Possible cause and recommended solution
1. POWER
gateway or node does
not power on
1.1 no power is applied
The status indicator LED on the device may be off. Apply
power to device, and the status indicator LED should illuminate.
1.2 power source miswired
Verify the device power source is connected correctly and
power is applied.
1.3 wrong voltage
Using a power supply that is outside of the device operating
range could result in permanent damage to the device or cause
it to not work properly.
1.4 node is damaged
If all power settings and connections have been verified, and
the node is still unresponsive, contact LORD Sensing Technical
Support (
See Technical Support on page 48
).
2. COMMUNICATION
no communication to the
gateway or node
2.1 node or gateway has no power
Verify the node and gateway have power applied and that
applicable power switches are on. Power is indicated on both
devices by a status indicator LED.
2.2 node is out of range
Perform a bench test with the node in close proximity to the
gateway to verify they are operational. For range test and
installation recommendations
See Range Test on page 37
.
2.3 node is not in idle mode
Perform Set to Idle command from software. Let it run for up to
30 seconds to see if the node can be reached.
2.4 node is on a different channel
Click on the base station and then Nodes on Other Frequencies
and select the node to move to same frequency as the base
station.
3. DATA ACQUISITION
sensor data is missing
3.1 node is not in sampling mode
Observe the diagnostic data for “node state” to see if the node is
in IDLE, SLEEP, or RUN mode.
3.2 node is out of range
Observe RSSI in the diagnostic data to assure signal strength is
adequate. Increase transmit power to maximum or move
gateways closer if out of range.
3.3 beacon is lost during synchronized sampling
The node will stop sampling if it cannot find the beacon. Assure
the beacon is enabled on the WSDA gateway, and the node is
in good communication range.
3.4 low power
The node will stop sampling if it detects low battery. Observe
