8 TROUBLESHOOTING GUIDE
EXPLOSION HAZARD : The unit must be
powered OFF during the battery installation & must
be in a General Purpose Classified Area before
removing outer plastic tube to prevent the possible
ignition of a hazardous atmosphere.
8.1 Loss of communications
Loss of communications with SELD-102 Node unit
may occur for several reasons:

Unit not powered up

Unit not configured correctly

Unit out of range of receiver

Receiver not configured correctly
See solutions below to each of the possible
causes:
8.1.1 UNIT NOT POWERED UP
1.
4 MAINTENANCE
Verify battery plugged in
(see section
4 MAINTENANCE
on how to turn
on / off unit). If this solves the communication
problem, skip remaining steps.
2. Ensure SELD-102 Node is in a non-classified
area before performing next step.
3. Read battery level using PSP software. If the
battery level is above 2.8V, skip to step 8. If
you are able to successfully read the battery
voltage on this screen but the level is below
2.8V, replace the battery according to
instructions in section
4 MAINTENANCE
.
4. If communications are still not successful,
power down unit by disconnecting the battery.
5. Remove configuration cable.
6. Gently unscrew the external housing (tube)
from the transmitter assembly.
7. Use a voltmeter to read battery voltage across
pins with red and black wires on connector to
battery pack. If the voltage level is below 2.8V,
replace the battery according to instructions in
section
4 MAINTENANCE
.

connection to battery pack cables.
8.1.2 Unit not configured correctly
To perform the diagnostic steps for this issue, the
SELD-102 Node unit will need all sensors
connected to it.
Refer to PSP software instructions to reload the
original configuration into the SELD-103 unit.
8.1.3 Unit out of range of receiver
If communications from the SELD-102 Node unit to
the receiver are still not successful, physically
move the SELD-102 Node unit next to and with a
clear line of sight to the receiver.
If data is being read from this location, then ensure
that the repeater network is appropriately located
and functional.
8.1.4 Receiver not configured correctly
Check receiver configuration to ensure it is set up
to receive data from this particular SELD-102 Node
unit (refer to receiver instruction and operations
manual).
If none of the above solutions are successful in
getting data reception at the receiver, contact the
factory for additional support.
8.2 Inaccurate or missing data
If the data being read from the SELD-102 Node unit
is either inaccurate or missing, this could have
several causes:

Loose cable connections

Unit configuration incorrect

Inaccurate sensor calibration

Incorrect receiver configuration
8.2.2 Unit configuration incorrect
If the inaccurate/missing data problem is across all
sensors, reload the original configuration for the
SELD-102 Node unit (see PSP software user
instructions).
8.2.3 Inaccurate sensor calibration
If the data received on certain channels/sensors is
not accurate, recalibrate those sensors (see PSP
software user instructions).
8.2.4 Incorrect receiver configuration
Refer to receiver instructions to confirm correct
configuration. If necessary, contact factory to
reload receiver configuration settings.
