Overload Protection

Overload Protection helps prevent damage to a Test Output on the safety input module that can result when more current is present at the output than it can handle.

There is an Overload tag in the Diagnostic assembly.

When an overload or short circuit to ground condition is detected, the Test Output turns off and the I.Testxx.Fault
tag is set to 1.

When an overload or short circuit to ground condition is removed, the Test Output restarts in its commanded state and the I.Testxx.Fault
tag is reset to 0.

For more information on the maximum current that you can apply to a Test Output, see the PointMax I/O System Specifications Technical Data, publication 5034-TD001.

Test Output Recovery After Overload Condition
Cause of Fault	Correction	Recover Time
Overload condition	Remove the load from the Test Output point.	After the Overload or short circuit to ground condition occurs, the Test Output point holds fault indications for 10 seconds until it checks if the fieldfault is removed.
Short circuit to ground condition	Correct the cause of the short circuit condition
