Explanation
47 2047 CAP_TEMP_VAL — Measured capsule temperature value and status.
48 2048 CAP_TEMP_RANGE -50.0 to 130.0°C — High and low range limit values, engineering units, decimal point
place for capsule temperature.
49 2049 AMP_TEMP_VAL — Measured Amplifier temperature value and status.
50 2050 AMP_TEMP_RANGE -50.0 to 95.0°C — High and low range limit values, engineering units, decimal point
place for Amplifier temperature.
97 2097 FLG_TEMP_VAL (Note) — Calculated flange temperature valueand status.
98 2098 FLG_TEMP_RANGE -50.0 to 130.0°C — High and low range limit values, engineering units, decimal point
place for flange temperature.
99 2099 FLG_TEMP_COEFF 0 AUTO Coefficient to calculate flange temperature.
100 2100 FLG_TEMP_PRI 1 AUTO Priority of the flange temperature alarm. (Not used)
101 2101 FLG_TEMP_H_LIM 130 AUTO Threshold to generate Flg Temp High Alarm.
102 2102 FLG_TEMP_L_LIM -50 AUTO Threshold to generate Flg Temp Low Alarm.
103 2103 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.
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
A8.3.7 Parameter Lists for Heat Trace
Monitoring Function
All the parameters for Heat Trace Monitoring
function belong to the SENSOR Transducer block.
