Table 10 - 24V DC Output Power Indicator
State Status Description Recommended Action
Off No power No power is applied. Apply power to this section.
Solid green Normal operation The applied voltage is within specifications. None.
Solid yellow Output power out of specification The output power is out of specification. Check your connectors, wiring, and voltages.
Table 11 - Module Status Indicator
State Status Description Recommended Action
Off No power No power is applied to the power connector. Apply power to this connector.
Solid green Normal operation The module is operating normally. None.
Solid red Unrecoverable fault The module detected an unrecoverable fault. Cycle power to the module. If problem persists,
replace the module.
Flashing red and
green Module is unconfigured Module needs commissioning due to missing, incomplete, or
incorrect configuration. Reconfigure the module. For additional
information, inspect Network Status indicator.
Device in self test The module is performing its power-cycle diagnostic tests. Wait for the module to complete its power-cycle
diagnostics.
Flashing green Idle Idle, waiting for connection from scanner. Establish connection.
Flashing red Recoverable fault The module has detected a recoverable fault. Cycle power to the module or reset the module.
User-initiated firmware update in progress User-initiated firmware update is in progress. Wait for firmware update to complete.
Table 12 - Network Status Indicator
State Status Description Recommended Action
Off Module not online The module does not have an IP address. Verify your network is working properly.
Flashing green Module online with no connections in
established state
The module has acquired an IP address, but no connections are established. Verify your network and module
configuration.
Solid green Module online with connections in
established state The module is operating normally. None.
Flashing red One or more I/O connections in timed-out
state The module detected a recoverable network fault. Verify your network and module
configuration.
User-initiated firmware update User-initiated firmware update is in progress. Wait for firmware update to complete.
Solid red Critical link failure The module detected an error that prevents it from communicating on the
network, such as duplicate IP address has been detected. Cycle power to the module. Check network
IP addressing.
Flashing red
and green Self test The module is performing its power-cycle diagnostic test. Wait for the module to complete its power-
cycle diagnostics.
