Maxiva UAX– Operating Voltages
• Transmitters are configurable on-site for single or three
phase AC connection. Loads are split to keep max
components on line if phase is lost.
• If three phase power is used then supply voltage (per
phase) must be between 110 & 240VAC for LPU and 208240VAC for PAB’s.
• Single phase 208 VAC ok with large breaker.
• An optional in-rack AC distribution chassis (Deluxe Rack)
provides individual circuit breaker protection for each AC
input. AC distribution panel not included in Basic Rack.
• Refer to the wiring diagram, AC distribution drawing 8435602-104 for more detail.

LPU Coaxial Switch
• Pins 1, 2 and 3 are used for LPU switching. Pin 2 has +12 V applied to it (comes from TCU, marked
COM on the relay box).
• Pins 1 and 3 normally have 12 V applied (via pin 2) but either 1 or 3 are grounded briefly to make the
switch change positions. Measuring 12 V between case and pins 1, 2 & 3 is normal except during a
switch.
• The relay will switch manually if you ground pins 1 or 3 to the case with a screwdriver

Optional Battery Backup
The battery backup keeps the GPS receiver, 10 MHz OCXO and associated
PFRU circuitry alive for approximately 15 minutes* during a power
failure. Currently under development is a replacement that will keep the
UDC operating for 15 minutes and the PFRU and GPS alive disciplined for
45 minutes.
This is to ensure that when power is restored, the operator does not
have to wait for a GPS re-acquisition or the oscillator to warm back up
and re-stabilize. Saves time on restart.
Operation of this circuitry and battery backup option are recommended
for SFN installations.
*When batteries are new and fresh. These batteries should be
considered a routine maintenance item and replaced at appropriate
intervals.
Replacement every year is recommended.

Additional notes:
** The Remote Control, /Exciter Active, and Auto/Manual Commands are
ignored when in Standalone operation.
The UAX Transmitter will default to Standalone Mode when no connections
are made to the Parallel I/O. If the /TCU Present signal is asserted at anytime,
the Transmitter will be forced into Dual Mode for operations with a TCU. The
Transmitter will remain in Dual Mode until power cycled with the /TCU Present
signal de-asserted.
When in Dual Mode, the Parallel I/O will be disabled when of Remote Control
is Disabled.
When in Standalone Mode, the Parallel I/O will be disabled when Remote
Control is disabled.

Calibration
The multiple calibrations are
used in N+1 applications.
Forward and Reflected are the only
required calibrations.
LPU Forward and PAB # forward and
reflected require use of quantified
couplers, connectors and cables of
adequate power rating (>500W).

• * 0 dBm at this point during power cal when at model number power +1 dB. Use pads as needed.
• µC (micro) compares FPR to current power level then raises or lowers UDC attenuator
• Power increases are done in 50% increments (1 per sec.) until current power is within a few watts
of Forward Power Reference value then stops.
• RF ATTEN DAC value found on teraterm p6 of 7. Values > 500 indicate a problem.
• Power increase should be evident at DAC level >200.
• DAC level is controlled directly in MANUAL mode of operation.
• Pallet currents > 7amps not desirable.
