Fault Monitoring

Fault Monitoring can be enabled to check runs of passive emitters for shorts or open circuits. This allows the installer to check the channel impedance status of one or more runs of passive emitters. This feature only works on runs with Passive Emitters.  

To start Fault Monitoring, select the system from the Devices and Systems view and then click on Outputs. Open the Fault Monitoring tab and select all or specific Runs to measure by checking the boxes in the left column. Toggle the Monitoring switch on and a warning will pop up with information about masking level changes during measurement. Press 'Yes ' to continue. 

When the process is finished the result will be shown on screen. If no faults (shorts or opens) are discovered, the screen will show an OK status for the runs tested. This is a live test and the system will continue to monitor the impedance status of those runs until the monitoring switch is toggled off. This feature is only available in Qt X software, so once the system is checked and running correctly, it can be toggled off. 

A new snapshot should be taken after any changes to the emitters or the wiring on the runs. Press 'Retake snapshot' to do so.

NOTE: This feature measures the impedance on each channel, so if there is a 'Short' or an 'Open' it will show up on that channel and then all following channels on that Run. 

1. If all channels are showing a fault from the beginning, check the cable connections at the controller, and at the first emitter. Once you have checked the first cable, retake a snapshot to see if the first channel on that run clears.
2. A reminder about the channel designations on the Runs: The first emitter in Run A will be reading from, and reporting status of Channel 2, and the 1st emitter on Run B will be reading and reporting Channel 4's impedance status

Output X – Run A = Channels 2,3,4,1,2,3,4,1,2,3 etc.

Output X – Run B = Channels 4,1,2,3,4,1,2,3,4,1 etc.

If different runs are selected or changes to the system configuration are made it is necessary to retake a snapshot to report the status correctly. A popup warning will also appear indicating a new snapshot should be taken.
