Output Short Circuit/Overcurrent

What does ShortCircuit mean?

This diagnostic indicates an output short circuit or overcurrent fault condition exists on an output point. For 5069-IB8S/IB8SK modules, this protection prevents damage to test outputs. When detected, the output faults and turns off, and the I/O Status Indicator flashes red.

• Output point wiring shorted to 24V DC
• Output point wiring shorted to another test output point
• Output point wiring shorted to ground
• Load device drawing excessive current beyond the module's rating

Click steps to track your progress.

1. 1

   Disconnect the load from the affected output terminal.

2. 2

   Use a multimeter to measure resistance between the output terminal and 24VDC, other output terminals, and protective earth ground — expect high resistance (open circuit).

3. 3

   Inspect all physical wiring connected to the affected output for signs of insulation breakdown, mechanical damage, or incorrect connections.

4. 4

   If wiring is clear, test the load device for internal shorts by measuring its resistance.
