Alarms, Diagnostic Tests Troubleshooting

Chapter 5 Troubleshooting and

Diagnostics

This chapter describes alarms, diagnostic tests and troubleshooting for the LRS-24 system.

5.1 Alarms

Audible and visual indicators provide status of alarms and tests at the network, card and port level, and include all links connected to the hub. Alarms are automatically logged and presented upon request, unless otherwise masked.

For more information about alarms, refer to the following sections in Appendix D:

•Displaying General Alarm Status

•Displaying I/O Module Alarm Status

•Displaying Alarms Log.

5.2 Diagnostic Tests

Refer to the diagnostics tests in the Installation and Operation Manual of the individual module.

5.3 Troubleshooting

The front panel displays indicators E1, E2, E3, E4 and E5 that show the current state of the LRS-24 (see Figure 5-1). The states are detailed in Table 5-1.
