Chapter 4 Output Module Features
Output Recovery After Overload or Short Circuit to
Ground Condition
Table 33 describes test output recovery after overload or short circuit to ground
conditions occur.
Thermal Shutoff
Thermal Shutoff helps prevent damage to the output that can result when an
output gets hotter than it can handle.
This feature is directly related to Short Circuit Protection feature. The
increased temperature at the output results from an excessive load at the
output. That is, a load with high current is applied to the output. The high
current heats the output beyond an acceptable temperature and the output
turns off.
Table 33 - Output Recovery - Compact 5000 I/O Safety Output Modules
Cause of Fault Module Operating Conditions Correction Recovery Time
Overload Condition • Output Point Mode - Safety or Safety
Pulse Test.
• Output Data tag = 1.
• Overload current ≥ 1.5 A
Remove the load from the output point. After the condition is corrected, and the output
is returned to the safe state, it recovers in
whichever of the following times is higher:
• 10 seconds
• Output Error Latch Time - This time is set on
the Points category of the Module
Properties dialog box.
To see where to set the Output Error Latch
Time, go to
page 204.
Short Circuit to Ground
Condition
• Output Point Mode - Safety or Safety
Pulse Test.
• Output Data tag = 1.
• Output is connected directly to ground.
Remove the output connection to ground and
set the output to a safe state.
