the following pins on the interface connector
J1:
•Reset computer — connect Pin h to Pin f (+15 Vdc).
•Normal computer operation — connect Pin h to either Pin Z
(GND)or Pin a (GND).
Note
In manual operation the system is configured to transmit ON when the
prime AC power is on.
Generation 2 Power Supply
The SSPA is connected to the prime AC power source by an AC
Power Cord. ON/OFF control of the AC input is at the AC power
source.
The SSPA is turned ON by connecting the AC Cord to the prime
AC power source. ON/OFF control of the AC input is at the
Circuit Breaker located on the power supply. The system can be
controlled through the following pins on the interface connector
J1:
•Reset computer — connect Pin h to Pin f (+15 Vdc).

MNC-0400-012 6 of 8 Revision D
Initial Turn On
The Initial Turn On procedure has three parts:
•Prepower Check.
•Turn On.
•Turn Off.
This procedure should be followed to ensure proper operation of
the amplifier and to avoid permanent damage to the amplifier.
Caution
Ensure that all of the following instructions are followed. Failure
to comply could result in permanent damage to the amplifier.
Vorsicht
Stellen Sie sicher, dass alle folgenden Anweisungen befolgt
werden.
Nichtbeachtung kann bleibende Schäden am Verstärker
verursachen.
Prepower Check 1. The prime power voltage is within the specified limits of the
amplifier. The correct power input connector pins must be used,
dependent on voltage level and the prime power source. Refer to
the appendix titled Mechanical Drawings for connector pin outs.
2. The amplifier is installed within an enclosure. The exhaust air from
the amplifier should be ducted to the outside of the cabinet so that
the warm air is not recirculated into the amplifier's air intake.
3. The RF output is terminated with a load capable of dissipating the
power of your unit. This load should have a maximum VSWR of
1.5:1. The RF drive signal is within the frequency range of the
amplifier's specification. Refer to the appendix titled Specifications
for rated power gain.
Caution
Do not exceed the RF input power limit as defined in the
product specification. Doing so will cause the SSPA to
overheat. Failure to comply could result in permanent damage
to the SSPA.

Vorsicht
Überschreiten Sie nicht die in der Produktspezifikation
angegebene Begrenzung der HF-Eingangsspannung. Sie
verursachen sonst eine Überhitzung der SSPA.
Nichtbeachtung kann zu einer bleibenden Schädigung der
SSPA führen.
Turn On 1 There are two ways to turn ON the SSPA:
Normal (M&C) Interface) — When operating the SSPA with the standard digital
M&C Interface the system turns ON as soon as prime AC power is applied. The
main voltage is turned ON by sendingthe appropriate command throughthe sys-
tem interface. Refer to the chapter titled SSPA Communication and Protocol for
command details.
Manual — In manual configuration the SSPA will turn ON the control system as
soon as prime AC power is applied. The control system is held in the reset mode
until the J1-Pin h is connected to either
J1-Pin Z or J1-Pin a. This allows the control system to operate normally.
Note
In manual operation the system is configured to transmit ON when the
prime AC power is on.
2. Connect and turn ON a test RF signal source. Slowly increase the
drive power to the amplifier. Monitor the RF output power through
the SSPA’s built-in sampler or through an external coupler.
Turn Off
There are two shut down modes.
Transmit OFF (M&C Interface)
When operating the SSPA with the standard digital M&C Interface the
main system voltage is turned OFF by sending the appropriate command
through the system interface. Refer to the chapter titled SSPA Communication
and Protocol for command details.
System OFF (Manual)
Generation 1 Power Supply
The SSPA is switched off by disconnecting or manually turning
OFF the prime AC power. If you turn the system OFF manually

Operation
MNC-0400-012 8 of 8 Revision D
it will turn ON and be in the same state as it was when you
turned it off.
Generation 2 Power Supply
The SSPA is switched off by turning OFF the prime AC power
using the circuit breaker . If you turn the system OFF it will turn
ON and be in the same state as it was when you turned it off.
