BTS-16110 checks for common faults during operation.

Detected faults are reported on the syslog and returned by the Get Faults VI faults parameter.

faults returns a zero-indexed 7-bit number where each bit is associated with a specific fault. Each fault goes high when triggered. Removing the error condition automatically clears the fault.

The table below provides the fault name and description of each bit.

Table 10. faults Bit Descriptions
Bit Number Fault Name Fault Description
Bit 0 Transducer Status The status output of the connected current transducer. Triggers when a fault is detected within the current transducer, or the current transducer is disconnected.
Bit 1 Power Supply Good Any of the internal power supplies are not good.
Bit 2 Voltage Heater High The temperature in the voltage pocket is above 67 °C.
Bit 3 Voltage Heater Low The temperature in the voltage pocket is below 63 °C.
Bit 4 Current Heater High The temperature in the current pocket is above 67 °C.
Bit 5 Current Heater Low The temperature in the current pocket is below 63 °C.
Bit 6 Time Synchronization Fault TSN synchronization failed.

For example, a fault_field of 5 is the binary number 0b0000101. This value corresponds to faults detected for Transducer Status (bit 0) and Voltage Heater High (bit 2).

Note The zero-indexed 7-bit fault_field is included in the log entry reported by the syslog.
