capabilities. The logs are stored on a microSD card
in csv format.
3.2.3.1Connectingtothe USB port
The logs can be retrieved by connecting a computer
to the USB micro-B connector on the NEST main
board. As the NEST is itself certified as a stand-
alone electrical enclosure, the connector is located
behind the back panel for Hazardous Location certification purposes.
IMPORTANT: IT IS NOT RECOMMENDED TO POWER THE DEVICE VIA THE USB PORT, AS THE SUDDEN REMOVAL OF
POWER MAY CORRUPT THE MICRO SD CARD.
3.2.3.2RetrievingtheLogs
The microSD card will appear on the computer as a removable storage drive. Navigate to the drive using the
File Explorer. Copy the logs of interest from the microSD card to a folder on your computers hard drive.
3.2.3.3FormattingthemicroSD Card
From the Main Menu select LOGS and then FORMAT SD CARD to clear all logs from the microSD card.
3.2.3.4microSDCardSpecifications
The NEST will work with microSD cards using either a FAT or FAT32 file system. The NEST ships standard with a 2
GB microSD card rated down to -40C. Larger cards can be used; however, care should be taken in selecting
the SD card for the operating environment. Consumer grade SD cards are typically only rated for tempera-
tures down to -25C.
3.2.4Sensor Lists
When first configuring or adding WASP™ Sensors
to the WASP™ systems, it is necessary to “bind” the
sensors to the receiver. The SENSOR LISTS will show
all available sensors within range of the NEST.
To access SENSOR LIST:
> MAIN MENU > SENSOR LISTS > SELECT.
This brings up the main SENSOR LISTS screen with 3
options: FREE, BOUND, and IGNORED.
FREE: Shows all available sensors within range.
BOUND: Identifies all sensors currently “bound” to
the NEST Receiver.
IGNORED: Identifies all sensors chosen to be ignored
by the NEST Receiver, (if any).
User Manual www.bosspac.com 15

3.2.4.1BindingAndIgnoring Sensor Pucks
To bind a sensor to the receiver, you will need to select a sensor from the FREE sensor list and bind it to the
receiver. To access the FREE SENSOR LIST:
> MAIN MENU > SENSOR LISTS > FREE.
The FREE SENSOR LIST displays all sensors which
have been seen by the receiver, and currently
not bound to the receiver. Each sensor listed is
displayed with list index, sensor serial number, and
the elapsed time since last update.
Example: “1: 1366, 3S” means the NEST received the
last data update 3 seconds ago from the WASP
sensor with serial number 1366.
To bind a sensor, scroll up/down and highlight a
sensor from the FREE sensor list. Once found, tap
SELECT to move to BIND/IGNORE screen.
BIND will add this sensor to this receiver’s data-
base IGNORE will ignore the sensor allowing another
receiver to pick up that sensor. This is useful in large
installations where you may have overlap between
the effective range of sensors and receivers.
After BIND action is selected, you need to select an
input to attach the sensor to. Attaching to an input
allows the information to be pulled for that individ-
ual sensor via MODBUS. The SELECT INPUT screen
will highlight the next “available” input and will also
show the current bound sensor inputs. Choose
SELECT to attach to next available input or scroll to
desired input and SELECT.
The NEST Receiver will request confirmation to bind
the sensor to the selected input, tap YES or NO.
The receiver will jump back to the FREE list screen
after the confirmation allowing this process to be
repeated.
Repeat this process until all the sensors you would
like to bind are bound to the receiver.
2021 16

If you happen to bind a sensor that you should not have - go to SENSOR LISTS. Then choose BOUND and scroll
to find the sensor that should not have been bound. Select the sensor - then choose to IGNORE or REMOVE.
IGNORE places the sensor on the ignored list - it can be bound at a later time.
REMOVE- removes the sensor entirely from the system (until the next packet of information is received) allo
ing another sensor to take its place. There is a functional limit to the number of sensors that can be bound to
the system. If the number of sensors in the area is greater than the functional limit, then the remove feature
should be used to give the wanted sensor a chance to get on the list.
3.2.5Alarm Overide
The ALARM OVERIDE is used to ignore an alarm
during the startup process of the machinery. During
startup, or restart procedure, some machinery may
run rougher than normal. The override provides a
waiting period, (usually about 5 minutes), to allow
the machinery to get into sync, or natural rhythm,
prior to sending out warnings or alarms.
3.2.6Diagnostic
The DIAGNOSTIC info and sensor log are both set to “Disable” as a default.
3.2.7Configuring IndividualSensors
To configure an individual sensor, you must access
that particular sensor’s SENSOR SETTINGS screen.
To access this screen, follow the instructions, start-
ing from the default SYSTEM STATUS screen. First
