Connect I/O Power and I/O Cables
ATTENTION: You can configure Test Outputs to be used as standard outputs.
You can connect actuators to Test Output points that are expecting a Standard
configuration.
Test Output points configured as Pulse Test or Power Supply become active
whenever you apply input power to the module. These configured functions are
independent of the I/O connections to the module.
ATTENTION: If a module with Test Outputs configured as Pulse Test or Power
Supply is incorrectly installed in an application where actuators are connected
to these Test Output points, the actuators are activated when input power is
applied.
To prevent this possibility, follow these procedures.
• When installing a module, be sure that the module is correctly configured for
the application or in the out-of-box condition before applying input power.
• When replacing a module, be sure that the module is correctly configured for
the application or in the out-of-box condition before applying input power.
• Reset modules to their out-of-box condition when removing them from an
application.
• Be sure that all modules in replacement stock are in their out-of-box condition.
