Module Diagnostics and Troubleshooting
Overview This chapter describes troubleshooting the 1769-BOOLEAN module. This
chapter contains information on:
• safety considerations when troubleshooting.
• the module's diagnostic features.
• and module error condition data.
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.
Stand Clear of the Machine
When troubleshooting any system problem, have all personnel remain clear of
the machine. The problem could be intermittent, and sudden unexpected
machine motion could occur. Have someone ready to operate an emergency
stop switch in case it becomes necessary to shut off power to the machine.

ATTENTION
Never reach into a machine to actuate a switch because
unexpected motion can occur and cause injury.
Remove all electrical power at the main power disconnect
switches before checking electrical connections or
inputs/outputs causing machine motion.
