Chapter 4 Output Module Features
Short Circuit Protection with Safety Output Modules
Table 30 describes what happens when a short circuit condition is detected on
a Compact 5000 I/O safety output module.
Table 31 describes what happens when the short circuit condition is removed
from a Compact 5000 I/O safety output module and the data is set to safe
state, that is, the off state.
For more information on the maximum current that you can apply to an
output, see the Compact 5000 I/O Modules and EtherNet/IP Adapters
Technical Data, publication
5069-TD001.

• Faults
• Turns off
One of the following:
• If the output point is
shorted to 24V DC, the
I.Ptxx.ShortCircuit
tag = 1.
• If the output point is
shorted to ground, no tags
are changed.
One of the following:
• If the output point was
shorted to 24V DC when
the short circuit condition
was detected, the Short
Circuit diagnostic = 1.
• If the output point is
shorted to ground when
the short circuit condition
was detected, the Short
Circuit to Ground
diagnostic = 1.
One of the following:
• Flashes red if the
output point is
shorted to 24V DC.
• Off if the output
point is shorted to
ground.

One of the following:
• If the output point is
shorted to 24V DC, the
I.Ptxx.ShortCircuit
tag = 0.
• If the output point is
shorted to ground, no tags
are changed.
One of the following:
• If the output point was
shorted to 24V DC when
the short circuit condition
was detected, the Short
Circuit diagnostic = 0.
IMPORTANT: You must
cycle power to the module
to reset the diagnostic.
• If the output point is
shorted to ground when
the short circuit condition
was detected, the Short
Circuit to Ground
diagnostic = 0.
Turns off if there is no
longer a load that is
connected to the
output.
