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.
describes conditions within which the muting lamp fault and short
circuit diagnostics are triggered.
When the conditions that trigger the diagnostics as described in
are
corrected, the results are the same as described in

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.
