7.0 TROUBLESHOOTING
If trouble occurs with the unit, verify that it meets the basic requirements
listed below. These items should be checked prior to starting any de-
tailed troubleshooting or calling for assistance. All units must have:
•
Adequate and stable primary power
•
Secure cable and wiring connections
•
Proper configuration for the application
7.1
LEDs
The LEDs on the front of installed modules (
Table 4: Module LED
Descriptions
) provide useful information when troubleshooting. Power
and alarm indicators are provided on Platform Manager, Radio, and
Alarm/Relay modules. Radio Modules also have TX/RX LEDs to show
wireless activity.
7.2
Redundant Units
The active radio can be identified by the corresponding LED on the
alarm/relay module as well as the active LED on the radio module. The
active unit is normally selected automatically. For troubleshooting, the
toggle switch can be used to manually set the active radio. Alternatively,
the switch can remain in the automatic position and the active radio can
be selected via the Device Manger UI.
7.3
