aXis CONTROLLER HOME STANDBY GENERATOR
INSTALLATION
28
Final inspection may require the installation of an emergency
shut down switch, installed and located where Home Standby
Generator Engine (prime mover) can be shut down instantly.
Verify that the (4) Pre-installed 14-2 conductor lugs are free of
corrosion and are fully fastened and spaced properly. Make sure
conductor wires are labeled and/or marked accordingly.
CAUTION
Use a torque wrench to tighten conductors, being sure not to
overtighten, or damage to the switch base could occur. If not
tightened properly, a loose connection would result, causing
excess heat which could damage the switch base.
NOTICE
The aXis Controller™ module is not compatible with standard
Automatic Transfer Switches 100947, 100950, 100952,
101283, and 101380.
Utility Circuit and Generator Power Connections
Conductor sizes must be adequate to handle the maximum current
to which they will be subjected to, based on the 75 degrees
C column of tables, charts, etc. used to size conductors. The
installation must comply fully with all applicable codes standards
and regulations.
Surge protection
CAUTION
Voltage fluctuation may impair the proper functioning of
sensitive electronic equipment.
Electronic devices, including computers and many programmable
appliances use components that are designed to operate within a
narrow voltage range and may be affected by momentary voltage
fluctuations. While there is no way to prevent voltage fluctuations,
you can take steps to protect sensitive electronic equipment.
Install UL1449, CSA-listed, plug-in surge suppressors on the
outlets feeding your sensitive equipment. Surge suppressors come
in single or multi-outlet styles. They’re designed to protect against
virtually all short-duration voltage fluctuations.
AVR = Automatic Voltage Regulator
The AVR is an electrical or electronic device that maintains the
voltage of a power source within predetermined limits. AVR is a
regulator that automatically keeps voltage within the prescribed
range required by the electrical equipment that will be provided
power by the HSB. The AVR uses solid-state semiconductor
devices to smooth out variations in the flow of current.
The AVR monitors the output voltage and controls the input
voltage to the exciter of the generator. By increasing or decreasing
the generator control voltage, the output voltage of the generator
increases or decreases accordingly. The AVR calculates how
much voltage has to be sent to exciter numerous times a second,
therefore stabilizing the output voltage to a predetermined set
point.
There are 3 connectors that come from the AVR. For reference we
have numbered them 1, 2, and 3 when viewed right to left.
1.
Connector #1
(far left), has 4 leads. The 2 leads on the right
side of the connector (top & bottom) are BLUE. They run to
the excitation windings on the stator. The 2 leads on the left
side of the connector (top & bottom) are GREEN (top) and
WHITE (bottom), they run to the sampling windings of the
stator.
