Muting Lamp Fault and Short Circuit Diagnostics Triggered
The conditions that are described in this section can trigger the Muting Lamp
Fault and Short Circuit diagnostic on a 5069-IB8S or 5069-IB8SK module
test output point.
Table 20 describes conditions within which the muting lamp fault and short
circuit diagnostics are triggered.
When the conditions that trigger the diagnostics as described in
Table 20 are
corrected, the results are the same as described in
Table 19 on page 102.

• Muting Lamp Points in Module Definition - Point 02, Point 03, or
Point 02 and 03
• Test Output Point Mode - Muting Lamp
• Test Output Data tag = 1
• Test output point is shorted to 24V DC
• Faults
• Turns off
• I.Testxx.ShortCircuit tag = 1
• I.Testxx.Fault tag = 1
• Muting Lamp Fault

• Short Circuit diagnostic = 1
Flashing red
• Muting Lamp Points in Module Definition - Point 02, Point 03, or
Point 02 and 03
• Test Output Point Mode - Muting Lamp
• Test Output Data tag = 1
• Test output point is shorted to another test output point
• Faults
(1)
• Turns off
• I.Testxx.ShortCircuit tag = 1
• I.Testxx.Fault tag = 1
• Muting Lamp Fault
diagnostic = 1
• Short Circuit diagnostic = 1
Flashing red
• Muting Lamp Points in Module Definition - Point 02, Point 03, or
Point 02 and 03
• Test Output Point Mode - Muting Lamp
• Test Output Data tag = 1
• Test output point is shorted to ground
• Faults
• Turns off
• I.Testxx.ShortCircuit tag = 1
• I.Testxx.Fault tag = 1
• Short Circuit diagnostic = 1
• Short Circuit to Ground
diagnostic = 1
Flashing red
(1) This behavior occurs only on the test output point that is faulted.
(2) The diagnostics on the fault test output point are triggered in succession. That is, the Muting Lamp Fault diagnostic changes to 1 and then the Short Circuit diagnostic is triggered.
