WIRELESS MONITOR

A small wireless device (about the size of a credit card)
provides a basic approach to wireless monitoring; however, the
device only provides three basic alerts.
Figure 23. Nexus™ Wireless Monitor
The green LED (Generator OK) 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.
The yellow LED (Maintenance Needed) indicates that either
a GENERATOR WARNING is present 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) seconds.
The red LED (Contact Dealer) indicates any one of the
following conditions:
• The Auto/Off/Manual switch on the generator is in the Off
position.
• 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 indicate it has been silenced. The buzzer will not reactivate
until a new alarm has been detected.
The wireless monitor display unit updates the status of its LED's
every 30 to 60 seconds. To conserve power and extend battery
life, the LED's are not lit continuously: instead they are briefly
flashed as indicated above.

PART 1

WIRELESS BASIC TROUBLESHOOTING.

Pairing the Generator Transceiver with the Display Unit
1. See figure 11 for the location of the "Pair/Reset" button on
the display unit.
Place the display unit against the generator transceiver as
shown in figure 10, then immediately press and hold the
"Pair/Reset" button on the display unit
2. Once the yellow LED begins flashing (after about three
seconds), indicating the modules are in pairing mode,
release the "Pair/Reset" button on the display unit and
move the display unit away from the generator transceiver.
3. The Yellow LED will continue to flash during the pairing
process.
4. Once the two modules have successfully paired up the
yellow LED will stop flashing and the green LED will begin
flashing.
5. Press and release the Pair/Reset button to complete the
pairing process. At this time the green LED will stop
flashing and the display unit will enter its normal mode of
operation.
Note: If the Auto/Off/Manual switch is still in the off mode
the red LED will begin to flash to indicate the generator is
in alarm mode. Do not confuse this flashing red LED with
the "failure to pair" described below.
Figure 24. Place the Display Unit Against the Generator
Transceiver
NOTE: The magnets in the display unit activate a magnetic
reed switch in the generator transceiver in step 21. The
relative positioning of the two units needs to be as shown
in Figure 10 to activate the magnetic reed switch.
