Summary RTD Temperature Addresses can contain the following diagnostic codes:
7ffeh = Fail
7ff0h = Not Attached or Not Available
b
RTD Temperature Range Depends on the monitor temperature preference setting:
°C: Low= -50; High =250
°F: Low= -58; High =482
c
Individual RTD Temperature Addresses can contain the following diagnostic codes:
8000h = RTD shorted
7fffh = RTD open
7ffdh = RTD reset
7ffch = SEL-2600 RTD Module Communication Failure
7ff8h = SEL-2600 RTD Module Self-Test Status Failure
7ff0h = RTD Not Attached or Not Available
