General Information
Main Controller
The Power Zone Pro Sync Main Controller (Assembly
No. 10000004337) is the central operating controller for
the Power Zone Pro Sync system. All external modules
are connected to it and communicate with it using CAN
bus (Controller Area Network), Ethernet, or RS-485.
Faults detected by the modules are transferred to and
stored on the Main Controller. The Main Controller
includes an array of inputs and outputs, both digital and
analog. The Main Controller can operate a single
generator in a standalone mode or an MPS (Modular
Power System) to increase the total production of
electrical power.
Display
The Power Zone Pro Sync Display (Assembly No.
10000007810) provides a graphical user interface to the
system. This interface is accessed either directly on the
display or remotely via Ethernet, Wi-Fi, Bluetooth, or RS-
485.
This interface displays information and status from the
system such as trending and logging of parameters. With
the proper secure login, settings can be adjusted, alarms/
events can be set up, voltages and currents can be
calibrated, features can be enabled or disabled, and
firmware can be updated.
Automatic Voltage Regulator Driver (If
Equipped)
The Power Zone Automatic Voltage Regulator Driver
(AVR) (Assembly No. 10000004237) controls the
alternator output voltage by adjusting the exciter field
current. The AVR collects excitation voltage and supplies
the exciter field with the appropriate amount of voltage
and current based on both a target voltage and feedback
voltage provided by the Main Controller over CAN bus.
The AVR runs its own diagnostics on items such as the
excitation input voltage, output exciter field voltage,
output exciter field current, microprocessor internal
temperature, etc. and will communicate to the Main
Controller if any of its monitored values are approaching
their limits. The AVR can also detect when specific
components on the board have malfunctioned and will
communicate that to the Main Controller. The AVR
contains user configurable inputs and outputs, but
system altering should be performed using the Main
Controller. The AVR can operate on both a standalone
generator or in an MPS. In standalone operation, the
AVR regulates voltage. In parallel or network operation,
the AVR regulates power factor/reactive current sharing.
The AVR is powered with regulated 12 V
the Main Controller. It is also indirectly connected to
battery power through its Field Boost Input. The Field
Boost supplies the Exciter with enough field current to get
12
the alternator field started during the startup process.
Field Boost is always on, but is normally negated by the
excitation voltage after reaching nominal frequency.
Three-Phase Automatic Voltage
Regulator Driver (If Equipped)
The
Power
Regulator Driver (3PAVR) (Assembly No. 10000015904)
controls the alternator output voltage by adjusting the
exciter field current. The 3PAVR provides nearly the same
function as the single phase AVR, with the main difference
being the type of excitation voltage the 3PAVR can
regulate. The 3PAVR regulates three-phase excitation
voltage provided by a three-phase excitation voltage
source. It can also regulate single-phase excitation voltage
if necessary. The 3PAVR will supply the exciter field with
the appropriate amount of voltage and current based on
both a target voltage and feedback voltage provided by the
Main Controller over CAN bus. The 3PAVR runs the same
diagnostics as the single phase AVR on its own
parameters. The 3PAVR will communicate to the Main
Controller if any 3PAVR monitored calculations are
approaching their limits. The 3PAVR can operate both on a
standalone generator or in an MPS. In standalone
operation, the 3PAVR regulates voltage. In parallel
operation, the 3PAVR regulates power factor/reactive
current sharing. The 3PAVR is powered with regulated 12
V
supplied by the Main Controller. It is also indirectly
connected to battery power through its Field Boost Input.
The Field Boost supplies the Exciter with enough field
current to get the alternator field started during the startup
process. Field Boost is always on, but is normally negated
by the excitation voltage after reaching nominal frequency.
Governor Driver (If Equipped)
The Power Zone Governor Driver (Assembly No.
10000004238) is used to control the engine speed or to
adjust the sharing of kW power when connected to
another power source. This is done primarily through
either a 12 V
throttle plate on gaseous engines or adjust the fuel rack
on diesel engines. The Governor controls the actuator
position based on a target position received from the
Main Controller over CAN bus. The diagnostics and
measurements
communicated to the Main Controller. Some examples
are heat-sink temperature, actuator position, stuck
actuator, or missing actuator position feedback. The
Governor provides some inputs for customization, but
system altering should be done within the Main
Controller. The Governor can operate on both a
supplied by
standalone generator or in an MPS. In standalone
operation, the Governor regulates speed. In parallel or
network operation, the Governor regulates kW power.
The Governor is powered with regulated 12 V
