Introduction

Safety Considerations

Safety considerations are an important element of proper

troubleshooting procedures. Actively thinking about the safety of

yourself and others, as well as the condition of your equipment, is of

primary importance.

The following sections describe several safety concerns you should be

aware of when troubleshooting your control system.

Status Indicators

When the green status indicator on the analog module is illuminated,

it indicates that power is applied to the module.

Activate Devices When Troubleshooting

When troubleshooting, never reach into the machine to actuate a

device. Unexpected machine motion could occur.
