8.5.2 Preliminary Checks

Always investigate the failure symptoms fully, prior to taking remedial action. Fault

diagnosis for the equipment operator is limited to the following tasks, since the

operator should NOT remove the covers of the equipment:

1. Check the front panel and web GUI alarm indications to specify the nature of the

fault.

2. Confirm that the equipment hardware configuration is suitable for the purpose

and has been correctly installed and connected (see Chapter 2, Installing the

Equipment).

3. Confirm that inappropriate operator action is not causing the problem, and that

the equipment software set-up is capable of performing the task being asked of

it. If the validity of the configuration, set-up or operation is in doubt, check it (see

Chapter 5, Web GUI Control).

4. Check that the fans are unobstructed and working correctly.

When the failure condition has been fully investigated, and the symptoms are

known, proceed with fault-finding according to the observed symptoms. If the fault

persists, and cannot be rectified using the instructions given in this Reference

Guide, contact Customer Services. Switch off the equipment if it becomes unusable,

or to protect it from further damage.
