It is the operator's responsibility to perform all safety checks, to
make sure that all maintenance for safe operation is performed
promptly, and to have the equipment checked periodically by
an Authorized Service Dealer. Normal maintenance service and
replacement of parts are the responsibility of the owner/operator
and, as such, are not considered defects in materials or workman-
ship within the terms of the warranty. Individual operating habits
and usage contribute to the need for maintenance service.
Proper maintenance and care of the generator ensures a minimum
number of problems and keeps operating expenses at a minimum.
See an Authorized Service Dealer for service aids and acces-
sories.
Operating instructions presented in this manual assume that
the standby electric system has been installed by an Authorized
Service Dealer or other competent, qualified contractor. Installation
of this equipment is not a “do-it-yourself” project.
HOW TO OBTAIN SERVICE
When the generator requires servicing or repairs, contact an
Authorized Service Dealer for assistance. Service technicians
are factory-trained and are capable of handling all service needs
(1-800-333-1322).
When contacting an Authorized Service Dealer about parts and
service, always supply the complete model number of the unit
as given on the front cover of this manual or on the DATA LABEL
affixed to the unit.
INTRODUCTION
The Nexus Wireless Monitor consists of two transceivers, one
mounted on the generator and the other (display unit) placed in
a convenient viewing location within the home. The system has
a “line of sight” range of about 200 feet, but this will be reduced
when the signal has to pass through walls, floors, etc of a typical
installation.
NOTE:
Some building materials may completely block the passage of
the signal. For example: steel beams, metal siding, foil radiant
barrier insulation.
The Nexus Wireless Monitor indicates the generator status via
three LED’s. The LED’s mimic the three status LED’s mounted on
the home standby generators. The LED operation is described.
This system can be expanded by adding a second display unit to
the system.
BATTERY INSTALLATION
The Nexus Wireless Monitor display unit is powered from two non-
rechargeable AAA alkaline batteries that are installed by removing
the battery cover in the back of the unit. Observe correct battery
polarity which is indicated within the battery compartment. The
expected battery life under normal use is one year when using
standard AAA 1.5V, 1.2ah alkaline batteries.
NOTE:
These batteries should be changed yearly.
The Nexus wireless monitor does not have a power switch, the
monitor automatically powers up when the batteries are inserted.
Refer to the “Installation” section for more details.
NEXUS WIRELESS MONITOR
OPERATION
The Nexus wireless monitor display unit updates the status of its
LED’s every 30 to 60 seconds. To conserve power and extend bat-
tery life, the LED’s are not lit continuously; instead they are briefly
flashed as indicated below.
None of the conditions indicated on the display unit can be cleared
at the display unit. Alarms, warnings, and maintenance alerts all
need to be addressed at the generator.
GREEN LED (GENERATOR OK)
The green LED indicates that either:
• The Auto/Off/Manual switch on the generator is set to the Auto
position, no alarms are present, and the generator is ready to
start and run or is running.
Or
• The Auto/Off/Manual switch on the generator is set to the Manual
position, the engine is running and no alarms are active.
When active, the green LED will flash once every 10 seconds.
YELLOW LED (MAINTENANCE NEEDED)
The yellow LED indicates either a GENERATOR WARNING is pres-
ent or generator maintenance is required. The generator will not be
prevented from running when the yellow LED is on.
When active, the yellow LED will flash once every two (2) sec-
onds.
RED LED (CONTACT DEALER)
The red LED indicates any one of the following conditions.
• The Auto/Off/Manual switch on the generator is in the Off posi-
tion.
• The generator has not been registered.
• A generator alarm is present.
• The Controller has been powered up, but the start up wizard
procedure has not been completed.
If a generator alarm is present the generator will not start and run
in the event of a utility loss, or will be automatically shut down if
the engine is already running.
When active, the red LED will flash once every second.
The internal buzzer will sound once every 30 seconds when the
red LED is on. The buzzer can be silenced by briefly pressing and
releasing the Pair/Reset button; the buzzer will pulse twice to indi-
cate it has been silenced. The buzzer will not reactivate until a new
alarm has been detected.
