I am getting the following faults on a TAC 32 unit
1687 CN No POLL Response - The inputs are cleared
1920 Safety Processor configuration invalid - At power up, the CPUa card detects an invalid IOC card safety processor configuration. The SPC command will reconfigure the safety processor.
This happened after a power outage and as soon as we reset the fault log they reappear and will not run. My FGOOD/EBAD light is illuminated red.
