DC Bus Monitoring Assembly
The DC bus monitoring assembly is used to generate a PFI signal to shut down control modules in the event of a loss of power. The assembly mounts to the DIN rails on the rear of the power chassis. The DC bus monitoring assembly cable connects to the 5 VDC, +15 VDC, -15 VDC, MCOM, and PFI connectors on the DC power bus bar. It monitors each of these voltages and generates a PFI on failure of any of them. Monitoring of +15 VDC and -15 VDC may be disabled by a jumper.
