Diagnostics and Troubleshooting

Overview

The HC900 system incorporates a comprehensive set of diagnostic tools that test hardware and software operation. Diagnostic software elements are contained in each system component. The diagnostic elements that are executed at any given time depend on operating conditions such as current operating mode and the current status of hardware and software. As long as power is applied, each major component of the controller will execute one or more diagnostic elements.

Diagnostics have two functions; they:

Automatically alter system operation to react appropriately to operating conditions (particularly in the event of a system fault).

Provide external indications that enable operating and maintenance personnel to react appropriately when external actions are required.

External Indications of Diagnostic Information

Two sets of diagnostic indicators are provided as standard:

Light Emitting Diodes (LEDs) included in controller hardware. Locations of LEDs are shown in Figure 55; descriptions are given in Table 23 , Table 24, Table 25, and Table 26.

Screen items on:

The Operator Interface connected to the RS485 port

A PC with Hybrid Control Designer connected to the controller module via the RS-232 port or the Ethernet 10Base-T Open Connectivity port.

The LEDs are useful when personnel are performing troubleshooting activities solely at the controller. Also, they are useful for verifying indications viewed as screens items.
