A8.3.6 Status Error
There are three statuses of “GOOD”,
“UNCERTAIN”, and “BAD” for the status of FLG_
TEMP_VAL.
The factor that becomes GOOD/UNCERTAIN/BAD
is as follows.
Good: Normal status
Uncertain: Capsule or Amplifier temperature is
out of range
Bad:
• Capsule or Amplifier temperature sensor
failure
• Capsule or Amplifier EEPROM failure
• Resource block or SENSOR Transducer
block is in O/S mode

Explanation
64 2064 CAP_TEMP_VAL — Measured capsule temperature value and status.
65 2065 CAP_TEMP_RANGE -50.0 to 130.0°C — High and low range limit values, engineering units, decimal point
place for capsule temperature.
66 2066 AMP_TEMP_VAL — Measured Amplifier temperature value and status.
67 2067 AMP_TEMP_RANGE -50.0 to 95.0°C — High and low range limit values, engineering units, decimal point
place for Amplifier temperature.
114 2114 FLG_TEMP_VAL (Note) — Calculated flange temperature valueand status.
115 2115 FLG_TEMP_RANGE -50.0 to 130.0°C — High and low range limit values, engineering units, decimal point
place for flange temperature.
116 2116 FLG_TEMP_COEFF 0 AUTO Coefficient to calculate flange temperature.
117 2117 FLG_TEMP_PRI 1 AUTO Priority of the flange temperature alarm. (Not used)
118 2118 FLG_TEMP_H_LIM 130 AUTO Threshold to generate Flg Temp High Alarm.
119 2119 FLG_TEMP_L_LIM -50 AUTO Threshold to generate Flg Temp Low Alarm.
120 2120 FLG_TEMP_ALM — Status of flange temperature alarm.
Note: The factory default of FLG_TEMP_COEF is 0 so the factory default of FLG_TEMP_VAL indicates the same value as that of
CAP_TEMP_VAL.
